A - B. AUTOMATED BUCKET METERING – used to im-
prove material metering out of the bucket at a consistent
rate. To engage automated functionality, move the joy-
stick rapidly back and forth from “A” Dump to “B” Rollback
position. The bucket accelerates more quickly while this
motion is maintained after 4 neutral point crossings. Reg-
ular bucket control resumes as soon as the back and forth
motion is stopped.
C. HOLD (central position) - The loader arms and bucket
will not move when the control lever is in the HOLD po-
sition. When released, the control lever will automatically
return to the HOLD position.
D. FLOAT – When in the FLOAT position, the loader
bucket floats across the rough ground.
