John Deere 737 Z Track I have been in the market for awhile now for a new zero-turn mower. I have about 3.5 - 4 acres that I mow. Besides that, I take care of three other yards, along with the lawn around my dad's business. I want to know if the price that I have been quoted by my local JD dealer is a good price or not. What I am looking at is a John Deere 737 Z-Track w/ a 23 horse Kaw. engine, 54 in. deck. They have quoted me $6700. Also, if this is just a starting point, what should I try to work them down to? Lastly, will this mower be a quality mower for doing all of this work? Thanks for the help that anyone can give me.
