prevent any leaks.
3. Connect the 76 cm (2-1/2 foot) long hydraulic
hose to the hydraulic top link port which is closest
to the tractor (Figure
sealing tape or compound to the hose threads to
prevent any leaks.
4. Install quick couplings to the hydraulic hoses
(1/2-14 NPTF hose end thread size). Apply
pipe-thread sealing tape or compound to the
hose threads to prevent any leaks.
5. Connect the 2 hydraulic hose quick couplings to
the ports provided on the tractor.
6. Start the tractor engine and operate the tractor
spool valve to check the extend and retract
motion of the hydraulic top link.
Note:
Reverse the hose connections, at the
tractor, if they do not agree with the tractor
control operation.
7. Secure the rod end of hydraulic top link to the
most forward hole possible in the aerator bracket
with link pin and lynch pin
