New to the business not wanting to be full bore commercial and was wondering about the Bobcat ZTR's 52" with a 18 horse briggs. Is this a good mower and is this 18 horse engine enough to do the job? The mower can be had for $5000 plus tax. Any advise and/or suggestions welcome, I just can't spend much more than $5000 but want a commercial quality mower not the homowner versions, just mainly for my lawn and a few neighbors just to "justify" having such a mower. Thanks..
