Additional FeaturesHas lights, horn, no mower deck.

Spent some time over 1 winter cleaned painted and put this thing together.
Tried 3 or 4 different configurations ended up with what you see.
Motor spins the wrong way and is not reversible so I put a twist in the drive belt (figure 8) to get the right rotation for the trans axle. Found that grounding the field terminal gave me lower motor speed (2sp)

This is more of a kids toy than a riding mower, I do use it to pull a trailer for yard clean ups.

Best thing about this is jump on, turn the key, pick a gear, step on the foot switch and go.
