8. Hydraulic Disc Operation.
a. Lower the discs and hold the valve until all
cylinders are completely extended. Then raise
the discs.

desired working depth.
IMPORTANT
Use the depth gauge for relative depth of discs. it
does not indicate actual depth of discs.
c. Position the discs at desired depth by extending
or retracting the disc adjust hydraulic cylinder(s).
d. Adjust the wing discs to operate at the same
depth as the center discs by adjusting the screw

Figure 3-21.)
e. Manually adjust discs: Adjust the ratchet jack on
each disc gang to the desired depth. Insure that
all discs are set at the same depth.

CAUTION
10. Harrows
a. Coil Tine (3 and 4 bar): Position the spring
anchor bolt to get the desired pressure on the
harrow teeth. Position bolt in the harrow linkage
assembly so that the harrow assembly is level.
Place the stop bolt to get the desired angle on
the harrow teeth (See Figure 4-5.)
b. Spike Tooth Drag Harrow (3 and 5 bar): Adjust
the harrow up or down until the lower portion of
the harrow frame is level with the ground when
the unit is at working depth (See Figure 4-6.)
c. Spike Harrow (Tilloll style): The harrow as
assembled is set for a working depth of 3 to 5
inches. Adjust the harrow up or down to change
the working depth. Spring tension can be
increased by reducing the number of chain links
between spring and anchor bolts. Adjust the
angle of the harrow teeth placing clevis pin and
cotter pin in one of three holes in the harrow
adjustment brackets (See Figure 4-7.)
d. Chain Spike Harrow: The harrow height may be
adjusted be removing the 1/2-13 x 1-1/4 hex
head cap screw, flat washer, and hex lock nut on
the chain and moving it up or down a link. The
leading chain can be adjusted with a quick pin
inserted in the top or bottom slot. Recommend a
test run in the field for accurate adjustment
settings (See Figure 4-8.)
