Unused Boxes
Unless steps are taken, all meter shafts of all boxes are
operating whenever the drill is lowered and moving. To
prevent needless wear, disable any unneeded ground
drive or box(es).
Ground Drive Lock-Up
On a drill with Native Grass, both left and right ground
drives will be operating unless one is disengaged.
To disengage, disconnect the ground drive spring rod of
the unused drive is from its normal (inner) operating
lug
, and reconnect it to a (outer) hold-up lug . This
operation requires a hoist or jack.
Refer to Figure 11
1.
Raise the drill and install lift locks (page 18).
2. Loosen the nut at the lower spring rod bolt .
3. Hoist or jack up the ground drive arm until the lower
bolt is loose. Remove the nut, washer and bolt.
4. Hoist or jack the arm up again until the spring rod
clevis is aligned with the hole in the outer lug
of
the arm.
5. Insert the bolt, and secure with washer and nut.
In this configuration, the locked-up drive never touches
the ground and does not turn.
This locked-up configuration does not disengage any
chains, and may also be used to make the ground drive
easier to access for calibration (page 33).
