Hello from the new kid on the John Deere 2305 block. Hope I do this posting correctly. I installed a 54" snow blade (hydraulic operation) on my 2305. Having never before removed the 54C mid-mount mower deck, I set about that task, since I didn't want the mower deck on the tractor over the winter while plowing snow. During the summer the rockshaft lever raised and lowered the mower deck and the three point hitch. While following the directions for removing the mower deck, the rockshaft lever would not raise or lower the mowing deck as it did in the summer, although it still worked fine with the three-point hitch. So the mower deck is still attached. Where to from here? Does it matter that I installed the plow before removing the mower deck? Any help would be greatly appreciated.
