I like that picture of Ballistictip disc! There are quite a few old small 5' to 6' discs sitting around farms. You just have to keep your eyes open. Discs for ATV' s really don' t work well. They' re ok if the ground has already been broken (like a previously planted field).

You best off buying a small tractor disc. If you can' t get a local farmer to give you a hand using it, the next best thing is pulling it behind your 4x4 truck. It works very well.

The best place I' ve found to purchase small tractor discs is at Mills Fleet Farm. They sell a couple, one is King Kutter. These discs are roughly 6' and run from about $400 to $500 depending on the model. These units are built heavy, they' re not like the " toy 4 wheeler discs."

Good Luck!!
