POWEROLL - a power pack upgrade kit for Automower & T.H.White Auto-Rollers (AR3 & AR4)

Designed to replace the original engine, clutch and gearbox with
an easy to install, easy to operate, hydraulic drive unit.

The engine and gearbox fitted to the AR3/4 are fine when working correctly, however the majority of Auto-Rollers are elderly and very expensive to replace with similar components.
Even then, still not user friendly compared to new machinery. The bolt in upgrade kit from Poweroll consists of a new engine and hydraulic drive kit enabling a new lease of life for the old roller. This power pack enables your machine to start easily with a turn of the key, and is much more user friendly for the operator, even more so for the AR4 when the optional upgrade for power steering is selected.
