What the specs work out to

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

Mowing time

  • ¼ acre4 min 3 min
  • ½ acre7 min 5 min
  • 1 acre15 min 10 min
  • 2 acres29 min 20 min
  • 5 acres1 h 13 min 51 min
  • 10 acres2 h 26 min 1 h 42 min

About 15 min per acre at 4.11 acres/hour, mowing at 7.7 mph. The second figure is at the published 11.0 mph top speed (5.87 acres/hour) — faster than anyone really mows. About 57.5 acres per tank.

Weight & hauling

  • Machine weight1,780 lb
  • + 6×12 trailer900 lb
  • Towed weight2,680 lb
  • single-axle 3,500 lbCarries it, 820 lb spare
  • tandem-axle 7,000 lbCarries it, 4,320 lb spare

Needs a single-axle 3,500 lb trailer and a vehicle rated to tow at least 2,680 lb.

Gate & trailer fit

  • 32 in gateToo wide
  • 36 in gateToo wide
  • 48 in gateToo wide

Needs at least 72 in of clearance (estimated).

Power & run time

  • Power per deck inch0.583 hp/in
  • Run time per tank~14.0 h

Mowing times assume 4.11 acres/hour: deck width x 7.7 mph at 80% efficiency, which allows for overlap, turns and trimming. 7.7 mph is 70% of the 11.0 mph top speed Altoz publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 11.0 mph, shown so you can see it.

Fit uses the deck width plus 6 in for the discharge chute, because Altoz 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 Altoz'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 Altoz TRX 766 i?

At 1,780 lb, the Altoz TRX 766 i on a typical 6x12 open utility trailer (about 900 lb empty) is roughly 2,680 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 2,680 lb.
