So years ago I bought a terra tiger and it's been rotting away behind my parents house. It was full of water when I got it and in really bad shape so pretty much all the drive components are junk. So I'd like to start collecting parts to work on it one of these days. I would like to have reverse in it so I was thinking would it be possible to scrap a zero-turn mower and put the engine and drive Motors in this? I have a grasshopper zero turn and it seems pretty powerful. My biggest concern is weight as id like it to float on water again. Any input on this is appreciated.
