OPERATOR INSTRUCTION
PRIEFERT MODEL 91 AUTOMATIC/MANUAL HEADGATE
MANUAL OPERATION
1.
2.
3.
Turn automatic selector lever (#9) toward rear of gate, disengaging it form operator’s handle (#8). This lever is located at
the top back corner of the gate above the operator handle.
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.
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 animal’s neck. Use same procedure for horned cattle, allowing more time for cow to enter. HINT: Stop horned
cattle prior to letting them put their head in the headgate.
To release cow, simply raise operator handle (#8) and 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 a width just wider than the cow’s head. (Do not be misled by “ears”!) Raise the automatic trip
control handle (#5) (red gripper handle), located on the top front-side of the headgate. Slide this handle it toward you, thus
positioning the automatic slide tube (#3) into position, which aligns the peg on the yoke nearest the operator with the
appropriate slot. Now, while holding the automatic trip control handle (#5) “up”, allow the gate to close until the
automatic slide tube (#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 best for small calves, 2) middle slot is for yearlings 3) slot nearest operator is for average 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 she attempts to force her way through, her shoulders apply pressure on the yokes. The trip
mechanism then releases the gate to 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 Headgate on the ground. The holes in gate mounting brackets will accommodate ½” bolts. Do not use lag screws .
(DIMENSIONS: Inside holes are 33” apart and outside holes are 36” apart, horizontally; top holes and bottom are 61 ¾” apart,
vertically.) Note: If mounting on cross ties or large posts, it will be necessary to notch the post on operator’s side to allow for
automatic selector lever in manual position.

LUBRICATION
LUBRICATE ANY and ALL WORKING PARTS with light oil at the beginning of each workday for best performance! It is
especially important to lubricate the locking mechanism inside the latch box (#1).
INSTRUCTION FOR REVERSING HEADGATE OPERATION
TO REVERSE HEADGATE OPERATION FROM THE LEFT SIDE TO RIGHT SIDE FOLLOWING THESE
INSTRUCTIONS. (Note: ALL HEADGATES ARE SHIPPED FROM THE FACTORY WITH THE
CONTROLS ON THE LEFT SIDE. Also, when referring to the left or right of the Headgate, consider how the
animal stands in the Headgate – “their right or their left.”
1. Remove operator handle (#8) by removing two ½” bolts and reattach handle to right side of Headgate.
2. Remove automatic selector lever (#9) by loosening and removing eyebolt from the lower end of the 10”
spring. Now pull selector lever out through the top of the gate. Reinstall on right side by reversing this
procedure. NOTE: You will need a screwdriver to stretch the 10” spring in order to get the eyebolt into bottom
bracket.
3. Disconnect the automatic slide rod (#4) from one end by removing the lynch pin and sliding the rod out of
the holes. Now slide the automatic slide tube with setting slots (#3) off of the automatic slide rod (#4).
Reverse the automatic slide tube with setting slots (#3) by turning the automatic slide tube end-for-end, and
slide tube back onto the automatic slide rod. This process will have the automatic trip control handle (#5)
pointed toward the “inside” of the Headgate. The handle will be turned “up”. To position it “down”, loosen the
locking nut that holds it locked in that position. Now, rotate the handle “down” and retighten the lock nut.
TROUBLESHOOTING:
PROBLEM
SOLUTION TO PROBLEM
Gate does not work smoothly.
1. Clean and lubricate all moving parts.
Gate failure to stay locked.
1. Lubricate latch boxes with WD40.
2. Be sure handle falls freely from unlocked position to lock
position. If not bolts on lift arms may be too tight. Handle must
fall freely in order for lock to hold.
3. Call 800-527-8616, Toll Free.
Gate hangs in open position.
1. Lubricate top rollers and all pivots and slides.
Gate is slow to close in automatic position, or does not close and
cow backs out.
1. Be sure automatic selector is engaged in notch of operator
handle.
2. Lubricate all moving parts.
3. If necessary, tighten springs at eye bolt to desired tension.
4.
Check automatic slide rod to be sure it is straight. If not,
straighten it or replace it. If automatic slide rod is bent,
the setting slot will not release; therefore, the gate can
not close.
5.
Lubricate slide rod.
