After the demise of my LA155 JD mower, I decided to look at zero turn mowers. After checking out Hustler, Exmark, Cub Cadets, John Deere, Gravely and Bush Hog, I decided to get a 61" Bush Hog professional grade zero turn mower. I've used it 3 times now and, in spite my slowness moving along the learning curve, really have been pleased with it. The dealer included the first service free, a mulching kit installed and a set of mulching blades also installed.
You can see by one picture I'm also using it to trim some of my wife's bushes / trees.
So far I've managed to stay out of the flower bed. Saying that may have just jinxed me.
