OPERATION AND MAINTENANCE
TABLE OF CONTENTS
Tractor Preparation
The 2512 Series Rigid and The Folding In-Row Rippers
up to and thru the 2512F-9 can be used on tractors with
CAT IVN hitches. For rippers larger than the 2512F-9 it is
recommended to be mounted on a caddy. All 2512 and
2512F rippers can be mounted onto a caddy.Before
attaching the In-Row Ripper, prepare the tractor as
follows:
a. The rear tractor tires should be inflated equally
and ballast added according to the tractor
operator’s manual.
b. For mounted type models, install front end
weights as needed on tractor to maintain
stability.
In-Row Ripper Operation
1. Before operating the In-Row Ripper, inspect it to be
sure it is in good operating condition.
2. Replace badly worn or missing parts.
3. While the machine is new, bolt tightness should be
checked after a few hours of operation. Tighten any
loose nuts or cap screws. Check the gauge wheel lug
bolts daily.
4. Check the gauge wheel tire inflation. All tires should
be equally inflated to avoid side draft.
Hydraulic Accumulator
Operation
The 2512 Rigid and Folding In-Row Ripper may be
equipped with the Hydraulic Reset Option. The Hydraulic
Reset Option utilizes a factory-charge accumulator. The
accumulator needs to carry an additional hydraulic
charge to do field work.
The hydraulic charge needs to be greater in magnitude
than the nitrogen pre-charge to create an oil reserve
within the accumulator to maintain working pressure in
the event of a small loss of oil from the system or a
change in ambient temperature.
The ripper does not need to be connected to the tractor
during field operation but connecting the lines to the
tractor will keep them out of harms way.
The ball valve between the pressure reduction valve
manifold and the machine system needs the be turned
“OFF” during field operation. The ball valve should only
be opened to 1.) check the system operating pressure
present, and 2.) adjust the system pressure if it is too
high or too low (below 2,000 psi).
The pressure reduction valve is pre-set at the factory to
have a hydraulic output of 2,000 psi. The pressure
reduction valve will increase the hydraulic pressure of the
system to 2,000 psi if it is less than 2,000 psi and will
allow oil to pass back to the tractor if the system pressure
is higher than 2,000 psi thereby reducing the system
pressure. The pressure gauge will not monitor the
system pressure unless the ball valve is opened, but the
valve should remain in the “OFF” position unless the
operating pressure is being checked or adjusted.
To Charge The Accumulator:
1. Connect the pressure and return lines to the
pressure reduction valve manifold to the tractor.
2. Activate the tractor circuit connected to the pressure
reduction manifold. If the pressure immediately
reaches 3,000psi the connections needs to be
reversed.
3. Open the ball valve on the 2512 (align with the
hydraulic lines entering and leaving the valve
manifold). Monitor the pressure gauge on the
pressure reduction valve manifold and
CLOSE the
valve when the pressure reaches 2,000psi
4. Once the accumulator is charged to 2,000psi there
should be no need to recharge the system except for
ambient temperature changes or leaks in the system.
NOTE
If the system continuously loses pressure, contact
Landoll Corporation and request to speak with a
technician.

DANGER
Do not discharge or attempt to discharge the
accumulator. Do not adjust or remove any fittings
on the accumulator. Failure to heed or comply to
this warning will result in serious injury or death.
