To tractor pimp
The group is looking over the problem and has asked a few questions. what is needed is for you to describe all the conditions that are going on with the tractor. The other members wil sift through the collection of facts and will very likely spot a direction of testing. IE ( I bought the tractor April ???, hours ??? engine clean, hydraulic oil clean, loader with full load fast at 80 F, pump . Now pump noisey at 50F , loader up slow etc etc.

I have a bronson 4520 and my hyd are slow . what's next:

I changed hyd.filter still slow don't know were screen is. Fluid not milkey. When you pull lever back to go up. Pump makes noise builds pressure buckett moves up about 1/2'' and stop pump makes noise builds pressure buckett move up about 1/2'' and so on and so on******

both ; it is a branson 4520 I don't have leak's work fine this summer turned cold got slow

Agreed, Craig. Here's what we have so far. Filter is clean and oil is not milky. It may be dirty and smelly or could be 90w, not sure. Tractor worked fine this summer. Did it sit in storage or under a tree for 2 or 3 months?

Pimp,
Is your flow better at 50 degrees than it is at 20 degrees? Did this problem occur all at once or was it gradual? Is the problem the same at all engine rpm? How much use does this machine get? Do you have any documentation/ shop manuals for the tractor? Give us ALL of the details, observations, sounds , smells, vibrations.:confused2:
