Loader Joystick Functions
NOTE:
Early model tractor shown. Later model tractors are similar.
The control lever for the loader valve (F) has four directions of movement to enable simultaneous control of two functions.
Forward and back direction (A) has the following positions:
-
Pulled fully rearward-Bucket raise position.
Loader valve boom couplers (D) are normally connected to the loader boom cylinder and raise the boom when the lever is pulled rearward.
-
Spring centered-Off and locked position.
Loader valve is locked to hold the boom and bucket in position.
-
Pushed slightly forward-Bucket lower position.
Boom cylinder is lowered; valve can be metered to control rate of lowering.
-
Pushed fully forward-Float position.
Loader valve connects both cylinder ports to the return circuit. Loader boom can move freely to follow ground contour. Lever must be manually returned to neutral.
Inward and outward direction (B) has the following positions:
-
Pushed outward-Bucket dump position.
Loader valve bucket couplers (E) are normally connected to the bucket cylinder and dump the bucket when the lever is moved to the right.
-
Pushed fully outward-Regenerative position.
Provides faster loader bucket dump. Reduces cavitation. Lever returned to neutral by valve spring.
