What did I break?

[slim]

While running the brush hog, I hit a decent size rock. The unit on the shaft of my "Bush Hog-Squealer" broke where it attaches to the pto of the tractor.

What is that part? Is it difficult to replace my self? How much does it cost? Other than avoiding the rock, what can I do to avoid this again. I have 60 hours on my NH tc40da. I just back from 50 hour service at dealer. I have probably 10-15 hours on the brush hog. I did notice the pto shaft was dry compared to when I first hooked up brush hog. I don't know if that matters.

Could I get a replacement at TSC store or do I have to go to a dealer that handles Bush Hog?

As always, thanks for the help.

First, pull out you manual and read it!

If you do not have your manual, go to the Bush Hog website. There is an online manual here.

Without looking at your cutter, I'm guessing you broke a shear pin. This pin is designed to break if you hit an obstruction.
Replacement of this pin is described, in detail, on page 12 of the manual.

Since you write that's it's broken by the tractor, it could be the slip clutch which is also described in detail in your manual.

Once you have read your manual, you should be able to determine what the exact problem is and how to repair it.

If you still have questions...well, here we are...it'd be nice to have some pictures though...

You'll find that the great majority of any questions can be resolved by reading and understanding your manual

Welcome to TBN slim, any pics? I would think that you should have had a shear pin to keep this kind of thing from happening. Is the part that broke on the tractor end of the pto shaft? I'm hoping it wasn't the pto on the tractor that broke?

From the description, it sounds like you might have broke the yoke of the front u-joint. They're available seperately (instead of buying an entire pto shaft) But ask yourself why that part broke instead of the shear pin, if in fact you did break that yoke.

Heed Roy's GIANT message. Read and learn the info in the manual.

and, uh, Roy.... Am I going to need to wear a welding hood to buffer your posting from now on? LOL!

Roy,

Come on now, try and be a bit nice to the new guy. He has 3000 fewer posts than you, a new tractor and a new cutter. Having that shiny new expensive equipment fail is scary. (Reading your BIG post is scarier...)

I don't know about being nice, but you sure did make me laugh!

Good job!

I'm still waiting to find out what broke. From the info in the otiginal post could be anything from some ORC, to a yoke.. to a slip clutch.....

This is deffinately one of those times when a pic is worth 1k-words

Welcome to TBN ! Sorry about your RC from your described location of break I would tend to agree with Farmwithjunk (who really does not farm with junk ) and say it is the front u-joint yoke or maybe, but highly unlikely you have what I think is described as a radial pin slip clutch. I also agree with RoyJackson and suggest that you read your manual (His font play is new and disturbing to some of the old TBNtimers ). BTDT's suggestion for pictures would be helpful to the readership. John Bud and tuolumne exhibit the colleagiality (I think it is spelled right?) of the TBN membership. I will agree that breaking parts is scary and I would like to assure you that all of us TBN'ers (at least the honest ones ) will admit to a tractor learning curve (myself especially). Keep us posted- Jay

 

[RoyJackson]

Oh, like I don't exhibit the collegiality like those other guys?

I just use the font to emphasize something of value.

 

[slim]

It looks like I broke the yoke? (See pictures). If this is what I did, is it an easy fix? If the shear bolt goes through the yoke, I wonder why it didn't...shear? It wasn't really that BIG of a rock.

Thanks,
Slim

Yep that'd be the yoke. Looks like the yoke's on you. ( well someone had to say it.) Try a local drive line shop, they may be cheapest, or Agrisupply.com for a whole new driveshaft. Question is why did the $100.00 part break to save the $0.50 shear pin?

I look forward to all of your posts. You are quite informational as well as intertaining. Sorry if there was an implication of you not being colleagial (You even agree with me on occassion ). Jay

It was posted in a humorous vein, J...now I have to start using smilies too

WOW, the Yoke broke...and a bad pun too! (Thanks, Dave...that was pretty good)

Well, that's not too bad to replace...and Dave has a really good question...why didn't the shear pin go first? I suggest you replace the shear pin. It may have too tough a bolt through there.

And...for Jbrumberg...

No jokes about broke yokes blokes., ('er is that bloaks?)

Who was it that posted a picture of a broken yoke on a tiller just recently? Seems it was a defect in the casting. Even with a slip clutch or shear bolt, a BAD part may let go first.

I agree, while buying a new yoke you should get a hand-full of softer shear pins. I'd like to see what was used. Check the pin and see if it's a hardened bolt.. ie: what marks if any are on the head? it is possible the yoke had a previous damaging encounter with a bigger rock.. perhaps was cracked already? see if has any old rust in new break..

Roy glad you're around , always found your posts helpful and nice..

No you had it right ( I think ), bloke...

2 things may have been the root cause. The shear bolt was too hard. Grade 8 used where grade 2 or should have been used. OR the slip clutch was rusted up tight and could not slip.

Can you please post a picture of the part that attaches to the mower? I would like to see if it was a slip clutch.
