Mrs. Stoney Ridge wrenching the PTO Wood Chipper....broke my last sheer pin!!

Watch on YouTube

What happens here

The presenter drives the tractor with the attached chipper into a wooded area for its first test. Upon engaging the PTO (Power Take-Off) shaft, the chipper's shear pin breaks almost immediately. The presenter explains that the shear pin is a safety device designed to break under excessive torque, protecting the chipper and tractor from damage. He suspects the failure was due to engaging the PTO at too high an RPM or an incorrect angle of the PTO shaft. After replacing the first shear pin, a second one breaks quickly, reaffirming the need for proper operational adjustments and potentially a different type of shear protection (like a slip clutch). The video concludes with the need to acquire more shear pins for future use.

Goal: Conduct initial chipper operation and address safety mechanism failures.

where's ha well guys we got it all mounted up at first I thought that the lift pump or the lift on this thing wouldn't hold it up it weighs like i said somewhere in the neighborhood of 900 pounds maybe a touch more but it lifted it up just fine so now we got to put this massey ferguson 240 to the test again I think it's 41 PTO horsepower very very nice tractor only 900 hours on it we've got it up you got it up in the air we're going to put our hearing protection on I'm gonna go up here in the woods and we're going to throw a few sticks through it now it's pretty much all we're going to do today is just try it out make sure it works and then we'll have it ready to rock and roll as soon as the weather dries out enough for us to actually take the tractor off in the fields and off in this big mess that I have over here [Music] goes so as soon as we got up here we pulled the PTO shaft to engage a PTO shaft and this is what happened we broke the shear pin almost immediately on the PTO shaft it just snapped awesome so evidently I had the PTO shaft and a bind of some sort which isn't very cool you're gonna have to work on that hopefully I got some more shear pins I think I do so if you guys work with three-point equipment sometimes you have a slip clutch and sometimes you have a shear pin this setup has a shear pin I would totally prefer a slip clutch setup on this but it's there for a good reason I think my angle was too high when I turn on the PTO and that's what caused it so we'll start the PTO with this thing at a lower rpm I think I started it at too high an RPM and it just snapped that shear pin and my angle was a little bit off in case you don't know what a shear pin is it's just a bolt basically just a heavy-duty bolt that goes through a little setup here on the PTO shaft so we got it all tightened down guys essential tools for your tractor toolbox a nice pair of old crusty channellocks and a good adjustable wrench definitely handy to have in the tractor toolbox you guys have any other tips of things we should keep in our tractor toolbox let me know missus Stoney Ridge just learned about shear pins contact / our clutch in a jar pto is there are ppl spinning here broke it whoo that was our last shear pin it did snap that shear pin I'm gonna shut the tractor down and open up the hopper make sure nothing's bound up in there make sure I don't accidentally have something in there that might be holding it back stay tuned stay tuned for the next vlog sometimes…
