i am the proud owner of a new Massey-ferguson 1529 Hydro, and am due for the 50 hour service.The manual says to clean the Transmission filter(1 of 2) in "solvent or kerosene", so I was wondering what others used as a solvent......It also says to apply sealant to the threads on the drain plug, I'm guessing I can get that at any auto parts store..??......Thanks for any help....!!
