Farm Pro 2425 Muffler

shoehorny · Jun 10, 2009

Howdy!

This is my first post here....

I have one of these Farm Pro 2425 tractors for several years now. Every now and then, I will snag the muffler's long exhaust pipe on a low hanging tree branch. As a result, the muffler sheers off an inch or two above where it is bolted on to the pipe going to the manifold.

This happened to me earlier this season and I have since been riding around with this wayward muffler loosely wired on to keep it from completely falling off. I was going to replace it again, but the price for these mufflers is over $125 plus shipping!!! My question is, can I replace this muffler with a generic muffler that I can easily pick up at TSC for about $30? Or are there known issues?

Right now, I can't see how it can hurt. I've been driving along with a dangling muffler for several weeks now with no issues other than loud exhaut noises. The $30 TSC muffler is designed to be used for a tractor. It has the same width inlet pipe. The way the old muffler broke off, it left a small two inch nipple above where the muffler was mounted. I could clamp the $30 TSC muffler to this nipple with a U bolt and be done!

I am surprised the tractor runs without a muffler. I thought back pressure would be an issue, but it does not seem to effect performance at all. And, it is only slightly louder without the muffler as when it had a muffler!

Thanks!

Absolutely Mike. Even if it takes a reducer to mate the diameters, you won't hurt a thing. Even though I personally have no use for under-tractor exhaust, that's another option for you to consider. If the 90 degree elbow that comes off your manifold is of the 2 bolt or 4 bolt variety, just reverse it 180 degrees. That points the exhaust down, and gives you the option to engineer an exhaust path under the rear axle.

Thanks Greg!

I am not interested, at this time, in redirecting the exhaust under the tractor. I want a quick and easy and inexpensive way to replace the existing muffler. The muffler I got with the tractor broke shortly after I got the tractor and I was sent a replacement from the dealer. That one broke, and I was able to get a replacement on Ebay. Now that one broke and it seems all sellers who have them want a lot of $$ for them.

The FarmPro muffler looks to be a cheaply made unit. My latest muffler has rust all over it! I can't justify paying over $125 for a new one if there is acceptable alternative....

Is there any specifications I should look for in getting a replacement? There are several after market mufflers available at TSC, all costing a few dollars more or less than $30. Here is the one I was thinking of getting: Muffler International H 1 - 0235590 | Tractor Supply Company

I attached a picture below. This muffler was built for an International tractor, but it looks like it will fit on this FarmPro too.

Thanks!

If the pipe diameters are compatible - or can be made to mate - it will work just fine. But I caution you to buy a rain cap, or at least weld on an angled tip to keep as much rain as possible out of the stack

oh yeah!

I plan to get one with an angle (I believe they have them in stock too). I heard the caps rattle a lot.

Thanks again! I will try this mod soon and report back here.

Hi Mike,

Perhaps consider a "break away muffler" or connect it with flexable exhaust duct from an auto parts store so it just tilts and does not shear off every time you whack it. Have you considered cutting off the low branches you keep smacking into?

Tree strikes and the bent/cracked exhaust pipe is why I relocated mine going forward and down. I got lucky and did mine early enough that I was able to salvage the original muffler. It sure is nice not having it to worry about the exhaust while I am maneuvering the tractor around thru the trees. Especially when some of my attention is out back with what ever tool I have on the back. There are pics of how I did mine, and some other excellent suggestions in this thread about exhaust reconfiguration.

If you can turn it just 90 deg, you could aim it forward and tip down like many of the older smaller Kubotas. A compromise between under and up and avoid both problems.

Sorry, missed yours for some reason Ron. Don't want to step on an toes here.

Thanks for the replies guys!

Although I do plan to make some sort of mod to the exhaust direction, I really just wanted to know if it would be okay to use another type (other than Jinma) muffler on my 2425. Greg says it would be ok, so I am going to give it a try.

I do have a FEL on my tractor that provides little room upfront to put the muffler there, but I will tackle giving it a try later....

I have too many trees to cut away branches, and besides, the trees are worth more to me than the tractor! This last time the muffler got whacked I was actually brush hogging along about a mile long stretch of forsynthia bushs, and the bushs brushed up against the muffler a few times too many. i will also consider putting the flex pipe in line too, after I give the replacement a try. Right now, I just need something put in place fast and cheap!

Thanks again!

Hey guys!

I finally got around to replacing the damaged muffer on my FarmPro tractor! I picked up an after market Ford muffler from TSC for only $29.99. Here is a link showing the model info.: Muffler Ford, Mfg.# FO-14 - 0234756 | Tractor Supply Company

I cut the adapter off of the old muffler using a recipricating saw. I also cut off the tail pipe extension off of the top. I ground the edges down smooth with my bench grinder. I had about two inches on the adapter. The new muffler fit snuggly over it (2" diameter). I stuck the tail pipe into the top part of the muffler (1.5" diameter). I secured the cut off pieces with U-bolts, that I also purchased at TSC for about $2 each.

I tightened everything up and it works great! The muffler emits about as much noise as the old one did when it was new - no improvement, but nothing is taken away using the replacement.

It looks better than the old one did. It is made of aluminized steel. I plan to paint it black, when I get around to it. All of the parts are made in the USA!!!

As for costs, a replacement Jimna muffler would have cost me about $125 plus shipping. The TSC muffler costs me $29.99 + $4 for U bolts + tax.

Happy summer!
