My dad is building his own tracked vehicle (im just helping). Bought 2 brand new 159 inch paddle tracks for it. We are using a t20 transmission and leaning towards probably using a liquid cooled kawasaki motor for it. It will be a 2 seater and have a full cab and a box. Cab and box will both flip up separately to acces the engine and transmission. There will only be 2 #60 chains on it so maintainence will be easy. Heres a pic of one of our track frames with a track on it. Need to pull the track back off and finish welding and put the rest of the bogie wheels back on. Also need to put idler wheels on the bottom of the top of the track to help hold it up.
