    Default 9n 3pt won't raise when hot

    The 3pt. hitch on my 9n won't raise after it warms up. Fluid level is always maintained. I'd appreciate any ideas at all. I use the tractor daily and it has become a real problem. Thanks guys.

    If you have hyd. Oil in it try 80-90 or 90 wt.in hyd. System. Oil thins as it gets hot and metal expands and normaly those pumps have a good bit of wear.

    Pull the side plate and check the lift cylinder for leaks. That's most likely the problem.

    ditto what jerry said.

    PS.. hyd oil in that sump is a bad idea.. that oil lubes the trans and rear end.

    plain hyd oil is not suitable for those parts.

    a 90wt gl1/3 oil or a 80w90 gl4/5 with an MT1 rating and stating yellow metal safe is ok.

    DO check for leaks...

    easy to R&R the hyd cover and or the pump...
