Leaf vacuum hose for hopper (optional equipment)
A Leaf vacuum hose can be purchased and fitted on top of the hopper as an optional equipment.
The hose can be used to collect leaves, hedge cuttings and pine needles, for example.
It can swivel through 360º above the machine (if a roll bar is fitted, it can swivel around up to the roll bar).
