Preparation and Setup
Hitching to Tractor
This planter can come installed with either a universal
category III and IV hitch or unchangeable category IV wide
hitch. Both require a tractor with a quick attach hitch.
You can off-center the planter’s hitch alignment by
adding or removing hardware. See “
Crushing Hazard:
Do not stand or place any part of your body between the
planter and moving tractor. You may be severely injured or
killed by being crushed between the tractor and planter. Stop
tractor engine and set parking brake before making hitch
adjustments and connections.
If changing the category of a universal hitch, a top and
lower link adjustment are required.
Top Link Adjustments
Make a top link (1) adjustment only if changing the
category of hitch or after adding lift assist to machine.
Planters without lift assist must use a category IV hitch.
Lift Assist
For planters without lift assist, place pin in specified hole
(A). Planters with lift assist do not place a pin in hole (A).
Gauge Wheel Settings
For planters using a category III hitch with rear mounted
gauge wheels, install stop plate (2) with pin through hole (D).
For planters using a category IV hitch with rear mounted
gauge wheels, install stop plate (2) with pin through hole (E).
NOTE: The stop plate (2) is not used on planters with
front mounted gauge wheels.
Lower Link Adjustments
Make a lower link (3) adjustment only if changing the
category of hitch or offsetting hitch tractor alignment.
Altering Hitch Category
Changing the hitch category requires reconfiguring shims
and other hardware used. Refer to “
on page 123 for layouts of different hitch categories.
Offsetting Hitch Alignment
For planting on beds, you may desire a slight off-centering of the
machine. To do so, unhitch tractor hooks from couplings, and
then separate the round shim (5) from the spacer (6) by moving
it to the opposite side of the pin (7) as shown in Figure 5.
If more than 1/2” of off-centering is desired or hitch is category III
narrow, move additional available slide-out shims (4) from
mounting plate (A) and reinstall them against opposite
inside-facing surface of mounting plate (B) as shown. Move no
more than 1” of shims from the default category hitch
configurations shown on page 123.
