  • does this system provide safety of the tractor flipping ov er backwards? I know person who was killed while pulling with a ford about 5 years ago. I don!t know exactly what happened but he was pulling something out of the ground.

  • Well explained. Now I have an idea how to use the 2nd lever on my TO-35.

  • is there a way of adjusting the top link for plowing? how does one know if the top link is operating properly? do you set the quadrant lever to the very down position for plowing? this may sound elementary,sorry! thanks
    John (UK) wrote on Sunday, September 05, 2004 (PDT):
  • When the implement strikes an object the hydraulic pressure is released and the wheels spin because there is no weight transfer NOT because the tractor is supported by the implement, it would need a double acting ram to do that and there just isn't one.

  • My brother is having a problem with the draft control on his 9n.When he lowers the control it will go down,but won,t stay there unless you hold it there.Any idea,s why?.Thanks

  • Finally a solid description an the three point “Ferguson System” hitch. Thankx Lars
    Chris Jensen wrote on Saturday, November 17, 2007 (PST):
  • It is my understanding that the skirt of the hydraulic piston touches the control forks when the hydraulic system is at maximum lift--This touching of the control forks by the piston results in a movement of the control valve to a neutral positon--John from UK provided this information for me--I haven't seen this information written in research I've been doing on the ferguson hydraulic system

  • Good, simple explanation.

  • now we know why tractors with down force on their three point hitches get stuck so easily!
    ron89 wrote on Sunday, September 14, 2008 (PDT):
  • The Ferg draft system was perfected by specific engineers in the Ford Motor Company in 1939. The later TE 20 system is identical to the 9n system. While the draft concept was Harrys, only the genius minds at Ford could make it a reality. The suction control pump built by Ford was, and is, a nearly perfect mechanism when kept in good condition. Henry Ford and his staff were not fond of making Patents, so their work was not fully recognized. Some of these same engineers are alive and well in 2008.

  • the article is great info, but could someone explain how the control valve works in the block? maybe a cutaway pic?
    charles hall wrote on Monday, August 10, 2009 (PDT):
  • I have a 1954 to-30. Can the lift arms be set at a desired position and have them stay there when using a rear single wheel brush hog? Any reply appreciated. My arms seem to only be all up or all down.

  • Ron. Fergerson already had the pattent,

  • When did the 3 point linkage become popular in England/ireland. was it as late as the 1950s
    Randhawa GS wrote on Sunday, July 18, 2010 (PDT):
  • The effect of reaction of forces on TOP LINK is related to Hyd oil flow at that moment. If u are in habit of using plough at low Engine RPM's, then Hyd Oil flow will also slow down thus effecting efficient corrections of draft forces by the fergusan system. For LOW Engine RPM users, we should go for a higher flow Hyd pumps or u will have to repeatedly compensate with manual corrections through draft lever and your hand may always remain on the lever. Human reaction can not match auto assist reactions.

  • harry ferguson was absolutely light years ahead on draft control! he was a marketer, scientist, engineer, and a labor saver! no matter what brand of tractor your'e proud of, his draft control had a hand in it's success! the three point hitch also contributed to ease of attaching implements, and is an industry standard! thank you, harry ferguson!

  • Back in 1962 was plowing in 2nd gear I hit a rock over 10 ft. were I could see it.I broke the plow shear and bent the draft control rod in the 8Nford.After that I didn't have draft control,plus I broke the key off with my knee and the tractor stalled.

  • No plans really. I used stadrand 10 ft. pvc and made the coop with as few cuts as possible. The biggest expense was netting and zip ties to attach it. I probably used 300-400 zip ties It is pretty simple just draw it out on paper first and then adjust as reality forces you to.
