Having an issue with the hydraulic lift on a Ford 1900. When the tractor is first started, the lift works perfect. After you mow with the bush hog for 20 to 30 minutes and the fluid gets hot, you start hearing a sound like the pump is starving and the lift drops. When you try and raise the lift, it will raise and fall back down on its own until it eventually drops and will not raise at all. You can let the tractor sit for a couple of hours and the lift will work like new again until it gets hot and you go through the same thing all over again. The hydraulic fluid was drained and refilled with new fluid and it does the same thing. Any ideas on what to look for would be appreciated.

Howdy telrod,
Be prepared - you are going to have to drain the fluid because the suction screen is at the bottom of the reservoir. If the fluid looks bad, you might as well put new fluid in the reservoir. Use Universal Tractor Fluid (UTF) equivalent to Ford spec 134D (read the label on the bucket). You can find UTF at Tractor Supply Stores, auto parts stores, Walmart, etc. Comes in 5 gallon buckets. About $40/bucket. I don't know how much your tractor takes.....you will need at least two 5 gallon buckets.
