So for a while I've been wanting to build a pow'r pup tractor. Older plans call for using a Ford Model A axle and 3 speed transmission, however both are incredibly hard to get a hold of. I was thinking using a Ford 9" or 8.8" rear axle and a 3 speed with granny gear transmission (T18 or Sm465) and cut the axle to about 40" overall. One thing the plans never stated was doing steering brakes. I was thinking just using two master cylinders on 2 brake pedals and blocking off one of the lines on the master cylinder and just run one line to each brake. However I'm not 100% sure that would even work. Option 2 was to just run the emergency brake cables to the pedals instead of having hydraulic brakes, but I'm not sure if that would be effective enough.
Another option I thought of doing was using a Peerless 820 transaxle and just do 2 8" go kart disc brakes on the axles. However my plans for the tractor are using it for plowing a garden, discing/cultivating, snowplowing or front loader. I'm not sure how well that transaxle would hold up to any of those tasks. I'd like to stay with the more traditional design and use truck parts vs garden tractor parts.
I have a background in welding and have decent fabrication skills. I tend to over build things so they can hold up to abuse without trouble. Frame would be 2"x4"x10ga rectangle tubing. Cat 0 hydraulic 3 point hitch. Harbor Freight 420cc Predator engine with a GM 3 wire alternator.
