OPERATION AND MAINTENANCE
Tractor Preparation
The Landoll 2132 Coulter Chisel is designed to be pulled
by tractor equipped with a double lip or clevis type hitch.
If your tractor is not equipped as such, you need to
purchase the hitch from your local tractor dealer.
Before attaching the Coulter Chisel, prepare the tractor
as follows:
1. Inflate the rear tractor tires equally and add ballast
according to the tractor operator's manual.
2. Lock the tractor drawbar in the center position.
Coulter Chisel Preparation
1. Prior to operating the 2132 Coulter Chisel, inspect it
thoroughly for good operating condition.
2. Replace worn or missing parts.
3. When the machine is new, check the bolt tightness
after a few hours of operation. Tighten any loose nuts
or bolts. Check the lift wheel lug bolts daily.
4. Check the lift wheel tire inflation. Inflate all tires
equally to avoid side draft. Follow the tire
manufacturer's recommended pressures listed on the
sidewall of the tires.
5. Lubricate the machine as shown in
Maintenance" on page 4-13
Table" on page
4-13.
Attaching to the Tractor
1. Align the tractor drawbar with the machine. Raise or
lower the Coulter Chisel ring hitch, as needed, using
the swivel jack. Attach the unit with proper size hitch
pin.
2. Always place the swivel jack on the interior mount
before setting the machine in motion.
3. Clean all hydraulic couplings and attach to the
tractor.
4. Fully extend the hydraulic lift wheel cylinders, and
place the cylinder lockouts in the transport lock
position over the cylinder rods. Secure the lockouts
with the lockout pins.

Hydraulic Lift System
Th Coulter Chisel is equipped with a rephasing hydraulic
lift system to raise and lower the unit in the field.
Figure 4-1: Hydraulic Leak Detection
Escaping hydraulic fluid can cause serious
personnel injury. Relieve system pressure before
repairing, adjusting, or disconnecting. wear
proper hand and eye protection when searching
for leaks. Use cardboard instead of hands
Figure
4-1. Keep all components (cylinders,
hoses, fittings, etc.) in good repair.
1. The rephasing hydraulic lift system contains smaller
wing frame cylinders plumbed in series with larger
center frame cylinders. It is important that the
cylinders be connected in the proper series for the lift
system to operate correctly. When the cylinders are
fully extended and held in this position, oil is able to
flow through the cylinders (or rephase) and allow the
cylinders to operate in sync. This also allows the
system to purge any air that may enter the system
without having to loosen or crack hydraulic lines.
2. The hydraulic system is not filled with oil and should
be purged of air before transporting and field
operations. Carefully hitch the Coulter Chisel to the
tractor and connect the hydraulic lift hoses. Check to
make sure the tractor hydraulic reservoir is full of the
manufacturer's recommended oil. Slowly raise the
machine, and continue to hold the hydraulic lever
until all lift cylinders are fully extended. With all
cylinders fully extended remove the 2 X 16 transport
lockouts
See Figure
shown
See Figure
4-3. Lower and raise the unit to
verify that all cylinders are working simultaneously
throughout the stroke. If the cylinders are not working
evenly or together, fully extend the lift cylinders and
continue to hold the lever to purge any remaining air.
Do not loosen any hoses or fittings. Recheck tractor
reservoir to make sure it is within operating limits.
