1956 Ferguson TO35 tractor gets transmission oil change Massey Ferguson TO35

This is a hands-on transmission and differential oil change on a 1956 Ferguson TO35, done before storing the tractor. It shows draining badly water-contaminated old oil, a discussion of why they're using 80W90 instead of GL4 gear oil (cost and availability reasoning), and a father-son conversation about parts availability, hypoid gear oil risks, and possible future water-absorbing filtration. No specs sheet or reassembly torque numbers, just real-world DIY servicing for owners facing similar corrosion issues.
