OUTSTANDING. This helped very much. Wish I would have seen this before going to Tractor Supply and just "shotgun" buying bolts, washers and the wrong type nut. GREAT INTEL THANKS.
I had my first bolt break on my rc2072 and this was very helpful. I looked at the bolt that broke on mine and it was an 8 based on the bolt strength you gave. I bought from a dealer so I hope its right. Thanks for this video.
agree. sheered my first bolt today and it was a gr8. reading the manual it's very confusing (typical of JD in my experience) where the gr8 bolt goes and where the shear bolt goes. the book looks like it's the same bolt so maybe it's a mistake. but shearing a gr8, wow.
Took some reading and understanding of what the manual was trying to say and some of the videos helped (but I really wanted technical data to confirm them). There are TWO methods to connect the PTO shaft to the implement(s); shear bolt or differential clutch system. the Differential clutch has the gr8 bolt while the shear bolt is obviously meant to shear under stress so is normally the gr2 variety. with each comes more information, but that is something folks (like me) need to understand so i thought i'd share.
Thanks for the video. Mine came with a grade 8 unfortunately from the dealership. Just sheared it for the first time after 2 years. Hopefully it is okay.
My rotary cutter, (brush hog) had a #8 bolt in for a shear bolt from the manufacturer. When I hit a stump the bold did not shear but the gears in the gear box were destroyed! Now I am going to use the softest bold I can find. BTW, instead of using a screwdriver to line the shaft up use a drift pin instead. It is round, tapered and will contact all surfaces equally, unlike a screwdriver.
My John Deere man says that around here, if you don't loosen the slip clutch up and let it clean up the rust, the clutch will rust up, not slip, and your shear bolt will shear.
Excellent Video! Pointed me straight to the issue and how to fix.Thanks!

I learned my lesson about shear pins. I buy Bush Hog rotary cutters with slip clutches. It’s a game changer.
Grade 2 for units with shear pin. Grade 8 for units with slip clutch. RC2072 and RC2048 included.
Great video. I appreciate your instructions and listing of the strengths of the various bolts.

That’s unfortunate, what kind of tractor was that?
I was reading about Hide Glue and decided to search for a video of how to do it, I'm glad I found you man good job!
Great video, Greg. Exactly my situation!
Very useful, i didn't know the type of bolts and strenghts based on markings, until i saw this. I'll look next time i buy one. Thank you!
Great video
Check to make sure your slip clutch isnt frozen, Should do it once a year.
Thanks for this video. Very helpful for first time tractor owner.
Thank you. Great video.
"rolling head pry bar", get an assortment as your budget can handle, they're handy as pockets.
What size is the shear pin? I can’t find that no mark face bolt ! Mine is a JD Lx5. Been to Lowes. Where did you get that? Thanks
Better way to do that, is to use a spud wrench instead of a screwdriver.
(doesn't invalidate your method, just easier.)
my pto shaft isn't lining up with the internal hole so i cant put the pin in. I have a yanmar yrc60
very helpful
Looks like your pto shaft has a slip clutch. Do you slip it purposely periodically. If it functions you shouldn't need a shear pin.
Frontier rotary cutters use a slip clutch and shear bolt.
My John Deere man says that around here, if you don't loosen the slip clutch up and let it clean up the rust, the clutch will rust up, not slip, and your shear bolt will shear.
The original shear bolt is a 1/2"X3.5" grade 8 bolt. Maybe it should be grade 2.
Grade 8 is what you should use for slip clutches. This guy has it wrong and is probably why he breaks so many or his slip clutch is broken.
