2) Engage the tractor PTO with engine idling, throttle so PTO reaches 500/540 rpm's and once the augers are
turning move the roller control lever to its upper position. Normally it is left in that position until the unloading
operation is finished (Fig. 23). Turn to the variable flow valve. This valve handles roller rotation speed through a
turning knob located at the top of the hydraulic valve array (Fig. 24). Turning the knob anti-clockwise
increases
rotational speed; turning it clockwise decreases it. The higher the speed, the more grain is brought in. At any point
during operation roller can be brought to a complete halt by closing the valve knob. Open the valve if it was
previously closed and augment speed so that grain begins to be delivered through the discharge auger and to
accumulate at the front end of the bag.
1) Make absolutely sure that the tractor's gear case is disengaged and brakes are off. Failure to
comply with this can result in a torn bag or mechanical malfunction. The machine is now ready to begin
unloading grain. First, pull up third lever “C” (Fig. 23) to turn roller forward about half a turn or more so
that it gatherssome plastic sheet (Fig. 21) and then move lever back to neutral. Check that the bag
passes through the cutter blade located on the auger tube (Fig. 22) in preparation for beginning work.
