6.9.2. Checking the tension of tine and roller conditioners’ driving chain.
Drive from PTO shaft is transmitted by means of driving chain on the conditioner. The tensioner
provides the constant tension of the chain and is regulated by the nut N (Fig. 23).
A deflection of the properly tensioned chain under finger pressure K should be about 5 mm.

Everyday after work please carry out the following maintenance:
check all visible units and parts and their connections; tighten all loose bolts and nuts and replace
all damaged and/or worn parts with new genuine ones,
clean the mower each day after working, especially between discs and the cutterbar, because grass
with mud may damage bearings in the disc module,

check the cutterbar,
grease PTO shaft tubes with STP grease,
if necessary, lubricate the parts and units according to lubrication instructions (chapter 7).
6.9.4. After-season maintenance
At the end of the season the mower should be cleaned, washed and dried. Carefully grease unpainted
surfaces and 3-point linkage pins. After that the following work should be carried out:
Remove any traces of rust and paint the area affected.
Check lubrication of intersecting axis gear and cutterbar. If leaks occur, remove them immediately.
If water is discovered in the oil, it must be changed, otherwise the gears, bearings and shafts could
be damaged.
Periodically check the mower and secure the moving parts with grease to prevent the mower from
rust, which affects the proper functioning of the mower.
Regularly check hydraulic hoses. In case of damage or expiry replace with new ones. Expiry
period should not exceed 5 years.
