Question for you orchard guys. Trying to lay out an orchard using Trimble 2050 monitor with RTK and a toolbar with disks as markers. We are laying out 20' rows running north and south. In those rows we will be marking 10' spacings for the trees. What is the correct way to make those 10' spacings? I know we will have to set the A-B lines running east-west every 10' but what is the correct way to make those lines perpendicular to the 20' rows? Thanks for the help.
