This 135 has only a linkage pump and one auxiliary fast coupler intended for trailer tipping etc. On top of the lift cover a smaller cover, that can be replaced with a selector valve, that could steer linkage pump's output to external use. On later models this has often a broken linkage from cabin, so better check here underneath. On central housing's left round cover there's the dipstick for common hydraulic and transmission oil and also the response control lever, that affects to linkage's sinking speed. This 1965 Massey Ferguson 135 has the similar functions Position control, transport, constant pumping and pressure control sectors on inner quadrant and the draft control on outer quadrant. Originally this tractor should have Kontak spool valves, but this 590 I installed an universal type Valvoil valve block. On front the levers for auxiliary hydraulic outputs. On braking the return line should be below the oil surface. And it could rotate a hydraulic motor with adjustable moment or the motor could brake on adjustable moment. The pressure control could be used to lighten linkage attached or even towed machinery. Could be used on many other purposes, but is a bit forgotten mainly because of 4WD and more modern tyres. The pressure control is originally ment to transfer weight to 2WD tractor back wheels with the aid of a special coupler or chain between the three point lift and the trailer drawbar. This is better to find out with some more pleasant way than being between the tractor and the implement. With high enough pressure the lift rises on top position. The lever front down the pump gives about 7 bar pressure to lift cylinder and when moved upwards the pressure increases linearly to about 210 bar, independently of the lift arms position or top link push-pull. Pressure control is actually constant pumping on adjustable pressure. The position lever is now moved pass the constant pumping and to the pressure control sector. The quadrants are with adjustable stops and the levers with spring loaded tension screws. When the draft control isn't needed, I use special locking plates on top link bracket to reduce innecessary stress on sensor. When the lever is moved rear, the plough rises as high as the position lever is set and the top link push or pull sensoring doesn't affect. Moving this forward (left) lets the plough to get into the soil and the 3-p lift reacts to the push and pull on the top link and keeps the plough in the right depth though the tractor tyres would sink in the soft ground. The draft control lever is used for example in ploughing. So nearer to the mudguard is the draft alias depth control quadrant the lever is usually rear as in the pic.

An exeption to this is if the outer lever alias the draft control lever is used instead It's operating direction is opposite to the position control lever. If the pump output isn't routed to some other use with the 3-way selector valve, don't leave the position lever on constant pumping.

On constant pumping the system pumps at full pressure against the relief valve and the lift cylinder. Near the quadrant bend is the implement transport position and over the bend the constant pumping (blue) sector. When the lever is moved towards center of the quadrant, the lift arms rise. When the lever is rear (right), the lift is down. The lift arms move on the same direction as the position control lever. Nearest the seat the position control quadrant.
