We were using an extremely heavy reverse rotation roto tiller (smities ground hog). Had machine picked up at full clearance , went to lower machine to ground, but checked roto tiller at 1/2 position, then lowered to groung. Now will not pick up roto tiller, remotes will not raise harrow. P/S works. Pto will not stay engaged. Changed filters. Piston pump high pres line pulsates as if starving for oil.Checked pres. relief spring on both pumps -ok intact. had to blow a seal or o-ring some where----any ideas?

Is the power steering running from the same pump?

No. There are 3 pumps stacked under the belly.

IIRC on the 7000 series tractors the 3 point and the remotes were on the second and third pumps, not on the same one. If your 3 point will not lift and the remotes will not work then my guess would be a pump drive issue. If you are interested, I think I still have a 7050 factory service manual down in the shop. (we used to be an AC dealer) PM me, and I will take a look if you would like.
