3.7 FIELD OPERATION
OPERATING SAFETY
The disc should run level when 3-point hitch is
pre-adjusted as recommended and disc blades are
running between 3" to 5" deep. Depth of cut will
vary depending on soil type, moisture content and
weight of implement. Start working operation at a
slower comfortable speed; increase tractor speed
as clods reduce size. The types of soil, moisture
and weight on disc will determine how many
times you will have to go back and forth to get
the kind of seed bed desired. For harder or dryer
soils, additional weight may be added to improve
penetration. Always operate disc with hitch hy-
draulic control lever in lowered "
fl
oat" position.
Ridging, sometimes caused by rear outer discs,
can be reduced or eliminated by changing tractor
speed, shortening upper link, or a combination of
both.
Always lift disc before turning at ends
of
fi
eld.
Each operator should review this section of the
manual at the start of the season and as often as
required to be familiar with the machine.
CAUTION!
Be careful when working with Disc blades, as
the edges are sharp. Wear gloves when working
around disc blades.
1.
After initial adjustments have been made
and tractor is hooked up to Disc, you are
ready to start discing.
OPERATING SAFETY
1. Read Operator's Manual.
2. Lower tandem disc to the ground, stop
engine, set park brake, remove ignition key
and wait for all moving parts to stop before
servicing, adjusting and repairing.
3. Do not carry people on disc or frame.
4. Add weight to front of tractor to prevent
wheels from coming off the ground.
5. Stay away from overhead power lines. Elec-
trocution can occur without direct contact.
6. Use caution when operating on uneven ter-
rain. Decrease speed when making turns.
7. Use only with a unit with ROPS and a seat
belt.
8. Never allow disc to be left in the "up" position
when unattended.
9. Give complete undivided attention to the job
at hand.
10. Do not go under raised implement. Keep
others away.
2.
Lower Disc to ground and start moving
forward. Your travel speed will be
determined by soil conditions. You may
fi
nd
you want more or less angle on the discs to
do the job. Refer to Disc Gang Angle
Adjustment on page 15.
3.
When turning, always lift implement up
out of ground.
CAUTION!
Damage to the disc can occur if it is not lifted out of
the ground before turning.
4.
Do not disc in reverse (travel backwards).
The disc is designed for working the soil
while traveling forward only. Damage to
the harrow may occur. Recommended
procedure for corners or tight places is:
a.
Lift unit up
b.
Back up into corner or other tight areas
c.
Lower disc to ground and proceed with
discing going forward
5.
Do not cross a ditch at a 90
°
angle (straight
on). Damage to the disc and/or tractor may
occur while crossing at a 90
°
angle. Always
cross a ditch on a diagonal.
