If the object does not dislodge using this method and
the tines continue to not spin:
•
Shut off the PTO immediately, shift the tine
direction lever to neutral (N), raise the tiller to its
highest position, and turn the tractor engine off.
•
Lift the roller to its highest position to create easier
access to the tines. Raise the rear deflector, if
necessary, and locate the object that is binding the
tines.
•
Using a broom handle or heavy stick, dislodge the
object from between the tines and the housing. If it
is necessary to reach into the tine area with your
hand to remove an object, use caution around the
tines which may be sharp.
WARNING:
Tiller tines are sharp and can
cause serious injury. Wear heavy gloves and
use extra caution when servicing the tines.
SECTION 10: MAINTENANCE
WARNING:
Before performing any
adjustments, be certain that the tractor’s
engine is not running and the parking brake
is set. If working on the tines, raise the tiller
to its highest point and place blocks under
the edges of the tiller frame to prevent it from
dropping.
Cleaning
It is important after every use to clean the tiller,
especially around the tines. It is much easier to clean
the dirt off of the tiller while it is fresh than if it is left to
dry for a sustained period.
The area around the tines is the most important to clean
for this is the area that receives actual contact with the
ground. Using a garden hose in this area as well as on
the top of the tiller is acceptable, but it is important not
to use direct water pressure on the electric lift cylinder.
After washing the underside of the tiller, start the tiller
tines in motion for a couple minutes to help disperse
any water that may lie in the bearings and tine shaft
areas causing excessive corrosion.
Also, avoid direct water contact with the tank cap on top
of the hydraulic reservoir. Wipe this area clean with a
dry rag to avoid possible contamination while checking
the hydraulic fluid.
It is recommended also that the machine be dried off
after washing, if possible. Water that sits on a machine
can cause corrosion over time. An air hose that is
attached to an air compressor is ideal for drying
machinery such as this. If that is not available, a towel
will suffice. Doing this will help prolong the life and
appearance of the tiller.
Lubrication
There are several lubrication points on the tiller
attachment. Using a lithium based lubricant, white
lithium spray lube is recommended, contact all the pivot
points where the tiller pivots when raising and lowering.
These are where the sleeve hitch, the attachment hitch,
and the electric lift cylinder contact the tiller frame.
The attaching clips and the point where they pass
through their pins should also be lubricated. This
should be done every 10 running hours on the tiller to
prevent corrosion and maintain free movement.
The roller needs to be lubricated in several areas. On
each end of the roller shaft that runs through the middle
of the roller is a bearing. Each bearing has a grease
fitting with a removable cap that will require a standard
grease gun to lubricate every 25 running hours. Be
certain to replace the grease fitting cap after lubricating
to prevent contamination.
Also on the roller, use white lithium spray grease on the
spring loaded locking rod where it passes through the
adjustment bar, and where the compression spring is
on the long side of the locking rod. Just above the
locking rod is a clevis pin surrounded by two springs,
lubricate this area also. This spring loaded section
allows the roller to fluctuate and follow uneven ground.
The point where the roller frame attaches to the tiller
frame is a pivot point. The two attaching bolts, where
the roller assembly pivots, need lubrication also.
Changing Hydraulic Filter and Fluid
WARNING:
Hydraulic hoses, fittings, and
fluid become hot during normal usage. Allow
the machine and its related hardware to cool
down before checking the fluid level or
performing maintenance.
Hydraulic Filter
The hydraulic filter should be changed every 50 running
hours on the tiller. To change the filter:
•
Place a pan (shorter than 1.5”) under the oil filter to
collect the oil that remains in filter when not using.
•
Use a filter wrench to loosen the filter. Drain excess
oil into the pan.
•
Install a new filter, part #723-0405, by first
moistening the o-ring on the new filter with
hydraulic oil. Tighten the filter until the o-ring makes
contact with the filter base, then tighten 1/4 turn.
