Hello to everyone. I'm new and I'm not in lawn service or landscaping business but I am interested in things such as lawn care. This looked like a good site so here I am. Right now I have a Tank M48, 48", 19 HP Kawasaki. I think it's a 2004. I seen some of the new Cub Cadet mowers like the Tank, Enforcer, and the Recon. Towards the end of the year I'm thinking of getting a new mower. Cub Cadet is the only ZT dealer in my area. I'm curious about some of the main differences in the Cub Cadet ZT series. I know the Tank I have is a pretty heavy mower. Are the Enforcers and Recons just smaller commercial mowers, or should I say lower in price? I don't mow for a living, just around my house and also my dad's house. The total is about 5 1/2 acres. I have the Commercial M48 now because some of the terrain is a little rough. There are some "hilly" areas also. I would like to have a little more HP also, I think my 265 pounds drag it down some. By the way, does anyone know the blade tip speed of the Tank M48, the one I have? Thanks.
