I currently have a 48 inch Exmark Turf Tracer and two Exmark Commercial 21s. While they get the job done on my smaller properties, my larger yard (Half Acre Plus) need a mower that can get the job done quicker. I was looking at two 60/61 inch ZTRs, the Toro Z Master 3000 series and and the Scag Tiger Cat, and I would like some feed back on cut quality, comfort, speed, durability and also the pricing of each unit. My knowledge on Zero Turns is limited so I apologize for my lack of knowledge about what I want. I did demo a Hustler X One and I did like the unit. Very fast and felt like it was built well. I have little experience with it in the field, but if any one has how are they holding up for you?
