Hydraulic Safety

• Inspect all hydraulic hoses and fittings for cracks and
abrasions at least once a year. Tighten or replace as
needed.

• Do not over-tighten hydraulic fittings, excessive
torque may cause them to crack.

• Care must be taken to prevent twisting when
tightening hose connections. Straighte n any hose that
appears twisted immediately. A twisted hose can
burst under pressure.

• When connecting the hoses to the cylinders, tubings
or fittings; always use one wrench to prevent the hose
from twisting and another wrench to tighten the union.
Excessive twisting will shorten hose life and loosen
hose fittings.

CAUTION: Hydraulic fluid escaping
under pressure can have enough f orce
to penetrate the skin. Hydraulic fluid
may also infect a minor cut or opening
in the skin. If injured by escaping fluid,
see a doctor at once. Serious infection
or reaction can result if medical
treatment is not given immediately.
Make sure all connections are tight and
that hoses and lines are in good
condition before applying pressure to
the system.

Tractor Preparation

Refer to the operator’s manual furnished with your tractor
for recommended adjustme nts and weight distribution.

Wheels

STEP 1

The use of the proper air pressure is the most important
factor in satisfactory performance and maintenance of
implement tires. Underinflation will damage the cord body
of the tire and cause a series of diagonal breaks in the
fabric in the sidew all area.

If the tire buckles or wrinkles, the air pressure must be
increased to the point where the sidew alls remain smooth
while operating.

NOTE: DO NOT OVERINFLATE TIRES.

Check the air pressure every two or three weeks and do
not allow pressure to drop to a point where buckling or
wrinkling of the tire may be possible.

The recommended tire pressure for each front gauge
wheel is 55 psi (3.7 bar) and the rear lift wheels is 70 psi
(4.8 bar).

It is recommended that all wheel nuts be checked for
tightness after first day of use. Wheel nuts are tightened
to 90 ft-lbs (122 N•m). Check periodically to be sure the
wheel nuts are tight. Paint or rust can work out causing
the wheel to become loose.

NOTE: The down pressure is factory set at 1000 psi.

STEP 4

Hydraulic Basket Operation

With the hydraulic rolling basket, there are several
adjustments to achieve the best residue management.
Depending on field conditions, adjustments can be made
to create an even, level surface finish.

Dry Conditions - During dry f ield conditions, the active
down pressure can be used. The factory setting is at
1000 psi. If more basket crumbling action and residue
pinning is required, increase the down pressure app lied
to the baskets (raise gauge pressure). Be care ful not to
set the pressure too high, or the basket will lift the coil
tines harrows and rear chisels out of the ground.

Normal Field Conditions - During normal field
conditions the active down pressure can be used. The
factory setting (1000 psi) is a good place to start.
Depending on residue and soil surface finish, pressure
can either be lowered or raised to achieve optimal soil
finish. If less soil crumbling and residue pinning is desired
the psi can be reduced.

Wet Field Conditions - During wet field conditions the
float condition may be used. This operation may be
useful when the basket begins to acquire soil. Float will
allow basket to lightly float over the soil while still pinning
residue and breaking up soil clumps without acquiring
soil on the baskets. If the baskets begin to acquire too
much soil, they can be raised to just allow the coil tine
harrow to level the soil and residue.

To put the baskets in FLOAT mode move the control va lv e
lever ( 1) f rom t he h orizo nt al positi on shown to the vertical
(2) position. In FLOAT mode the only down pressure is
the weight of the basket assemblies.

Storage

Preparing The Machine For Storage

Prepare the machine for storage at the end of each
season. When possible, store the machine in a covered
location with the wings lowered. Preventing rust will
lengthen the life and assist in performance.

Procedure

1. Park the implement on a solid, level surface, away
from other machines.

2. Use the tractor hydraulics to lower the wings of the
implement.

3. Clean the implement of any dirt, grease or other
materials.

4. Put a protective layer of heavy oil or grease on all
earth engaging parts to prevent rust.

5. Paint any damaged surfaces, surfaces with paint
removed, or surfaces with rust.

6. Inspect the implement for any loose parts or
hardware.
a) Replace any worn parts.
b) Tighten any loose hardware.

7. Lubricate all components of the implement.

8. Raise the implement and transport to the area where
it is to be kept. The area must be level.

9. Stop the engine, apply the park brake, and take the
key with you.

10. Place boards under the disks and shanks.

IMPORTANT: If boards cannot be placed under
the disks and shanks, place the cylinde r stops on
the main frame lift cylinders. Lower the i mplement
onto the cylinder stops. This will prevent the
disks and shanks from penetrating the ground.

11. Start the engine and lower the implement on the
boards under the shanks.

12. Completely retract the wheel lift cylinders.

13. Use the front hitch jack to support the front hitch of the
implement.

14. Remove the tractor from the implement.

15. Apply grease to the surfaces of the cylinder rods that
are still showing.
