What the specs work out to
Figures MowerFacts computes from Gravely’s own numbers — not published by the manufacturer.
Mowing time
- ¼ acre8 min 6 min
- ½ acre16 min 11 min
- 1 acre32 min 22 min
- 2 acres1 h 3 min 44 min
- 5 acres2 h 38 min 1 h 50 min
About 32 min per acre at 1.9 acres/hour, mowing at 4.9 mph. The second figure is at the published 7.0 mph top speed (2.72 acres/hour) — faster than anyone really mows. About 6.6 acres per tank.
Weight & hauling

- Towed weight1,579 lb
- single-axle 3,500 lbCarries it, 1,921 lb spare
- tandem-axle 7,000 lbCarries it, 5,421 lb spare
Needs a single-axle 3,500 lb trailer and a vehicle rated to tow at least 1,579 lb.
Gate & trailer fit
- 32 in gateToo wide
- 36 in gateToo wide
- 48 in gateToo wide
Needs at least 54 in of clearance (estimated).
Power & run time
- Power per deck inch0.448 hp/in
- Run time per tank~3.5 h
Mowing times assume 1.9 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 Gravely 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 Gravely 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 Gravely'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.

What size trailer do I need for the Gravely ZT X 48 KAWASAKI?
At 679 lb, the Gravely ZT X 48 KAWASAKI on a typical 6x12 open utility trailer (about 900 lb empty) is roughly 1,579 lb of towed weight. That is within a single-axle 3,500 lb trailer, and your tow vehicle needs to be rated for at least 1,579 lb.
