ASSEMBLY
Adjust the top link to bring the machine frame into the
vertical position.
Remove leg pins and raise the stand legs to their
stowage position – replace leg pins and secure in
place with 'R' clips.
Adjust check chains to prevent sideways movement
of the tractor's linkage.
Measure the PTO shaft and cut to the dimension
shown below. The finished length of the shaft should
be 75mm (3") less than the measured distance 'A'
between tractor shaft and gearbox stub shaft to allow
for fitting. Refer to PTO installation page.
NOTE: For subsequent use with different tractors,
measure again - there must be a
minimum shaft overlap of 150mm (6").
