Mowing Knocking Sound with Mower

[Joe 7610]

A strange knocking sound started today. I have a Kubota B7610 that seemed fine until I attached the mower (a tow behind bush-hog). As soon as I started to pull out of the shed I could hear a loud knocking sound by the right rear wheel. It only knocks when the tractor is rolling, so I thought it might be related to bearings or something, and I decided not to mow. But, it's strange that it started when I attached the mower. I'd appreciate any thoughts about what might be wrong.

Check the wheel hub and make sure it's tight.

Not just the wheel but the hub on the axle! You have what they call adjustable hubs on the axle.
