generally speaking, if you're a diy'er or tinkerer go to the big box stores,if you want service, parts, and an informed owner/salesperson go to a 'good' dealership.good warranty matters(imo).only YOU know what you can accept ,tolerate,and handle between them.i run a toro s.p.mower for the small stuff,but there are other good brands.i run a jd 42" for the larger stuff,but there are other good brand tractors/ztr's as far as the larger machines go there are a lot of choices. your thoughts should be on handling obstacles in yard(for tight turning)also keep in mind another driver for the big mower should you not be able to cut for one reason or another, how are they going to handle it. Attatchment capabilities including winter time blowing. Room in the garage/shed to store it in. price. and fencing gates. see what the neighbors are cutting with and their satisfaction with what they cut with.happy hunting
