General Information
Pickup Clutch
FIG. 3: The pickup clutch (1) protects the pickup
assembly. The clutch is both an overrunning clutch and a
slip clutch that can not be adjusted.
Pickup and Feeding
The crop is picked up and fed into the baler continuously
by a four bar pickup assembly. The height of the tines
above the ground is set by the pickup height adjustment
gauge plate. Flotation is supplied by a flotation spring that
supports much of the weight of the pickup assembly. An
adjustable flotation spring carries most of the weight of
the pickup. Gauge wheels protect the pickup when baling
on ground that is not even.
Two centering augers move material from the ends of the
pickup into the center of the pickup. The stuffer fingers
move the crop through the charge chamber into the bale
chamber. The plunger then compresses the crop against
the bale being formed in the bale chamber.
Hydraulic System
The hydraulic system is used to raise and lower the
pickup, swing the baler, and to control the bale density.
Power is supplied by a pump driven by a belt from the
drive shaft connected to the PTO.
Bale Density System
The density and weight of the bale is determined by the
amount of resistance to the material moving through the
bale chamber. This resistance is determined by the
amount of hydraulic pressure applied to the density
control rails. Increasing the hydraulic pressure increases
the density and the weight of the bale. Decreasing the
hydraulic pressure decreases the density and the bale
weight.
