Discontinued. John Deere no longer lists the Q850RQuikTrak Stand-On Mower; its page came down around October 2026. These specs stay here because the model still turns up used, and the figures below are the last ones John Deere published. Any price shown is that last list price, not a current one.
John Deere doesn’t publish a list price for this model — it’s dealer quote only. The John Deere product page is the place to start.

What the specs work out to
Figures MowerFacts computes from John Deere’s own numbers — not published by the manufacturer.
Mowing time
- ¼ acre4 min 3 min
- ½ acre8 min 6 min
- 1 acre16 min 11 min
- 2 acres33 min 23 min
- 5 acres1 h 22 min 57 min
- 10 acres2 h 44 min 1 h 55 min
About 16 min per acre at 3.67 acres/hour, mowing at 8.4 mph. The second figure is at the published 12.0 mph top speed (5.24 acres/hour) — faster than anyone really mows. About 44.0 acres per tank.
Weight & hauling

- Towed weight2,035 lb
- single-axle 3,500 lbCarries it, 1,465 lb spare
- tandem-axle 7,000 lbCarries it, 4,965 lb spare
Needs a single-axle 3,500 lb trailer and a vehicle rated to tow at least 2,035 lb.
Gate & trailer fit
- 32 in gateToo wide
- 36 in gateToo wide
- 48 in gateToo wide
Needs at least 61 in of clearance (estimated).
Power & run time
- Power per deck inch0.5 hp/in
- Run time per tank~12.0 h
Mowing times assume 3.67 acres/hour: deck width x 8.4 mph at 80% efficiency, which allows for overlap, turns and trimming. 8.4 mph is 70% of the 12.0 mph top speed John Deere publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 12.0 mph, shown so you can see it.
Fit uses the deck width plus 6 in for the discharge chute, because John Deere doesn't publish an overall width — measure before buying if a gate is tight.
Towed weight adds a 900 lb allowance for a 6x12 open utility trailer to John Deere's published machine weight. Your trailer's own weight is on its VIN plate. Tongue weight, axle placement and your vehicle's tow rating are still yours to check — this is the load, not a loading plan.
Run time assumes a typical 1 gal/hour burn at working load; real consumption varies with engine, load and cut.
