Description
The 2 Pcs ratchet style calf puller with extra 60″ OB chain set is a comprehensive veterinary obstetrics kit designed to assist with difficult bovine births (dystocia). The SAG Surgical ratchet style calf puller set includes two complete calf puller units with extra 60-inch OB chains, engineered for safe, controlled extraction during calving emergencies.
This calf puller set is uniquely crafted with a robust ratchet-style mechanism that provides uniform tension without slipping or backing up. Traction on the calf and the counter-thrust against the cow induce spreading of the pelvic bones and arching of the animal’s back, all assisting in the natural birthing process . The calving extractor offers controlled, one-click-at-a-time operation, and if necessary, controlled release one click at a time. The ratchet mechanism on this bovine delivery instrument moves smoothly up and down the pole, with deeply cut threads preventing slipping .
The calf puller features a breechen (hip strap) that fits securely against the cow’s rump, distributing the pulling force safely. The smooth rods unscrew for easy storage and cleaning . The 60-inch OB chains included in this cattle delivery set provide ample length for secure attachment to the calf’s legs, with experts recommending 60-inch chains over shorter options for their versatility and secure grip .
Ratchet style calf pullers are used across various veterinary settings including cattle operations, dairy farms, veterinary clinics, and large animal facilities. This veterinary obstetrics kit assists veterinarians and livestock producers in managing dystocia cases, ensuring safer outcomes for both mother and calf. Producers are recommended to have a calf puller, chains, and a head snare as part of their calving equipment .
Veterinary obstetrics instruments are manufactured to the highest standards using high-quality materials. This ensures that every calf puller set maintains its strength and reliability for years to come. This calving extractor is designed for easy cleaning and disinfection, maintaining high hygiene standards.
SAG Surgical takes pride in offering premium ratchet style calf puller sets that meet the demanding requirements of modern veterinary practice. Every calf puller undergoes rigorous quality control to ensure consistent performance and safety.

Important Safety Considerations
-
Never use a calf puller unless both shoulders and the head of the calf can be delivered into the pelvis by hand first (“Rule of Three”)Â
-
A calf puller can apply significant force, so improper use can cause serious injury including broken ribs, fractured legs, or spinal fracturesÂ
-
Always double-loop the chain above the fetlock and with a half hitch below the dewclawsÂ
-
Work with the cow’s contractions and never apply sustained tractionÂ
-
A calf puller should only be used by trained personnel or under veterinary supervisionÂ
