looking at a lesco hydro walkbehind with around 4 to 500 hours on it. it has a 48 in. deck, 17 hp kawasaki, 4 sets of blades, a sulky and a collection system with a 5 hp briggs. he said he was asking 2500.00 for it but he would sell it for 2000.00. it needs a good wash but otherwise it looks pretty clean and well taken care of. does this price sound right. also would this be a good mower to start out with. any help would ba appreciated thank's ahead of time.
