Rurtec Chinmark Bull Mating Harness for Cattle
Description
Rurtec Chinmark Bull Mating Harness
The Rurtec Chinmark Bull Mating Harness is a chin-mounted marking harness that holds a crayon under a bull's chin so every mount leaves a coloured mark along the cow or heifer's back. It is designed for beef and dairy farmers, herd managers and graziers who need a simple, reusable way to identify served females during the mating period.
Wide straps keep the harness comfortable on working bulls, while the click in crayon holder makes changing crayons a quick job in the yard. It is suitable for use with Matingmark crayons, which are bought separately.

- Simple click in crayon holder for fast, tool-free crayon changes

FAQ
What does a bull mating harness do?
It holds a marking crayon under the bull's chin. When the bull mounts a cow or heifer, the crayon leaves a coloured line along her back, showing that she has been served.
Are crayons included with the harness?
No. The harness uses the click in crayon holder and is suitable for Matingmark crayons, which are purchased separately.
Will it fit any bull?
The straps are wide and easily adjusted, so the harness suits a range of bull sizes and head shapes. Always check the fit once the harness is on and readjust if the bull's condition changes during mating.
How often should I check the harness?
Check it regularly through the mating period. Look at strap tension, make sure nothing is rubbing, and replace the crayon when the marks start to fade.
Can it be used again next season?
Yes. Clean off mud and dirt after use and store the harness dry, and it can be reused for following mating periods.
How do I change the crayon?
Restrain the bull, release the used crayon from the holder and click a fresh crayon into place. No tools are required.
