Prior to Operation Checking the length of the universal drive shaft Before using the mower unit for the first time, the hitch and universal drive shaft must be adjusted to suit the tractor. Caution! The maximum universal drive shaft inclination and quiet running of the mower unit can only be achieved by correct hitching. It will often be necessary to change the length of the universal drive shaft because of the different locations of p.t.o. shaft on the various tractor types. Check the length of the universal drive shaft in all operating positions to avoid prevent crushing or insufficient profile overlap.
LZ
Pull universal drive shaft halves apart. Fit universal drive shaft halves on the tractor and the machine side.
a
Hold universal drive shaft halves alongside each other.
PULZ
Universal drive shaft - shortest operating position
69307
100
LZ = length of universal drive shaft when pushed together PULZ = profile overlap a = 40 mm
LB 1/2
During straight travel, the universal drive shaft halves should engage as far as possible but should not abut at the ends.
1/2
If the universal drive shaft halves abut at the ends, they must be shortened to the required length. There must be a travel distance of a = 40 mm. (Fig. 100)
PULB
Universal drive shaft - longest operating position 69309
101
LB = maximum length of universal drive shaft in operation PULB = profile overlap (Fig. 101) During transport and when the drive is switched off, there must be a profile overlap (PU) of at least 100 mm.
