What the specs work out to
Figures MowerFacts computes from Troy-Bilt’s own numbers — not published by the manufacturer.
Mowing time

- ½ acre16 min 12 min
- 1 acre33 min 23 min
- 2 acres1 h 6 min 46 min
- 5 acres2 h 45 min 1 h 55 min
About 33 min per acre at 1.82 acres/hour, mowing at 4.9 mph. The second figure is at the published 7.0 mph top speed (2.6 acres/hour) — faster than anyone really mows. About 6.4 acres per tank.
Gate & trailer fit

Needs at least 52 in of clearance (estimated).
Power & run time
- Power per deck inch0.478 hp/in
- Run time per tank~3.5 h
Mowing times assume 1.82 acres/hour: deck width x 4.9 mph at 80% efficiency, which allows for overlap, turns and trimming. 4.9 mph is 70% of the 7.0 mph top speed Troy-Bilt publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 7.0 mph, shown so you can see it.
Fit uses the deck width plus 6 in for the discharge chute, because Troy-Bilt doesn't publish an overall width — measure before buying if a gate is tight.
Run time assumes a typical 1 gal/hour burn at working load; real consumption varies with engine, load and cut.
