Welcome back! Last week, Jake and I swapped a rebuilt engine into his 1972 4020 Powershift. 1972 was the last year for the 4020 which makes this quite a valuable tractor, especially since it is a powershift. Getting the right engine into the tractor and adding some rare M&W parts makes it that much cooler and valuable. Gramps has also been pecking away on his Steiger project and now has it in primer. Thanks for watching, and I'll see you next time!
