What the specs work out to
Figures MowerFacts computes from Kubota’s own numbers — not published by the manufacturer.
Gate & trailer fit
- 32 in gateFits
- 36 in gateFits
- 48 in gateFits
Needs at least 27 in of clearance (estimated).
Power & run time
- Power per deck inch0.206 hp/in
- Run time per tank~0.5 h
Fit uses the deck width plus 6 in for the discharge chute, because Kubota 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.
