Rick,
The general overall appearance can be a good indicator of the condition of the engine. The wear of the linkage on the brake and clutch along with the condition of the drawbar and three point mechanism indicate somewhat how the tractor has been used. New gaskets and sealants indicate that for some reason the tractor has been opened recently and you will want to know why. General leaking and spilled fluids and loose sheetmetal are evidence that the tractor has been neglected. Clean or obviously replaced filters throughout the tractor indicates that someone is trying to maintain and preserve the machine. If the tractor has been stored in the dry says a lot about the previous owners pride of owning the tractor. As for the engine, without test equipment there are still subtle indicators as to the overall condition. When the engine is cold see how readily it cranks. Above 40 degrees, it should start, without ether, almost immediately if the compression and timing are near factory original. The exhaust should clean up and any blue smoke should dissipate shortly. The black smoke that remains should not be dense and the exhaust should be nearly unobserveable once the engine comes to operating temperature. Observe the oil pressure and water temp during the starting period. The oil pressure should be on the high end of the gauge or above 40 lbs. and you should be able to observe the water temp rising and the thermostat eventually opening and the temp dropping somewhat. If you can work the tractor until everything comes to and operating temp it would be to your advantage. Once the engine has reached running temperature the oil pressure at idle should be in the 30 lbs. plus range. Anything below this indicates to me lots of hours and lots of wear. Cold weather can distort this reading and it can be high on a worn engine if the tractor is not worked hard for several hours. Never buy a tractor with low oil pressure or high water temp unless the price is adjusted to take care of the expense for correcting the problems. Rarely will you buy a tractor that does not need something. Spend enough time to identify its needs and pay only for what you are obviously are getting. Try to locate someone with some expertise and experience to accompany you to evaluate the potential purchase. Two inputs will reduce the chances of getting burned especially if one person has mechanical background.
