Mf 135 draft control7/21/2023 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.
