First self-propelled rolls out
KRONE goes self-propelled with what it claims is the worlds first purpose-built, self-propelled mower.
Aptly named the Big M, the German firms monster mower is powered by a 260hp engine through a hydrostatic transmission to four equal-sized wheels.
John Deere supplies the motor and modified cab but there the link ends. Transmission, skid unit design and mowing equipment are all either built by Krone or to its specification.
Cutting gear comprises three front-/side-mounted mowers, adding up to a total working width of 9m (29ft 6in). In theory, at an operating speed of 6mph, that should give a work rate of about 8ha/hour (20 acres/hour).
UK farmers and contractors will get their first chance to see the Big M next year. Krone will trial the machine in 1977 before making it commercially available the following season. *
Monster munch… Krones Big M mower is the firms first move into the prestigious self-propelled sector. Total cutting width is about 9m.
