DANGER
Do not connect or disconnect mower to tractor with upper
spring (#9) connected to pin (B). The upper spring pulls on
3-point main frame and will quickly turn main frame upon
removing one of the tractor’s 3-point arms.
The upper spring (#9) should be connected to pin (B)
after mower has been hooked-up to a tractor and
disconnected from pin (B) before unhooking mower from
a tractor.
After Hooking-up Mower to Tractor
Attach upper spring (#9) by retracting hydraulic cylinder
until spring’s slotted bar is inserted over pin (B). Secure
upper spring to pin (B) with flat washer (#12) and linch
pin (#13).
Before Unhooking Mower From Tractor
Disconnect upper spring (#9) by retracting hydraulic
cylinder until upper spring slotted bar can be removed
from pin (B). Remove flat washer (#12), linch pin (#13),
and slotted bar from pin (B). Return washer and linch pin
to pin (B) for storage.
