Wondering what the normal operating tempature for this unit is and how quick from starting cold it should reach high temp range? Reason I'm asking is other day had packing on diesel petcock leaking and noticed after feeding that diesel dripping on to Heat Exchanger (directly below sediment bowl) was smoking. Did little investigating and Heat exchanger and Hydra Drive Unit itself goes from a cold start to so warm you can't keep hand on it in about 1 to 1 1/2 min. Never noticed it getting this warm before but never really checked it either. Hydra Power Drive unit does seem to opperate properly in both Direct and In-direct Drive and always has. Shifts easily while moving with no noticable hesitation. Does not feel to be noticably slipping but I may be wrong. Wondering if this Tempature rise is abnormal and I need to investigate further or am I being paranoid. Manual does mention OPERATING TEMP TOO HIGH and gives 5 possible causes but doesn't mention what Too HIGH A TEMPATURE WOULD BE. Unit does not seem to loose fluid and does not smell or look burnt. Thanks Rocko.

Today's Featured Article - Madison's County - by Anthony West. Philip Madison has been a good friend of mine for quite some time. He has patiently suffered my incessant chit chat on the subject of tractors for longer than I care to remember, and on many occasions he has put himself out, dropped what ever it was he was doing, to come and lend a hand cranking handles, or loading a find onto a trailer. Although he himself has never actually owned or restored a tractor, he was always enthusiastic and always around helping with other peoples projects. ... [Read Article]
