Gearboxes
Before first use check gearbox oil level, thereafter check every 8 hours.
After the first 50 hours drain and replace the gearbox oil,
thereafter, annually. Replace with EP90.
Regularly inspect gearbox seals. If oil is leaking replace immediately.
It is your responsibility to maintain a long and reliable working life.
Check that gearbox bolts are fully tightened (85 Nm Max).
Flail Rotor & Roller (Daily)
Grease all bearings daily, at least every 8 hours and especially after washing.
10-30 pumps of grease may be required to flush any contamination from the
bearings.
Check there is no wrapping of string, plastic, grass or other debris on rotor
shaft and rear roller.
Check the condition of flails and ensure all retaining bolts are tight. When
flails are replaced, care must be taken to maintain balance of the rotor shaft,
do not change to a different type.
Never operate with any flails missing. This will cause severe vibration and
lead to rapid bearing wear and quickly cause the hood to crack.
Warning
Check that all gearbox fixing bolts are tight. When the machine is new there
will will be a ‘bedding in’ period when very frequent checking is important.
Warning
It is imperative the grub screws are checked on the bearing and pulley taper
locks (once bedded in, loctite glue may prove useful).
Warning
Never carry out any servicing or maintenance work without first disengaging
the PTO and stopping the tractor.
