any leaks.
3. Connect the short hydraulic hose—76 cm (2-1/2
ft) to the hydraulic top link port that is closest to
the traction unit (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 traction unit.
6. Start the engine of the traction unit and operate
the spool valve to check the extend and retract
motion of the hydraulic top link.
Note:
If the lifting and lowering the aerator does
not agree with the traction unit control operation,
reverse the hose connections at the traction unit.
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
