Need some good ideas!  next week we want to pick up a bunch of rocks in a 200 acre soybean field.  30”rows.  Want to drive the tractor and have 2-3 neighbor kids helping me pick up rocks.  

I have a tractor w/ loader but not sure best way to have the boys tag along.  any pics of homemade toolbar with seats?.     or anybody know of a dump trailer that i could pull that would track between the rows?   I have some flatbed wagons but not sure if they would track, and if we’d put rocks on there, i couldn’t dump.   ideally i’d pull a dump trailer with low sides that would also track between the rows.

Any pics or ideas??
