Compare Mowers
Discontinued model in this comparison: John Deere Q850MQuikTrak 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 3 differences that matter most, from the published figures.
- Q850MQuikTrak Stand-On Mower has a Tuff Torq TZT13 IHT transmission; Z554L has a Hydrostatic transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- Q850MQuikTrak Stand-On Mower has a published top speed of 10 mph; Z554L has a published top speed of 12 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.
- Q850MQuikTrak Stand-On Mower weighs 1,095 lbs (496.7 kg); Z554L weighs 1,215 lbs (551.1 kg), a 120 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Q850MQuikTrak Stand-On Mower's weight means for a trailer ›
