Dave, Many old manuals will recommend kerosene or the like for flushing any fluid area....when flushing the crankcase, take the valve cover off and make sure that it is relatively clean. I have heard that if you flush a real gooey crankcase, you can open a hornets nest. Another alternative is to keep changing the oil [and **filter** - when changing the filter, make sure all of the parts are there--ie, top and bottom seals] with a lighter weight oil [don't over work/heat the engine too much] @ very frequent intervals...this will remove the heavier sediments and goo. At the first oil change, remove the oil pan and clean the bottom thoroughly [make sure you have another oil-pan gasket ready if the old one is toast]. If, under the valve cover is not too bad, then add 4/5 varsol and 1/5 engine flush to the crackcase. Just run the engine for about 5-7 minutes in a stationary position, then drain. For the transmission, replace the fluid with varsol minus the addition of one bottle of engine flush. Jack both [back] tires off the ground, secure tractor, start and slowly engage tractor in 1st gear @ low-mediun speeds for a couple of minutes [don't drive on ground]. This will help to circulate the solvent and free any goo. After you refill with proper fluid, clean the bottom of the tractors seal/gasket areas respective to the transmission to monitor for any future leakage...your next transmission change may come a little earlier than normal because not all of the older fluids were all removed with the flush...just gauge your usage to make the change...good luck tjs
