WD 3-point hydraulics

Since you don't want traction boost, you don't need that drag link to the pump. The most commonly used set up for me is the hold position setting and from the discription of the implements you intend to use, this is the pump setting you'll want too. You should have a decal on the battery box showing the various setups for the pump. In any case here is what you need to do.

That draft regulating lockout lever that you pushed forward should have a knurled adjustment bolt in it. (This is adjustment "A" on the decal.) Push the lever forward again and turn this bolt all the way into the body detent (there should be a detent in the pump body that the point of the bolt will mate to) locking the plate into position. Since you didn't mention anything about this adjustment bolt, it may be missing. Look for the threaded hole on the lever and find the detent on the pump body (may have to dig it out from under some caked dirt). Next, take any bolt that will fit and grind the end to a slight point to fit the body detent. This is your main problem. Get the pump set up so it ignores the drawbar and it will behave itself.

The rest of the hold postion settings are as follows. A second knurled bolt is on top of the pump on the side linkages. This is the hold position adjustment. Turn it so that it locks the two plates together, allowing them to move as one. The third knurled bolt is also on top but on the front of the pump. This controls the delay lift. Turn it all the way out until it hits its stop. The last knurled bolt is on the front of the pump about half way down. It controls the rate of lift. Turning it all the way out gives you fast lift. All the way in is slow lift.

Good luck.
