Ok guys the build is complete. here are some specs:
original 1960 7hp model 19 briggs with adjusted governor- idles at 400 rpm and full throttle is about 4500
craftsman plastic fuel tank (stocker rusted out, and craftsman has more capacity)
5" rear pulley (9" stock)
locked differential by cleaning the grease off the parts in the stock external limited slip system and tightening the adjusters all the way (simplicity limited slip is adjustable by tightening two 7/16 bolts on the outside of the diff)
23x10.5x12 rear cut turf tires
16x4x8 carsle super lug ag front tires
go-cart steering wheel in place of missing stock one
simplicity dozer blade
wheelie bars and hitch for pulling
rototiller is attachable but runs off the same lift lever as the blade so it's not on at the moment
craftsman seat in place of stock missing seat
3" stack with rain cap
This tractor turned into more of a resto-mod than I first intended. I would have done bumpers but I hate to weld to this frame. I was just about to paint it but then decided that it looks cooler with the factory paint. Congrats to all who finished the build-off!
