If you have any play anywhere, your axle bearings are going out. This is a very well known fault of JD tractors.
Tear it down, spend the money necessary to fix it and do not to neglect to grease your axle bearings every 100 hours. This is more than the JD manual says, but they are selling axle bearings.
