    Hi all, as per subject title, any recommendations on a shear grab welcome. I've never had a shear grab, had bales for a few years but pit this year and the old tine fork is not good enough. Its going on a 100hp tractor so nothing too heavy. Thanks

    Have a 4' McHale here this 15 years and I bought it 2nd hand. Needed new tines twice and new bushes this year as well as tines. I have fed 2000 acres of silage or so with it, the majority on NH TL90 with no problems. Imo the life of them is keeping the tines 1/2" off the ground when cutting the bottom block. It saves wear on the frame and the ends of the tines. Keep the tines tight too or the bushes will last no length.

    Have a 1m grab made by Brody’s in Athenry since 88. It’s a lot like triggers broom at this stage. Rams on the blade were never touched, yet.

    The bigger they are the more likely they are to fall apart IMHO. 4 ft should suit you I reckon. Watch out buying second hand though, tines break in the bushes and then a bolt can be welded on. Avoid rusty rams too.

    If the seat's wet, sit on yer hat, a cool head is better than a wet ar5e.

    +1 for avoiding too big. For most tractors in 80-120hp range a 4ft is a perfect size. There is a lot of force being put through the blades to cut and this is what causes a lot of the problems. Keep them sharpened is the key. 5 mins once a week with a hand file is great. I keep the file in the tractor. Part of the Sunday morning routine in winter is a quick sharpen and a grease of the loader.

    Over 4ft the grab can twist as the force being put on is in even. Look at the majority of the 6ft up ones. They are three rams and have a centre piece. This helps to keep things rigid.

    On a side note here. I feed the bales with a tine grab, just quicker and easier, have a 4ft for the pit
