How can use the fertilizer spreader accurately?

Installation and Commissioning

Hanging and fixing

Connect and fix the suspension device of the tractor to the hanging point of the fertilizer spreader to ensure a firm connection. The position of the fertilizer spreader is determined through the lifting device of the tractor to ensure that the fertilizer spreader is at an appropriate working height. Adjust the upper pull rod of the three-point suspension to make the fertilizer spout in a horizontal position, so as to ensure uniform scattering and a large area of fertilizer distribution.

Install the drive shaft

Lift the fertilizer spreader, install the PTO drive shaft, and ensure that the universal drive shaft is in a horizontal position.

Connect the hydraulic device

If the fertilizer spreader is equipped with a hydraulic control configuration, it needs to be connected to a hydraulic device so that the relevant operations can be completed in the cab through the tractor's hydraulic control device later.

Operation

Fertilizer loading

Lower the fertilizer spreader to the appropriate position through the tractor lifting device. Before loading the fertilizer, it is necessary to confirm whether the screen of the fertilizer box is installed in place. It is strictly forbidden to load fertilizer into the fertilizer box without a screen installed, otherwise it will lead to a decline in the working quality of the fertilizer spreader, and even make it unable to work normally. The fertilizer spreader is only allowed to be loaded when the PTO of the tractor is disconnected.

Startup and speed setting

When starting the fertilizer spreader for the first time, it is necessary to keep the speed increasing steadily. A speed that is too high can easily cause damage to the fertilizer spreader nozzle.

Adjustment of fertilizer content

The fertilizer adjustment device is located above both the left and right fertilizer spreading trays of the fertilizer spreader. It is composed of a scale plate, an adjustment handle, a baffle plate and a tightening hand nut. It is used to adjust the size of the discharge port, thereby changing the amount of fertilizer falling within a unit of time.

Before the operation, the handles of the left and right fertilizer adjustment devices should be indicated at the same fertilizer scale to ensure that the amount of fertilizer spread by the two fertilizer spreading trays is consistent. When adjustment is needed, the discharge port must first be completely closed through the control baffle of the tractor's hydraulic system

The width and amount of fertilizer spread are determined

The width of the fertilizer spread should be adjusted according to the actual situation of the operation site and the size of the fertilizer particles by changing the position of the leaves scattered by the fertilizer spreading tray. The width of the fertilizer spread is jointly determined by the length of the scattering leaves and the hole positions on the fertilizer spreading tray. The amount of fertilizer spread should be determined based on factors such as fertilizer particles, working width, expected operating speed and expected amount of fertilizer spread, and is achieved through the adjustment handle of the fertilizer amount adjustment device.

When opening or closing the fertilizer spreader at the end of the fertilizer-spreading plot, attention should be paid to the distribution and connection areas of the fertilizer-spreading belt. When working, please ensure the ground is level. If it is uneven, detour or pass slowly. When turning or making a U-turn, remember not to stop the drive shaft and drive in a sharp bend.

Maintenance and Care

Adjust the tightness of the chain row

The tightness of the chain row should be adjusted moderately. If it is too loose, it may cause the chain row to derail. If it is too tight without buffering, it may cause the chain row to break.

Regular inspection and maintenance

Regularly inspect and maintain tractors and fertilizer spreaders. Add grease to the fertilizer spreaders at the marked points on a regular basis to ensure the normal operation of the equipment.
