It also minimizes operator fatigue and improves the operation efficiency resulting from a minimum intervention for depth and draft control under dynamic field conditions. The novel intelligent slip-draft control system also amounted to improve the tractive performance of 9.17% and 6.05% during ploughing and harrowing respectively when analyzed against an existing draft control system. A maximum slip variation of 2% was witnessed between the computed and the indicated values in the developed system. When using an implement that does not engage the soil, like your bush hog, the draft lever is placed (I think) all the way down, and the position control is used to. They are used in conjunction with each other when plowing. The developed system was evaluated with test tractor and analogized with the existing draft control system. Your tractor probably has two levers controlling up and down on the 3ph, a 'draft' lever and a 'position control' lever. Implement draft was recorded using a three-point linkage dynamometer placed between the tractor and implement. Actual and theoretical speeds were digitally acquired through the controller-Hall Effect combination employed on front and rear wheels for the digital accession of the wheel slip. Visibility and seat adjustment No, the draft control lever shouldnt move with the position control lever Posted: Wed 11:30 am Post subject: Re: Draft/Position Control Lever: correction here,9n,2n,and 8n ALL had draft control (1) Support the unit in a vise in a vertical position with the control spring down as shown in fig the zane. Category-II Automatic Depth & Draft Control (ADDC) with auto lift button. The system synchronously measures and controls the wheel slip and implement′s draft closer to the set ranges under varying field conditions. DRAFT, POSITON AND RESPONSE CONTROL LINKS. If your tractor has speed adjustment on the lift it can also affect the draft's operation.A microcontroller-based embedded system for automatic slip-draft control was designed, developed and tested for a 2WD tractor. My best suggestion for you is to put a plow on the tractor and get in a place to just try it at slow speed so you can feel and watch the action of the lift working as you plow. You use the position control to raise and lower the plow or blade or what ever. Then you use the draft control to keep the plow at that setting as the ground raises and lowers. You use the position control to set the depth you want to use the plow at.
But think the Kubota will be most like your Kioti. Years ago had experience with older Ford. I don't think a draft control function can be added to a tractor that does not have it.ĭon't know I can fully answer your questions but on my Kubota it has both draft and position. If I raise up the draft control lever the lower arms raise up just as if the position control lever were raised.
My question is with the position control lever all the way lowered. Position control lever the other the draft control lever.
Draft control on a tractor full#
With a new tractor like yours, you should be able to maintain cutting height with position control. Ok, with a great deal of exasperation, (big mallet, punch and frustration), I undid the nut and removed the draft control spring assembly, the cylinder was chock full of rust dust, Fergie Man is right, there is a lead pellet sqaushed into the thread area against the nut, but still can’t get it out or drill through it, something like a. In a tractor having power adjusting means for effecting adjustment of an associated implement to increase or decrease draft load, a draft load control comprising: a source of pressurized fluid draft sensor means responsive to draft load and providing a fluid pressure output proportional thereto a valve body having first and second chambers provided therein fluid passage means.
A bush hog doesnt give much variation in pulling force. It senses the pulling force of the plow thru the top link, and controls the plow depth according to pulling force. My new Kioti has 2 levers side by side for the 3 point hitch. Draft control is intended primarily for plowing. Old tractors with draft control usually had a lever under the seat to activate the draft control then you used the 3 point hitch lever to set the depth. Using the draft control, the lower arms are raised by the hydraulics to keep the plowing depth constant. A feature called Traction Control functioned much like Ferguson's draft control by adjusting the implement's depth to keep the draft load constant. This will eventually spin the wheels or stall the tractor. If you have a mouldboard plow on the tractor it will keep plowing deeperīecause of it's design. Draft control on a tractor usually uses the lower hole for mounting your top link of the 3 point hitch.
