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.
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.
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.
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.
