Hello Hotpot,
Your tractor is very similar to one of mine. The knob on the right hand side is for the "Isolating Valve". The manual says: "This valve is used to isolate the three point linkage. Closing the valve, hydraulically locks the linkage thus providing a safety device against inadvertent movement of the position control lever. NOTE: The valve must always be fully open or fully closed."
On the left hand side is the "Response Control". The manual says: "This regulates the delivery from the hydraulic pump to the hydraulic system. Push in the knob and turn it anti-clockwise for slow delivery rate."
If your three point linkage works at an acceptable speed why don't you do what I have been doing for 45 years or so: don't touch either knob?
