Re: Should I buy a Gravely 816T?
With a serial of 15896A that would mean the tractor does have an LSD axle. LSD's were no longer installed mid-way through the 73' MY, around the 18xxx serial.
On the axle hubs, the one set screw doesn't look to be a set screw, instead it appears to have been replaced by a common bolt. You'll want to replace that bolt witha proper set screw as bolt don't have the necessary properties to function as a set screw. Verify that both set screws are tight down on their axle keys, otherwise you'll wear out the key ways in the hubs. The in/out play of the rear axles is normal, and I wouldn't be concerned the separate play of the wheel in all directions. The bearings on the axles are very robust and bathed in oil.
