The BSM 1BJ Series Hydraulic Folding Disc Harrow is designed for efficient secondary tillage and large-area soil preparation with approximately 45-160HP agricultural tractors. It is mainly used for breaking soil clods after primary ploughing, loosening cultivated soil, mixing crop residue and fertilizer, removing light surface weeds and preparing seedbeds before planting.
Compared with a compact mounted disc harrow, the hydraulic folding structure provides a much wider working width while still allowing the machine to reduce transport width when moving between fields. This makes it particularly suitable for medium and large farms, commercial operators and buyers who require higher daily field capacity.
Main Applications
- Breaking soil clods after primary ploughing
- Secondary tillage and seedbed preparation
- Loosening cultivated soil
- Mixing crop residue and fertilizer into the soil
- Removing light weeds and surface stubble
- Preparing maize, wheat, soybean and cotton fields
- Large-area farmland preparation
- Medium and large commercial farm operations

Linkage: Hydraulic trailed connection with a compatible agricultural tractor.
Tractor horsepower is only one reference for model selection. Tractor weight, hydraulic configuration, soil hardness, field slope, required working depth and transport conditions should also be confirmed before ordering.
How to Choose the Correct 1BJ Model
The correct hydraulic folding disc harrow should be selected according to tractor horsepower, tractor weight, hydraulic system, soil condition, field size and required daily working capacity.
- 45-65HP tractors: 1BJ-2.0 with approximately 2000mm working width.
- 75-100HP tractors: 1BJ-4.4 with approximately 4400mm working width.
- 100-120HP tractors: 1BJ-4.8 with approximately 4800mm working width.
- 140-150HP tractors: 1BJ-5.3 with approximately 5300mm working width.
- 140-160HP tractors: 1BJ-6.0 with approximately 6000mm working width.
For harder soil, wet fields, sloping land or demanding working depth requirements, a tractor with stronger traction, sufficient operating weight and suitable hydraulic capacity should be selected. Four-wheel drive tractors are generally more suitable for wider models and heavier field conditions.
Recommended BSM Tractor Matching
Different tractor power levels correspond to different 1BJ working widths and field workloads. The following BSM tractor options can be used as reference points when selecting a complete tractor and disc harrow solution.
- 70HP Tractor: The 70HP tractor is positioned mainly for mixed farming and medium farm operations. It may be considered near the lower end of hydraulic folding harrow applications only after confirming actual implement weight, hydraulic requirements and field conditions.

- 80HP Tractor: Suitable for medium farms that require wider soil preparation than typical mounted harrows. The 80HP class can be considered for suitable 1BJ configurations after confirming tractor weight, hydraulic output and soil resistance. View BSM 80HP 4WD Farm Tractor
- 90HP Tractor: Suitable for medium and larger farms requiring stronger traction and broader implement compatibility. A 90HP tractor is a practical option for suitable mid-range 1BJ models depending on field and hydraulic conditions. View BSM 90HP Farm Tractor
- 100HP Tractor: A strong match for medium and large farms requiring wider working widths, repeated field passes and longer daily working periods. The 100HP class is particularly relevant to the 1BJ-4.4 and selected 1BJ-4.8 configurations after technical confirmation. View BSM 100HP Agricultural Tractor with Air-Conditioned Cabin
- 120HP Tractor: Suitable for larger-field applications and wider hydraulic trailed harrows where higher pulling capacity and daily coverage are required. Final matching should be confirmed according to the selected disc harrow model, soil resistance and tractor specification. View BSM 120HP 4WD Farm Tractor
Why Hydraulic Folding Matters on Large Fields
As working width increases, field efficiency can improve because the tractor covers more land during each pass. However, very wide implements can become inconvenient during road transport, movement through farm entrances and transfer between separate fields.
The hydraulic folding structure is designed to balance these two requirements:
- Wider working width during field operation
- Reduced overall width during transport
This is one reason hydraulic folding disc harrows are more relevant to larger farms and commercial operators than compact mounted harrows.
100HP Cabin Tractor Application with Hydraulic Folding Disc Harrow
For buyers considering a 100HP tractor for longer working periods and larger fields, BSM has a dedicated application guide explaining why a cabin tractor and hydraulic folding disc harrow can form a practical combination for repeated soil preparation work.
The application focuses on working width, transport convenience, long daily operating periods, hydraulic capacity and field-to-field movement.

120HP Heavy Disc Harrow Application Reference
For even larger dryland operations, buyers can also review a 120HP tractor and heavy-duty disc harrow application reference.
This application focuses on stronger soil penetration, crop residue cutting, wider field coverage and large-scale dryland preparation. It represents a heavier working direction than the typical 80-100HP medium-farm configuration.

Hydraulic Folding vs Mounted Disc Harrow
A mounted disc harrow is normally more practical for smaller tractors, narrower working widths and small or medium farms. The tractor carries the implement through the three-point linkage, making the structure compact and flexible.
A hydraulic folding disc harrow is more suitable when the buyer requires:
- Wider working width
- Higher daily field capacity
- Medium or large commercial farm operation
- Hydraulic transport folding
- Regular movement between multiple fields
For smaller tractors and compact field operations, see the Mounted Light Duty Disc Harrow for 12-60HP Tractors.
For a detailed comparison of the two structures, read: Hydraulic Folding vs Mounted Disc Harrow: Which One Fits Your Farm?
Suitable Crops and Field Conditions
- Maize and corn fields
- Wheat fields
- Soybean fields
- Cotton-growing areas
- Large vegetable farms
- Dry farmland
- Previously ploughed medium soil
- Fields with crop residue
- Medium and large commercial farms
Actual working results depend on soil hardness, moisture, crop residue quantity, working depth, tractor traction, field slope and operating speed.

Frequently Asked Questions
What tractor horsepower is suitable for the 1BJ hydraulic folding disc harrow?
The BSM 1BJ Series is designed for approximately 45-160HP tractors. The final model depends on working width, implement weight, hydraulic configuration, soil condition and required working depth.
Why choose a hydraulic folding disc harrow?
The hydraulic folding structure allows a wider working width in the field while reducing overall machine width during transport. It is particularly useful for medium and large farms requiring higher daily field capacity.
What is the working depth?
The reference working depth is approximately 160-180mm. Actual depth depends on soil hardness, tractor traction, operating speed and disc adjustment.
What disc size does the 1BJ Series use?
The current 1BJ Series uses approximately 560mm or 22-inch concave disc blades with a reference thickness of approximately 4mm.
Is this a three-point mounted disc harrow?
No. The 1BJ Series uses a hydraulic trailed structure. The tractor should have suitable pulling capacity and compatible hydraulic connections.
Can a 100HP tractor use this disc harrow?
Yes. A suitable 100HP tractor can be matched with selected 1BJ models, such as the 1BJ-4.4 and some 1BJ-4.8 applications, subject to tractor weight, hydraulic configuration, soil resistance and required working conditions.
