Driving the tractor too fast will make aeration
holes appear less frequently and too shallow
(short plugs) may do a less than desirable job.
Do not engage the PTO with the drive
assembly in the transport position.
STOPPING THE MACHINE
1. Disengage the PTO clutch.
2. Pull the steering levers to the NEUTRAL
position and then move the FSC lever
backward to the NEUTRAL-PARK position.
3. Slow the engine to idle; put the throttle in the
IDLE position.
4. Retract the tines into the transport position
using the lift lever.
4. Turn the ignition switch OFF.
5. Engage the parking brake.
IMPORTANT: The hydrostatic transmissions
lock to prevent the machine from rolling freely
with the engine stopped. However, if the
machine is parked on a slope, it is necessary to
ENGAGE the parking BRAKE to prevent the
machine from creeping. This is due to a small
amount of slippage in the hydrostatic transmis-
sions, especially when transmission fluid is
warm.
LUBRICATION
Grease Fitting and Oil Point Lubrication
Lubricate the grease fittings and oil points after ev-
ery 8 hours of operation (or as recommended be-
low). Use SAE general purpose lithium or
molybdenum base grease for grease fittings and
light machine oil (SAE 10) to lubricate oil points.
Gearbox
The gearbox is permanently lubricated (oil filled) and
sealed requiring no scheduled lubrication. How-
ever, the gearbox oil seal(s) should be checked ev-
ery 25 hours for indication of an oil leak. If gearbox
oil is changed, fill with 15 oz. of 80W-90 gear oil. Do
not overfill.
Drive Chain
Lubricate the drive chain every 8 hours. A light
penetrating oil or special purpose chain oil is recom-
mended. Lubricate the drive chain as follows:
1. Remove the three (3) screws fastening the
removable chain guard cover to the frame.
Remove Chain Guard Cover
WARNING
A brake stops the machine from free-
wheeling within five (5) seconds after dis-
engaging the PTO clutch. If the brake sys-
tem malfunctions and the machine does
not stop within five (5) seconds, the brake
should be adjusted or repaired before op-
erating the machine. Refer to the appro-
priate Tractor Owner’s Manual for
adjustment procedures.
WARNING
Remove the key from the ignition switch
when leaving the machine unattended.
This will prevent children and inexperi-
enced operators from starting the engine.
WARNING
DO NOT attempt to lubricate the machine
with the tractor engine running. Disen-
gage the PTO clutch, shut off the ma-
chine, and remove the ignition key.
