Buhler 2425, 2335, 2290 Rotary Lowering Rate Control Knob, Rate of Hitch Raise Adjustment, 138

SECTION 2 - OPERATION

Rotary Lowering Rate Control Knob

Knob, 1, is used to set the rate at which the implement will drop to the ground. Turn the knob clockwise to increase the lowering rate and counterclockwise to decrease the lowering rate.

NOTE: Each time an implement is changed on the tractor, the lowering rate must be reset for that particular implement.

The control operates in the manual and automatic mode with the exception of the automatic float mode.

Rate of Hitch Raise Adjustment

The electrohydraulic valve has a flow control adjustment located at the front of the valve that will determine the rate at which the 3-point hitch will raise.

To access the flow control adjustment, the rear frame deck shield, 1, must be removed from above the implement valve. Loosen the four screws, 2, that attach the shield to the tractor and lift if off.

Turn the adjustment, 1, counterclockwise to increase the rate of raise and clockwise to decrease the rate of raise. The operator can set this adjustment to any position desired for the implement attached to the tractor.

WARNING: ONLY ADJUST THE RAISE RATE WHEN THE 3-POINT HITCH CONTROLS ARE IN NEUTRAL AND THE TRACTOR IS SHUT OFF. ENGAGE THE ARTICULATION LOCK WHEN WORKING IN THE ARTICULATION AREA.
