It’s not Good to be Angry at a Tractor

My John Deere problems continue.

I am trying not to be crabby about the unpleasantness of working on my John Deere 430. When you let yourself get crabby about every problem in life, the net result is that you are crabby a lot. Other than that, the impact is low. It doesn’t make things better in any noticeable way. It just assures that every time something bad happens, you will go into a bad mood.

Bad things are sure to happen, but bad moods are optional to a great extent, so the best thing is to try to opt out. You still have bad experiences, but at least you don’t have the additional burden of intense, prolonged annoyance.

When I was young, it really bothered me when other drivers refused to dim their headlights. They made it hard for me to see the road, and it’s also a little bit painful to be blasted with high beams. One day I realized most of the discomfort of high beams came from the fact that I stared into them. When I learned to look away from them, about 75% of the unpleasantness went away. That meant I, not other drivers, had been causing it. You have to train yourself not to focus on the things that cause you to feel bad.

While trying my best to avoid being crabby, I will tell about my latest John Deere problem.

After I installed the linked belt on my tractor’s alternator and water pump, I had to remove the mower deck. I had dropped a bolt on it. I used a magnetic tool, my hands, and a leaf blower to try to find it, but nothing worked. I didn’t want to remove the deck. I think the manual says it weighs 345 pounds, and while John Deere claims it’s a breeze to remove, the job is very unpleasant because of John Deere’s poor engineering.

I got the deck out, and once it was in full view, I noticed the tractor’s muffler, lying on top of it.

I investigated and learned a few things.

First, the muffler had a hole in it. I thought this was made by a numbskull…I mean a mechanic…who was trying to improve the muffler in some way. I now believe the cheap steel simply tore away from a mount, making a very nice rectangular hole.

Second thing…no clamp. If there ever had been a clamp on the muffler, it was long gone.

Third thing…the muffler had what looked like mounts on the side, and one had snapped off. The steel was very thick, so it had to be low-grade steel in order to do that. Another mount had a little object attached to it. I never figured out what that was, but I think it must be a fragment of a structure the muffler used to be bolted to.

I could not get the muffler back into the space from which it had fallen. Not sure what the problem was, but there was no putting it back.

Eventually, I started the tractor and drove it indoors, and I noticed that it was no louder than it had been when I bought it. I have always worn hearing protection when running the tractor above idle speed. It’s pretty loud. Because the loss of the muffler didn’t lower the noise level, I concluded that the muffler had never been attached. Not since I bought it.

I found out a new John Deere muffler, which is a can with two pipes sticking out of it, costs $256. You can get big mufflers for farm tractors for 50 bucks or less, so I kind of suspect John Deere is gouging just a little.

I also found out that the muffler is a weak point on the 430. They break and fall off a lot. If I blow $256 on a muffler and somehow manage to repair all the damaged bits that it attaches to, it may fall off a month later.

Because I’ve been running the tractor unmuffled for two years, I know I don’t really need a muffler. This engine supposedly doesn’t need back pressure in order to work right. I would like a muffler, however, because a little less noise would be nice, and it just seems less bubba-esque to have a muffler.

I found out it’s hard to come up with a new exhaust solution. No one has found an easy answer. The neatest solution I found was a car resonator. Some guy bought a foot-long resonator and attached it directly to the exhaust manifold on top of his engine. The manifold is on the right, and it points to the left, horizontally, behind the fan. He made a hole in the left side cover of the tractor and ran the resonator through it. He put a shiny tip on the end of the resonator, and it looks great.

The resonator is supported only at the end where it attaches to the manifold, but it’s so light, it isn’t going to snap anything. The guy who did the mod referred to the original muffler as a monstrosity.

I can do what he did, but I would have to cut my tractor’s side cover. I would also have to find or make an exhaust flange for the resonator. Square flanges for 1.5″ OD pipe, with 2″ bolt centers, appear to be nonexistent. I would have to weld the flange to the resonator, and I’m not a great welder. Welding thin metal is especially hard.

I came up with a new idea.

A company named Gibson makes pretty tips that go on the ends of exhaust pipes. They clamp on, so they’re easy to install. My muffler is gone, but I still have a 1.5″-OD pipe beside the engine, pointing straight down. I can put a Gibson tip on it and direct the exhaust out under the tractor. I can get a bent tip to make it go sort of sideways.

My exhaust pipe points down toward some heavy items. The pipe needs to be offset by about an inch. That’s not a problem. I bought a small stainless pipe elbow. I’ll fasten one end to the exhaust pipe and the other will go into the Gibson tip.

What about noise? I don’t care much, because I wear protection, but why not try?

I found baffles that go inside motorcycle exhausts. They’re wide at the ends and skinny in the middle. You push them into pipes skinny end first, and then you use screws to fasten the fat ends to the pipes.

I ordered a short baffle. I can’t fasten it to the end of a bent tip, but I can drop the entire thing into the tip from the tip’s upper end. I don’t have to fasten it to anything because the bend in the tip’s end makes it impossible for the baffle to fall out.

For less than $60, I should have an exhaust which directs gases away from the inside of the tractor and could conceivably make it possible to use the tractor without ear protection.

I just don’t know. Maybe it’s better to spend $256 plus shipping and spend hours fighting with a new muffler, only to have it snap off a month later. I mean, this is a John Deere! Modifying a John Deere with infidel parts is an outrage!

I think it will be fine. In fact, it would be fine if I did nothing at all to it.

The OEM muffler is a spark-arresting design. I had to read up on that. Diesels throw off a certain amount of hot material, and it can cause fires. Hmm…I live in a place where it rains a lot, and I’ve been using my non-spark-arresting tractor for two years without any problems. I think I can forget about sparks. If I sell it to someone who lives in Arizona, I’ll warn him.

They make spark-arresting screens for exhausts. I would have to figure out how to adapt one to my shopmade “muffler.” I’m not doing it today. Ain’t nobody got time for that.

My garden tractor problems have me thinking about a new machine. I can afford it. I know I don’t want John Deere. Other people say they’re hard to work on, and my own experience has been bad, so I am willing to take a chance on something else. Kubota makes garden tractors. They also make subcompact tractors which will mow. My understanding is that the subcompacts are so much better, you should buy one instead of a garden tractor if you can.

I could go for a zero turn (a phrase which makes no sense). They mow better, but having a second tractor is a great thing.

I talked diesel with my buddy Mike today, and he gave me a great idea. If I move to Tennessee, I should sell my Kubota tractor to someone here. I want a bigger tractor, so why pay a lot of money to ship this one and then sell it? I could sell the Kubota and John Deere down here and buy something else up north. Clean start. The Kubota has been fantastic, unlike the John Deere, but there are things you can’t do well with 37 horsepower.

Of course, I could put a finish mower on the Kubota and use it on my lawn. It would be clumsy, though, and I would need to follow up with something smaller.

I’m very happy with my muffler scheme. I don’t like dealing with John Deere at all, and the thought of paying $256 for a can really bothered me, especially when I considered the likelihood that it would fall apart quickly.

I think John Deere is like Snap-On and Mac. You get people addicted to a mythology, and then you can charge them whatever you want. I don’t have to have machines that are all one color in order to feel good about myself. That’s a sign of mental illness, not good judgment.
