Well I had to search for the first set I got. Found and gave 50.00 for them. The second set I found and the guy said there yours. The third set came with the second tractor. Tractor, plow and cultivators 1200.00 for all. I guess If I had to work the 5 acers I do I would work a lot less than 5 acers. I've made my money on what I spent. Worth every dime I spent not to have to weed.
The three sets are completly different. One is bar style with sweeps. The second is round bars with sweeps. And the third set is springs. I really like the sweeps but both sets are missing one bar to complete them. And one set will not mate up with the other. I would make sure and check that you have six bars before taking them as they are proving hard to find.
Hope this helps.
