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

Gate & trailer fit

32 in gateFits
36 in gateFits

Needs at least 26 in of clearance (estimated).

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