Currently I am using el junko Troybilt with a B&S engine from Lowes to mow 2 acres. Mostly flat with some trees but have about 1/4 acre of rough area. Takes about 3 hours to mow. My general thought this is too long for me to be on a mower once sometimes twice a week. I think its time for an upgrade and plus I managed to talk the wife into an upgrade as well. Here is what I am thinking. Husqvarna MZ 6128- Looked at dealer yesterday. A lot of bang for the buck, but concerned about the Briggs and Stratton. Thinking about the 5225 cause it has the Kawasaki on it. Dealer thought the Briggs was easier to work on. Gravely ZT HD 60- Seems nice. Comes with Kawasaki. Exmark Pioneer S 60- liked it but price is more that I want to pay. Considering the following (have not went to these dealers yet) Toro Titan zx6020 BobCat FastCat Pro 61 Hustler Fastrak Super Duty 60 in with Kawasaki Your thoughts and opinions?
