I just bought a new MX5100 from the local Kubota dealer in Texarkana about 2 months ago. I'm seeking assistance here because if I take it in for service, it may take a month to get it back and I need it working now. Here's what happened. I was at the pond using the box blade to do some work. All of a sudden, the hydraulic lift handle quit working. It wouldn't raise or lower the blade. Thank goodness it quit working in the up position. My first action was to add fluid. I put about a half gallon in and let it warm up, nothing. Then I noticed on the lower portion of the arm where it goes into the transmission, there appeared to be a pin missing, so even though I was raising and lowering with the handle, it wasn't engaging because the pin fell out. I put a new pin in, now it raises and lowers just fine. BUT, now when I raise the box blade, it only clears the ground by a few inches. Is there a manual adjustment where I can raise the blade higher off the ground? I know it went much higher before the pin fell out. I've made all the adjustments possible on the 3 point hitch. Or, is this something the dealer should handle? Thanks for any advice.
