What should I do if the Dongfeng 404 tractor lifter descends too slowly?

If the tractor lifter descends too slowly, then you need to drive to the repair shop for overhaul before you can find out**.

Hello, the slow acceleration of the Dongfeng 404 tractor is that the valve needs to be adjusted, and the fuel filter element needs to be replaced.

If the speed is too slow, you can adjust the speed, and then press the corresponding button or remote control, and it will definitely adjust its speed.

Insufficient hydraulic lifting force should check whether the pressure of the system relief valve is appropriate; Then check whether the oil delivery performance of the oil pump has decreased, otherwise the oil pump will have to be replaced.

As we all know, now small chassis tractors are rampant in the market, low and high horsepower, while large chassis tractors are unsalable due to high and low horsepower. 554 tractor has a large chassis, medium chassis, small chassis, to a brand of tractor as an example, the minimum mass of the large chassis 554 tractor is about 2420kg, the minimum mass of the chassis 554 tractor is about 1860kg, and the minimum mass of the small chassis 554 tractor is only about 1335kg. Similarly, 404 also has a large chassis, medium chassis, small chassis, the minimum mass of the large chassis 404 tractor is about 2090kg, the minimum mass of the medium chassis 404 tractor is about 1740kg, and the minimum mass of the small chassis 404 tractor is about 1330kg.

I personally don't have a good way to do this, if I change it, it's a bit uneconomical to be honest, or I personally don't have a good way, so I can only modify it and try it.

The hydraulic suspension system automatically adjusts the expansion and contraction of the suspension cylinders according to the road conditions, ensuring that each tire is subjected to the same load. The hydraulic suspension system is also a lifting system for the body, which can evenly raise the height of the body when a.

Insufficient hydraulic lifting force.

It should be checked that the pressure of the system relief valve is properly adjusted;

Then check whether the oil delivery performance of the oil pump has decreased, otherwise the oil pump will have to be replaced.

If the tractor suspension of this brand goes down, then you can install some more parts on the car, or install some springs to absorb the shock.

There is friction between the brake pads and the wheel hub to generate heat, the so-called abnormal noise; The abnormal sound during driving is the grinding sound, and the sound after parking is the cold shrinkage sound of the brake helmet.

It can increase the power by about 20 horsepower. I Lovol 490 machine after supercharged 60 horsepower.

It can increase the power by about 20 horsepower. My Lovol 490 machine can increase the 60 horsepower by about 20 horsepower after supercharging. My Lovol 490 machine can increase the 60 horsepower by about 20 horsepower after supercharging. I Lovol 490 machine after supercharged 60 horsepower.

Tractor: A self-propelled power machine used to tow and drive work machinery to complete various mobile operations. It can also be used as a fixed working power. It is composed of engine, transmission, walking, steering, hydraulic suspension, power take-off, electrical instrumentation, driving control and traction and other systems or devices.

The engine power is transmitted by the transmission system to the drive wheels to make the tractor drive, and in real life, it is common to use rubber belts as the medium of power transmission. According to the function and use, it is divided into agricultural, industrial and special-purpose tractors; According to the type of structure, it is divided into wheeled, crawler, boat-shaped tractor and self-propelled chassis.

The so-called shift shift refers to the fact that when the car is driving, the gear lever automatically returns to the neutral position, so that the sliding gear is out of the normal meshing position. Transmission shift is one of the common faults, which is caused by loose wear and damage of the transmission-related parts, or improper adjustment of the matching clearance.

The reasons are as follows:

1.The gear lever alignment pins are worn loose, broken or missing, causing them to lose control and swing arbitrarily.

2.Abrasion failure of the interlock device of the variable speed fork shaft; The gear lever ball joint is too worn and loose.

3.The gear, ring gear or sleeve of the gear is worn into a tapered shape in the direction of the tooth length and is out of gear due to the axial force generated during operation.

4.The shift fork shaft chute, lock pin and other parts are too abrasive, the fork is bent and deformed, or the working face and the gear ring groove are abrasive.

5.The rear end of the second shaft is loosened, causing the second shaft to move axially.

6.The locking pin of the synchronizer is loose or falling apart, and the cone surface work fails.

There are several possibilities. 1. The pump is broken, 2 the valve is broken, 3 the cylinder is broken, 4 is out of oil, 5 the connection part is broken. It is better to find a professional to repair it.

Tractor rotary tiller plough depth adjustment method:

Use the floating rotary tiller to put down the tractor when you feel that the tractor is struggling, Bao Te is neutral, shallow forward to shoot the control lever, deep to the back of the shot, do not stop too long, otherwise put too much or the knife shaft off the ground.

Rotary tiller, full name rotary tiller, is a driven soil tillage machine with rotary cutter teeth as the working part. Modern rotary tillers, according to the knife shaft transmission mode, are divided into intermediate drive rotary tiller and side drive rotary tiller; According to the power transmission mode, it is divided into gear-driven rotary tiller and belt-driven rotary tiller; According to the configuration of the rotary tillage shaft, it is divided into two categories: horizontal axis type and vertical shaft type.

Transverse axis rotary tiller, the knife shaft is horizontally transverse, can be used tractor traction and as a power output, has a strong ability to break the soil, a operation can make the soil finely broken, the soil and fertilizer are mixed evenly, the ground is flat, to meet the requirements of dry land sowing or paddy field planting. However, it has a poor ability to cover stubble and weeds, and the ploughing depth is shallow (1216 cm for dry tillage; hydroponic 1418 cm), the energy consumption is also relatively large. It is mainly used in rice and vegetable fields, and is also used in orchard cultivation.

The heavy-duty transverse axis rotary tiller can reach a depth of 2025 cm and is mostly used for cultivating shrubland, marshland and grassy wasteland.

Vertical shaft rotary tiller, the main working part is the rotary tiller equipped with a spiral cutter. During operation, the rotary tiller rotates around the vertical axis, and the cutter chops the soil. It is suitable for paddy field hydroponics, which has a strong role in soil fragmentation and pulp, but the coverage is relatively poor.

At present, there are many applications of horizontal axis rotary tiller in China. In order to enhance the tillage effect of the rotary tiller, some countries and regions also install various additional devices on the rotary tiller, such as hanging a nail tooth rake behind the rotary tiller to enhance the effect of soil crushing, and installing a loose soil shovel to deepen the deep ploughing layer and so on.
