YM 2000B

[ajmphoto]

I just purchased a 2000B with 1028hrs. All Seems good with it, but I am new with this type of machine. Any advice on what I should look for would be greatly appreciated.

She runs fine, starts great, but yesterday when brushhoggin' she did get hot, but i was probably running faster that I should have trying to beat the rain.

The person that sold me this tractor said it was 27hp, I know that is not true, as I estimated it to be around 20, does anyone know the actual HP, I could not find it anywhere.

Again your help is greatly appreciated.

20 hp provided to the PTO, that's how the Japanese rate tractors, since the primary application is to run a rototiller in the paddies.

The identical engine has a 24hp nameplate on the engine in the US version, YM240, which is essentially the same tractor that was marketed here by Yanmar around 1980 when they had their own dealers here. (The American custom is to rate crankshaft HP from a bare engine.)

Most of those need the radiator rodded out (after 30 years!) to perform properly. They are designed to run at full rated hp continuously without overheating. But first check to see if there is mowing chaff choking the outside of the radiator, by running a hose back to front over the entire area.

I own a Ym 1700B and I push that litle tractor pretty hard some times never had a problem I figure the operator will wear out long before that tractor if I ever buy another tractor it will be a Yanmar maybe just a little bigger

What exactly does this entail? Simply flushing or more than that?

Mine was freshly done when I bought the tractor.

As I understand it, a professional radiator shop removes the top and bottom tanks and literally shoves a rod through each passage to clean it.

If that kills the radiator then the next choice is a new radiator, about $250.

Harbor Freight sells a little infrared temperature sensor, $10 on sale, that could probably identify if there are large areas of the radiator with no water passing through. Or a professional mechanic would have a better one. That might be the first stage of diagnosis, after cleaning the exterior of the radiator's tubes and fins.

These tractors are designed to run at full rated output all day without overheating. So if it's hot, it needs maintenance to get it back to standard condition.
