What the specs work out to

Figures MowerFacts computes from Toro’s own numbers — not published by the manufacturer.

Mowing time

  • ¼ acre3 min 2 min
  • ½ acre6 min 4 min
  • 1 acre12 min 9 min
  • 2 acres25 min 17 min
  • 5 acres1 h 1 min 43 min
  • 10 acres2 h 3 min 1 h 26 min

About 12 min per acre at 4.88 acres/hour, mowing at 8.4 mph. The second figure is at the published 12.0 mph top speed (6.98 acres/hour) — faster than anyone really mows. About 48.8 acres per tank.

Weight & hauling

  • Machine weight1,448 lb
  • + 6×12 trailer900 lb
  • Towed weight2,348 lb
  • single-axle 3,500 lbCarries it, 1,152 lb spare
  • tandem-axle 7,000 lbCarries it, 4,652 lb spare

Needs a single-axle 3,500 lb trailer and a vehicle rated to tow at least 2,348 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 inch0.486 hp/in
  • Run time per tank~10.0 h

Mowing times assume 4.88 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 Toro 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 Toro 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 Toro'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.
