Unfortunately require diagram to go with adjustment procedure.

PTO linkage adjustment:
Loosen the PTO control handle bolts then adjust linkage so that PTO valve movement is 1 3/16in. + or -1/32 in. From disengage to engaged or over center position. Move the control handled to the disengage position then adjust the lever to the center of the notch. Tighten the bolts in control handle. Then with the engine running move control lever to the feathering notch position. When control lever is released, it should move freely to the disengaged position.

Operating pressure:
To check the operating pressure operate tractor until hydraulic fluid has warmed up to approximately 100°F. Refer to figure 116 and remove pressure line (1) from T on left side of tractor. Attach a test gauge capable of registering at least 300 P. S. I. Engage PTO and operate engine at 2200 RPM. If pressure reading is below 220 P. S. I. remove plug from (4) from MCV valve and install shims as required under the valve plug. When the pressure is set at 220-250 P. S. I. Remove the gauge and connect pressure line back to the tee. Then remove the cap from the tee and connect the pressure gauge as shown in figure 161. Operate engine at 2200 RPM with that PTO engaged there should be a gage reading of 220-250 P. S. I. if the sealing rings in the PTO clutch piston and the sealing rings and bushings on the 1000 RPM output shaft (dual speed) or lower PTO drive shaft (single speed) are sealing property. If pressure is not as stated remove and overhaul PTO unit has outlined in paragraph 128.
