I had an idea about building a spreader/sprayer out of a ztr mower with a electric spreader and a 25 gal 9ft boom sprayer. My question is " What should I expect to pay for a used ztr? What is a reasonable amount of hours on a motor? I don't need the mower deck at all and would that be worth anything if I sold it? Yea, I'm too "frugal" to buy a $10,000 name brand.
