FS770-30 3.0m Heavy-Duty Deep Tillage Cultivator

Powered by a 566 kW Weichai diesel engine, the FS770-30 combines a 3.0 m working width, up to 700 mm tilling depth and six rotary auger assemblies. With an operating weight of 18,500 kg and a hydrostatic crawler drive system, it is designed for demanding agricultural and land reclamation projects where conventional tractor-mounted cultivators cannot provide sufficient depth or power.

Compared with the smaller FS550-21, the FS770-30 offers greater working width, deeper tillage and higher power, making it the heavy-duty model in the HBXG deep tillage cultivator range.

700mm Deep Tillage for Compacted Soil Layers

The FS770-30 provides a maximum tilling depth of 700 mm, significantly deeper than conventional surface cultivation equipment.

This allows the machine to work through deeper compacted soil layers and hard soil structures that can develop after long-term farming, repeated heavy machinery traffic or insufficient deep cultivation.

Typical deep tillage tasks include:

● Breaking compacted soil layers
● Deep soil loosening
● Pulverizing hardened ground
● Large-scale farmland rehabilitation
● Land reclamation
● Deep agricultural soil preparation
● Preparing disturbed or heavily compacted land

Actual operating depth should be adjusted according to soil hardness, moisture content and required ground conditions.

3.0m Working Width for Large-Scale Operations

The FS770-30 provides a 3000 mm working width, allowing a larger area to be treated during each pass.

This makes it particularly suitable for:

● Large farms
● Land reclamation projects
● Large plantations
● Agricultural development projects
● Large-scale soil improvement programs

Compared with the 2.1 m FS550-21, the FS770-30 provides approximately 43% more working width per pass.

For projects covering large areas, the wider working system can reduce the number of passes required across the site.

Six Rotary Augers for Deep Soil Pulverizing

Instead of conventional fixed cultivator tines, the FS770-30 uses six rotary auger assemblies.

The rotary tillage system reaches a maximum rotational speed of 545 rpm.

As the machine moves forward, the rotary working units penetrate and work through the soil to perform several functions:

● Loosen deep soil
● Break compacted layers
● Pulverize large soil structures
● Mix loosened soil
● Prepare the ground for subsequent agricultural operations

This working principle differentiates the FS770-30 from conventional deep tine cultivators and tractor-mounted chisel cultivators.

It is more accurately classified as a self-propelled rotary deep tillage cultivator designed for high-power soil loosening and pulverizing.

566kW Power for Heavy-Duty Deep Tillage

Deep tillage at 700 mm creates considerably higher resistance than ordinary shallow cultivation.

The FS770-30 is therefore equipped with a 566 kW Weichai WPG770E302 diesel engine with a displacement of 16.72 L.

The high engine output provides power for both machine travel and the hydraulic rotary tillage system.

This allows the machine to work in demanding soil conditions where lower-powered agricultural machinery may struggle to maintain deep working depth.

High-Flow Hydraulic Rotary Tillage System

The deep tillage system uses a dedicated electro-hydraulic circuit.

Key hydraulic specifications include:

The high-flow hydraulic system supplies the six rotary tillage assemblies and supports high-load soil pulverizing operations.

The machine also uses separate hydraulic circuits for travel and implement control, allowing the major functions to operate independently.

Hydrostatic Crawler Drive

The FS770-30 uses a double-circuit electronically controlled hydrostatic driving system.

Travel speed can be continuously adjusted between 0 and 13 km/h.

This allows the operator to select a suitable travel speed according to:

● Soil hardness
● Tilling depth
● Terrain
● Required soil pulverization
● Machine load

For difficult deep tillage conditions, a slower working speed can be used to allow the rotary system more time to work through the soil.

Elevated Sprocket Rubber Track Undercarriage

One of the most distinctive characteristics of the FS770-30 is its crawler undercarriage.

The machine uses:

● Triangle-shaped track configuration
● Elevated sprocket design
● Elastic suspension
● 450 mm rubber tracks
● 2350 mm track gauge
● 380 mm ground clearance

The tracked structure provides a large contact area with the ground and helps deliver engine power to the soil during high-load cultivation.

The elevated sprocket arrangement also separates key drivetrain components from direct ground contact.

For a heavy 18.5-ton deep tillage machine, this crawler configuration contributes to traction and stability when operating on uneven agricultural land.

Heavy-Duty Machine for Large Land Improvement Projects

The FS770-30 is not designed as a conventional seedbed cultivator or row crop cultivator.

It is more suitable for heavy soil treatment before intensive agricultural development.

Typical applications include:

Farmland Deep Tillage

Deep loosening of agricultural land where conventional equipment mainly works the upper soil layer.

Compacted Soil Rehabilitation

Breaking deeply compacted ground caused by repeated machinery traffic or long-term agricultural use.

Land Reclamation

Preparing uncultivated, disturbed or compacted land for agricultural development.

Plantation and Orchard Development

Deep soil preparation before establishing new plantations, orchards or other large agricultural projects.

Large-Scale Soil Improvement

Deep loosening and pulverizing where soil structure needs to be improved across extensive working areas.

FS770-30 vs FS550-21

HBXG currently provides two self-propelled deep tillage cultivator models.

Choose the FS550-21 if:

● A 2.1 m working width is sufficient
● Maximum 500 mm deep tillage meets the project requirement
● A smaller and lighter machine is preferred
● Working areas are relatively limited

Choose the FS770-30 if:

● Up to 700 mm deep tillage is required
● A 3.0 m working width is preferred
● Large working areas need to be covered
● Soil conditions require greater power
● A heavy-duty deep tillage solution is required

When Should You Choose the FS770-30?

The FS770-30 is worth considering when a project requires several of the following conditions:

● Tilling depth approaching 700 mm
● Large 3.0 m working width
● Highly compacted soil
● Large agricultural working area
● Self-propelled operation
● High-power rotary soil pulverizing
● Crawler mobility
● Land reclamation or intensive soil improvement

Before selecting the machine, HBXG recommends evaluating actual ground conditions rather than choosing by engine power alone.

Important information includes:

● Soil type
● Soil hardness
● Soil moisture
● Required tilling depth
● Working area
● Terrain slope
● Expected working hours
● Local climate
● Transportation requirements

Why Choose HBXG for Heavy-Duty Deep Tillage Equipment?
