![]() Even checked to see if the float lever made a difference in operation in any position. It seems to lift me full range, no problem. I even checked the lift height, by having it lift my body weight by me standing on a lift arm. When I detach the bush hog, the lift arms lift, what appears to be 18" to 24" high. When having a 5' foot bush hog connected to the 3 pt arms, the lift height is maybe 3" to 4" max. The issue that I am having is with the lifting of an implement on the 3pt. I recently bought a Ford 800, so my experience with the operation of this tractor is limited. Then set the quadrant lever stop to the bottom of the touch control lever so it will not drop any further down.Looking for some advise on an issue with Ford 800. Continue to lower the touch control on the quadrant in fractions of an inch until the depth you desire is reached. This will allow the plow to go a little deeper. This will increase the distance that the draft plunger spring on the back of the tractor at the top link connection has to be compressed. To make the plow go deeper just move the touch control lever a fraction of an inch lower on the quadrant. It should go into the ground only slightly and no further. Do not lower the touch control any further and try the plow at this position of the touch control handle. The 9N Ford tractor has a very effecient "Draft control" The way it works is you move the touch control handle until the plow begins to drop. The deeper or more draft you want to put on the plow/tractor the lower you are required to lower the place on the quadrant where the touch control handle/lever is placed. As the plow is lifted the stress on the top link becomes less on the big draft spring and this in turn lets the pump tend to drop the plow to the preset position you have selected on the quadrant touch control handle. The lower you have the touch control handle set on the quadrant the more the big draft spring has to compress in order to push against the internal linkage that will try to make the control valve in the pump start to lift the plow. When the plow point engages the ground and the plow starts to try to rotate on the drawbar hook up pins at the ends of the lift arms the top link then begins to push in towards the back of the tractor and compresses the big spring on the lift housing. When the plow point tries to pull back on the tractor this is what the word "draft" means. When you let the lift down so that the plow touches the ground and begins to go into the ground the plow tends to rotate on the two points of the draw bar of the plow/implement. Thus it is called automatic draft control.ĭraft control is the automatic depth control of a ground engaging implement such as a turning plow or a cultivator. When a hard place in the ground is contacted the spring is compressed till it comes in contact with the linkage to the control rod and pushes the control valve in till the plow is raised to the point where the pressure on the big spring on the top link is slightly released thus letting the control rod move back toward the down position and stabilizing the draft of the plow. This is accomplished by being able to set the control valve link inside the lift closer or farther away from the plunger rod that is attached to the top link which is in turn attached to the top of the turning plow or cultivator linkage. ![]() He incorporated an automatic device that allowed you to set the amount of draft or pull on the plow and it would automatically raise the plow if a harder piece of soil was encountered with the plow or let it down a little if an easier place to pull the plow was encountered. He finally invented a hydraulic lift that had 3 points for attaching his specially built 3 point implements such as turning plows and cultivators. Harry Ferguson had been making and selling tractors for years in the early 30s. ![]() Yout draft control works about the same as the 9N he refers to. This is a very good explanation of the draft control function by Zane one of the most knowledgeable mechanics on these boards. ![]()
