I used to work at Sears as a mower mechanic sometimes on the road and other times in the shop. Before that I worked at Suzuki Cycles and the shop closed down. I've had a couple of mechanic friends who wanted to start a shop but it just wasn't my thing really. Paperwork, permits, payroll, insurance, inventory, inspections, grumpy customers and such are not my forte' as they say. Even though I studied Business Management in college, I won't put up with the aggravation. I piddle around with small engines when I'm of a mind to for friends, neighbors, and an occasional friend of a friend. My rates are extremely generous! I don't even charge them except for parts and they insist on cramming money in my pocket. As far as a hobby I'm getting over that part as well. I've gathered up all my push mowers in one area and will soon move all the riders in one area, then start through thinning out the ones that can be repaired and sold, or scrapped. I currently refuse to bring in any more until I get rid of these. Hobby? I suppose you could call it that.
