What the specs work out to
Figures MowerFacts computes from Worx’s own numbers — not published by the manufacturer.
Gate & trailer fit
- 32 in gateFits
- 36 in gateFits
- 48 in gateFits
Needs at least 26 in of clearance (estimated).
Power & run time
- Battery energy200 Wh
Fit uses the deck width plus 6 in for the discharge chute, because Worx doesn't publish an overall width — measure before buying if a gate is tight.
Battery energy is voltage x amp-hours; run time depends on cut height, grass load and blade speed, so it isn't estimated here.
