What the specs work out to
Figures MowerFacts computes from Wright’s own numbers — not published by the manufacturer.
Mowing time
- ¼ acre3 min 2 min
- ½ acre6 min 4 min
- 1 acre12 min 8 min
- 2 acres24 min 16 min
- 5 acres59 min 41 min
- 10 acres1 h 58 min 1 h 22 min
About 12 min per acre at 5.09 acres/hour, mowing at 8.8 mph. The second figure is at the published 12.5 mph top speed (7.27 acres/hour) — faster than anyone really mows. About 78.9 acres per tank.

- Towed weight2,160 lb
- single-axle 3,500 lbCarries it, 1,340 lb spare
- tandem-axle 7,000 lbCarries it, 4,840 lb spare
Needs a single-axle 3,500 lb trailer and a vehicle rated to tow at least 2,160 lb.
Gate & trailer fit
- 32 in gateToo wide
- 36 in gateToo wide
- 48 in gateToo wide
Needs at least 79 in of clearance (estimated).
Power & run time
- Power per deck inch0.555 hp/in
- Run time per tank~15.5 h
Mowing times assume 5.09 acres/hour: deck width x 8.8 mph at 80% efficiency, which allows for overlap, turns and trimming. 8.8 mph is 70% of the 12.5 mph top speed Wright publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 12.5 mph, shown so you can see it.
Fit uses the deck width plus 6 in for the discharge chute, because Wright 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 Wright'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.

That is within a single-axle 3,500 lb trailer, and your tow vehicle needs to be rated for at least 2,160 lb.
