I am looking for a used commercial lawn mower and I found a Hustler FASTRAK18 but it's only 44" and my lawn is about 1.75 acres. Is that way too small? It's in really good condition (a couple of summers of home use) and they only want $3,199 for it. The exact mower with more hours on it also for sale for $2199 at another loaction. My price range is about $3,000, but I'm reluctant to buy a residential mower so I'm looking for a used commercial. One of the problems is that they always have super high hours and I assume that they're being sold because they're about at the end their lives. Any help would be great. Thanks.
