Using the Calf Puller
1. Place breechen on the cow. Place the breechen against the cow’s rump with
the chain laying across the cow’s back just ahead of the pin bones.
2. Attach OB chain(s) to the calf’s legs. Attach OB chain(s) to each of the calf’s
legs. Note: Two OB chains are required for the alternating (zigzag) leg pull. Single
pull can be done with one or two OB chains.
3. Place rod and jack into breechen. Place the assembled rod (with jack in place
into the rod opening in the breechen.
4. Attach the chains to the jack.
Alternating (zigzag) pull:
If performing the alternating (zigzag)
leg pull, attach one OB chain to
hook A and attach the second OB
chain to hook B (see image labeled
“Attaching OB Chains”). When
ratcheting hook A and hook B will
move back in an alternating pulling
motion.
Single Pull: If performing a single pull and using two OB chains, attach one chain
to hook B and the second OB chain to hook C. If using only one OB chain loop
it over hook C (see image labeled “Attaching OB Chains”). Note: no OB chains
should be attached to hook A for single action pull.
5. Ratchet the calf free. Slowly and very carefully ratchet the jack until the pull is
complete.
6. Cleaning. After each use clean puller with a mild disinfectant.
Preparing Calf Puller for Use
Tightly screw together the rods. The rods must be screwed together tightly, as any
space between them may cause the jack to malfunction, or cause the rods to bend
or break.
Placing the Jack on the Rod
1. Slip the bottom half of the jack assembly onto the rod, on the opposite end from
the male pipe threads. Pressing the cam handles down onto their springs helps
the assembly slide onto the rod.
2. Once the jack is on the rod, ratchet the jack down the rod by applying a push/pull
motion to the jack handle.
Precautions
• If you are not familiar with the use of fetal extractors or pulling techniques,
consult with your veterinarian before use.
• The rods must be securely screwed together. So that there is no space between
them.
• Do not operate the jack past ¾ of the rod’s length (59" from the breechen).
If necessary, release and reposition the jack forward to complete the pull.
• Do not use the rod as a lever to assist in pulling.
Failure to follow these warnings may damage the rods
and jack, and injure the cow and/or calf.
