    Most of the actual 'Calving' is done by leverage rather than ratcheting. You can put on some pressure with leverage.
    I did break a calfs leg once, 18mths ago. One of the calving ropes snapped under pressure and I slipped sideways and done the harm. The calf went ahead well after and you'd never know it was broken now!
    The moral of the story is this though. Throw away those light white calving ropes and buy a set of the heavier Red/Blue ones, they're a much better job.

    Your right Bizzum, the heavier red/blue ropes are a lot easier on the calf and last a lot longer. We dont use anything else with the technall jack. i get them here http://www.agridirect.ie/index.php/veterinary-equipment/cattle/calving/vink-nylon-calving-ropes-pair.html

    Was thinking of upgrading my jack to the Vink jack myself. Have a technal jack but tends to slip down at the back. The head on the vink is supposed to hold better on the pin bones. Is it worth the investment.

    I've never used the Vink jack Johnny.
    I wonder would they be available on line? Maybe Agridirect would have them?
    Are Agridirect any good?
    Did you ever buy off Agridirect?
    Isn't is a lovely word.............Agridirect..........Agridirect...........Agridirect
    I can't get it out of my head now:D

    Only bought off them a couple of times. Had it within a few days so i was happy enough. Also rang them once as i wanted more info on dosing and they were quite helpful. You have to shop around these days though.

    Would you not move the ropes up above the knee with a tuff pull bizzum. I always would. Its a lot easier to control the pull and less of a chance of breaking the calfs leg aswell.

    Ive tryed a good few types at this stage(I'm a vet),and my personal favourite is the Technal type jack.
    THe Hk round bodies can be tricky to release pressure on and in general can be a bit awkward to use, the vink is a very good jack but I found the exerted even more pressure than the teachal on the cow with less manual strength needed and many of the calves pulled really should have been sections...ie seen a good few downer cows after that jack,thought that might have been just the farmers in question. Good in a tricky situation but I personally dont like them over the technal. Plus in a very very bad situation on the technal you can attach a lever to the handle to allow you more ratcheting power..you cant do that on the vink.You have the same high force all along.

    Technal is a nice easy to ratchet shaft,easy to release and reposition,can be halved in a a tricky situation ie if the cow goes down awkwardly....and if you are feeling the pressure on that jack early on unless the cows got a very tight bearing you are as well to start thinking of the side option. Didnt find the head slipped that much than any of the others, but then again Im never alone when im using the jack.

    Agree as well that the leverage is as important as the ratchet pulling!and the coloured ropes..great job those.

    Attaching a jack is the equivalent of attaching the tractor, its just more direct force.

    I have had that one for nearly 20 years, its had a lot of use, absolutely fantastic, really well built, never slipped, never let me down.

    Before that I used one of the older design with the round steel shaft and the smooth "thread", rather than the teeth and the squarer aluminium (i think) shaft on this Tecnall jack. The older ones were awful things for slipping.

    The only flaw I have of mine is that the Moorepark head was made of very lightly galvanised steel, and it has rusted badly, but works fine (stiff joints on it now). the shaft and ratchet are still like new.

    Super piece of design, I am delighted to see it is unchanged, a great endorsement of a product to keep it exactly the same for so long. Right up there with the vice grips as a unique product where I regularly say a small prayer for whoever invented it!

    Same story here. The head has completely rusted up but apart from being a bit stiff it works fine. Was thinking of getting a replacement head and have seen them on Magenta Direct for around €25. Full kit (Moorepark Head and Square shaft) is €120 and was even thinking of getting it as a backup if the old one ever gives in.
