I put on the case board but no takers. My 4494 makes alot of hydraulic noise the last 2 times I've run it - specifically when I use the 3 pt hitch. These last 2 times have had a couple things in common - 1st is temp - about 30deg F - cold for normal use- I never warmed it up, just moving around yard - 2nd is the hydraulic oil level was about 5 gal over full - after draining down it has done it when run. Sounds like the pump is maxed out along with metal grinding only when hitch is raised- hitch raises fine everything operates good - remotes are stiff and powershift is slower - but they work ok and its colder - The guys who had it B4 me used lucas additive so it is thicker than hytran. Do I have a leak on my suction side of the pump where I'm sucking air, is the oil just that stiff - or is it time to send her packing. Gonna try new filters and oil first.
