I know this is real long, but a lot of info here..
FYI, we have had Deere refuse warranty on a couple of front end repairs due to the following not being followed

ADDING BALLAST TO 3-POINT HITCH
Weight can be added to the ballast box by adding material such as sand, concrete, or portland cement. If more weight is required, tractor Quik-Tatch weights may be used. A ballast box extension is available to increase capacity of box. See Attachments section.
A 3-point-hitch-mounted implement may be used as ballast, but it must meet weight requirements of the ballast chart. See your John Deere dealer.
