Hydraulic Maintenance
1. Check the tractor hydraulic fluid level per tractor
owner's manual and after any leakage. Check fluid
level with the cylinders in the retracted position.
2. If a cylinder or valve leaks, disassemble the parts to
determine the cause of the leak. Any time a 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
Landoll dealer.
3. Check all hydraulic hoses weekly. Look for binding or
cracking. Replace all worn or defective parts
immediately.
IMPORTANT
Lower the unit to the ground, and relieve hydraulic
pressure before attempting to service any hydraulic
component.
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. 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.

on how to purge the hydraulic systems.
Hose Identification
1. The hydraulic hoses are color coded to help identify
and match the attaching hoses on the Grain Drill. An
identification decal is placed on the front of the hitch
to help identify the hoses
2. For the Grain Drill, hoses will be identified as follows:
Blue - Lift Wheels
Black - Auxiliary (Optional Row Markers)

Parking
1. When unhitching the grain drill from the tractor, park
the drill on a level area to prevent rolling and shifting.
The Grain Drill has negative hitch weight and will need
to lowered to the ground for parking. Any seed left in
the drill will increase the negative hitch weight. It is
best to park the drill without any seed left in the box.
WARNING
The Grain Drill has negative tongue weight. Use a
properly sized locking style hitch pin for the
tractor drawbar and drill hitch. Stand clear of
hitch when pinning/unpinning the drill hitch.
1. To park the drill:
a.Fully raise the drill extending the main lift cylinders
b.Remove the transport locks from the cylinder shafts
and place in the storage location

page 4-3.
c.Remove the parking stands from transport position
See Figure 5-3
and install the parking stands in
