Massey Ferguson TO-35 Transmission Oil Change and Little Test Run

This is a hands-on DIY maintenance video from an owner prepping a 1955 Massey Ferguson TO-35 (called a 235 in the video) for tractor pulls. It walks through draining the shared transmission/rear-end/hydraulic system, discusses needing GL4-spec gear oil to protect brass gear coatings, shows the drained fluid and metal shavings, refills roughly 27-28 liters, and ends with a brief test run. Best for owners doing the same fluid service on an old TO-35.
