I Fixed An Oil Leak On This Massey Ferguson 7720 Farm Tractor

A real-world repair job on a Massey Ferguson 7720 Dyna-VT with a severe hydraulic oil leak. The video walks through the full diagnosis-to-fix process: removing the wheel, draining and pulling both the AdBlue and diesel tanks to access a hidden oil pressure sensor that turned out to be only finger-tight with a worn bonded washer. Reassembly and a confirmed leak-free test are included. Best for owners or mechanics facing a similar access challenge on a large CVT tractor.
