What the specs work out to

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

Gate & trailer fit

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

Needs at least 67 in of clearance (estimated).

Power & run time

  • Run time per tank~13.5 h

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