Junkman - Thanks for the update on TractorSmart and the LA723 manual. I guess I misunderstood the person I spoke to at TractorSmart, I thought he said he was directing his business to another online Kubota parts dealer. Anyhow the cylinder is listed on TractorSmart parts, $371.10 - ouch....
As for damage, the rod is bent, the end cap, which I presume is screwed on is broken. I will check with a hydraulic repair shop first.
Do most tractor dealers give you an option ie; have cylinders sent out for repair over a new cylinder?
