OPERATION
General Operation
1. The minimum horsepower requirements are typically
10-12 horsepower per foot of width. This will vary
widely due to speed, depth, moisture, residue and
types of soils. Local dealers can help in making
recommendations for your areas.
2. Operating speed is typically 5-8 mph. Excessive
speed can cause rapid sweep/point wear. Reduce
speed in rocky conditions to prevent wheel breakage.
3. Front and Rear Rollers are used to gauge the depth
of the shanks. See Figure 3-4.
4. Do not turn with the Shanks in the ground, this can put
excessive side load on the Shanks. Raise the Shanks
using Hydraulic Tooth Control when making turns to
prevent bent or broken Shanks.
5. Turn off active Wing Down Pressure, put Wing Fold
Circuit in float when turning.
6. Users that prefer to raise the Machine when they turn
around and want to reduce the amount of Wing down
float (droop), may choose to install Optional Wing
Fold Hydraulic Cylinders with Internal Stop. See
Figure 2-84.
CAUTION
Failure to remove both Locks will cause damage
to the Rockshaft.
