Bush Hog Shear Pins

JAY AND EBBEN · Post by **JAY AND EBBEN** » Wed Jul 13, 2011 6:51 pm

We have a bush hog squealer (4 foot). We need help with what to buy for shear pins and where they go. I THINK they would go on the drive shaft, but then again have no idea. Any help would be great...
Thanks,

Stop using shear pins and use a replacement torque clutch. Far better and less maintenance.

I have a 6 foot King Kutter 3 point hitch (single rear caster wheel).
I buy Grade 2 bolts with nuts and lock washers (shear pins) for less than $.50 each set. I carry two wrenches in my tractor battery box and several shear pin sets. I use a new bolt if I need something to get the piece of the old bolt out.
I seldom shear a pin and it is always when I forget to raise the mower and hit a hump of dirt.
It works and the cost could not be better unless the bolts were free.
If I sheared 4 bolts a season ($2.00), it would take over 60 years to break even, not counting the few minutes to replace the shear pin.

They will typically be on the yoke that hooks to the tractor PTO. Several different styles are seen, you will need to look closely at the yoke and you should see the shear pin. They are typically just a standard bolt and nut.

The shear pin location on the King Kutter is the connection of the rear of the PTO shaft to the shaft of the gear box. Very easy to get to in the event of a sheared pin.
Not sure where they may be on others but likely in the same area.

Thanks for your help! We found where the pins go and will give the bolt idea a try first. The torque box may work well if the pins go flying too often.

Make sure that you get a bolt that fills the hole as a smaller bolt that has some slop will shear much more quickly. I run a 6' king kutter with a 75 horse tractor and it takes 1/2 inch bolts. I just use the bolt to drive out the piece left in the center shaft after aligning the holes, it doesnt usually bugger the threads much. then I put just a nut on and bugger the threads with the hammer to keep the nut on. Takes me 5 min at the most. I agree with 440, tryin to chop dirt is almost always how I shear one.

We found that one out the hard way

... It didn't even make it six feet before it sheared!
