I noticed while moving round bales that the P/D is slipping in high on my 185. Can stop the tractor with the brakes, low is holding fine for now at least. Further inquiry found the hydraulic fluid low. Filled it up, low again the next day, great. I assume the tractor will have to be split to fix the seals. My question is, are the two problems related? Would low fluid level cause the P/D to slip in high? This is a really nice original tractor that I depend on, want to fix it right.

| Check your pressure in both hi and low on the power director valve before you do anything else. If pressure is good then you know it’s in the power director itself probably broken plates are floating inside the power director or overheated them with lack of oil possibly |

| And yes a split is required to replace the seals You could run a hose out of the drains to both housings and equalize the oil levels to get by this has been discussed on this forum before. You have a great tractor probably my most favorite all around tractor |

| I would think for the Power Director pressure to be affected by a low oil level, your power steering would have been wonky too. Fill her up with oil and see what it does. Oil transfer (if there is any) will be worse in HIGH range. Oil transfer problem should have the transmission/differential somewhat overfull. |

I did the bypass hose deal on a 180 I had ran it another 25 years and then sold it about 5 years ago and its still going strong.
