Lawn Mower

9G Sickle Lawn Mower

Working Principle of a Sickle Lawn Mower: A sickle bar mower primarily consists of a cutter, a blade drive mechanism, a cutter lift mechanism, safety devices, and a grass retaining device.

The cutter lawn mower uses power to drive the reciprocating motion of the blades, which intersect and cut the grass or crop.

The power source can be a gasoline engine, a diesel engine, or an electric motor.

This power is transmitted to the blades through a transmission system, enabling them to move back and forth quickly and regularly, achieving the cutting operation.

Structural Features of a Sickle Bar Lawn Mower

Blades: Typically comprised of multiple slender blades arranged in a straight line and fixed to a cutter bar. The shape and size of the blades vary depending on the mower model and intended use. They generally have sharp edges, effectively cutting grass stems and crop stalks.

Rotary drum mower DM series

Working Principle of a Rotary Drum lawn mower
The cutter of a rotary drum mower consists of multiple blades fixed to a rotating drum, typically located at the bottom of the machine.

The engine or power source drives the drum at high speed through a transmission.

As the drum rotates, the blades rotate with it, working with a fixed bedknife to create a shearing action, severing grass stems, much like scissors, except that the "scissors" here consist of rotating blades and a bedknife.

Disc mower (DRM)series

Disc mowers work by rotating a series of discs, each equipped with a sharp blade.

A power source (such as a tractor's PTO) Lawn Mower drives the discs at high speed through a transmission mechanism.

As the blades rotate, they contact the grass, using centrifugal force and the blades' sharp edges to cut the grass. The cut grass is then left to dry.

Sickle bar mower with raker （9GBL)

Structural Features of a Sickle Mower with a Rake

The mowing section is similar to a traditional sickle mower, primarily consisting of a cutter and a blade drive mechanism. The blades on the cutter are arranged in a straight line and driven by a powertrain to perform a reciprocating motion, severing grass stems.

The rake is typically mounted on the rear or side of the mower and comes in various configurations, such as a raking rake or a ditch-clearing rake.

The rake's structure generally consists of tines and a frame. The shape and spacing of the tines are designed to suit different needs.

Some lawn mower tines are densely packed for collecting fine grass leaves, while others are sparsely packed for clearing larger debris or gathering bundles of grass.

Connection and Transmission: The rake is secured and connected to the mower body via a connecting mechanism, ensuring stable movement.

A corresponding transmission mechanism also enables the rake to be driven by the mower to perform actions such as raking or clearing. The transmission method can be mechanical or hydraulic.

Lawn Mowe Spring rake 

Working Principle of a Spring Harrow
Soil Breakup and Leveling: When a tractor pulls a spring harrow forward, the spring tines penetrate the soil.

As the tractor moves, the tines cut through the soil, breaking up and loosening clumps.

Because the tines are elastic, they automatically adjust their insertion depth and angle based on the soil's hardness and resistance, ensuring even soil breakage without excessive or uneven breakage.

The tines also level the soil surface, creating ideal conditions for subsequent seeding, fertilization, and other operations.
 

Weed Removal and Stubble Management: During lawn mowe the harrowing process, a spring harrow removes weeds from the field and evenly spreads weeds and crop residue on the soil surface, exposing them to sunlight for accelerated decomposition and increased soil fertility.

Furthermore, Lawn mowe the turning action of the tines destroys weed roots and seeds, reducing weed growth and the competitive pressure they pose on crops.

Soil aeration and moisture conservation: The rake's tines stir and break up the soil, increasing soil aeration and allowing air to enter the soil, promoting microbial activity and root respiration.

Harrowing also cuts capillaries in the soil, reducing water evaporation and conserving moisture, which is beneficial to crop growth and development.

Lawn Mower Pasture harrow

Chain Rake Structure:
The tine chain is the core component of a chain rake, typically made of high-strength metal materials such as steel or alloy. The lawn mower pasture harrow chain is equipped with evenly spaced tines.

The shape and size of the tines are designed to suit specific needs, typically featuring sharp triangles or curved hooks to better capture and gather grass.

The transmission system drives the tine chain. Common transmission methods include gears, chains, and hydraulics. Connected to a tractor or other power source, it transmits power to the tine chain, enabling it to move at a specific speed and direction.

The frame structure supports and secures the tine chain and transmission. Lawn mowe typically utilizes a sturdy metal frame capable of withstanding the various forces acting during raking, ensuring stability and reliability.

The suspension system connects the chain rake to the tractor or other pulling equipment. A three-point hitch is typically used, allowing for easy adjustment of the raking depth and angle to suit varying terrain and grass conditions.

Heavy lawn mower duty rear mounted slasher

A heavy-duty rear-mounted mower is pulled forward by a tractor.

Power is provided by the tractor's power output shaft or the mower's own engine, which drives the cutting disc through a transmission system to rotate at high speed.

The rotating blades sever grass stems, weeds, and shrubs they come into contact with, completing the mowing operation.

During the mowing process, the suspension system adjusts the mower's height and angle in real time based on the terrain and the required cutting height, ensuring uniform and consistent mowing results.
