My friend bent arrow got a set of atv discs for about 140 bucks from Northern Tool. I don't know what the shipping was but they weigh about 80#. He says they work just great. They are not real wide and have trays to add cement blocks for additional weight. The angle of the discs can be adjusted too. Most guys don't put in acres of food plots and much more than this is overkill. I have overkill and acres but not as much as farmhunter. Just got a turkey with a 10" beard in the ladino clover. terry
