Hydraulic Maintenance
IMPORTANT
Lower the Drawbar Seeder to the ground, and relieve
hydraulic pressure before attempting to service any
hydraulic component.
Escaping fluid under pressure can be nearly
invisible and have enough force to penetrate the
skin causing serious injury. Use a piece of
cardboard, rather than hands to search for
suspected leaks. Wear protective gloves and
safety glasses or goggles when working with
Hydraulic System
1. Check the tractor hydraulic fluid level per Tractor
owner's manual and after any leakage. Check fluid
level with the Hydraulic Cylinders in the extended
position.
2. If a Hydraulic Cylinder leaks, disassemble the parts
to determine the cause of the leak. Any time a
Hydraulic Cylinder is opened up, or whenever any
Seal replacement is necessary, it is advisable to
clean all parts and replace all Seals. Seal Kits are
available from your Brillion dealer.
3. Check all Hydraulic Hoses weekly. Look for binding
or cracking. Replace all worn or defective parts
immediately.
4. Transport Locks are provided to hold the implement
in a raised position. Do not attempt to perform any
service work under the implement without first
installing the Transport Locks. See Figure 3-5.
Before servicing any hydraulic component, lower the
implement to the ground and relieve all system
pressure. If a hydraulic component is disconnected,
repaired, or replaced, it will be necessary to purge
the system of air before operation. See "Hydraulic
Lift System" on Page 3-7.
Front and Rear Roller
Adjustment
IMPORTANT
To maximize seed germination, peaks on Rear Roller
Wheels should line up with valleys on the Front
Roller Wheels. This will require adjusting the Clamp
Bands on each end of the Rear Roller Drum and
moving the Wheels until valleys and peaks line up.

WARNING
NOTE
Failure to position the Clamp Band Socket Head Bolt
(Clamp Band open section) over the Roller Drum weld
seam will cause Clamp Band to loosen and slide.
After an initial run of 5-10 hours, check the Front and
Rear Roller Assemblies to ensure that the Wheels are
tight to one another and that the Clamp Bands are tight. If
not slide the Roller Wheels tight together and adjust the
Roller Clamp Bands per Roller Adjustment Procedure.
Tighten the Clamp Band Socket Head Bolt (Clamp Band
open section) over Roller Drum weld seam to 75 Ft-Lbs.
Thereafter check Front and Rear Roller Assemblies
every 50-100 hours.
Roller Adjustment Procedure
1. Adjust the Front Roller Wheels first. Loosen Clamp
Bands and slide the Roller Wheels snug against
each other, centering the entire assembly under the
Deflector.
2. Position the Clamp Band Socket Head Bolt (Clamp
Band open section) over the weld seam on the Roller
Drum. See Figure 4-3.
3. Slide the Clamp Band against the End Wheel on
each end of the Roller and tighten the Clamp Band
Bolt to 75 Ft-Lbs.
4. Adjust the Rear Roller Wheels in the same manner as
you adjusted the Front Roller Wheels except, start at
the center of the Rear Roller and align the peaks of
the Rear Roller Wheels with the valleys of the Front
Roller Wheels. This will provide the best alignment of
worn Roller Wheels and maximize seed germination.
