In order to reduce the turning radius on the work, the brake of the brake the tractor is provided w

Tractor Back to simple maintenance TOP of tractor agricultural machinery in the so-called tractor, it is intended laundry hampers as a method most frequently used, fitted with (a type of work machine) Rotary at the rear in order to plow the fields and rice paddies. This is intended to go plow floor nails is allowed to transmit to the tillage shaft of the rotary rotation of the PTO shaft which rotates at a rotational force of the diesel engine, mounted laundry hampers on the tillage shaft is rotated. In agricultural machinery, in addition to the rotary, tractor broad casters to sow Power Disc, a fertilizer for inverting ridge painting machine for making drive-halo, a ridge for as rice fields only, and to puddling, the soil, There is a working machine according to the application, respectively, such as lime, Sowa, like the rotary, and is adapted to be attached to the tractor rear using a three-point link hitch thereof. There is something to be attached to the tractor and front and only lime-Sowa. More some other purpose of mowing, Torencha purpose of grooving, and trailer towing purpose. Type of deal usually rotary working laundry hampers machine failure diagnosis of how to use water-cooled diesel engine laundry hampers and meaning of each name tractor, operating lever structure, such as a button
Name of each tractor, engine structure ... diesel engine, starting system, pre-heating device, charging device radiator (water-cooling unit) Battery Meter panel headlight, turn signal clutch pedal brake pedal steering Transmission ... the main shift lever , sub-transmission lever, the forward-reverse lever, switch lever four-wheel drive two-wheel drive, speed lever (switch), AD lever (switch), PTO shift lever, PTO shaft differential gear ... differential lock pedal front wheels, the front axle working machine mounted equipment (3-point link) ... hydraulic system, working machine falling speed control valve, position lever (dial), depth lever (dial), draft control switch, automatic (manual) horizontal dial, working laundry hampers machine lifting one-touch lever (switch), auto-up switch, back-up switch tire universal joint
Power from the clutch (main clutch) the engine is transmitted to the transmission via a clutch. The clutch is the main clutch, PTO shaft and clutch, friction clutch, hydraulic clutch, and fluid coupling is used from the structure. Often used in the tractor in the friction clutch disc type, is a single-plate type one, the multi-plate of two or more disks, there is a wet-type disc and dry the disk is dry is immersed in oil. Main clutch is used most often dry single plate clutch, but there is also such a wet multi-plate. Further, there is a diaphragm and coil spring in the power transmission is a dry single-plate clutch. Dry single plate clutch diaphragm type is often used, release load (pedal laundry hampers effort) is light, without the release and the master cylinder (release) cylinder as automobile, as shown in the figure on the right, clutch pedal tractor direct clutch pedal through clutch rod, clutch lever, I'm led to the release fork in the housing. ... It depresses the clutch pedal photo of the release set, the release fork to push the diaphragm spring release hub, the release bearing to move the engine side. At this time, when I say a circle, near the center and that it is the pressure plate the outer periphery by the diaphragm spring, pressure plate moves toward the transmission in reverse. A gap is born flywheel, clutch disc, the pressure plate between the transmission of power there is no friction force is gone. It is a so-called state, called off the clutch. Lead movement ... clutch hub and the release fork, adjusting clutch disc of the amount of play cut clutch is worn, play of the clutch laundry hampers pedal is reduced. Therefore, laundry hampers I will in about 20 ~ 30mm the clutch pedal play amount referred to in the right figure. I ... to adjust loosen (split pin and headed pin, such as the R pin fixed), the nut of the adjusting unit remove the one measurement of clutch rod of the clutch disk. When you shorten the clutch laundry hampers rod in the right figure, it becomes easy to slip (run down earlier) and cut at the position clutch is shallow, it is too short when you step on the clutch pedal. The longer the clutch rod in reverse, it possible to cut a deep position, but off of the clutch is bad for too long. Therefore, such as the pressure plate and clutch disc is worn when it comes to overuse, so come now expire at shallow and gradually, laundry hampers to be adjusted by increasing the clutch rod. As much as possible, and to specify the reference value of each manufacturer, it is confirmed that the clutch is turned off completely depress the full clutch pedal. Simple Setup: The parking brake, in the high-speed gear with the engine idling, slowly connecting the clutch, clutch is OK if the engine stall. For long-term storage: If you are long-term storage laundry hampers the tractor, because there is a possibility of sticking to the pressure plate clutch disc is rusty, it should be locked laundry hampers by depressing full of clutch pedal.
In order to reduce the turning radius on the work, the brake of the brake the tractor is provided with a braking device to separate the left and right rear wheels. Therefore, the brake pedal is lined with two left and right, is designed to turn depress the pedal in the turning direction, respectively. However, those who are turning that you want without going through brake just to wear AD-speed devices such as (Kubota designation), the steering wheel, it is not roughened the field is the mainstream now, with more favorite of the former and the latter in any of the user it is possible to use. Further, used as a pedal one by connecting the brake pedal the left and right road travel, it may remain a concatenation of pedals rice fields within Using the AD-speed device. To prevent laundry hampers a sudden sharp turn when the road running, it travels off the AD-speed device. Dry drum-type, such as the figure on the right in only the rear wheel (internal expansion type), there is a wet-type disc, brake used in tractor, is provided to the differential gear shaft together. The tractor now, wet disc brake of mechanical is mainly used. This is because the durable heat dissipation is good because it is immersed in oil at all times, the wear of the disk is small, there is a stable braking force. Such as combine, wet brake hydraulic pressure is or used. I think personally when worn considerably in about 800 hours wet disk. Rarely used currently in the brake of the internal expanding; however brake pedal right figure is the basic form of the brake system. Cry provided laundry hampers the difference between the master cylinder and the vehicle via the brake rod from each of the brake pedal of the right and left, which is operating the brake pedal force and without pressure laundry hampers to the brake lever, respectively. How the angle of the brake cam changes when depressing the brake pedal, laundry hampers the brake lining is opened by being pushed into it, on the inside of the rotating drum is connected to the differential gear shaft, braking by causing friction brake lining has become. laundry hampers Wet disc brakes are likewise connected to the brake lever via a brake rod from the brake pedal. rice planting machine has also become the same mechanism, but the current one pedal, is typically rice planting machine. The internal expansion expressions, such as adjusting the right view of the amount of play, play of the brake pedal is changed in worn brake lining, such as excessive use of time. Wet disc brake current mainstream as well, play the amount of the brake pedal to change brake disc is worn by time and use too much. Therefore, the amount of play of the brake pedal, I adjusted to 20 ~ 30mm about the clutch pedal as well. In addition, laundry hampers to eliminate as much as possible the difference between the amount of the pedal play the left and right (5mm or less). Are provided in the normal brake rod adjuster, what can and what can not be is composed of adjustment nut and fixing nut, turning laundry hampers the adjustment nut If you do not remove the one side of the brake rod, able to turn the adjustment nut as it is I have a. In addition, the brake rod left and right, there are some two by two vertically and horizontally. In general, both ends of the brake rod is fixed each split pin and headed pin, or R pin. As much as possible, I want to specify the reference value of each manufacturer.
Driving force of the differential gear (differential gear) tractor is transmitted differential (differential gear), differential lock, final gear, to the rear wheel axle from the transmission. It is necessary to rotate more than the drive wheels and the inner drive wheel on the outside during turning, the differential gear is to facilitate turning by giving the rotation laundry hampers difference between the left and right wheels. Differential gear used in the tractor has been used 4-pinion pinion type 2 (right panel) in the bevel-gear-type mainly. Differential gear is formed by a bevel gear between the side gears and differential pinion. Differential pinions are mounted to the differential case by a pinion shaft, side gears are engaged here. Side gears are coupled laundry hampers to the axle shaft spline. Resistance applied to the left and right wheels is equal to straight running, the differential gear does not rotate, the side gear and the ring gear rotates in the same direction is integrally. Further, since the difference is born resistance according to the left and right wheels, the differential pinion laundry hampers rotates to correct rotational differential side gears while revolving the cornering. It can pivot smoothly rotational difference is applied to the side gears of the left and right in this effect. In the reduction gear to increase the torque by reducing the rotational speed of the axle shaft (differential gear shaft), final gear is clinging to the wheel axis to the left and right rear main. . It is said that the final reduction gear to a final reduction. In the mud, such as field bad conditions and steps, such as over Def Rock ridge, there are times when the tractor will not move tire idles only one side, it is mechanically locked the differential gear, the rotation of the two wheels at the same time to force It is intended to be. Those that use a pin or dog clutch, operating in differential lock pedal is mainstream differential lock. Thing and that locks the differential automatically, by providing an automatic limited slip differential such as canceling when turning the differential lock is applied at all times when traveling straight slip difference between the left and right wheels other, such as when driving four-wheel drive increases there is was. differential lock pedal becomes impossible to turn it 's remains depressed, only to be used straight.
Transmission of the transmission tractor (transmission), and some combination of gears with different numbers laundry hampers of teeth and size, the apparatus for changing the rotational speed and torque for the job or the traveling speed of power from the engine, the rotation of the gear when reverse I have gone to change laundry hampers the direction. (Eg, 1-4 speed), (eg, 1-4 speed), ultra-low-speed (creep), reverse shift before (for example, 1-3 speed, reverse) transmission of the tractor, from the PTO transmission and sub-transmission main transmission no forward-reverse lever by a machine, configured is a variety, such as that provided to the reverse position to the main shift lever. Accordingly, the transmission can be several tens of steps by a combination thereof. The transmission of the travel, there are a sliding gear type selection (selection-mesh), constant mesh, such as meshing type synchronization, hydraulic HST is capable of continuously variable transmission (such as hydrostatic drive type). (Sliding laundry hampers mesh) sliding selection is a structure that slide the sliding gear of the main shaft on the upper right as diagrams, shifting engagement selectively with the drive gear of counter shaft sliding on selection. It is easy to easy gear tooth tip is worn, causing the gear noise, laundry hampers but because it is a simple structure, it is used to speed and four-wheel drive and auxiliary transmission mainly
