472H Potato Harvester Owner Operator’s Manual
10. Route and connect the hydraulic lines of the harvester
to the tractor. Attach the main control valve and lines to
the tractor. (Check the tractor operator’s manual or ask
your dealer for information on hookup to the tractor’s
hydraulic system.)
11. Mount the electric control box in the tractor cab.
12. Route and connect wiring harness from the harvester to
the electronic control box in the tractor cab.
13. Plug control box power cord into auxiliary power port in
tractor.
14. Start the tractor, activate hydraulic control valve then
operate all control switches to activate each hydraulic
system. Extend each cylinder to its maximum length.
Check the tractor hydraulic reservoir to replenish the
hydraulic oil.
Always place the Lockwood 472H Harvester on a hard, dry
surface that is free of obstacles and debris. When
ATTACH-
ING
the machine to the tractor, follow this procedure.
1.
Clear the area of bystanders, especially small children.
2.
Make sure enough clearance exists from obstacles to
safely backup to the harvester.
3.
Back the tractor up slowly aligning the pintle hitch of
the harvester with the tractor drawbar.
4.
Jack up the hitch to clear the tractor drawbar.
5.
Connect pintle hitch of the harvester to tractor and se-
cure with appropriate hardware.
6.
Check the level across the harvester’s main frame.
7.
Shut off tractor!
8.
Clean and grease the PTO shaft of the tractor and the
implement end of the driveline input connection.
9.
Connect the driveline to the tractor by rotating the lock-
ing collar and simultaneously pushing the driveline onto
the tractor PTO shaft. Properly attach the implement
end of the driveline to the harvester and tighten all bolts
to their specified torque.
IMPORTANT
For maximum efficiency, level the machine during opera-
tion.
WARNING
Heavy tongue weight can cause severe injury or death.
Support the jack and tongue securely. Approximate
tongue weight is 3500 lbs. Refer to tractor manual for
drawbar ratings, and follow tractor manufacturer rec-
ommendations if drawbar needs additional support.
WARNING
Check the length of the telescoping members to insure
the driveline will not bottom out or separate when turning
and/or traveling over rough terrain. Length modification of
the implement input driveline should only be done by the
implement manufacturer!
NOTE
Check shaft articulation and clearance zone! Joint
articulation of more than 70 to 80 degrees leads to
damage. Contact between implement input driveline
and tractor or implement (e.g. three point hitch, drawbar,
hitch pin, jacks, etc.) leads to damage. Do not use
tractors that have a PTO connection point that does not
allow the implement input driveline to articulate fully
without interference.
IMPORTANT
When engaging or disengaging the PTO, place engine
at low idle speed.
