Compare Mowers
Discontinued model in this comparison: John Deere Q850RQuikTrak Stand-On Mower (last listed October 2026). It is no longer sold new, and its price is the last one published rather than one you can pay today. The specifications are still accurate and still worth comparing against.
List prices are the manufacturer’s published figures, re-checked daily; they exclude tax, freight and dealer setup.
A side-by-side reference of each model's stated specifications. MowerFacts doesn’t give opinions: where a published, spec-derived rule can separate machines we mark a Data Pick and show the rule; here, read the values and decide what fits your needs.

What’s different? The 5 differences that matter most, from the published figures.
- Q850RQuikTrak Stand-On Mower has a Tuff Torq TZT13 IHT transmission; V554X has a Pump/Wheel motor transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- Q850RQuikTrak Stand-On Mower holds 12 gal (45.3 L) of fuel; V554X holds 7 gal (26.5 L) of fuel, a 5 gal difference. Tank size bounds how long a machine runs between stops. Consumption varies with engine, load and speed, so hours per tank are not fixed.
- Q850RQuikTrak Stand-On Mower has a published top speed of 12 mph; V554X has a published top speed of 10 mph, a 2 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Q850RQuikTrak Stand-On Mower has a 27 hp engine; V554X has a 24.5 hp engine, a 2.5 hp difference. Published horsepower is the maker's rating at a stated engine speed. It is a different measure from displacement, and two engines of equal rating can pull differently.
- Q850RQuikTrak Stand-On Mower weighs 1,135 lbs (515 kg); V554X weighs 1,176 lbs (533.4 kg), a 41 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Q850RQuikTrak Stand-On Mower's weight means for a trailer ›
