My LX565 seems very prone to jerky backwards and forwards movements when working on bumpy uneven ground. Being new to skid steers and having only ever driven this one I don't know if this is normal? It seems to travel fine over smooth ground but it almost seems like when you do something to cause a bit of a bump, your arms get bumped on the levers and it ends up setting up a violent rocking motion like your sitting on a rocking chair. When this happens you have to stop and start off again. Is this something I need to practice my driving technique to fix?
