What the specs work out to

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

Mowing time

  • ¼ acre6 min 4 min
  • ½ acre13 min 9 min
  • 1 acre25 min 18 min
  • 2 acres51 min 36 min
  • 5 acres2 h 7 min 1 h 29 min
  • 10 acres4 h 15 min 2 h 58 min

About 25 min per acre at 2.35 acres/hour, mowing at 5.6 mph. The second figure is at the published 8.0 mph top speed (3.36 acres/hour) — faster than anyone really mows. About 12.0 acres per tank.

Weight & hauling

  • Machine weight816 lb
  • + 6×12 trailer900 lb
  • Towed weight1,716 lb
  • single-axle 3,500 lbCarries it, 1,784 lb spare
  • tandem-axle 7,000 lbCarries it, 5,284 lb spare

Needs a single-axle 3,500 lb trailer and a vehicle rated to tow at least 1,716 lb.

Gate & trailer fit

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

Needs at least 59 in of clearance (estimated).

Power & run time

  • Power per deck inch0.442 hp/in
  • Run time per tank~5.1 h

Mowing times assume 2.35 acres/hour: deck width x 5.6 mph at 80% efficiency, which allows for overlap, turns and trimming. 5.6 mph is 70% of the 8.0 mph top speed Ariens publishes - almost nobody mows flat out. The "at top speed" figure is the same sum at 8.0 mph, shown so you can see it.

Fit uses the deck width plus 6 in for the discharge chute, because Ariens 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 Ariens'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.

Ariens APEX 52 KAWASAKI questions

What size deck is on the Ariens APEX 52 KAWASAKI?

The Ariens APEX 52 KAWASAKI has a 52-inch (1321 mm) cutting deck with 3 blades.

What engine is in the Ariens APEX 52 KAWASAKI?

How much does the Ariens APEX 52 KAWASAKI weigh?

The Ariens APEX 52 KAWASAKI weighs 816 lb (370.1 kg) as specified by Ariens.

What size trailer do I need for the Ariens APEX 52 KAWASAKI?

At 816 lb, the Ariens APEX 52 KAWASAKI on a typical 6x12 open utility trailer (about 900 lb empty) is roughly 1,716 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 1,716 lb. Tongue weight, axle placement and your own trailer's empty weight still have to be checked — this is the arithmetic, not a loading plan.

About 18 min per acre, from its 52-inch deck at 8 mph and 80% efficiency — roughly 3.36 acres an hour, so five acres is about 1 h 29 min. Rough or obstacle-heavy ground takes longer; this is deck width times ground speed, not a timed test.
