3pt an hydrulics along with steering are not working. I removed the suction screen and it was covered in what looked like big chunks of black sand. I put a new spin on filter on it along with the element filter. Still nothing. Any ideas ?

The park brake pad on my 2355 came loose from the brake band. Then little pieces of brake material and the rivets they were attached to went through the transmission and onto every valve seat in the machine. Causing erratic steering control, loss of loader functions, ect.

Those little pieces... after they had been chewed up in the transmission, to me, resemble what you describe as black sand.

Sold it.

Honestly, I completely flushed the transmission, replaced the steering box and hydraulic pump... twice each. The last time was by Deere.

No amount of flushing seemed to matter, it constantly ate the hydraulic valve seats. I was so fed up at that point I sold it for less than it was worth.

As luck would have it, he has had trouble free service from it as far as I know.

Which filter? The spin on or the cartrige filter?

Cartridge filter. Another thing you can try is install a hyd pump destroking screw and then manually destroke/engage pump to possibly clear debris from valve seating area. Do tractor have a FEL??
