It currently takes me 1-1.5 hrs. to mow my lawn with a 21" mower depending on mulching or bagging. I would like to cut this time down if possible. I have 40" side gates on my fence. I am looking at getting a homeowner ztr. Either the dixon 3304 or the gravely 1232. Any thoughts on these machines? Which is better built, provides a better mulch cut and bagged cut. Ease of operation, etc. Thanks for the help.
