GENERAL NOTES FOR FIELD OPERATIONS
Before beginning to till, the following instructions should
be noted:
1. Be sure all tiller tines, bolts and nuts are tight.
2. Be certain all guards and shields are in place and
secure.
3. Clear the area to be tilled of rocks, branches and
other foreign objects.
4. Tall grass and weeds should be mowed before tilling.
5. Operate with 540 rpm PTO tractor.
6. Never engage tiller tines with tiller in full raised posi-
tion. Lower tiller to within 3” to 4” off ground, then
engage PTO. Failure to do so can cause damage to
tiller PTO shaft.
7. At first begin tilling at a slow forward speed and shift
up until the desired speed is achieved.
8. Tiller should be operated with the tiller deck level to
the ground.
9. Tiller tines will cut better at a faster rotor speed than
at reduced throttle.
10. Do not engage PTO at full throttle.
11. Tilling should not be done in wet conditions as soil
will stick to tines.
12. After tilling the first 50 feet, stop and check to see
that the tiller is in the ground.
13. Do not make sharp turns or attempt to back up while
tiller is in the ground.
14. Do not engage PTO with machine in the fully raised
or lowered position.
15. Periodically check foreign objects wrapped around
the rotor shaft and remove them after disengaging
PTO, turning off tractor, and removing ignition key.
C A U T I O N !
Do not reverse when tilling. If it is necessary, dis-
engage the PTO drive, lift the implement from the soil
and make sure the area to the rear is clear before
backing.
Never lift the tiller more than 14 inches from the
ground with the PTO engaged or the driveline could
break and cause injury.
C A U T I O N !
Stop tractor and attachment immediately upon
striking an obstruction. Turn off engine, remove key,
inspect and repair any damage before resuming
operation.
The slower the machine advances when tilling, the
more soil will be crumbled.
Always raise the tiller from the ground when turning and
when reversing.
The rotary tiller is not generally suitable for work on
stony soil. A few small stones are usually acceptable and
will create no difficulties.
Working on excessively stony soils can damage the
blades and the machine itself. Such use voids the
warranty.
Small stones are from 1.5 inch to 2.2 inch diameter.
Larger stones must be removed to prevent the tiller from
being damaged.
TILLER HITCH SIDESHIFT
On the T25 Models, the 3-point hitch and the gearbox
can be side shifted to the left of center for various work-
ing conditions.
Loosen the bolts holding the hitch/gearbox frame to the
main frame of the tiller. Slide to left (up to 11 1 / 2 inches)
until desired side shift is obtained, then tighten all bolts.
On the T40 and T55 Models, only the lower hitch pull
brackets may be moved (up to 7 1 / 2 inches) from center
(left or right).
Loosen the bolts clamping each pull bracket and slide
to the desired offset position. Remember, Category I
lower hitch spacing should be 26 inches inside.
Retighten all bolts.
NOTE: Make sure the PTO driveline is not angled more
than 15˚ (see Figure 5). PTO driveline operation with
more than 15˚ side angle will cause excessive wear on
the driveline.
M A I N T E N A N C E
EVERY 8 HOURS SERVICE
• Grease the right hand support of the rotor.
• Grease the “U” joints of the PTO driveline.
• Check the bolts that connect the blades to the rotor.
EVERY 50 HOURS SERVICE
• Change the first oil fill in the gearbox and chaincase
after the first 50 hours service. Following this, the oil
should be changed after every 250 hours service.
• Check blades for wear. Replace if necessary.
• Disconnect, disassemble, and clean the PTO drive-
line. Cover the sliding parts with grease before re-
assembly.
• Check that all bolts and nuts are tight.
• Check level of lubricant in gearbox and chaincase.
Add proper lubricant if required.
NOTE: Oil level must be checked with tiller on flat
surface. Check tension of transmission chain.
EVERY 250 HOURS SERVICE
• Change oil in the gearbox and chaincase.
NOTE: Spilled oil should not be allowed to pollute the
environment. Place a suitable receptacle under the
machine in order to collect the oil and then consign this
to a company authorized to dispose of such products.
The tension of the side transmission chain will need to
be periodically checked. Proceed as follows:
• Remove the PTO driveline from the tractor and the
input shaft of the tiller gearbox. The rotor assembly
must turn free.
• Slacken off lock nut of chain tension idler bolt a few
turns.
• Tighten idler bolt by hand as far as possible, mean-
while using the other hand or a foot to turn tiller rotor.
The tiller should be disconnected from the tractor before
maintenance service is performed. If work is required
while the tiller is attached to the tractor, the tiller must be
blocked securely. NEVER trust the tractors’ hydraulic
system.
If the machine is used in heavy duty conditions, the
maintenance operations must be carried out more
frequently.
Thoroughly clean the grease zerks and around oil fill
plugs before servicing. Dirt mixed with lubricant will
rapidly wear parts and destroy gears and bearings. Keep
it clean.
O P E R ATING INSTRUCTIONS (continued)
W A R N I N G !
Before servicing the machine, disengage the PTO,
engage the parking brake or place the transmission
in “Park,” shut off the tractor and remove the key.
Keep clear of rotating parts; stay on tractor seat
until all motion has stopped.
Do not get under machine to make measurements
or adjustments without securely blocking implement
first.
A T T E N T I O N !
Store the lubricant in a sheltered place, well away
from childrens’ reach.
Always read the recommendations given on the
lubricant containers.
Prevent the lubricants from being splashed on
the skin. Wash the effected part with water if this
occurs.
Old lubricants must be handed over to authorized
disposal companies in compliance with the anti-
pollution provisions locally in force.
