Tractors, tools and machinery through the hydraulic system, to connect to the tractor, transport, field conditions and settings is now easier to run. For example, if necessary, by means of hydraulic systems, tools and machines, folding, opening, rotation, right-left and back of the trailer to remove the evacuation has been made. Tractor is located behind the main hydraulic system and, in some tractor hydraulic system has a separate front.

        HYDRAULIC SYSTEM PARTS
        1. OIL TANK AND PUMP:
        The main article in the hydraulic system to move hydraulic oil. Hydraulic systems used for oil, gear box, or differential in the lubricating oil is provided. Get out of here and as the pressurized oil to places that transmits a pump is available.
        2. HYDRAULIC CONTROL CENTER AND CRAFTS:
        Pump means, given a certain oil pressure movement, movement control center revenue. Pressurized oil, set to work to be done here through the arm is sent to the hydraulic cylinder.
        The effect of hydraulic control centers that are 4 arms:
        Download-lift arm ·,
        · Pre-selection lever,
        · Slowing arm,
        · Transport (lock) lever
        Lifting Arm-· Download: This is behind or in front of the tractor through the arm, hydraulic arm that is connected to the machine tool and to download and removal is provided.
        Pre-selection lever "in the case was''TOWED CONTROL, download the most down-lifting is received, tools and machines" SWIMMERS becomes''POSITION. Position themselves in case of machine tools swimmer and sink into the soil and work with weights. Rakes, lawn mower, with instruments such as the seed drill in this case is sought.
       · Pre Selection Handle: Hydraulic control center, the second arm is affected. There are two positions of the front arm choice.
        a) "trailer control''status,
    b) "Position control''status
    a) Draft check status: Generally, the position is above the pre-selection lever. Each tractor in the maintenance and manuals

These issues are specified. But you do not care and manual and tractor on the process by doing the following text was deleted, which in the position of the arm that is.
        - First tractor runs and gear will be wasted.
        - Hydraulic system's connection to arms, is connected to a device that can easily installed.
        - Tractors given to the transfer of gas is raised slightly.
        - Hydraulic lifting arm upward-download removed at a certain level is kept. In this case, tools and machines lifted completely up front if the selection column "TOWED CONTROL is''condition. If you do not leave tools and machines full, up to a certain level if the "situation is''POSITION CONTROL. The status of work to be done according to pre-select the arm is changed. Plow, Harrow, Cultivator, and pre-select the arm while trying dipkazanla "CONTROL''state must be TOWED.
        b) Position control status, hydraulic tools and machinery that are connected to link arms in a certain height, keeping the soil causes it to run on. Disinfection machines, baling machine, centrifuge machine, such as fertilizer distributing machines when working with pre-position control lever in the event must be selected.
        Position control is performed in case the version with the plow to plow the soil buoyant.

        Reaction (mixture) control status; this case is available in modern tractors. Fields of gold and land in the rugged conditions in places that are hard or soft, smooth version of deep and can not be equal. Types of tillage tools and machine hangs (such as plow) from the blows (impulse) to the upper or lower link arms, there is transmitted to the hydraulic system and plow automatically rises up, when I moved the restored barrier depth is reached. Status and position control of machine tools and captured, under the influence of the two runs. Therefore, the situation is a mixture of these two.
        · Slowing Handle: Download-lifting tools and machines have been replaced by the slow downloading status is taken into arms. Thus, tools and machinery in the place of the damaged hard is prevented.
        · Transport (Lock) Handle: Tractors, tools and machines that are connected to, departure and return to work in the tools and machines are hydraulic lift status is held. Equipment and machinery for the hydraulic cylinder is above a constant load and pressure will do. Therefore, the hydraulic cylinder to the damage. To remove the pressure on the hydraulic cylinder "Carriage Lock''is available. Using departure and return to work in these key lock lever is locked. Field studies certainly should open the lock. This lock can be mechanical or hydraulic.
         HYDRAULIC LIFTING SHAFT AND HANDLE
        Hydraulic control center to be affected by oil revenue and hydraulic pressure to the hydraulic cylinder piston movement to provide. Piston pushes the lever arm lifting, lifting the lifting arm shaft rotates. With the removal of the long arm is lifted up. The long arm of the tool or machine is connected to raise their left-right suspension arm. Lifting shaft, hydraulic piston and cylinder is in a closed section, are not visible from the outside. Hydraulic suspension arms can be seen from the outside of the tractor.
  
         HYDRAULIC SUSPENSION ARMS

        Agricultural tools and machines connected to the tractor three-point strap and they are carried in this way.

Three-point suspension system components are as follows.
        1) top link arm
        2) Left arm suspension
        3) Tension chains
        4) Lower link arms
        5) Right-arm suspension
A and B suspension link arm holes.
        Upper Arm Link: whether the extension be reduced by shortening that connect the front of the instrument or machine-made rear ensures parallelism setting. Machine tools and the requirements of the top link arm, both attached to the tractor side with holes in the round trunnion shafts attached to the trunnion can be no space between.
        Strap Handles: Lifting arms combine with lower link arms are pieces. Some older models of tractors is set just the right suspension arm. In the new model tractors, both also located on the suspension arm with arms extended check the settings may be shortened. This arm attached to the tractor with the machine tool and left-right parallelism adjustment is made.

        Alt Link Handles: Three point suspension system, the two arms of the machine is attached to shaft connection.
        Tensioner Chains: Tools and machinery moved, the rear tire shake and prevents damage to the friction. In the field of working conditions are tightening the chain tension. But until the pull-off wheels are made of four fingers.
