Checking the tautness of the chain of the chain drive of the scarifier and rollers
The power of the drive shaft of the scarifier and the rollers is transferred using a chain to
the axles of the rollers. Permanent tautness of the chain is ensured by the tightener which is adjusted
using the tightening bolt N (Fig. 29). Properly tightened chain should give by about 5 mm when
the end of the tightener K is depressed.
Fig. 29. Adjustment of the tautness of the chain drive chain (view with guard removed) of the crop rollers
(for mowers: KT 260 S (H), KT 300 S (H), KT 260 W (H), KT 300 W (H))

Everyday maintenance
The following should be done after everyday operations:
check all visible parts and components and their connections, tighten all loosened nuts or
screws and replace all worn or damaged parts,
wash the mower with water under pressure after every use, especially between the cutterbar and
discs, because dried mud with grass can cause premature wearing out of the bearings in the disc
assembly or block proper rotation of the assembly,
clean any remaining plant matter, dirt or mud,
check the condition of the cutting unit,
lubricate the telescoping shafts of the articulated telescoping shaft with STP grease,
if needed lubricate according to lubricating instructions (Section 7).
Parts, which may cause risk to operator’s health and safety are as follows: damaged disks,
tarpaulin covers, worn or damaged hydraulic hoses.
6.9.4.
Storing of machine
Upon completion of operation 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,
detach hydraulic and electrical hoses out of the tractor and hang them onto corresponding
holders on the 3-point linkage frame,
detach 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.
Detached mower should be stored in standstill position, so it is supported onto supporting leg
and the cutterbar (Fig. 30). It is recommended to store the set on paved ground, preferably in roofed
places, inaccessible to unauthorized personnel or animals.
