Low Speed Vibration TYM 293?

[moveit]

My TYM 293 has developed a low speed vibration - Using 4 wheel drive doesn't seem to affect it - No vibration in High gear ?
The tractor has 240 hours and this is the first problem?

Any thoughts?

Looks like I may have found the problem - Steering ball joints were very loose - Tightened them and it seems fine !
