if you have good previouly turned ground without much vegitation i would think it would have good results. It looks like your doing a plot that has been disked reguraly and has some vegitation. But when i go to disk with my small tractor and disk with about 300lbs on it i have a good bit of trouble getting through the fall foodplot and what has grown in in the spring and early summer till i go to redisk it. glad it works for you.
Personally i would not want anything atv wise. First off i dont think my 300 would pull anything shy of a seeder or cultipacker, and also for the price of some of those atv disks i can buy half a tractor!!!
