I purchased this 74 power king with a tractor style muffler. There have been some modifications to the hood sheet metal to accomodate for it. There is some areas of stress in the hood where the cut was made. There is also a hole in hood covered by a metal disc. I'm not sure what it was for.

1. Do you guys like this style?
2. Should I be concerned with hood modifications long term (breaking or further cracking)
3. How would I did this back to factory? New hood or welding metal?
4. Any other thoughts appreciated.

Matthew

That hood could easily be welded and put back to its factory look, I am not familiar with this tractor but the metal work is straight forward. Any auto body shop can do it if your not a body man yourself. It is all up to how you like it to look. Good luck.

Well, tractor is very pretty!  Stack needs to be chrome or stainless or something?  I bet first hole in hood was exit idea, then realized can't open it?  Most times many elbows are used to go down under hood and THEN up for stacks.  Pipes made to go down and out slightly to standard muffler is the usual set-up. They did have a one piece pipe, but bet can't find one of those any good now days. The slot in hood could have been little neater for sure. If you like stack, I wouldn't even fix it at this time. I don't think the metal is going to crack or break any more for long time. Hoods are on epay all the time, not hard to find. Most of them are banged up some in front from hitting things, it sticks out past tractor some. Just watch for long or short versions, get the right one.

Hi I'm not a fan of vertical exhaust to easy to hit a low branch or other unmovable object and break things and then you have exhaust blowing back in your face, but if that's what you like then stay with it, I guess if it were mine and vertical was to stay  I make a gusset to reinforce the cutout, simple would be to rivet it in place or it could be welded but that means paint repairs, I'll post a picture of how I plumbed my exhaust so you can see one way it can be done.

Did you get the governor problem resolved?

[Rocketcity]

I ordered another governor cross shaft and had it welded today. Hope to drop it off tomorrow. I'll keep you updated. Thanks for asking. Matthew

MNGB, where did you find your muffler? I managed to disassemble my exhaust yesterday. Actually it became very loose from the engine and came out as one piece. I am thinking of adding one like yours. Where did you find the fittings?

Good Morning, they are standard 1" pipe fitting you can get them at any hardware store etc, coming out of the engine is a 1" close nipple going to a 90 degree street elbow and then to a 45 degree regular elbow I used lock nuts to try to lock the fittings in place the muffler I got from TEW here's a link

Hi Matthew, I miss spoke the first elbow is a 90 degree street not a 45 degree.

MNGB, thanks for the info and pictures. My old exhaust was Apparantly barely hanging on. Maybe 2 threads were engaged from the steel pipe into the block. There lies my problem with redoing it. I purchased the supplies you gave me from yours and it seems like it would work. I may need to move my starter. I am going to have the guy that is fixing my governed cross shaft to look at it and see what he thinks. I tried to clean with a wire brush but still had problems getting it threaded past one of so revolution. I don't know whether some of the exhaust pipe that Brian Miller sells at gardentractorpullingtips.com would work. It bolts on. My holes for that look threaded but different sizes.

Hi I have a 1 inch pipe tap I use to clean the threads so a fitting can be screwed in more, maybe you can find a plumber or a machine shop that can run a tap in for you. the flange type exhaust should work also if it is formed / bent close enough to squeeze in past the hood brace/mount as for the flange holes I think that the Kohlers are all the same  but could be wrong.

[Rocketcity]

MNGB, is yours the 7 3/4 or 4 3/4 pipe length? Just wondering which one they sell will fit better. I'll check on that tap. Should be fairly easy. May get mechanic to look into it. If he can't them I'll tackle it. Matthew

Hi Matthew, if your asking about the muffler I have the longer one installed which is this one, this one.
