5.13 CHECKING AND REPLACEMENT OF SPREADER UNIT
KNIVES
Spreader unit knives must be regularly checked. Visually inspect the knives and fixing bolts
and check tightening torque of nuts. This inspection is particularly important when spreading
manure which may contain stones or other foreign bodies and after installation of new cutting
knives and after the first start-up of the machine.
Excessively worn or damaged knives and fixing bolts must be replaced with new ones. The
bolts should be mounted with their heads on the outside, when seen from the centre of the
wormshaft. Tighten the nuts of fixing bolts with torque of 90 Nm.
DANGER
During work check source of unnatural vibrations and noises, which may come from the
machine.
Before replacement turn off tractor engine and remove the key from the ignition and engage
tractor parking brake. Ensure that unauthorised persons do not have access to the tractor.
Protect tailgate from falling down by closing the cut-off valve and with a suitable mechanical
support which is durable and stably mounted. Mechanical support should be placed between
tailgate and floor conveyor strip.
ATTENTION
If a knife is lost, vibration may occur, which may cause damage to the wormshaft bearings.
Before securing knives, it is necessary to check the direction of wormshaft rotation. Reverse
setting of knives will cause poor disintegration of material spread.
Parts should always be replaced with original parts.
