Priefert 91 Operator Instructions

Priefert Model 91 Automatic/Manual Headgate
Caution
Be familiar with handling livestock prior to use of this equipment. Working with livestock carries inherent risk
of injury or death. See page 3 for additional information on safe practices for handling of livestock.
Manual Operation
1. Turn automatic selector lever (#9) toward rear of gate, disengaging it from operator's handle (#8).
This lever is located at the top back corner of the gate above the operator handle.
2. The gate's latch boxes (#1) (locking mechanism) are automatically disengaged when the handle is
raised. This allows for opening the gate to a desired opening.
3. Catch cow by opening the gate just wide enough for animal's head to enter; as the cow's head
enters, pull handle down locking the animal's neck. Use same procedure for horned cattle,
allowing more time for cow to enter.
4. To release cow, simply raise operator handle (#8) to open gate fully, allowing cow to walk through
the headgate.
Automatic Operation
1. Turn automatic selector lever (#9) forward to engage it into notch in operator handle (#8). This
lever is located at the top back corner of gate (same lever mentioned in sentence #1 under manual
operation).
2. Open the headgate to an open width wider than the cow's head to be caught. Raise the automatic
trip control handle (#5) (red gripper handle), located at the top front side of the gate. Raise the
handle and slide it toward you, thus positioning the automatic slide tube with setting slots (#3) into
the desired position with the appropriate slot aligned with the peg on the yoke nearest the operator.
Now while holding the automatic trip control handle (#5) "up", allow the gate to close until the
automatic slide tube with setting slots (#3) is resting between the pegs thus holding the yokes just
wide enough apart for the cow's head to enter, but not wide enough for her shoulders to get
through. (NOTE: Recommended settings are 1) slot farthest away from operator is for calf, 2)
middle slot is for heifer 3) slot nearest operator is for cow and 4) position the setting bracket
"end-to-end" between pegs to catch a large cow or bull).
3. Now the gate is set and ready to catch the cow. Stand back or prod the cow up the crowd alley
toward the headgate; as her head enters the gate and her shoulders attempt to spread the yokes, the
trip mechanism will release and gate will shut on animal's neck, preventing her from backing out
of the headgate. To make the headgate trip easier, you may want to "hair trigger" it by just
catching the edges of the pegs in the slots when using the automatic feature on small calves and
unusually gentle animals.
Installation
Mount gate on the ground. The holes in gate mounting brackets will accommodate ½" bolts. Lag
screws are not recommended (DIMENSIONS: Inside holes are 33" apart and outside holes are 36"
apart, horizontally; top holes and bottom are 61¾" apart, vertically.
