Hate to disappoint you, your ride on lawn mower has very little in common with a "tractor".
I commend your enthusiasm - Since retiring 10 years ago, I also have become somewhat enthusiastic about older ride on mowers - current collection (all of which were donated):
- Husqvarna 22 hp
- Toro Wheel horse 14 & 17 hp
- Old metal bonnet Toro Wheel Horse 12 hp not yet going.
- Hustler Super Z repowered with new 23.5 hp Kawasaki
- Several donor units
All "non goers" when taken into care. For the most part, a good service gets them going again.
