End of season maintenance
After the end of mowing season the mower should be carefully cleaned and washed and after
drying all working surfaces and suspension pins should be protected from rust by lubricating with
grease.
Additionally:
touch up any chips in the paint,
check the oil level in the angle drives and the cutterbar (Section 7). If leaks are discovered they
should be repaired immediately and lost oil replaced. If water in oil is discovered immediately
change the oil as it could cause corrosion of internal mechanisms such as gear wheels, bearings,
or shafts, and in effect be the cause of breakdowns,
periodically inspect the mower and lubricate moving parts in order to protect them from
corrosion which effects proper operation of the mower,
check hydraulic hoses regularly. Replace any damaged or old hoses. The period of hydraulic
hose utilization should not exceed 5 years from the date of their manufacture printed on
the hose.

when the cutterbar is leveled should reach from 5 - 7 mm from the bottom. The necessary amount
of oil is shown in the following table.
