WARNING
front wheels, you must not exceed the ROPS
weight certification. Weigh the tractor and
equipment. Do NOT guess or estimate!
• The Medium and Heavy Duty Disc Harrows are
designed to fit Category 1 tractors equipped
with a standard 3-Point hitch. The tractor should
have a horsepower rating between 20 and 70
hp. NOTE: Some Category 0 tractors have
very short lift arms or 5/8” diameter (Cat 0) lift
arm ball ends. These tractors are not usually
suitable for using the Heavy Duty Disc Harrows.
ASSEMBLY
Unpack all bundles and lay out the parts.
NOTE: If your tractor lift arms spacing is 32”,
place the pins on the outside of the yoke legs. If
your tractor lift arms spacing is 26” or less, place
pins on the inner side of the yoke legs.
Assemble 3-Point hitch first.
Attach 3-Point straps to the front lower lugs using
7/8” lift pins, lock washers and 7/8” hex nuts. DO
NOT TIGHTEN AT THIS TIME.
Attach 3-Point brace to the Harrow’s center beam
with ¾” - 10 x 4½” GR5 hex head cap screw and
¾” lock nut. DO NOT TIGHTEN AT THIS TIME.
Insert ¾” - 10 x 5” GR5 hex head bolt through left
side of 3-Point brace, left 3-Point strap, spacer,
right 3-Point strap and out through the right side
of 3-Point brace. Secure with ¾” lock nut. Tighten
all connections at this time.
See finished detail below.
Be very careful when working around disc
blades as the edges are sharp. Always wear
gloves.
ATTACHING TO
TRACTOR
Never stand, or allow anyone else to stand,
between the tractor and the Disc Harrow while
backing the tractor up to the hitch.
Attach to the tractor’s 3-Point hitch as described
in the Tractor’s Operator’s Manual.
It is not recommended that sway bars or chains
be used with the Disc Harrow. The draw bar
should be checked to handle the weight of the
Harrow when the unit is being raised for the first
time.
Align lower link arms of tractor to hitch lugs on
the Disc Harrow. Insert lower lift pins into lower
ball swivels and attach lynch pins. Attach top link
to upper hitch of the Disc Harrow. Secure with
pins. NOTE: When using a Category 1 quick
hitch, the lower bushing of the upper hitch of the
Disc Harrow is the connecting point.
Check to see that the Disc Harrow is level front
to back. The Harrow is leveled by adjusting the
length of the tractor’s top link. Experience will
allow the operator to determine the best setting
for each application.
OPERATING
INSTRUCTIONS
Never allow anyone to stand between the
tractor and the Disc Harrow. Always stand to
the side until the tractor is in park.
Check the site for ditches, holes or obstacles
which could cause the tractor to roll. Make sure it
is clear of any debris which might cause damage
to the Harrow. Check with your local utility
company for buried electrical or gas lines.
DO NOT take a ditch at 90° (straight on).
Always go in at an angle or damage may
occur.
Be sure tractor tires and rims are in good working
condition and tires are properly inflated.
It is recommended that only tractors with wide
front axles be used with the Disc Harrow. Tricycle
front wheel arrangements are inherently unstable
