110 cm working width

Cuts standing grass and cereal crops, and will take bush up to a couple of centimetres thick. The bar articulates side to side, so it follows ground that is not flat.

Ground covered on one charge

0.38 ha with a second battery — swapped in under a minute, so the second charge costs no more of the day than changing it.

Width times working travel, where the travel comes from the battery’s capacity against one measured run — a 650 mm rotavator over 440 m. Every other tool is scaled from it by width and power draw rather than timed separately, so treat these as the shape of the answer rather than a field result.
