7.7  Spring-return Pivot

(LXG420S, LXG430S models)

The LXG–'

S

' models have a return-to-center spring pivot on the 

grapple. The pivot can be locked, or left unlocked for carrying 
a load or skidding. The pivot is protected by a shear bolt if 
excessive torque loads occur. 

The same lifting and skidding procedures can be applied to 
spring return pivot, but the grapple must be manually positioned. 
Follow the procedure below:

IMPORTANT!  Make sure the pivot is UNLOCKED during 
skidding. Damage to the pivot can occur if locked when 
turning or contacting other objects.

7.7.1  To Unlock Pivot

• 

Pull down on the grapple lock lever out of the Lock position 
notch. Turning the grapple slightly may be required. 

• 

Rotate the lock lever around by hand to the far side and 
release it into the Unlock position notch. The grapple can 
now rotate freely.

• 

Reverse the procedure to lock the pivot.
