90HP 4WD Tractor with Hydraulic Two-Way Disc Plough for Dryland Tillage

The final disc quantity must still be confirmed according to tractor operating weight, rear hydraulic lifting capacity, soil resistance, required working depth and actual field conditions.

A 90HP tractor provides a useful balance between traction, field efficiency and implement compatibility for medium and large farms.

The BSM hydraulic two-way disc plough range covers approximately 65–120HP tractors and includes several disc configurations. For the 90HP power class, a suitable four-disc configuration can be considered when the tractor weight, hydraulic system and soil conditions are appropriate.

Unlike a conventional one-way disc plough, the hydraulic two-way design allows the working direction to be changed through the tractor hydraulic system.

This can help reduce:

• Unnecessary empty return travel
• Repeated implement repositioning
• Time spent realigning at the headland
• Irregular working routes across long fields

This tractor and plough combination can be considered for dryland operations where primary soil turning is required before secondary tillage or seedbed preparation.

Suitable working conditions may include:

• Dry cultivated farmland
• Firm soil
• Clay soil under suitable moisture conditions
• Fields with moderate crop residue
• Medium and large rectangular fields
• Maize and wheat production areas

Very wet soil, very stony fields or steep slopes require additional technical confirmation before operation.

The disc plough uses concave rotating discs to cut, lift and turn the soil.

After completing one pass, the operator raises the implement, turns the tractor and uses the hydraulic system to reverse the plough orientation for the next pass.

This working method is particularly useful on longer fields where repeated return travel would otherwise reduce efficiency.

Primary tillage creates substantial draft resistance, especially in dry or firm soil.

A 4WD tractor can distribute pulling force through both front and rear axles, helping improve traction and reduce excessive wheel slip under suitable conditions.

Actual traction performance still depends on:

• Tractor operating weight
• Tire size and condition
• Ballast configuration
• Soil moisture
• Working depth
• Disc quantity

Within the current BSM hydraulic two-way disc plough range, a four-disc configuration is generally positioned for approximately 80–110HP tractors.

This places a 90HP tractor within the normal matching range.

However, this does not mean every 90HP tractor should automatically use the same four-disc plough.

Hard soil, deeper tillage or a lighter tractor may require a more conservative configuration. Final matching should therefore be confirmed before production.

1. Field inspection: check soil moisture, crop residue, stones and field slope.
2. Connect the disc plough: confirm three-point linkage, hydraulic connections and transport balance.
3. Test pass: begin with a controlled working depth and observe traction and soil turning performance.
4. Adjust working conditions: modify depth, speed or hydraulic settings according to field resistance.
5. Primary tillage: complete repeated passes using the hydraulic reversing system at the headland.
6. Secondary preparation: follow with a disc harrow or rotary tiller when finer soil preparation is required.

Primary ploughing usually leaves larger soil clods and an uneven field surface.

Depending on the crop and local farming method, the next operation may use:

• Disc harrow for clod breaking and residue mixing
• Rotary tiller for finer seedbed preparation
• Planter or seeder after suitable soil preparation

This allows the 90HP tractor to participate in several stages of the same farming season.

Horsepower alone is not enough to confirm this combination. Before selecting the final plough, buyers should provide:

• Exact tractor model
• 90HP 4WD configuration
• Tractor operating weight
• Rear hydraulic lifting capacity
• Available hydraulic outlets
• Three-point linkage specification
• Soil type
• Required working depth
• Farm size
• Field slope
• Main crops
