Wait, didn't we just have a very heated debate on mowers a few weeks ago?
Check out my thread in previous post. Z915B - 60" price was a ton less. Still has the Kohler vs Kawasaki, but it's been a beast.Commercial entry level both Kohlers, Z 915B--48"(7250) 54"($7450).
We went from 7 hours cutting with 46" deck yard tractors to about 2.5 hours with the fastrak. The very first time out we started at 9am and were done by noon. My wife and I looked at one another in disbelief, asking "what the hell are we gonna do for the rest of the day?". I kick myself in the ass for not buying one sooner.
I bought a 60" EXmark Z-line (commercial) with the 29 hp Fuel injected Kohler in 2012. Paid close to 12k, hurt like heck on the front side. Yard is about 4.5 acres. Takes 2.5-3 hours to mow it depending on the direction Im going. So far other than oil, filter and blades I have had zero problems with it. Today it has 606 hours on it.
Down side that I dont like is that I think it should cut better when the grass is tall. If its too tall the yard has to be cut twice to get the finish that I like.
We are moving to a house with a yard that is 50'x50' in a few weeks. Let me know if youre interested. lol
