What the specs work out to

Figures MowerFacts computes from Cox’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).

Fit uses the deck width plus 6 in for the discharge chute, because Cox doesn't publish an overall width — measure before buying if a gate is tight.
