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.
