Disked about 7 acres with the 986 Wednesday morning, everything working fine till the last couple of rounds. Hyd telllite started flashing, steering was not good, spool valve would not lift up disc. Checked fluid level and was low. Added some fluid, appr 5 gal, level is just above full. Still had telllite on but only at idle. Changed filter this morning, fine metal shavings in screen and in filter housing. Added about 2 more gal of fluid, now above full mark. Telllite off at idle and everything working fine. Ran for about 30 min to add can of 134a. Drove tractor to park under shed, appr 1/4 mile and now have noise coming from rear end area and tellite on when less than 1500 rpm. Steering is not good when telllite on. Have I wiped one of the hyd pumps or is there possibly something going on in the rear end separate of the hydraulic problems I still have. I check the hyd oil cooler and it is clean. Thanks d sellers

Sounds like failure of bearing in transmission or final drive. I drain each plug separate to see which compartment has the bulk of the filings. Any time you get metal on the screen that tells you the filter is plugged and oil is going through the bypass screen valve. There are four different plugs to drain. Pump won't put enough crap in filter to plug it as it will quit pumping altogether before that.

Noise coming from rear end area only occurs when tractor is moving. No abnormal racket when not moving.
