I bought a CTL batwing mower that is about a 12 foot cut. 4 cylinder Kubota I think. It bucks so bad at full throttle that it almost throws me off. At about throttle it does better. I've only had it for one day and wonder if the decks are dragging or an adjust needs to be made? It doesn't seem like a good thing to run it at half throttle. Thank you[/ i believe the model is 4500d but i will update soon and pictures . I guess these are called wan mowers but it does not buck in reverse. Has a PTO front deck. The right side deck is weak after a few minutes
