Auger System
Auger Fold System
The auger folding mechanism is hydraulically operated. When in the operating position it locks into
place by “breaking over center”. The screw adjustment that determines the locking pressure is set
at the factory so the auger will break over center and lock into place. Adjustments may be required
later to ensure auger snaps into locked position. If adjustment is necessary, extend threaded end
by ONLY one turn, then operate. Repeat if necessary. DO NOT OVER EXTEND! Grease weekly
when in use.

Drive System
PTO and (optional) Hydraulic Drive Systems
The drive system on the 850 consists of a gearbox which is mounted on the bottom end of the
auger and connected to the back drive shaft. The back drive shaft is then connected to the 1 3/8"
splined middle shaft. The middle drive shaft is then connected to either the PTO shaft (PTO drive
models) or a chain coupling and hydraulic motor (hydraulic drive models). The drive system is then
connected to the tractor by either the PTO shaft or hydraulic hoses.
