Slip clutch vs shear pin for bush hog

[coobie]

Well I ask for opinions on shear pins vs clutches and it turns into 8" trees. Wtf?

Funny stuff,huh??My preference is sheer pin.

Related actually. When a shear pin gives its gone ... and each shearing damages the shear zone some. A clutch on the tight side will just creep a bit with each blade impact when its chopping a tree, cinderblock, etc. It might "slip" a couple revolutions at the same torque that shears the bolt. You would get tired changing bolts and the clutch would be done with the tree and barely warm.

I'm waiting on 8" tree Youtube brush hog videos :thumbsup:

If you have time I would love to see a video of that bad boy in action.Love the old stout equipment.

Much as Id like to its been ~ 30yrs and the parts of the assembly have migrated and/or are used otherwise. A substantial reset cycle. Time conflicts are the issue - and its a job thats done and I dont have a need to repeat it. The JD has a postpounder and serves double duty on the hay elevator. The bushog has an easy life of unbderpowered use on the Kub Ls and the B9200.

Iv moved on from that episode. Time is not trivial when youve already got plenty to do that is critical to everyday life on the farm. -- Today Iv got to get up hay and core aerate and overseed the field.

Hey Spyderlk,
Don't let the critics get to you. Seasoned farmers do things they don't know they are not supposed to be able to do. There was a farmer around me that used to clear small "woods" with a rotary cutter. He tore stuff up a lot driving over trees and slowly letting the weight of the tractor bend them over, but that never stopped him.

Yeah, Im not offended by the doubters. They just havnt had this cutter nor used it in the setup I contrived. The JD 127 has a very strong gearbox on a lightweight chassis made with good steel. It doesnt take many mistakes to begin tearing up the underside on the body tho because it has all bracing exposed to the cut material that is being whipped around down there. I find them at auction with the body torn up and trans always fine. Last one I bought for $100 with a body so bad I just stored the gearbox as spare and turned the body into a counterweight. The body must be selectively braced to avoid tearing it up with what that gearbox will accomodate. Right off you add about 30# of steel where its needed and you have a very tuf 5' package with a 100+HP gearbox and a great slipclutch. As delivered the bushog is rated for 4" oak -- backing up. The compressive loading on the chassis is terribly abusive even at that size. Going forward 4" is trivial when youre driving with ~10HP per foot width.

My impression as a teenager when Dad bought it was that JD made it as a Bush Hog beater. It did. I dont know why they didnt just refine the chassis. Theres no 600# cutter around today with a quarter its capability. :confused3:

I like the slip clutch on the roto-tiller(service every year) but shear pins on the BH.I have only broke a couple in the 8 years I have owned it.Very easy to change,at least on my Bush-Hog branded BH.

I was trying to be "correct" but that was funny. :laughing:
