Was reading posts about shredder shear pins.
Have Bush Hog RZ60 on a New Holland TC30.
One lot I mow is not unusual to go through 3 or 4 a day.
We have 5 acres last used as an ag chemical dealer yard. The ground is overall level, but with plenty of dips and humps. Cover is guinea grass, grows about 4 ft tall from clump bases. When the place was closed out 10 years ago the folks left small piles of junk around the back 3 acres. Since then the neighbors have added more stuff.
I learned about shear bolts when I first cranked the bush hog after the dealer installed it. I popped the clutch at the operating 5400rpm, and WHAM! Took me two days and a 40 mile trip to find a place that carries grade 2 bolts. I bought 3. No, I did not consider for more than 2 seconds using a standard grade 5 bolt.
I keep the FEL down to feel for trash when I mow this place. With the uneven ground and the clump bases of the grass there is much that slips by to the mower - pieces of 4x4, logs, old oil filters, trailer tires, balls of wire, chunks of concrete, old toaster oven, etc.
I carry a bag of shear bolts and tools in a 5 gal bucket on the shredder deck. I keep the shear bolt area (and other points) well greased.
After two passes, I about have most of the junk worked out of there. The other places I mow, level ground in bermuda grass and low weeds, are no problem.
The rear PTO of the TC30 is stiff to engage. Best way I found is let out the clutch (at idle power) till the gears start to engage. Then the lever moves easily.
BTW, that old ag chemical yard also had a berm 2-3 ft high and 120 ft long between the front and back sections, apparently buldozed up before the yard was closed to keep folks from driving across it. Chunks of railroad tie, tires, and other junk mixed in with the dirt and all overgrown with well established grass.
Taking down that berm was my first job when I got the TC30. There were some concrete pylons 15 inches square and 18 feet long built in there. Took all the power that little tractor has, but but it pulled them out after I had got them mostly dug free with the FEL.
