Just straightened bent locking tubes on the headlocks I moved to the heifer field. Years of the big cows pulling against them during vet checks bent them on the bottom, so the smaller heifers could lower their heads & slip out on me, or at least some of them could. I need to use pour on wormer on them, so I needed to get this issue resolved. I decided to use a screw jack from a car. I welded ears on the top side to keep it from slipping off the pipe. In the first pic you can see how the hinged pipe isn't straight.
Now hand wrenching the screw jack would have taken forever & got my neck & shoulders hurting. But I have a secret weapon....a hydraulic impact wrench I can run off a tractor. It is extremely powerful. My brother gave it to me. His work got new ones & tossed this one in the dumpster. So glad he saved it! I already had several feet of hydraulic hose and the fittings.
I slipped a piece of 4x4 into the top side to hold the tubing in place, held snug by a rubber bungee cord.
After straightening. Took a bit over an hour to do all 35 headlocks.
Tomorrow they get wormer applied!
