FOURRR! Point!
You can also go on line with the brand and model number, and get a wiring schematic, or info on how to wire it, and trouble shoot the engine. But it sounds like what has been said already, will help you quite a bit. Oh, yeah, after the low wall tires, sparkly rims, and spinners, you can add the hydraulics, to make it a low rider, jumping cart, and you can call it La Bambi!
Camo of course is the only color for that, deer taxi.
The question is, which, real tree stye, Army digital, military desert, woodland, tree...... etc. So many choices. Well good luck with it, and I do think you can get it ready for next year, and show your benefactor, what he threw away.
Oooh, you could put an idler wheel on the frame on each side, and make cleats, and get some conveyor belt, and split it, bolt the cleats on it, and make it into a half track!! Just saying.....
