Just an update. I took the cowling off around the dashboard and found what I think is the Throttle position Sensor. Just to see what would happen, I took the tractor for a test drive with the Load Match Switch in the ON position. Of course it was jerking. While driving, I unplugged the Throttle Position Sensor. After a couple of seconds, the jerking stopped and the forward movement was as smooth as if I turned the Load Match Switch off. The computer started flashing a code Short...Short...Short...Long. I assume meaning Throttle Position Sensor Malfunction. My guess is when I unplugged the sensor the computer saw the input was no longer there and defaulted out and changed the drive operation to standard as if the Load Match Switch had been turned off. I know this does not prove the Throttle position Switch is bad, but that is all I have to go on right now. If you have any other thought as to what may be malfunctioning, I would appreciate you input.
Any other thoughts to my madness?
Thank you in advance. I do appreciate all your advice.

have a John Deere XUV 4 X 4 Diesel Gator.
The first few years the little Kawasaki engine performed flawlessly and the engine still starts and gives no trouble.
Then, the fan would kick on and the overheat warning light would come on followed by a loss of power and the engine dying until it cooled off. The next annual dealer service included their fix for the OVERHEATING PROBLEM. They changed the thermostat and replaced the water pump. That did not fix the problem. I took the machine back to them and the fix this time was: COULD NOT DUPLICATE THE PROBLEM.
After reading some on line fixes, I tried the air relief at the bolt behind the carburetor. This would help for about a week and then the problem would repeat even on a cold winter day. I tried several other John Deere dealers for a solution. The best they could come up with was there was air getting into the cooling system some way. I should look for a loose hose connection or leaking radiator. The Gator is parked on a cement slab and no leaking was ever detected. All of the hoses looked to be in great shape.
I finally found an old retired small engine repair mechanic and he guaranteed he would fix the problem for me. He did the usual air bleed at the engine (like I had done many times) and showed me how to tell of the water was circulating: “stand at the left front of the Gator with the hood open after the Gator has been warmed up. The with your hand facing forward slide you arm down until you can feel the bottom radiator hose”. If the hose is warm, the cooling fluid is circulating. If the hose is not warm then the water is not circulating. I figured the problem was fixed. But, the Gator overheated again as soon as I got it home. This overheating was occurring within a mile of travel.
When I talked to the shade tree mechanic again, he asked me if I was checking the cooling level by opening the radiator’s cap. I SAID YES. THAT IS YOUR PROBLEM HE SAID. EVERY TIME YOU OPEN THE RADIATOR TO LOOK IN, YOU LET IN A SLUG OF AIR. He suggested I buy a new radiator cap and once again bleed the air at the engine. Then NEVER OPEN THE RADIATOR CAP UNLESS YOU ARE CHANGING THE FLUID.

His approved method of checking the cooling fluid is to look at the overflow tank. Keep the fluid between the two lines and make sure the rubber transfer hose is not sticking to the bottom of the tank and preventing fluid from sucking back into the system from the overflow tank. I replace the radiator cap and once again bleed the air out of the system. I made sure the overflow tank was between the lines and the return line was an inch off of the bottom of the tank.

I HAVE HAD NO FURTHER PROBLEMS FOR THE LAST SIX MONTHS.

Crunch I had considered buying a 3ph core aerator to hire out as it can be used as for overseeding as well.

They are a bit pricey though, and homeowners do not really understand the benefits that well and need to be educated. Other issue is that the core aerator can and will cut dog invisible fences and irrigation lines, so you need a contract that does not hold you liable up front. That will probably turn off most customers....:(

I just joined the Pats Quick Hitch bandwagon. Works nicely on my debris blower and rake. I am waiting to see how it works on my 925lb 3pt snowblower. Will update this post when I try it out.

My guess is that it's an earlier version of what they now sell at the TS454 or 484. Perhaps even the TS504. See link below

I don't think planting over the field has any issues "EXCEPT" soil preparation. You would have to be very careful not to disturb the filters above the stone. Doing that would allow silt into the leach bed and that would cause some problems down the road.

Many places use all types of "FERTILIZER" including human, cow, horse and others. I think I'd like to at least see it composted for a year before I use it.

treeman, thanks for the link. So we know a diesel can run away using it's own fuel or another source from within the machine such as this one or another outside source I think we were told of like propane in the air. Think I am going to review ways to kill one.

I know the one I was around was a brand new start up in an OEM plant. Totally cold engine, using it's own fuel but throttle control locked fully open. But with an outside source of fuel is it more an issue with a hot engine? Or will diesels run fine on all those fuel sources at anytime?

Hi, am new to the forum, I have a 83 Belarus 900 which seems to be leaking water from a seal around 2 of the injectors.<br>

If anyone has any info on this or has experienced this before I would be greatful to hear from you.<br>

As an Aereo user I can attest to how good the service was. There is just nothing near to it. All of the Cable and Satellite online options are very limited or simply do not work at all or are hard to set up or are resource hogs.<br>

Aereo has a site that simplifies contacting your congressional representatives if you agree that this decision is a big step backward for the consumer.<br>

I love blue cheese. Unfortunately I don't each much cheese right now with my new diet. I eat whatever I want through breakfast and lunch, but only vegetables and fruits for dinner. Have dropped 25 lbs so far.

Check the boots around the shift levers for it seems they fail on the Long rather quickly. You may find you can turn a bucket upside over them to help. Dealer who sold my brother his Long is a friend of mine and he said you can drain the hyd oil and let it set and it will separate and the oil is fine to use.

The only way I see to widen it is to reverse the rims. Do you know another way? I haven't used the tractor to mow it yet, I was grading it with the back blade. I used the John Deere 345 to mow it. I've been trying to fix what Duke Energy tore up. I have a 150 ft. stretch I can't do. Duke is suppose to come back and fix it. Larry.

My tractor has a front end loader on it. The pipe on the left side of the housing goes forward and I belive it feeds the front end loader valve. Can this feed both front end loader and the 3 point hitch at the same time?
