    Default Bush Hog M446

    I have an 8 year old M446 on a NH TN65. The tractor sits a lot and only has 315 hrs on it, and the FEL was installed when new. All of a sudden the hoses going to the bucket pivoting cylinders are leaking at the crimp fitting. Is this to be expected ? Is my hydraulic pump now over pressure? a sticking pressure relief valve? or what? All ideas are welcome and I also wonder if anyone has any direct experience with this? Thanks, Rick

    I have a new problem with this loader ... It was working fine for an hour and then the bucket has a hard time pivoting. If i raise the loader to the top it will pivot easier but will stop and the hose move when it gets to a certain spot as though there is a restriction in the lines. The cylinders are not bent or damaged. Please give me some ideas. I wonder if it has leaked down and now is trying to run on air, but it seems abruptly it would not hit a stop as though restricted

    Got the tilt/roll working again by reseating one coupler that had loosened. Learned it was likely a coupler by reading other threads here. Still leaking so ordered 4 new hoses. Merry Christmas to all!
