Before fitting the PTO for the first time, it
may be necessary to adjust the length.
There should be maximum engagement of
the sliding tubes without bottoming at the
shortest operation position. To check, first
connect the mower to the tractor. Pull the
PTO shaft apart and connect to the tractor
3. Carefully deburr the ends of the tubes with a
file and remove any chippings from the tubes
4. Shorten shield tubes one at a time by cutting
the same length that was cut from the drive
tubes. If the driveline is equipped with Single
Chain Restraint System, shortening the
driveline will involve removal of the plastic
ring which connects the shield tubes. If it is
necessary to remove this collar, ADD A
RETAINING CHAIN TO THE TRACTOR
SIDE OF THE DRIVELINE SHIELD.
5. Grease the internal drive tube. Reassemble
the shield on the driveshaft.
ATTENTION: SFT drivelines with 4-tooth
profiles must be reinstalled in such a way that
the grease fittings on the cross kit bearings
are aligned.
6. Check the length of the driveshaft at the
minimum and maximum positions of the
machine. Telescoping tubes must always
overlap by at least a ½ of their length. During
manoeuvres, when the driveline is not
rotating, the telescopic tubes must have a
suitable overlap to maintain the tubes aligned
and allow them to slide properly.
