Read the full review
Exmark describes a genuine factory V belt, part 126-7443-SL, replacing previous part 126-7443, for 52 inch Radius E-Series, S-Series and X-Series decks, with model numbers listed for each series. The spec table states a warranty of 90 days, parts only, and an item weight of 1.8 pounds. Two points need care: the spec table lists Compatible Devices as UTV while the title and bullets describe an Exmark mower belt, and the spec table gives item dimensions of 16 x 10 inches without a belt length or width, so this article uses the title and bullets and states no belt size.
Pros
- Genuine Exmark factory part number is stated
- 90 day parts warranty is stated
- Fits Radius E-Series, S-Series and X-Series 52 inch decks
- Replacement for previous part 126-7443 is stated
Cons
- No belt length or width is stated
- Spec table lists Compatible Devices as UTV, not a mower
- Material is listed as plastic in the spec table
- Warranty covers parts only

Exmark describes a genuine factory V belt, part 130-0843-SL, replacing previous part 130-0843, for 54 inch Quest E-Series and S-Series decks, with model numbers listed for each series. The spec table states a warranty of 90 days, parts only, and an item weight of 12.96 ounces. Two points need care: the spec table lists Compatible Devices as UTV while the title and bullets describe an Exmark mower belt, and the spec table gives item dimensions of 16 x 10 inches without a belt length or width, so this article uses the title and bullets and states no belt size.
Pros
- Genuine Exmark factory part number is stated
- 90 day parts warranty is stated
- Fits Quest E-Series and S-Series 54 inch decks
- Replacement for previous part 130-0843 is stated

Buying guide: best deck belt for exmark zero turn
Match the deck width first
Deck width comes first because a belt made for one width does not fit another. The Winwon and Exmark 126-7443-SL listings state 52 inch decks, the Exmark 130-0843-SL listing states a 54 inch deck, and the GEATaaT listing states a 60 inch deck. Width alone does not settle the fit, since the 52 inch listings serve different series, so the part number must be checked next.
Match the part number, not just the deck
Part numbers are the surest match in these listings. The Winwon listing replaces 109-4994 and 116-1966, the GEATaaT listing replaces 109-8073, 135-5774, 116-1985 and 146-0183, and the Exmark listings carry their own factory numbers, 126-7443-SL and 130-0843-SL. See the drive belt for zero turn mower guide for the wider belt picture.
Belt size and material
Only the replacement listings state a belt size: Winwon at 5/8 x 186 inches and GEATaaT at 5/8 x 199 inches. The Exmark listings state no belt length or width, so their size cannot be checked from the listing. Materials differ too: rubber for Winwon, aramid for GEATaaT, and plastic listed in the spec table for both Exmark belts.
Warranty and genuine parts
The Exmark listings are genuine factory parts with a warranty of 90 days, parts only, stated in the spec table. The Winwon and GEATaaT listings state no warranty term, so warranty cannot separate those two. A genuine part number with a stated warranty is the safer line to check when the belt size is not stated.

Read the manual, keep children and pets out of the yard while you work, wear eye and hearing protection and sturdy footwear, and never exceed the slope rating of your machine. Refuel only with the engine off and cool. See CPSC lawn mower safety. Read our Safety Disclaimer.
Matching It to Your Property
- Match the deck width: 52, 54 and 60 inch decks each need their own belt in these listings.
- Match the series: Lazer Z, Radius and Quest decks use different part numbers here.
- Check the serial range where stated: the Winwon listing fits serial 790,000 and higher.
- Check the warranty line: only the Exmark listings state a term, of 90 days, parts only.
The Acre Score explained
The Acre Score weighs five factors: performance, build quality, value, safety and warranty. Safety here means stated safety features or certifications, and none of these listings states one. 2 listings state a warranty term of 90 days, parts only, while the other 2 state none. How we pick explains the weights.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Exmark 126-7443-SL | 9.6 | 28 | 20 | 20 | n/a | 2 |
| Exmark 130-0843-SL | 9.6 | 27 | 20 | 20 | n/a | 2 |
| GEATaaT 109-8073 | 9.6 | 29 | 21 | 21 | n/a | 0 |
| Winwon D5D018 | 9.6 | 28 | 20 | 20 | n/a | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
FAQ: mowing large lots
Which belt fits a 52 inch Exmark deck?
Two listings state 52 inch decks, but for different series: Winwon for Lazer Z and Lazer Z AS mowers, and Exmark 126-7443-SL for Radius E-Series, S-Series and X-Series decks. Match the series as well as the deck.
What belt size does the GEATaaT listing state?
5/8 x 199 inches, with an aramid material and a V-belt style. The Winwon listing states 5/8 x 186 inches, so the two replacement belts differ in length.
Do the Exmark belts state a belt length?
No. The Exmark listings state part numbers, deck widths and series fits, but no belt length or width, so size cannot be checked from those listings.
Which belts state a warranty term?
The Exmark 126-7443-SL and 130-0843-SL listings state 90 days, parts only. The Winwon and GEATaaT listings state no warranty term.
Can one belt fit every Exmark deck?
No. Deck widths, series fits and part numbers differ across these listings, so one belt cannot cover every Exmark deck. Match the deck width, the series and the part number together.
