DRILL MAINTENANCE
Proper servicing and adjustment is key to the long life of all farm equipment.
With careful and systematic inspection of your grain drill, you can avoid
costly maintenance, time and repair.
1.) After several hours of operation inspect all bolts and hydraulic fittings for
looseness or leakage. Refer to the torque chart in your operator's manual.
2.) Reference the operator's manual section 5 for all grease locations and intervals.
ADJUSTMENT BEFORE
GOING TO THE FIELD
1). Hitch drill to tractor and be certain to properly connect the hydraulic hoses.
Hoses with white plastic ties are for the fold circuit, blue ones are for the lift
circuit, and orange is for the markers.
2). Be certain that all warning lights are attached and functioning correctly. If unit
is equipped with a monitor, connect monitor lead to monitor harness. Connect
electric clutch cable to the switch control box cable.
3). Move handle on fold latch into field position. Carefully unfold drill and move
the drill to a level area.
4). Remove the transport lock channels and lift the drill fully to rephase the
cylinders. Lower the openers to the ground to make sure the drill is lowering
evenly. If the drill is not level, move the gauge-wheel eyebolts until the openers
on the outside end of the drill are the same height as the center openers.
5). Pull ahead slowly with the openers and coulters just touching the ground to
make sure that the track left by the coulter is centered on the opener.
6). Check for correct box alignment. Place a block of wood ahead of each wing
gauge wheel. Pull drill forward against blocks to rock frames back and insure
10-03
stop bolts are firm against the toolbars. Check for proper alignment by running a
string line across the back of drill toward outer wings. For proper alignment,
outside ends of boxes should be 1/4” to 1/2”ahead of inside ends. To adjust box
alignment, shorten or lengthen stop bolts to change the contact point with the tool
bars.
FIELD ADJUSTMENTS
1.) Move handle on fold latch from road to field position. Activate
hydraulics to unfold drill. Remove transport lock channels from center
section wheel cylinders.
2.) Make sure all seed meter clean out doors are in the correct position.
3.) Set the drive speed range sprockets as explained in the operator’s manual.
If the desired rate is not listed, use the ratios listed below to achieve the
desired rate.

4.) Set the seed rate Adjustment handle to the desired percent open.
5.) Load box with clean seed.
6.) Raise drill and rotate contact drive wheels. Check that all seed meters,
seed tubes, and drives are working properly.
7.) Pull forward, lower drill and begin seeding at field speed and check
overall setting of drill.
A). Inspect the actual depth of seed in several places along the drill.
Check 1: Behind the wing gauge wheels.
Check 2: Towards the outer end of the drill but not behind
the wing gauge wheel tracks.
Check 3: Behind the wheel tracks of the tractor.
Check 4: Towards the center of the drill but not behind
the tractor tracks.
This unit has several adjustments available to achieve consistent seeding
depth and even emergence across the entire unit.
COULTER HEIGHT ADJUSTMENT
1.) Hydraulic depth stop: The depth of the coulters is adjusted at the hydraulic
depth stop located on the left-hand wing section. Raising the depth stop will
increase the coulter depth. Lowering the depth stop will decrease the depth.
INDIVIDUAL COULTER ADJUSTMENT
1). Coulter pre-load adjustment: Maintain the no-till coulter tension spring
length at 10". This insures that the coulter has 400 to 450lbs. of base pre-load
and helps maintain a consistent coulter depth in hard and soft ground.
2). Individual coulter height: It is permissible to lower the coulters behind the
wheel tracks 1/2" by loosening the coulter attachment clamp and sliding the
coulter down. This adjustment is seldom needed. DO NOT LOWER ALL OF
THE COULTERS ON THE DRILL AT THE INDIVIDUAL CLAMPS.
DOING SO WILL HAVE A NEGATIVE IMPACT ON THE DRILLS
PERFORMANCE.
INDIVIDUAL ROW ADJUSTMENTS
1). Spring Pressure: The opener spring tension is adjustable. Place the openers
in the lightest setting. If needed spring pressure may be added to individual
rows behind wheel tracks only. Do not change the opener springs on the
openers not behind wheel tracks. Doing so will result in poor coulter
penetration and insufficient seed depth.

Maximum
2). Opener T-handle Adjustment: Moving the T-handle towards the front of the
opener will decrease the depth and moving the T-handle towards the rear of the
opener will increase the depth.
Point Row Clutch Rocker Switch: Lower openers until they are
almost ready to touch the ground. Loosen the worm drive clamp and
rotate the cam until the switch is just ready to make contact with the
ramp. Now raise openers and be sure that the switch is being
sufficiently depressed. NOTE: Do not over compress this switch or it
will become damaged.

Harrow Adjustment: (optional) Our harrow is designed to spread
the residue evenly. To adjust the harrow place the front bar 10 degrees
above the rear bar and the front row of teeth at a 40-degree angle and
the rear row at a 30-degree angle
