50 hour service on a Badboy tractor

Overview

An owner walking through his own 50-hour service on a Bad Boy 5045H, with a useful side note that TYM 4820 parts are interchangeable, handy if you lack a local Bad Boy dealer. He covers engine oil, hydraulic fluid, front axle fluid, and air filter in a straightforward, no-frills format, notes all drain plugs are 17mm, and is upfront about skipping the fuel filter. Good for first-time 5045H owners planning this service.
