Just bought a Massey Ferguson 1533. I am fairly familier with tractors but one things I am not quiet sure of is a turn knob just below the seat. It has a rabbit and turttle imagine and can be turned right or left. Is this a varible speed control for the PTO? The PTO is engaged by turning a small yellow knob on the dash. Just not sure what the knob down towards the floor between my legs is for. Any thoughts?
