Length of the power take-off
The drive shaft for the power take-off is supplied together with
the machine. As a consequence of the various three-point
linkages that are currently available, the drive shaft may be too
long for most machines or too short for other machines. It is
extremely important that the drive shaft can slide in and out
freely and does not touch the ground in the work range. If the
drive shaft touches the ground, the bearings of both the
machine and the power take-off of the tractor will be
overloaded and break in the short term.
Follow this procedure to determine the correct length of the
drive shaft:
1.
Make sure the working area is free from bystanders.
2.
Fasten the wood chipper to the tractor but do not yet
fasten the drive shaft.
3.
Lift the machine until the feed shaft is at the same height
as the power take-off of the tractor.
4.
Measure the distance between the coupling grooves on
the power take-off of the tractor and the feed shaft of the machine.
5.
Measure the same length on the pressed in drive shaft.
6.
If the length of the pressed-in drive shaft exceeds the
length of the machine, the drive shaft must be shortened.
Follow this procedure to shorten the drive shaft:
1.
Subtract the length of machine "A" from the length of
drive shaft that has not been cut off "B" or (B-A). This
length determines how much of the shaft must be cut off.
2.
To prevent the shaft from touching the floor, you must
add 25 mm from the length to be cut off. This is how you
determine the final length to be cut off (C).
3.
Use a hacksaw to cut off length (C) from both ends. Cut off
both the plastic tubes and the metal cores.
4.
Use a file to remove the burrs from the sawed edges.
5.
Install the 2 ends of the shaft.
6.
Make sure the shaft can slide in and out freely. If this is not
the case, you must loosen the 2 parts and check for burrs
or chips on the shaft ends. Make sure the shaft can slide
in and out freely before installing it.
