I got a question about a Kubota diesel tractor I use to cut the yard around here. I should preface it with the fact that most of the yard is hills and I cut with the contour as to not deliberately overheat the tractor. We've had it in the shop and checked out top to bottom and serviced. Since day one it'll overheat. The amount of yard we cut is about 5-6 acres. I'm wondering if we purchase and install an overflow tank similar to a car or truck if it'll cool any different. The reason I ask is when it does overheat which is every time we do cut it blows coolant out the overflow hose. That stuff costs more than diesel and is defiantly starting to add up. At present we're cutting every two days because of the growth.

I am sure not a diesel mech. but there has to be something wrong if it over heats. Is this an older unit? I sure would look for some type of restriction. Maybe calcium built up has plugged something. Not sure what moves the water thu the engine but maybe the impellers are worn. Just seems to me there is a mechanical problem

That's what I keep thinking. However, the mech's the landlord takes it to says everything is cool and there is nothing wrong. Their only other reply is that the property is too lage for the tractor itself. However, I can't find anything with more kick than 24 hp for it's size without going up to something like a full blown tractor.

Does it have rubber hoses like a car. Those things will collapse on the inside and not be noticeable. Plugged oil filter could cause problems.

The problem youre having with Kubota is one others are having, even down here on the flat prairies -- the radiator is undersized for the engine size. Have you tried, enlarging the radiators capacity with a bigger overflow-backup reservoir (common to most high preformance autos)? Prehaps changing the thermostat will help (coupled with the bigger overflow-reservoir?

When we had cotton pickers that would overheat, we would take the thermostat completely out. While most mechanics disagree with doing this on diesel engines, it worked for us.

At present it doesn't have an overflow tank at all. I tend to think the radiator is a bit undersized though as well. I saw an overflow tank kit at Wally World for $10 with all the hookups that I'm going to get in the next week and give a try with. The last time it was checked out it was serviced top to bottom and they couldn't find anything wrong with it. I'll ask the landlord about the thermostat since it's on his coin. The overflow though I don't see any harm in doing myself though.
