I have a new customer - an older gentleman - asked me to mow his yard. He didn't ask for a price, he wanted me to mow it. He gave me detailed instructions on how he wanted it done. No big deal, I've dealt with people like that before. I figure it's easier if I know what they want before I begin. He's watching me mow on my ZTR & he asked me to bag the grass for the first mowing only. He keeps stopping me while I'm working & saying that I am going too fast. A 1/2 acre lot, it takes me one hour & five minutes to cut at his preferred speed. My helper passed me twice as he walked behind the 21" trimming mower. He seems like a good guy, but . . . . I'm trying to convince him that the mower cuts just as well at it's designed operating speed. I'm loosing my patience with people and it's only April. I picked a heck of a time to quit drinking. Is it possible to attach a cane or aluminum walker to a ZTR?
