5. Ending grain extraction sufficient plastic is unrolled either hydraulically or by mechanically disengaging the roller for the bag to be sealed with plastic strips or 2 x 4 boards nailed together Whenever grain extraction is ended either if the unloader will remain with bag attached to continue work later or if it will be towed away the correct termination sequence is as follows a Theroller is brought to a complete standstill by setting valve lever in neutral position or closing flow control knob in order to stop the input of grain b is left engaged and working for a few minutes so that all loose grain is unloaded ensuring there is no buildup inside the discharge auger tube that could be cause of transmission overload and breakdown 1 When the unloader reaches a point where it can advance no further because the bag is almost Emptying the last section of bag finished and the augers are not picking up any more grain Fig 27 it is time to cut short the main operation After stopping hydraulics and stopping the PTO for reason of safety the operator should use a knife to rip open the upper part of the bag remove stops and lower the machine so that the augers may pick up additional grain Fig 28 while the roller remains stationary The tractor can engage in some gentle forward and reverse action to boost grain collection Repeating this sweeping action the volume to be loaded by hand can be considera
6. bag goes too high the roller must be slowed down to allow more grain to be removed by the sweeper and discharge augers Grain picked up and rolled as one with the plastic sheet is the telltale sign that should be watched out for The roller extremes where the plastic folds converge on the centering discs is where grain is more likely to collect grain is being picked up then roller speed has to be reduced If the roller picks up too much grain resulting in prominent and growing bulges under the plastic it will be necessary to stop operation cut the bag remove plastic sheet from roller and reinitiate operation G If grain height reaches point where a substantial amount of grain is being unloaded with none being picked up the roller then roller speed should be stabilized there Usually point A is the highest point that the grain can reach without being pulled in with the plastic folds but the actual clearance to the roller measured in centimeters can vary When this plateau is reached the roller is turning at the correct speed H This is the point of equilibrium where inflow and outflow of grain are equal The amount of grain that can be handled has reached its peak ncreasing discharge speed should not be attempted at this stage since no benefit in terms of time or volume will be obtained and failure of mechanical parts is a possibility l If in doubt first always try working slower before increasing speed in

8. will stretch and straighten after a few turns of the roller The basic consideration here is having the bottom part of the bag the part hooked to the roller first hold some slack relative to the upper part attached last one or two feet is enough The latter should be attached shorter so that the roller tugs at it first The small margin of slack in the bottom section plus the plastic sheet s elasticity helps form a rounded shape that contains the grain as the bag is rolled in The round shape also helps keep adequate clearance between bag and sweep augers see General indications for efficient operation page 26 Grain extraction procedure 1 Make absolutely sure that the tractor s gear case is disengaged and brakes are off Failure to f comply with this can result in a torn bag or mechanical malfunction The machine is now ready to begin unloading grain First use control lever to turn roller forward about half a turn or more so that it gathers some 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 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 ro
9. A is the height that grain within the bag can be taken to by increasing or reducing the pickup roller s RPM s This level must not exceed the roller s height to prevent grain from being picked up with the plastic sheet With this constraint grain level should normally be maintained as high as possible so that with the aid of gravity it can readily fall back onto the sweep augers and be directed to the discharge auger shows the curved shape that the front part of the bag should adopt Figs 41 amp 42 in order that the plastic sheet does not come in contact with the sweep augers or their protection grids with risk of ripping open and losing contents The curvature is formed by the grain mass weighing down the tip of the bag as it is rolled in When grain does not accumulate there the plastic will tend to go up to the roller in a straight line Fig 43 dangerously close to or actually touching the augers with possibility of bag damage With grain that flows easily e g dry wheat if the sweep augers are set with their normal low clearance to the ground see C below it can happen that due to quick passage no layer of grain is left between the sweep augers and the floor With no grain weighing down the bottom part of the bag and grain being unloaded at a very fast pace because it flows freely it might not accumulate at the front as in fig 41 but take on the shape shown in Fig 43 In this case sweeper height should be in
