http://www.youtube.com/watch?v=OprEAY19eo0 While out mowing today I noticed the castor wheel on the front left would not spin real good. When I got home I jacked it up and took the wheel off the yoke and noticed allot of play in it as you can see in the vid. The other side is tight as can be and I dont even know how to take the yoke off to see what has happened. The only thing I have done is greased them a week ago and they had not been greased in some time please let me know what has happened. Thanks Also the whole arm moves that the castor is on because it pivots and can put a pin in so it cant pivot this is a lesco ztwo.
