I despise working in the gravel,But it has to be done sometimes.I borrowd my cherry picker to a friend and got it back,It was sprung when I needed it next.Come to find out he used it on unlevel gravel and twisted it pretty good.Have to get a new one,now you have to have someone stand on the right side ot keep it from tipping over on good concrete.No longer safe or usable.DARN!!!!
