I am not a commercial lawn mowing guy -but you never know I could be - I have 5 acres in a class A floodway and the grass grows real quick and thick - our property can also be very bumpy - it is not a suburban yard at all. For 14 mowing seasons I had a John Deere GT 275 Garden Tractor with a 48" mulching deck. When we closed on the place in 1997 I was under alot of pressure and needed a mower fast so I went to the local JD dealership. Now I have time and I can buy what I want like a ZTR - an option I did not have in 1997. I should also point out that I love cutting the grass - to me its fun. After some research I have narrowed it down to SCAG and EXMARK. I am going to buy a commercial unit just so I can have something rugged that will last me a long time - I have been know to bump into a tree or two when mowing. And I am also tired of large repair bills that I have gotten on the JD in the last three years. How in the world am I suppose to choose between SCAG or Exmark? I like them both and I am only allowed to buy one! And Advise?
