KUBOTA GRAND L3940 FULL SERVICE (tractor maintenance)

This is a hands-on, step-by-step full service of a Kubota L3940 that had sat in storage two years, done by the owner himself (part three of a series). He drains and refills HST/transmission fluid, swaps both HST filters, changes engine oil and oil filter, fuel filter, and air filter, showing old-vs-new parts and filter condition along the way. Good for owners wanting a real DIY maintenance walkthrough, not a buyer's review or spec rundown.
