Specs are compiled from manufacturer listings and verified buyer reviews and can change over time — please confirm the key details on the product page before buying.
Here is the short answer before you read anything else: match the part number to your deck first, then buy. A belt or blade that is half an inch off will either slip, shake, or chew your spindle housing, no matter how good the steel is. Every pick below is a real Woods-compatible replacement, and each one is here because the fit is confirmed for specific decks. One thing to get straight up front — this list uses flexible, human-like matching for Woods finish mower compatibility. That means not every pick is the exact number you typed into the search bar. The nearest same-type size or the closest matching spec does the same job on the same deck, and each review tells you which decks it covers.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Belts stretch, blades dull, and a mower that sits in the barn all winter needs the right replacement before the first cut. Below you will find the decks each part covers, the measurements that decide whether it bolts straight on, and the honest catch on every option so you can order once and get back to mowing. The right replacement depends on a part number, a measurement, and a deck size — that is exactly what this breakdown of the woods finish mower parts covers from belt to blade.

How To Choose The Best Woods Finish Mower Parts
Ordering a mower part is not like buying a gadget. If the number is wrong, the box arrives and the part does not fit, and you have lost a week of mowing weather. So work in this order: deck model, then part number, then measurement.
Start with the deck plate, not the listing title
Find the model plate on your mower deck and write down the series — RD72, RD7200, PRD7200, RD6000, RM660, RM90 and RM990 all take different parts. A belt listed for a 72-inch rear deck will not run a 60-inch mid-mount deck. The listings here name the decks they fit, so check that name against your plate before anything else.
Match the OEM number when you can
Woods numbers like 18879, 20644, and 1008199 are the fastest way to confirm a match. Cross-reference numbers from other makers matter too — a belt that replaces Woods 18879 and also carries a Scag or Dixie Chopper number was built as a crossover part. If your manual lists a number and the listing lists the same one, you are done.
Measure before you trust the label
Belts are sold by width and length — a 5/8-inch width by 114 3/4-inch length belt is a specific fit, not a universal one. Blades are sold by length, width, thickness, and hole size. Take a tape to your old part. If the belt you pull off measures 133 inches and the listing says 134.13 inches, know that before you order, not after.
Think about how hard your deck works
A finish mower cutting a lawn once a week is easy duty. A grooming mower working rough pasture or a deck running over sticks is not. Heavier blade stock and aramid-cord belts handle the hard duty better. Cheap belts on hard duty is where most of the breakage stories come from.

Detailed Reviews
1. 1008199 Heavy Duty Blades
Our pick — 4.5+★ from 150+ verified ratings; the strongest balance of quality and price.
A three-blade set sized 24.94 inches long for the 72-inch Woods decks, and the one most buyers keep buying.
Each blade measures 24.94 inches long by 2.5 inches wide by 0.25 inches thick, with a 1-inch center hole and 1/2-inch side holes. Each blade measures 24.94 inches long by 2.5 inches wide by 0.25 inches thick, with a 1-inch center hole and 1/2-inch side holes. That width is what the steel of a finish deck wants — the blades you are comparing against here run 24.94 inches against the Oregon set’s 24.2 inches, so you get the slightly longer cut on the same 72-inch deck.
What wins people over is the blade quality itself, which is the thing buyers single out most. Buyers report the edge holds up through rough turf, and the heat-treated high-carbon steel with its anti-rust coating resists chipping when a stick gets under the deck. Mulching comes up more than once as a real improvement over a tired factory blade. On weight, the set lands at 10.93 pounds, against the Oregon set’s 12.2 pounds — noticeably lighter in hand when you are swapping three blades on a hot afternoon.
The honest catch is fit. Fit is the one thing buyers genuinely disagree on, and it is the category you should check hardest before ordering. These are built for the 72-inch standard deck models — RD 72, RD 7200, RD 7200-2 and PRD 7200 — plus John Deere grooming mowers and the X595 where the deck is confirmed at 72 inches. If your deck is a different size, this set is the wrong buy even though the part number matches. Confirm the deck size first, then order.
What the blades get right
- 24.94-inch length, 2.5-inch width and 0.25-inch thickness match the 72-inch Woods deck geometry.
- Heat-treated high-carbon steel with anti-rust coating holds its edge and resists chipping.
- Replaces Woods 1008199 and 1008199KT, plus Stens 345-085 and the John Deere crossover numbers.
- At 10.93 pounds for the set, it is the lighter of the two 72-inch blade sets here.
Where it can trip you up
- Fit is the split issue — it works for the 72-inch decks and not for the others.
- You must confirm your deck is actually a 72-inch unit before ordering.
- Blades arrive unsharpened for finish work and need a light pass before the first cut.
Reach for this if: you run an RD72, RD7200, RD7200-2 or PRD7200 and want the heavier, wider blade set for a finish cut.
Check twice: the deck size — this is a 72-inch part and will not fit a 60-inch machine.
2. Oregon 91-585 Heavy Duty Blades
Genuine Oregon steel in a three-pack, built for the same 72-inch decks and cutting clean through weeds and grass.
These are genuine Oregon replacement blades, bulk packed, part number 91-585. These are genuine Oregon replacement blades, bulk packed, part number 91-585, and they carry the same Woods cross-reference numbers as the set above — 1008199 and 1008199KT. What owners mention is simple and specific: the blades cut weeds and grass evenly and live up to the advertisement. On a 72-inch finish deck, even cutting through weeds and grass is the job.
Sizing is where these differ from the top pick. Each blade runs 24.2 inches long and 1 inch wide, against the other set’s 24.94 inches long and 2.5 inches wide. The Oregon set also carries the weight — 12.2 pounds for the three, against 10.93 pounds — so it feels denser and heavier in the hand. Both fit the RD72, RD7200, RD7200-2 and PRD7200 line, so the choice between them is brand loyalty and blade profile, not fit.
Oregon’s own advice on the box is worth following: check your owner’s manual for the correct part number and the correct installation before you bolt anything on. Blades installed upside down cut badly and shake hard, and that is a buyer mistake, not a part fault. Install them right and they run true.
The Oregon edge: a genuine OEM Oregon part with the full Woods cross-reference list, which takes the guesswork out of matching it to your deck.
The trade: a narrower 1-inch blade profile and a heavier 12.2-pound set than the top pick, which some owners feel in the spindle load on a light deck.
Order this one if you want the genuine Oregon stamp and a blade profile closer to the original factory cut.
Think twice if your deck plate does not list 72 inches — this set does not cover the 90-inch grooming decks.
3. Set of 6 Blades for Woods RM90
Six blades in one box, because a 90-inch grooming deck does not run on three.
Most of this list is 72-inch territory — this set is not. It is a six-blade kit for the Woods RM90, RM990 and P990 90-inch grooming finish mowers, replacing part 24590KT. If you own one of those wide grooming decks, the three-blade sets above are simply the wrong quantity, and this is the box that gets your deck fully rebuilt in one order.
The numbers here are practical. Six blades total, 13.27 pounds for the whole set — a little over two pounds per blade, which is the weight class a grooming deck wants for rough ground and tall growth. The part number is 91-767, and the listing dimensions sit at 24 by 4 by 3 inches for the packed set, so it is a compact box that stores on the shelf until you need it.
Here is the thing to know before you buy: this listing carries no customer review data, so there is nothing to report about how these behave in the field. That is not a knock on the blades — it is a straight fact about the listing. Buy it on the part number and the model fit, both of which are stated, and confirm 24590KT against your manual. This is the pick where matching the number matters more than anything else in this article.
Why it earns a slot: a complete six-blade kit for the 90-inch grooming decks — RM90, RM990 and P990 — replacing 24590KT, which no other pick here covers.
What to weigh: no owner feedback exists on this listing, so your confidence has to come from the part number and your own manual, not from other buyers’ experience.
The right box for: RM90, RM990 or P990 owners who want all six blades replaced in one go.
Not your part if: you run a 72-inch deck — six 90-inch blades are the wrong size entirely.
4. UDC Parts 18879 Deck Belt
The belt most 72-inch Woods owners end up buying, with aramid cord and a one-year support promise.
A 72-inch deck under load pulls hard, and a belt is the part that takes the punishment. This one replaces Woods 18879 and 18879RP, and it measures 0.63 inches wide by 134.13 inches long — the same size the OEM belt carries. It is built with aramid tensile cords, a natural rubber body, and a two-layer wrapping cover, designed with a tolerance of ±0.40 inches on length. That tolerance note matters: it tells you slight length variation is normal and does not affect how the belt runs.
Fit is the reason this pick is here, and it is the strongest part of its record. It fits the RD72, RD7200, PRD7200, TBW240 72-inch and TBW180 72-inch decks — rear deck only. The crossover goes further than Woods too, and owners have put it to work on other 72-inch rear-discharge machines. Replacement quality is the other thing people bring up: it goes on and matches the description as written.
The trade-off is honest and worth knowing. Durability is the one thing that splits opinion on this belt. Some owners get seasons of service and some report a belt that breaks inside two months and starts coming apart. The size can also vary — a small number find theirs measures about 2 inches long. On a rear deck that fits well, this belt performs. If you are running a deck under constant rough load, watch the tension and the routing and buy a spare. The one-year product support for manufacturing defects is a real backstop.
Why it earns the premium slot
- 0.63-inch width by 134.13-inch length — the same belt size as the OEM 18879.
- Aramid tensile cords, natural rubber body and two-layer wrapping cover for strength and flex.
- Fits RD72, RD7200, PRD7200, TBW240 72-inch and TBW180 72-inch rear decks.
- One year of product support for manufacturing defects.
The honest side
- Durability splits owners — some see long life, some see a belt that fails early.
- Length can vary; a few find theirs about 2 inches long.
- Rear deck only — this is not the belt for a mid-mount 60-inch deck.
Buy it for: a 72-inch rear-discharge Woods deck that needs the OEM-size belt at a lower tier.
Spare belt advice: keep one on the shelf — belt failure is the split issue on this part, and a spare keeps the deck running.
5. Woods Rm660 Rd7200 Finish Mower Belt 18879 Woods Brand
The genuine Woods belt, same 18879 part number, for the owner who will not run a copy.
This is the one box in the article stamped with the Woods name on it, and it carries part number 18879 — the same number the UDC belt replaces. It is listed for the RM660 and RD7200 finish mowers and the PRD7200, and it measures 134.13 inches long by 0.63 inches wide. Same size as the premium pick above, different maker. It is listed for the RM660, RD7200 and PRD7200 finish mowers at 134.13 inches long by 0.63 inches wide.
The record on this belt is clean. Quality is the thing buyers talk about most, and the fit follows close behind — it goes on the deck and works. Installation comes up as well, and the consistent word is that it goes on without a fight, which matters on a belt that has to route around tight pulleys and a tensioner. On a belt this long, a stiff one can fight you for an hour.
Weigh the two belts honestly. The UDC belt above costs less and carries a one-year support promise. This one costs more and carries the Woods name. Neither is wrong. If your machine is a working unit and you want the exact factory part, buy this. If you want the same size belt at a lower tier, the UDC is the smarter order — and it is the one more owners have tried.
The genuine-part case: a Woods-branded 18879 belt, 134.13 inches long and 0.63 inches wide, listed for RM660, RD7200 and PRD7200 decks.
What the premium buys: the Woods name and a factory part, at a tier above the crossover belt of identical size.
Worth it if: you insist on the genuine Woods belt for a working RM660 or RD7200.
Look elsewhere if: you are comfortable running a crossover belt — the UDC is the same size and the same part number for less.
6. Woods Prd6000 Rd6000 Blade Kit
A genuine OEM blade kit for the 6000-series decks, sold on the part number alone.
You are looking at a factory Woods kit here — part 1001513KT, built for the PRD6000 and RD6000 finish mowers. It is a factory Woods kit, part 1001513KT, built for the PRD6000 and RD6000 finish mowers. This is the OEM replacement, listed as such.
The listing is thin. There are no blade measurements listed and no published review data to pass along, so I cannot tell you blade length or weight for this kit. What I can tell you is the part number and the models: 1001513KT for the PRD6000 and RD6000. If those match your machine, the kit is the right one. If your deck is a 72-inch RD7200, this is not your part — the 72-inch decks take a different blade entirely.
Order this one on the number. Check the part number in your owner’s manual against 1001513KT, confirm the deck is a 6000 series, and you have done all the research this listing allows. With no published sizes or owner reviews on this listing, the OEM number is the only confirmation available.
Reach for this if: you run a PRD6000 or RD6000 and want the genuine Woods 1001513KT kit.
Know before you order: there are no published sizes or owner reviews on this listing — the part number is your only confirmation.
7. 5WP1001244 Mower Drive Belt
A 118-inch deck belt with aramid cord, cut for the RD6000 and the John Deere GM1060R.
The 6000-series decks take a shorter belt than the 72-inch machines, and this is the one. It measures 118 inches long by 0.63 inches wide, and it replaces OEM numbers 5WP1001244, 1001244 and 31615. It fits the Woods RD6000 finish mower and the John Deere GM1060R — a crossover note if you keep both colors of machine in the shed.
Quality is what earns this belt its slot, and it is what buyers point to first. The construction is reinforced with a layer of aramid cords for tensile strength and heat resistance, which is the part that matters under the constant pull of a 6000-series deck. Fit follows close behind in owner experience, and installation comes up as unexpectedly easy for a belt this long. The claim from the maker is no-slip performance and constant blade speed under changing grass loads — that is a maker claim, not a measured figure, so take it as the design intent.
The honest catch is durability over time. Most owners have a good run with it, but there is a split in experience — some belts have given out around the three-month mark. That is not every belt, and on a deck with a tight tensioner it may be a setup issue as much as a part issue. Check your tension and pulley alignment when you install, and the odds improve.
What makes it the fit match: 118-inch length and 0.63-inch width, replacing 5WP1001244, 1001244 and 31615, for the RD6000 and the John Deere GM1060R.
The risk to know: a smaller group of belts has failed early — a three-month lifespan is reported, so setup and tension matter.
Fit for: an RD6000 or a GM1060R that needs the 118-inch replacement with aramid cord.
Install advice: check tensioner alignment on day one — early belt failures on this part tend to trace back to the run, not the belt.
8. Lawn Mower Deck Belt 20644
The crossover belt that pulls double duty across Woods, Scag and Dixie Chopper decks.
This belt is the cheapest way onto a Woods deck in this article, and it covers more machines than any other belt here. It measures 5/8-inch wide by 114 3/4-inch long and replaces Woods 20644 and Scag 48799, plus Dixie Chopper 2006B112R. On the Woods side it fits the RDC54 and RD60 rear-discharge decks and the RM550 rear-mount decks. On the other side of the crossover it fits Scag SMZ-48 and SSZ 48-inch decks, plus Dixie Chopper Magnum, Iron Eagle, Classic and Silver Eagle with 50-inch decks.
Fit is the thing buyers praise most on this belt, and it is the reason it earns a slot. It goes on and lines up. The material is aramid, and the belt weighs in at 2 ounces — light enough to coil into a small box and keep as a spare. If you run more than one machine, one of these on the shelf covers a lot of ground.
Be straight with yourself about the durability. That is the split on this belt — some owners get a long life out of it and some see it break after several hours of use. Quality and value get the same split treatment. At this tier, that is the honest expectation: a crossover belt that fits well and may not last like a premium one. Buy it as the budget replacement or the backup, not as the belt you expect to run for seasons.
The crossover value: one 5/8-inch by 114 3/4-inch belt that replaces Woods 20644, Scag 48799 and Dixie Chopper 2006B112R.
The reality check: durability is the split issue here — hours of hard use can end this belt, so treat it as a budget replacement.
Grab it if: you want a spare that covers an RDC54, RD60 or RM550, plus Scag and Dixie Chopper decks in the same box.
Not for: a 72-inch deck — 114 3/4 inches is too short for that belt run.
Know the Specs
Belt width and length — the two numbers that decide fit
A deck belt is sold by width and length, and both have to match. Width is written in fractions or decimals — a 5/8-inch belt and a 0.63-inch belt are the same width, just written two ways. Length is the long number, usually 114 3/4 inches, 118 inches, or 134.13 inches. Order the wrong length and the belt either will not reach the tensioner or sits too loose and slips. Measure the old belt flat and relaxed, then check the number against the listing.
Aramid cord — what it does for a belt under load
Aramid is the strong fiber woven inside the belt as tensile cord. It gives the belt its pulling strength and its heat resistance, which is the part you feel on a long cut in tall grass. Natural rubber forms the body, and a two-layer wrapping cover protects the cord from wear. A belt built this way is designed to hold its shape under load — and a belt sized with a stated tolerance, like ±0.40 inches, tells you small length variation is normal and does not hurt performance.
Blade length, width and thickness
Blades are sold by cut length, blade width, and thickness, plus the size of the center hole. A 24.94-inch blade belongs on a 72-inch deck; a smaller deck takes a shorter blade. The center hole has to match your spindle bolt exactly, or the blade will not seat. Thickness tells you how much steel you have before the edge dulls away — a 0.25-inch blade is heavier stock than a thinner one and holds up better in rough turf.
OEM numbers and crossover parts
The OEM number is the factory’s own part code — 18879, 20644, 1008199, 1001513KT. A crossover part lists several numbers because the same belt or blade was used across brands. When a listing carries the same OEM number your manual lists, you have a match. When it carries a crossover to another brand, check the deck size on that machine as well, since a belt that fits one 50-inch deck will not fit a 72-inch one.

The Bottom Line
For most people shopping for woods finish mower parts, the winner is the 1008199 Heavy Duty Blade Set because it covers the 72-inch decks most owners run, with a 2.5-inch wide blade and a lighter 10.93-pound set than the Oregon alternative. If you want the genuine Oregon stamp, order the Oregon 91-585 set. For a 72-inch rear deck that needs a belt, the UDC 18879 is the one to reach for — the same 0.63-inch by 134.13-inch size as the OEM, with a one-year support promise behind it. And if you own a 90-inch RM90, RM990 or P990, grab the six-blade kit and rebuild the whole deck in one order.
The 1008199 blade set and the UDC 18879 belt both carry the strongest fit records in this guide, across the 72-inch decks they cover. Match your deck size and part number first, and order the blade or belt that clears both. Matching deck size and part number before you order is what keeps the mower cutting instead of waiting on a return.
