Description
The optional 1.5m cutter bar is a robust construction of double fingers and
reciprocating knife, suitable for cutting shrubs and hedges of a woody material up to
30mm diameter.
Operation
Run the PTO at low speed 150/200 rpm only; normal 540 rpm will cause
unnecessary wear and vibration, which may lead to premature failure. Position the
arm and knife into the work and select a suitable forward speed, which allows the
blade to cut all material without blocking. When trimming material towards the limit of
the cutter bar avoid making arm movements and reduce your forward speed to allow
the knife to time to clear.
Maintenance
•
Grease motor body (5 pumps every 50 hours)
•
Grease knife drive (1 pump every 50 hours)
•
Check tightness and security of all nuts and bolts
•
Sharpen or replace worn or damaged blades and fingers
