Rain cap

[DeereJohn1]

Good Morning! I purchased a 720 LP a while back and would like to put a rain cap on it so I don't have to rely on the coffee can. Can you tell me the diameter of the exhaust pipe? I'd go look, but the tractor is still several hours away....Thanks

Get a vegetable can and use that, a rain cap on a 2 cylinder is noisy. Had to determine whose exhaust is on there to know the size. You have a farm supply store near by to measure a muffler on hand or look on this site as they may have size listed.

This site says 2 5/8 and steiner says 3-3 3/16.

Thanks all - I did notice not many have the rain caps - I can see how having the "pops" of exhaust would make those things really clank.

you dont put rain caps on 2 bangers. buy youself a can of tall tomatoe juice , then you have the exhaust pipe cover. perfect fit. all them 2 bangers use the same can, same muffler.

With the soup can you also get that neat, pop, bang when you forget to take it off and it blows off when you start the tractor.

Made this exhaust extension for a 730 I had. Worked good. Two cylinders don't work well with rain caps. Especially if you really make them work, They will just pound up and down.

Sorry about the double post. Made this exhaust extension for a 730 I had. Worked good. Two cylinders don't work well with rain caps. Especially if you really make them work, They will just pound up and down.

Dad used old coffee cans and took a 12" - 18" piece of soft copper pipe (back when such pipe didn't cost a mortgage payment for each 50"), pounded one end flat for about 3", and bolted the pipe to the can for a handle. Dad wasn't the tallest member of the family and the handle made putting the cans on easier. Yes: canS. One for the intake, too. Still have the pair he made for the '49 A. He painted one green and left the other to rust so I would know which was which.

If the exhaust is clanking you need to learn how to tune up your engine.

At an idle they will clank it goes away with a bit of throttle

Got one from tsc for my mf165 diesel. First hard pull it blew apart. Would think a 720 would even faster.

Really depends on what the muffler is ?? Could be the small A version round one or the large oval 30 series style muffler

I put one on my 420. Initially it did clank. After some thought I came up with a plan to "re-balance" it so the downward weight of the cap portion was lighter.

I drilled a hole in the vertical "vane" that is on the other side of the hinge from the cap portion. I put in a nut and a bolt as a counter weight and tested it at idle for clanking. I then added washers until the assembly was sufficiently balanced to stop clanking at idle. It worked really well.

We had a John Deere 40 Crawler that some how would accumulate gas vapors in the exhaust after it was shut off. We'd turn it off and put the can on the exhaust and walk away. When you were about 30 feet away, you'd hear a BANG. Turning around you'd see the can about 20 feet in the air. Then you'd have to walk back and put it back on.
