I almost did it once but the dealer gave me a great price so I hired it out. It would be a snap for you. That is, assuming you took lots of pictures and started a separate thread on the repair. I've learned a lot from your repairs and the photos were excellent. The front bearing repair and tractor split for grease seal and clutch replacement should be required reading.

Do you have the links to both of those threads?

When I do the 3pt repair I'll link the other threads into that one. Thanks for the compliments Six.

I finally got things painted and put on the tractor last night. Aside from running it for less than a minute inside the barn, I have no idea if the sound has changed enough to suit me. Future testing required. I did find an exhaust leak I need to deal with at one of the slip joints I made.

Aside from that, and unrelated, I made up a set of rear tire chains, pieced together out of old semi truck chains I've picked up over the years. My OCD kicked in, and made me remove links from every cross bar so both sides match. (One side was 2 links wider than the other) That's alot of work.

If you don't have a chain tool it's aggravating work...

So are your chains now 2 link chains? Crossbar on every other link?

No chain tool, just hammer, cold chisel, bench vice, grinder and welder... what a pain in the @$$.

Nothing special, 3 open links between cross chains. Not bad for what it is. Better than nothing.

Had the tractor out to clean Horse stalls today... muffler mods helped the cackle a little, mostly tolerable noise level now... but an hour or two of brush hogging at WOT may tell another story. Will update as events happen.

This still surprises me. I thought adding pipe length would take care of some of the noise. But I also remember my teen years. You want a V-8 to sound cool?? Put the muffler as close to the engine as possible and then run pipes as long as possible.

I think we need a video to get a good appreciation for the sound.

It still this that 4 cylinder glass pack 'brrrAAPPPppp' at certain RPMs under light to mid load.

I'm with holding further feelings of dismay until I get a chance to really work it hard, brush hogging, etc. The combo of long and small diameter pipe at the end of the run is likely a major part of the cause.

Yeah, I think so too.

Brush hogged for about an hour this evening. The noise level is noticeable, but tolerable, for now. I'm going to just live with it, but may still add another 'muffler' towards the end of the last long straight sections. Having the end of the pipe less than 2' from my head, while pointed away, is still 'right there'!
