Hope this post is allowed, as it is related to a non--Kubota implement, my BushHog 286 rotary mower. (I do have an M4900 Kubota Special Utility tractor that I pull the mower with). The rear tail wheel which support the mower has begun to ‘stick’ in a sideways position when I turn at the end of a mowing row. When it does this, it will plow up a furrow of grass and soil until I lift the deck and straighten the wheel. Needless to say, this is aggravating and time consuming. I keep the wheel lubed, and both the wheel itself and the swivel it’s mounted on seem to move freely when lifted from contact with the ground. This has just started happening recently, so looking for some advice as to what is causing this and how to remedy it. Thanks for any advice or help!
