Massey 1085 hydraulic filter - strainer


New User
Experiencing problems raising 3 pt.hitch and pto operation in freezing conditions. Worked OK in summer. Hydraulics are weak on startup but eventually build up enough pressure to raise and lower arms, operate attachments and pto operates normally. However, under load (snowblower extremes) the pto stops turning.
Drained the trans-hyd oil and recovered only 4 gallons of a required 8.5 gal.

Will filling to capacity help resolve this problem? I removed the triangular plate on the bottom looking for a screen or strainer but saw none. There doesn't seem to be an external filter for hydraulic oil. I was thinking there must be an access point for filter, screen or strainer cleaning but have no idea where to look.

Is there anyone that can provide some insight into accessing filters? presumably the hydraulic pump has a filter unit attached but it is not clear whether this can be accessed easily from the outside. I'm ordering a Service Manual but it may not show this level of detail.

Cab and dual fuel tanks make it difficult to reach all sides of the rear end.

I have no knowledge of the Massey 1085, but you can find a YouTube video.

The same fellow has several other videos on Massey 1085 hydraulic pressure.
There is a suction strainer filter listed, so it's there somewhere.

How does the oil look, any evidence of water?

A multi grade synthetic oil would help. On the older MF's slow hydraulics in cold weather was a problem.
Substituting 10w 30 engine oil worked better than the 90w mineral oil, but be sure before substituting
