![]() If you hit hard soil you do NOT have to readjust the implement height to keep from stalling or spinning the wheels. This is the genious of Fregusen's design. When you drive forward the hydraulic system will continually adjust itself to maintain the setting you have set. This is the lightest, or shallowest, draft setting you can acheive. If you carefully move the control lever, from full up, down very slowly, you will reach a point where the implement will slowly drop. In the down postion, the touch control lever sets the "draft" you want for the implement you are using. Thus with draft control the implement is either full up - transport position - or full down - in working position. Where as draft control sets the amount of drag - or depth of a plow. Position control allows you to set, and keep set, the height of an implement anywhere within the lift range from full up to full down. In uneven ground, varying soil conditions, the farmer had to readjust the plow as he went along, NOT an easy task. Until Ferguson's hydraulic control design came along, maintaining a constant depth, consistant with the pulling ability of the tractor was a constant fight for the farmer. ![]() Both seem appropiate for the task of plowing where you have both a pulling load and a depth you are trying to maintain. Another meaning is the amount of load when pulling. One comes from the nautical usage for the depth of the water needed to float a boat. Let's start with the term draft which has several old meanings. Re: 8N Ford Position and Draft Control in reply to Clarence Johnston, 10-02-2000 16:20:49 ![]()
