CAUTION
and can cause rollover accidents.
On soils with light to medium plant cover, it is
usually acceptable to disc the ground once or
twice to cut up the plant growth to prepare the
soil. In most cases, multiple passes may be
required to achieve the desired soil preparation.
Adding additional weight to the Disc Harrow will
aid it in cutting deeper into the soil. It will also
require an increase in your tractor’s horsepower.
Do not attempt to disc wet or mucky soil. All
areas should be well drained and capable of
being walked on without having soil stick to your
shoes.
Ground conditions and the finish you require will
determine the angle position of the front and rear
gangs. The sharper the angle is set, the more
aggressive the cutting action in the soil profile
will be.
If the soil is building up or sticking to the
discs, the soil is too wet and discing should be
discontinued until the ground is drier and more
workable.
The speed of the tractor will be determined
by the condition of the soil. You may need to
use more or less angle depending on the job.
Speed of the tractor should not exceed 5 mph.
Operating at faster speeds will not allow for good
penetration into the soil and can cause damage
to the blades. When you are turning, lift the unit
from the ground.
Successive passes should be made with outer
blade approximately 7” from the previous pass
to match spacing and prevent ridging.
Do NOT disc in reverse. The Disc Harrow was
designed to only go forward. For turns in tight
places, lift unit up, back into a corner or other
tight area, then lower disc to the ground and
proceed to disc forward.
Adjusting Disc Angles
By adjusting the gangs in the front and rear,
you are able to set the disc to different angles,
depending on the tillage desired.
On the Heavy Duty models there are four
positions in the front and rear. On the Medium
and Sub Compact models there are two
adjustment positions for the front and rear.
Before adjusting, raise Harrow off the ground.
Adjust the desired angle by removing the bolt(s)
and nut(s), slide the gang to the desired position
and rebolt.
TRANSPORT SAFETY
• Always observe state and local laws governing
highway safety and the travel of farm
machinery on public roads.
• The use of flashing amber lights is acceptable
in most locations. However, some locations
prohibit their use. Local laws should
be checked for all lighting and marking
requirements.
• When driving the tractor and equipment on
roads or highways, use flashing amber warning
lights and a slow moving vehicle (SMV)
identification emblem. Do not exceed 20 mph.
Reduce speed on rough roads and surfaces.
• Plan your route to avoid heavy traffic.
• Always install transport locks, pins or brackets
before transporting.
• Do not drink and drive.
• Be a safe and courteous driver. Always yield to
oncoming traffic in all circumstances, including
narrow bridges, intersections, etc. Watch for
traffic when crossing or operating in close
proximity to roadways.
• Turn curves and go up and down hills only at a
low speed at a gradual steering angle. Make
certain that at least 20% of the tractor’s weight
is on the front wheels to maintain safe control.
Always check tractor manual for proper use on
slopes.
• Use extreme care and maintain minimum
ground speed when operating close to ditches
and/or fences. Be careful when turning sharp
corners.
• NEVER allow riders on either the tractor or Disc
Harrow.
