I think your JD salesman was uninformed when he said that "these Zero Turn machines are just for big open & flat lawn area. And not for all those trees and baby hills around the house and pond" having used and worked on several Zero Turn mowers (ZTRs) mainly Exmark and Huskvarna for a lawn care company as well as many "standard" mowers I would say that in close quarters and around trees a mid-mount ZTR will probably be faster and easier to use than a standard mower (ie: a B3030 or other front wheel steer tractor), a 4 wheel steer machine may be different, I haven't used a 4 wheel steer tractor, but a ZTR will essentially eliminate the need to have a pushmower to edge with, as long as the ZTR can fit in the spaces. I highly recommend Exmarks, and recommend NOT getting Huskvarnas, they are not very well engineered and are a PITA to work on.1. Are you guys saying that the Kubota B3030 and/or the John Deere 3220 are too small for me? I am shocked! For small I would consider the John Deere X749 Tractor. But some of you guys are recommending Zero Turn from Exmark and/or John Deere and/or Kubota? Why? Are they faster and more efficient than John Deere X749 Tractor with 4 wheel drive and 4 wheel steering, which would be great for mowing around the house and pond with all those trees? A salesperson at a John Deere/ Exmark dealership told me that these Zero Turn machines are just for big open & flat lawn area. And not for all those trees and baby hills around the house and pond. Was he mistaken? Did I misunderstand him? I am confused!
