Trouble Shooting 12
1. Unit not tracking or is fishtailing
2. Unit not tracking: skipping, jumping, and
fishtailing(in untilled, hard soil)
3. Blades plugging with soil or trash.
A. Adjust top link to increase weight on the rear
of the disc
B. Disc assembled incorrectly. Refer to assem-
bly instructions.
A. Insure equal cut or depth on front and rear.
B. Reduce speed.
C. Reduce gang angle.
D. Reduce depth of cut by carrying on 3 point
lift discing shallow the first time over. NOTE:
Some experimentation may be required by trial
and error to arrive at proper solution.
A. Add optional heavy scraper kit(Page 17).
If already equipped, re-adjust them.
B. Soil conditions not suitable for discing due to
excessive moisture.
Gang Adjustment Trouble Shooting
Depth Control
The DH34 leveling system controls the harrow
from full depth penetration all the way up to
transport height. Once it is set for a particular
tractor, only minor adjustments will ever be
required. The springs also allow pressure con-
trolled flexibility when obstructions and/or
uneven terrain are encountered.
Most operating problems are caused by unequal
pressure and penetration of the front and rear
gangs. Adjust the leveling system to obtain
equal penetration by the front and rear gangs
and stabilize the direction and side shift of the
disk.
When making depth adjustments, be careful to
keep hands and feet clear of sliding parts and
possible pinch points.
Adjusting Gang Angles
The gang angles on the DH34 series disk are adjust-
able. The unit should be lifted two to three inches off
the ground with the tractor hydraulic system for an
easier adjustment. Each trial run should be made with
the tractor in the same gear and approximately the
same RPM. Keep in mind that many variables affect
the operation of your disk. These include, but are not
limited to penetration, speed, soil conditions, etc.
To adjust the front and rear gang angles, remove the
gang angle adjusting bar (ref. #1, figure 2) from the
stud (ref. #4, figure 2) on main frame (ref. #6, figure
2). Insert stud (ref. #2, figure 2) on angle adjusting
lever (ref. #3, figure 2) into hole (ref. #5, figure2) on
gang angle adjusting bar (ref. #1, figure 2). This will
allow you to use leverage to increase or decrease
gang angle. Once desired angle is set, apply gang
angle adjusting bar (ref. #1, figure 2) back on main
frame stud (ref. #4, figure 2) and pin off to secure.
Angle adjusting lever (ref. #3, figure 2) should be posi-
tioned to rest on top of frame.
When making gang adjustments, be careful to
keep hands and feet clear of sliding parts and
possible pinch points.
