Hi All, New to forum. I have a Carraro 3800 bi directional tractor. It is a fantastic bit of gear for general small farm operation. Just one issue, which is the temperature that the gauge runs at when pto engaged. I've been using a slasher in normal forward motion, and a finishing mower in reverse mode (so the mower is out front when operating). In both cases, as soon as there is a little bit of load on the drive, the temperature gauge runs up to just at the top of the green band, and occasional into the red. The overheat warning light has come on once or twice. When the gauge is right at the top of the green band, I can comfortably leave my hand on the radiator and also top of the engine without getting burnt, so I'm wondering whether it is just the parameters of the gauge. I've spoken to the local tractor mechanic and he indicated that the European tractors generally only have a radiator just big enough. The radiator is clean and I maintain it clean throughout operation. I'm in central NSW so it can get a bit hot, however have been operating it when the outside temperature is something between 10 to 20 degrees Has anyone else had experience with either the 3800 or its replacement the 4400 and the operating temperature. I'm just trying to work out whether there may be some problem (buggered bearing etc) in the direct drive PTO shaft that is meaning that the engine is under more pressure than when the tractor is just operating in hydrostatic mode. Any thoughts would be greatly appreciated.
