what can mini excavator do？
Construction
Mini excavators are useful for small to medium-sized construction projects, and can also work alongside larger excavators on larger sites.They can dig holes, foundations, and ponds, create trenches and ditches, and demolish concrete, asphalt, steel, and small structures.Mini excavators can also move materials to and from the job site.Attachments can add capabilities like drilling, ripping, and compacting.
Farming
Mini excavators can simplify farm work like digging holes, moving hay bales, and placing fences.
Landscaping
Mini excavators' light weight and versatility make them useful for landscaping work.
Other uses
Mini excavators can also be used for clearing vegetation, planting trees, setting posts, clearing trails, irrigating, and installing hot tubs.
Do you know the safety knowledge related to mini excavators?
01 Pipeline
Every city has a complex network of pipes underground, digging through or digging up the pipeline is very dangerous, and most of the underground pipeline network does not have drawings to see, do not know the location and depth of the pipeline. In the pipeline landfill will generally be filled with sand first, with sand to protect the pipeline and tamping on both sides. So when the excavator in the city operation suddenly dug pure sand, or suddenly loose soil color is different, that next to it is likely to have a pipeline.
02 Hand-held door frames
There is a very easy to be overlooked dangerous situation, is the excavator in the downhill or off the trailer, due to the body leaning forward, many drivers will be used to the left hand pushed on the front windshield or door frame, the right hand to operate the excavator walking. At this time, if the door is open and not locked, the door will be subjected to gravity and close quickly, and the force is very large. At this time, the hand on the door frame will be pinched. So excavator work, whether the door is open or closed must be locked. Drivers try not to hold the door frame.
03 Working on soft ground
When working on soft ground such as swamps and riverbanks, you should make sure that you can bear the weight of the excavator. If you forget the following procedure, there may be serious consequences.
1. try with the bucket first.
2. Don't stay in the same spot for a long time.
3. take more straight lines and fewer turns.
04 Peripheral vision blind spot
The cab of an excavator is on the left side, and the center is blocked from view by the moving arm, so there is a large blind spot on the right side, especially the right side of the rear is not visible. Many excavator accidents are due to the right side of the tail in the rotation will be hit or killed! So when working on a site that is not very wide, the excavator tries to stay to the left as much as possible to leave more room on the right side.
How to buy a tractor
Selection of the form of the whole machine
Belt-driven small tractors are usually called small four-wheeled tractors, and in recent years there are two kinds of small four-wheeled tractors on the market, namely, 11.0 kW (15 hp) and 13.2 kW (18 hp). 14.7 kW (20 hp) and 8.8 kW (12 hp) small four-wheeled tractors are fewer on the market.
Inspection of safety guards
Check the starter shaft head of the engine; the end of the head must not protrude from the outer plane of the engine case. To prevent the engine running process, people close to the danger; pulley and belt must have a protective cover. In case of danger when people approach during engine operation; there should be a guard on the exhaust pipe. In order to prevent the operator from accidentally touching the burns.
Checking the operating mechanism
The throttle and lever are connected reliably, and there is no jamming when you try to step on them; push and pull the main and auxiliary gearshift lever (gearshift lever) according to the operating procedures to confirm its reliability; the steering wheel should not rotate too much when the front wheels are not moving, and the angle of its free rotation should be less than 30 degrees.
Stop for water and oil leak checks
Observe the bonding surface of each rotating part should be free of drips and flow marks. Hand feel the static bonding surface should be free of wetting.
Tractor types and characteristics
General purpose tractors
General-purpose tractors are mainly suitable for plowing, harrowing, sowing, harvesting and other field operations, can also be used for transportation or stationary operations, but not for plowing and other inter-row operations.
Tractors for medium plowing
It is mainly used for plowing and inter-row work, and can also be used as a general-purpose model.
It can be used for field management of cotton, corn, sorghum, sugarcane and cotton and wheat crops. Replacement of front and rear axles and tires can meet the operational requirements of general-purpose machines.
Horticultural tractors
Horticultural tractors are mainly used for various operations in orchards, tea forests, facility agriculture, mountains, hills and small fields, characterized by small power, small size, low body and light weight.
Crawler tractor
The traveling device of crawler tractor has large grounding area, small specific pressure on the cultivated land, light damage to the soil structure, good anti-sagging performance, and good traction adhesion. But because of its bulky, consumables, high cost. Gradually replaced by improved wheeled tractor.

Inventory of types of farm tractors
wheeled tractor
Wheeled tractor is the most common tractor we see, there are two-wheeled and four-wheeled and other types. They are powerful and widely adaptable, not only for transportation and fixed power purposes, but also for agricultural work such as turning, harrowing and sowing.
Crawler tractor
Crawler tractor, also called chain track tractor or crawler tractor, is very suitable for paddy field cultivation due to the small grounding pressure of crawler tractor and relatively light compaction of soil.
hand tractor
A walk-behind tractor is a small tractor characterized by small size, flexible operation, and reliable use and easy maintenance.
Boat Tractor
Boat tractor is China's original solution to the deep mud and feet of the field operation of the paddy field power machinery, which has the characteristics of amphibious, fuel-efficient, high utilization rate, driving safety and comfort, and at the same time, the slip rate is also larger, in shallow mud and feet of paddy fields for 16% -19%, in deep mud and feet of paddy fields for 23% -27%.
