Garden time; need a tiller recommendation

For a garden that size you'll need a pretty big walk behind one with forward and reverse gears. Others wise you'll hate you tiller. Lowes doesn't carry what you need.

Kind of depends on the soil, how often you'll turn it over, adding compost, etc. If this is a once a year deal I'd just rent one but if you plan on turning over from season to season then I'd look at something around the size of a Husky DRT900. the tricky thing with power driven tillers is getting one that you can turn, most of the sub-$1000 - $1200 models are going to suck making tight turns until the soil is really worked. The positive to that is that same issue makes them really good for busting sod on a new garden.

i have the cub cadet RT 65. it is a good tiller the only issue i had with it is when i first i got it couldnt make it till right. like there was no power. then i figured out that there is a nut attached to a cable right by the handle. turned that a few times and it worked like a charm. the problem with the cub cadet tiller is that you cant get attachments i.e. row maker for it. you can with the troy bilt. i even called cub cadet and asked them if they sold any and was told no that i would have to get a troy bilt if i wanted one (apparently both of them are owned by the same company). i have 20 rows 50' long and had to borrow a neighbor's tiller to make my rows and now i owe him beans for this year pay him back.
