Read articles →This is a hands-on seasonal maintenance video following Ryan as he swaps a John Deere 4020 from lighter winter oil to SAE 30 for summer work, draining the crankcase overnight, replacing the oil filter, and changing and bleeding the fuel filter with a hand pump. It covers bolt sizes, oil quantity (about three gallons for the larger later-model engine), and a warning about overtightening the fuel filter fitting. Useful for owners doing their own routine service on an older 4020.
