OPERATION AND MAINTENANCE

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, before disassembling the
part, contact Landoll service at 785-562-4721 for
further direction. 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
Unfold, 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
(See Figure 4-22.) This
will require activating the fold circuit to engage 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.
See “Hydraulic Lift System” on
page 4-3 and “Hydraulic Fold System” on
page 4-5
on how to purge the hydraulic systems.

Transport
1. Check and follow all federal, state, and local
requirements before transporting the Disc.
2. The 6250 should be transported only by tractor
required for field operation. The implement weight
should not exceed more than 1.5 times the tractor
weight.
Refer to “Standard Specifications” on
page 2-1 for estimated weight of each model.
Maximum transport speed for the 6250 is 20 mph for
the implement and is designated on the speed
identification symbol located on the front of the
implement
(See Figure 4-23.)

CAUTION
3. When towing equipment in combination, the
maximum equipment ground speed shall be limited
to the lowest specified ground speed of any of the
towed implements.
4. Maximum transport speed shall be the lesser of
travel speed specified in the operator's manual,
speed identification symbol, information sign of
towed equipment, or limit of road conditions.
5. Slow down when driving on rough roads. Reduce
speed when turning, or on curves and slopes to
avoid tipping. Equipment altered other than the place
of manufacture may reduce the maximum transport
speed. Additional weight, added tanks, harrowing
attachments, etc. may reduce implement load
carrying capabilities.
1. Excessive speed may result in loss of control
of the tractor and implement, reduced braking
ability, or failure of the implement tire or
structure. Do not exceed the implement
maximum specified ground speed regardless
of the capability of the maximum tractor
speed.
2. Due to the weight of this machine, check local
bridge capacities before crossing.
Approximate weights for each model are
listed in the front of this manual (See
“Standard Specifications” on page 2-1.)
