Just some things kibbled out of styrene bits and pieces. The mowers are primarily sheet styrene with bent wire push bars and engines made from bits of sprue. The wheels are sliced styrene rods of various sizes. The shed is plain sheet styrene used for sign material at a local dept. store, scribed and shaped as needed. The roof is 400 grit sandpaper, cut into 3/16" strips and notched every 1/8". Bubba is a modified Micro Machines people. Thankfully, apartment living allows me to enjoy lawnmowers again.
