Daily maintenance
When you finish each day of operation carry out the following maintenance:
check all visible parts and components and their connections; tighten all loose bolts and nuts
and replace all damaged and/or worn parts with new genuine ones,
clean the mower, especially between discs and cutterbar, because grass with mud may damage
bearings in disc module,
remove grass and mud,
check the cutterbar,
grease PTO shaft tubes with STP grease,
if necessary, lubricate the parts and components according to lubrication instructions (chapter7).
Parts which may cause risk to operator’s health and safety are as follows: damaged discs,
missing or damaged safety covers, worn or damaged hydraulic hoses, PTO shaft guides, worn
knives and knife holder pins.

After-season maintenance and storing of machine
It is recommended for the operator to wear protective gloves when performing
maintenance works.
At the end of mowing season the following shall be performed:
lower the mower’s cutterbar onto the ground,
take the PTO shaft extension out of the tractor rpm or dismount the complete PTO shaft and
install it into corresponding holder at the 3-point linkage frame,
unmount hydraulic and electrical hoses from the tractor and hang them onto corresponding
holders on the 3-point linkage frame,
unmount the mower from the tractor (reverse procedure as in case of attaching the mower to
the tractor item 5.1), and then drive the tractor away.
Mower should be stored in standstill position, so it is supported onto supporting leg and the
cutterbar. It is recommended to store the set on paved ground, preferably in roofed places,
inaccessible to unauthorized personnel or animals.
If the machine is stored for a long period of time before first operation, its technical condition
should be examined and special attention should be paid to the hydraulics and the drive. Paint the
area where the paint is missing, hydraulic hoses checked and lubricated.
Additionally:
remove any traces of rust and paint the area,
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 cause breakdowns,
periodically inspect the mower and lubricate moving parts in order to protect them from
corrosion which adversely affects the proper operation of the mower,
check hydraulic hoses regularly. Replace any damaged or old hoses. In any case, you should
replace hoses that have been in use more than 5 years from the date of their manufacture printed
on the hose.
