Spring Shank; Sweeps - Landoll 9630FH Operator's Manual

Spring Shank

1. The Field Cultivator may be equipped with spring
shanks. The spring shanks feature a 185 lb. point
load and a 10" trip height to clear field obstructions.
Shanks are 5/8 x 1-3/4 heat treated steel.
2. There is no regular maintenance required on the
shanks. The main pivot point of the spring shank has
replaceable hardened wear bushings that pivot on a
heat treated clamp bushing.
NOTE
Main pivot bolt should be tightened securely to prevent
rotation. Torque main pivot bolt to 140 ft.-lbs.
3. When adjusting/assembling the spring assembly,
tighten the upper spring bolt, but leave approximately
1/8" gap above the spring jam nut
This will leave the proper clearance for the spring to
pivot. Lock the jam nut against the top of the spring,
not the top of the mount. Likewise do not over tighten
the lower spring cross bolt. Remove any slack in the
bolt, but still allow the lower spring to pivot freely.

Sweeps

1. The spring or s-tine shanks will accept a wide variety
of sweeps and points. Recommended sweeps for the
cultivator are standard 47º sweeps in 7 to 10 inch
widths using 7/16 diameter mounting hardware.
Check clearances when using larger sweeps to avoid
interference with tires.
See Figure 4-9.
