Exhaust

Recommended Posts

bsggsb
Another question.... My Big Ten has the straight pipe exhaust to a small round muffler. My Simplicity 7014S has the exhaust in the same area of the tractor but it turns and goes inside the hood to a muffler and then comes back out. This of course generates a great deal of heat under the hood. Is there some reason anyone knows why I couldn't just put a muffler on that comes straight out like the B series had? I didn't know if it was an engineered back bressure issue or if they just decided to be cute. Thanks!

I'm guessin' the 7014 is a notable bit quitier then the Big Ten, though I've never heard on run, think that was the reason for the change in muffler design systems. Changes like that are often brought on by the need to keep up with the compition also,,looks etc...

I believe that the mufflers were mounted in front of the engine starting with the 3300 seies in 1971. Note that these tractors were a bit longer that the B series but that the length was added to the front of the frame. That allowed the front PTO to be enclosed and left room for the muffler in front of the engine. The engine cooling air flow should blow across the muffler after it exits the engine shrouding.

My grandad had a 3212V I think it was with outside exhaust. He pulled up outside the house one day and shut it off and before anyone could move my brother who was 6 or so years old at the time layed his hand on it...( solid second degree palm, fingers and all. This is the only real reason I can think of for putting all that heat under the hood.. But kids are a good one. Check out the prices on the Briggs "Low tone" mufflers. They have a great sound with out the "Tin horn" sound some have.. Hmmm thought just hit me.. A basket made of expanded metal around an outside exhaust would be great for people with kids...

ok...this is where I show my ingorance... My 7014S has the front PTO inside the hood area unlike the B series. Is there a mule system of pulleys to run a snowblower from that pto or does it use the same one as the mower. My dad has a Soverign and his blower uses the mower PTO and a REALLY long belt. If this is so, is there anything that uses the from PTO since it was enclosed?

My 3410 had the underhood muffler,that rusted out.When I changed the engine to a newer 11HP Briggs,I was going to use an original style underhood muffler,until I heard the price from the dealer.It was in the $75.00 range I think. I went to a pipe nipple,street el,and a round can type muffler,which exits just in front of the carb. Less than $20.00 for everything.Works great!

I also have a 7014s and for a very short time I ran a 12 horse out of a 3112 and used the original straght out muffler and it looked fine. I do like the quieter muffler as i get older. Now I even wear headphones when mowing. I remember a few years ago I think Al Eden said years ago he cut lawns all day with a muffler that came apart early in the day and damaged his ears. Kind of a wake up call for me.

My 3212 has a straight out muffler. I was pulling the cart Friday with my son. When I stopped to put some brush in the cart, he got down and ran up and put his hand on the muffler. Blistered 3 of his fingers. Didnt get his palm. Dont know why he did it, but I bet he wont do it again. My 3416 has the muffler under the hood. It is a lot safer, and quieter. Ive thought about putting a straight 'tractor' muffler on the 3212. Ive seen a couple and kind of like the looks. ddh ddh

Ya gotta watch those darned kids every minute!!! I had rigged a Wheel Horse blow on the front of my Ford. It was giving me fits with the first snow. The drive belt came off for the final time. As I was gathering the belt out of the way I layed my hand, hard, on that shiney stainless steel muffler. Yup, awsome blisters, palm, fingers and wrist. Yup, keep an eye on those kids.......

The four strokes are simple, to get more air and fuel in.....you have to get the exhaust out. Two strokes use the exh. backpressure to prevent the air/fuel mixture from leaving the combustion chamber and or mix the incoming charge...depending on design. Any good muffler made for your approximate horsepower should do.

oh yeah, for my big ten I bought a simplicity OEM muffler (the can that jets the exhaust 90 degrees out of the can) and welded a pipe nipple in the hole (this hurt since it was a new muffler) then I got an exhaust pipe for a Kubota b5200 with the curved end to clamp on the nipple, it looks cool. I will post a pic of the last progress on my big ten.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul
