Hello all. I am still new to tractors and diesel engines so please bear with me. I am at the end of my mowing season (only brush hog 3 pastures) so no winter use. These mowing's account for about 30~40 hours/year. The tractor is a JD 2040 3 cylinder diesel. I am debating whether to: (a) change out the current oil (still looks brand new when viewed on the dipstick) and filter, run for several minutes to circulate it within the engine, then new oil sits in the engine over the winter and it's ready to use in the Spring; (b) leave the current oil/filter in the engine over the winter and then warm up and change in the Spring; (c) since I don't put that many hours on the engine and the oil looks brand new perhaps change out the filter come Spring and use the current oil for one more season. Not an economic issue the cost of oil and a filter is FAR LESS expensive than any repair caused by NOT making the correct course of action. Thanks for your opinions and thoughts.
