going in to get a bucket of rock and felt like i hit a wall then no hydraulics ,no smells,no leaks , engine runs fine any ideas
I don't know Deere machines but it sound like the coupler from the engine to the hyd. may have sheared.
Sounds like coupler as stated above .Did you lose machine movement also or just the hydraulics? There is a fiber coupler between the engine and the hydrosat pumps that fails. If you have a parts book or disk check it out will show you how things are put togather ,then start tracing things down.Good luck

Any chance that the seat belt sensor came loose? That will stop everything immediately. Just tossing up simple possibilities.
