Anyone got some useful information or advice? I am wanting to buy a cultivator as I'm doing more and more flowerbeds, sod jobs, etc. so I want to stop renting. The place I buy my equipment has an attachment cultivator for my stihl mm50 for $150. The also have the walk behind for $350. Is it worth the extra money? Also, are the troy-bilt cultivators crap that Lowe's sells? Rear or front tine better?
