After retiring in '08 and taking life easy, I began using my knowledge and experience of working on motorcycles to apply to ztr's and any other mowers. Word spread around my rural community as a go-to guy for mower problems. Mostly the info was spread by my elderly uncle who relied on me to keep his Craftsman lawn tractor in good condition. My own ZTR is a 2007 Exmark 46" with a Kawasaki FH580V engine. Word spread around that I was the guy to see about engine tuning and maintenance so I began accepting mower maintenance and repair jobs as long as they didn't involve engine overhauls. In the spring of '18, a friend of my uncle contacted me about his Toro ZTR saying the engine was hard to start and was surging. He wanted a price to do the repair and, STUPID ME, I gave him my standard answer that he could pay for my labor for what he thought was fair. Big mistake on my part!!! So far, everyone I have fixed their mowers have been fair with me, but this guy only gave me $20 for my effort. I didn't complain since it was me who said I would accept whatever he thought was fair. He loaded his ZTR onto his trailer and left. At that time, I learned my lesson to never trust people to be fair and also that I wouldn't work on this guy's machine again. Wouldn't you know it? He called me today wanting me to replace a blade spindle. He was shocked when I quoted a price of $600 for labor UP FRONT and he would have to supply the parts. He exploded at the price and demanded to know why it was so high. I calmly explained that since he was so greedy the last time that I didn't give a damn about doing any work for him so take it or leave it.....CASH ONLY. He hung up on me. My uncle was shocked that his friend was damn cheap and said that I was justified. The guy is a deacon in the amen corner of the local Baptist Church. Go figure.
