My second tractor was a two wheeler, my first had pedals. On the two wheeler, I used to remove all but two shanks from the cultivator and replace the sweeps with a short section of grader blade. As I remember, it moved precious little dirt because the blade was behind the wheels and pressing down on the handles to make it penetrate, tended to lift the wheels. They used to make dozer attachments for two wheelers and I've often wondered how well they worked. If I were you, I'd probably trade the two wheeler for a rider so your weight will be above the wheels and give better traction. Sorry to be discouraging but even my MF 261 won't dig very well with the bucket. One day, I might add a weight box and tooth bar and hope for the best. Good luck.
