Loader Auxiliary Control will allow proportional operation of the attached work tool via the thumbroller on the loader control joystick. When the operator moves the loader auxiliary function thumbroller in the forward direction, the Loader Auxiliary Port B, J1-52 solenoid will be actuated.Loader Auxiliary Valve Solenoid 2
Loader Auxiliary Control will allow proportional operation of the attached work tool via the thumbroller on the loader control joystick. When the operator moves the loader auxiliary function thumbroller in the rearward direction, the Loader Auxiliary Port A, J1-51 solenoid will be actuated.Loader Auxiliary Reverse Direction Disable
Loader auxiliary control can disable the Loader Auxiliary Port B control through a configuration in ET. If Loader Auxiliary Hydraulic Circuit Configuration is set to one way, control of loader auxiliary port B shall be disabled. Control of loader auxiliary port A shall be allowed. If Loader Auxiliary Hydraulic Circuit Configuration is set to two-way, control of loader Auxiliary Port A and Loader Auxiliary Port B control shall be allowed.Hoe Auxiliary Valves

Hoe Auxiliary Valve #1 Control will allow proportional operation of the attached work tool via the thumbroller on the hoe control right joystick. When the operator moves the right joystick thumbroller in the forward direction, the Hoe Auxiliary Valve #1, Port B, J1-59 solenoid will be actuated. When the operator moves the right joystick thumbroller in the rearward direction, the Hoe Auxiliary Valve #1, Port A, J1-58 solenoid will be actuatedHoe Auxiliary Valve 2 Solenoids 1 & 2
Hoe Auxiliary Valve #2 Control will allow proportional operation of the attached work tool via the thumbroller on the hoe control left joystick. When the operator moves the left joystick thumbroller in the forward direction, the Hoe Auxiliary Valve #2, Port B, J1-62 solenoid will be actuated. When the operator moves the left joystick thumbroller in the rearward direction, the Hoe Auxiliary Valve #2, Port A, J1-61 solenoid will be actuatedMain Hydraulic Pump Solenoid
