My 3 cyl diesel seems to bogg down after 30-45 min. of having a tiller or brush hog working behind it. The temp guage gets up to 3/4 and when i hit a spot that puts a load on the diesel it doesn't recover. The rpm's go down to 500-1000 or it stops altogether. When i run the loader or box blade the temp guage stays around 1/2. I don't know it that has anything to do with it. The guy I bought it from seems to think it's water in the fuel. What's your opinion. We both want to know, and i want it fixed. Thanks, Tod.

Let me preface this by saying I am no expert, but not sure how water in your fuel would cause you to overheat. It would cause your tractor to not run if there were enough water. Have you gone over the cooling system thoroughly? Checked the coolant, radiator cap, belts, water pump, is the radiator unobstructed and etc.. By the way, I own an E2304 so sort of curious to hear what turns up.

Tod, I don't have a Hinomoto, but I had similar problems with my New Holland. Water I doubt too. You should see it in your filter bowl if it was. It could be that you have a part in the governor which when heated by hard work like you are doing with the brush hog, gets tight and doesn't want to move freely. Secondly, the unit may have injectors that are sticking somewhat. Do you have any fuel knock? Are you using an cleaner or additive with lubrication? Finally, have you checked the output of the electric fuel pump which feeds the injector pump when hot? Could be that it is not working properly. If you have one, as I really don't know your machine, they generally start and stop to maintain a given pressure. Believe it or not, all of those things were in combination for my problem. Was a real pain to figure out what was wrong. Took almost two years, and a lot of frustration. One other thing may be something expanding and letting in air, but that sounds remote. Does it restart easily?? Good luck with your problem. Hope the post helps! Bill ....

As a tractor dealer this clearly looks like a case of overheating to me. Overheating a diesel will very often cause RPMs to drop. Water in the fuel no way. A tractor that is worked hard for a period and then backed off should quickly (5-10) minutes recover to normal temperature levels. If this doesn't happen the cooling system is compromised in some way. Plugged radiator either internal or external, blown head gasket, or a cracked head. Loader work and box blade work generally provides very little load so will not generate excessive engine heat. A Bush Hog or Finish mower in tall grass in a high gear is a good way to load a compact for a period of time if a tractor dyno is not available. You need to get to the bottom of this before the weather gets real hot. ....

Thanks for the info. I did drain out most of the antifreeze that was in the system and replaced it with straight water. The color looks about 5-10% antifreexe to water now. I was told this will let it run cooler. It did. I ran the brush hog for about 1 1/2 hours and the temp guage just barely got past the half way mark and never did bogg down and die or even try to. I opened the cooling system to make sure the thermostat was opening and water was circulating. How would I tell if it has a blown head gasket or cracked block. I remember something about water in the oil but it's been a long time ago since I works on old engines. Thanks for your help!!! Tod. ....

Bill, thanks for the tip. I hope it doesn't come to that. I think dropping the antifreeze mixture helped a bunch. I'll find out tomorrow when I have to hook up the tiller again. Thanks, Tod. ....

Make sure there are no obstructions in front of the radiator also run a pressure washer or some compressed air across the fins to make sure these are clean a regular water hose doesnt have enough pressure. If a head gasket is leaking it will show up as air bubbles when the tractor is running. To check for proper t-stat operation start with the engine cold and check for flow in the radiator there should be none. Next after the engine has warmed up some you should see antifreeze flow. One important item if there was to much antifreeze in the system it could cause it to overheat, antifreeze can't despell the heat like water can but remember with no antifreeze in the system--you will end up with a big ball of rust and more problems down the road.
Clean the fins first you might be surprized how much that helps. ....
