WARNING
To avoid serious injury or death:
Raise Disc Harrow out of the ground to make sharp turns. Do
not turn tractor tires into the tongue or frame. Doing this can
result in loss of control and/or damage the implement. Slow
down and watch tractor tires carefully when forced to make
1.
Raise unit out of the ground to make sharp turns.
When making sharp turns, make sure the tractor tires
do not make contact with the Disc Harrow hitch.
2. Do not disc in reverse (traveling backwards). The
Disc Harrow is designed to work soil while traveling
forward only. Damage to the harrow may occur.
3. Do not back Disc Harrow into corners and tight
places with disc gangs down. Instead, lift unit up and
back unit into the corner or tight area. Lower disc to
the ground and then proceed forward.
4. It is best to work ground traveling with a ditch and not
across. Raise Disc Harrow up to cross shallow
ditches straight on at 90 degrees. Crossing a ditch on
the diagonal can damage the disc and/or tractor
especially if a disc gang on one side digs into the
ground.
Never cross deep ditches
.
Unhook Disc Harrow
Unhook Disc Harrow from the tractor as follows:
1.
Park on a level solid surface.
2. Remove all stroke control spacers from hydraulic
cylinder and place on storage rack. Lower Disc
Harrow until wheels are resting on the ground.
3. Place tractor gear selector in park, set park brake,
shut tractor engine off, and remove switch key. Move
cylinder lift lever back and forth to release hydraulic
line pressure.
4. Rotate park jack on the tongue down and install
detent pin to lock park jack in place. Set jack to
desired height to maintain proper hook-up height.
5. Unhook hydraulic hoses from tractor and store hose
ends on hydraulic hose loop.
6. Un-bolt hitch from tractor. Once tractor is clear of
hitch, reinstall bolt, washers, and nuts to the Disc
Harrow clevis hitch for safe keeping.
7.
Harrow is to be stored for a long time.
NOTE:
Disc Harrows with disc blades spaced
7 1/2" apart are primarily used to pulverize soil. They
work best in tilled soil. Disc blades spaced 9" apart
are recommended for cutting non-tilled soil.
