Additional Features-Re-covered the seat
-Outdoor carpet in foot area
-New paint all over
-utility trailer
-added a front lift mechanism for a plow. Requires removing the cutting deck.
-working to add 3-point hitch, possibly hydraulic.
Mostly just a fun project to tinker with. Always in progress. Now I have the mower deck working, I'd like to add a bag, and I'm working on a 3-point hitch for stuff.
