What the specs work out to
Figures MowerFacts computes from Kress’s own numbers — not published by the manufacturer.
Coverage & ground
- Rated work area24,281 m²
- In acres6.0 ac
- In square feet261,359 ft²
- Max slope40% (22°)
Gate & trailer fit
- 32 in gateFits

- 48 in gateFits
Needs at least 20 in of clearance (estimated).
Power & run time
- Battery energy200 Wh
Fit uses the deck width plus 6 in for the discharge chute, because Kress doesn't publish an overall width — measure before buying if a gate is tight.
Work area is Kress's own rated maximum, converted from the 24,281 m² they publish. A robot rated below your lawn will not keep up with it.
Maximum slope is 40%, which is about 22°. Makers quote one or the other; they are the same figure, and 40% is not 40°.
Battery energy is voltage x amp-hours; run time depends on cut height, grass load and blade speed, so it isn't estimated here.
