Rotary Cutting Depth Adjustment
There are three options for setting your cutting depth.
They are gauge wheel drive, rear roller drive, and rear
roller drive with front roller. The option you use is
determined by your Overseeder drive type.
Gauge Wheel Drive
WARNING
!
Before making adjustments on the Overseeder, shut off tractor,
disengage power take-off, wait for all moving parts to stop,
and lock brakes before dismounting tractor. Be sure
Overseeder is securely supported on safe supporting stands.
1.
Start by adjusting the left-hand gauge wheel first.
Loosen the jam nut (#1) and back it off.
2. Rotate turnbuckle (#2) to shorten or lengthen it to
achieve proper depth, dimension (A).
3. Tighten jam nut (#1) to lock turnbuckle in place.
4. Adjust right-hand gauge wheel next. Lower
Overseeder to the ground and support the right
gauge wheel tire with a block beneath it, thus causing
the spring loaded gauge wheel link to bottom out.
5. Loosen jam nut (#3) and back it off.
6. Turn adjuster nut (#4) to shorten or lengthen spring
loaded link (#5).
7.
Dimension (B) should be the same on both right and
left-hand gauge wheels to achieve the same cutting
depth (A) at both ends of the Overseeder.
8. Adjust 3-point top center link at the tractor to re-level
the Overseeder.
Rear Roller Drive
1.
Raise or lower the lower arms on the tractor 3-point
hitch until the desired cutting depth is obtained.
2. Adjust rigid links as necessary by loosening jam
nuts (#1) and turning the turnbuckles (#2) to get a
firm pressing action on the packer wheels.
3. Tighten jam nuts making sure that dimension (A) is
equal in both sides.
NOTE:
The cutting depth of the knives is set by
adjusting the height of the gauge wheels.
NOTE:
Dimension (B) on the right-hand gauge wheel
can only be checked when the stop washer (#6) is
bottomed on the spring tube (#7) as shown.
NOTE:
The cutting depth of the knives is set by
raising or lowering the tractor’s lower 3-point arms.
