PARKING LOCK (See Fig. 6)
The mower is equipped with a parking lock (Fig. 6, Ref.
6) which keeps the 3-point hitch raised when the mower
is detached from the tractor.
NOTE: Refer to the Transporting chapter for
proper use of the parking lock.
BREAKAWAY LATCH (Fig. 7)
The mower is equipped with a breakaway latch and if an
obstruction is hit, the cutterbar must be free to swing
back. If the latch releases, stop the tractor immediately
and disengage the PTO. To reset the cutterbar, back the
mower until the cutterbar is in its normal position. DO
NOT raise the cutterbar to re-latch the breakaway.
Check for any cutterbar damage before resuming
operation after an obstruction is encountered.

IMPORTANT: Before using the mower, BE
SURE all sliding areas (Ref. 1) of the breakaway
latch mechanism are well greased and the
mechanism is operating properly.
Tension on the breakaway latch is determined by the
amount of compression on the spring washer stack (Ref.
3). The tension as set at the factory will be suitable for
most conditions. If the cutterbar continues to break
away, turn the adjustment bolt (Ref. 4) clockwise to
increase the breakaway pressure. (Refer to the Adjust-
ments chapter for additional information.)
IMPORTANT: DO NOT overtighten the
adjustment bolt.
IMPORTANT: In rough field conditions, ground
speed should be reduced to protect the machine
from damage.
TELESCOPING DRIVE COUPLER
(See Fig. 1)
The telescoping drive is equipped with spring-loaded
locking devices to positively lock it onto the tractor PTO
shaft and the disc mower input shaft. Depress the
locking device against the spring tension and slide the
yoke onto the tractor PTO shaft. Release the locking
device and move the yoke ahead or back until the lock
engages into the groove of the PTO shaft. The same
process is used to install the other end of the telescoping
drive line to the disc mower input shaft.
