Farm Implement Buying Guide | HENAN BEST Machinery (BSM)
A mounted disc harrow and a hydraulic folding disc harrow can both be used for breaking soil clods, mixing crop residue, loosening cultivated soil and preparing a seedbed before planting.
However, the two structures are designed for different tractor power ranges, farm sizes, transport conditions and daily working requirements. A mounted disc harrow is normally more practical for small and medium farms, while a hydraulic folding disc harrow is often selected for wider working widths, higher field capacity and easier transport between large fields.
This guide compares the main differences between mounted and hydraulic folding disc harrows and explains how farmers, contractors and machinery dealers can select a suitable model.
A mounted disc harrow connects directly to the tractor through a three-point linkage. The tractor hydraulic system lifts the entire implement during field turning, transport and storage.
Mounted disc harrows normally have a compact structure and are suitable for small or medium working widths. They are commonly used with compact and utility tractors on small farms, orchards, vegetable fields and general cultivated farmland.
HENAN BEST Machinery (BSM) currently supplies two main mounted disc harrow options:
A hydraulic folding disc harrow normally uses a trailed connection and hydraulic control. Its working sections can be folded for transport and opened in the field to provide a wider working width.
This structure is more suitable for medium and large farms that need higher daily field capacity. Hydraulic folding also reduces transport width, making it easier to move the machine between fields, along farm roads or into storage areas.
The BSM 1BJ Series Hydraulic Folding Disc Harrow for 45–160HP Tractors is available with working widths from approximately 2.0m to 6.0m. It uses a reinforced frame, 560mm concave discs and a hydraulic trailed structure for medium and large-area soil preparation.
| Comparison Item | Mounted Disc Harrow | Hydraulic Folding Disc Harrow |
|---|---|---|
| Connection Type | Three-point mounted | Hydraulic trailed |
| Typical Tractor Power | Approximately 12–75HP | Approximately 45–160HP |
| Working Width | Normally narrow to medium | Medium to very wide |
| Farm Size | Small and medium farms | Medium and large farms |
| Hydraulic Requirement | Requires sufficient rear lifting capacity | Requires suitable hydraulic connections and pulling capacity |
| Field Turning | Compact and flexible | Requires more turning space |
| Road Transport | Simple for smaller models | Folding sections help reduce transport width |
| Daily Field Capacity | Suitable for normal farm work | Suitable for higher daily working requirements |
| Purchase Cost | Normally lower | Normally higher due to size and hydraulic structure |
| Best Application | Small fields, orchards and general secondary tillage | Large fields, wide working widths and commercial operations |
A mounted light duty disc harrow is suitable when the tractor is relatively small and the soil has already been cultivated. It is designed for shallow to medium secondary tillage rather than heavy primary soil breaking.
It is a practical option for:
- 12–60HP compact and utility tractors
- Small family farms
- Vegetable fields
- Orchards and narrow plots
- Loose or previously cultivated soil
- Light crop residue
- Seedbed preparation after ploughing
Its lower weight makes field turning and transport easier. However, it may not provide enough penetration for hard, dry or heavily compacted soil.

A mounted medium duty disc harrow provides a balance between implement weight, soil penetration and working efficiency.
It is suitable for tractors in the approximate 35–75HP range and can be used for more demanding secondary tillage than a light duty model.
Typical applications include:
- Maize and wheat fields
- Soybean and mixed-crop farms
- Previously ploughed medium soil
- Moderate crop residue
- Small and medium commercial farms
- General clod breaking and field leveling
Before ordering, buyers should confirm the tractor's rear lifting capacity, three-point linkage category, operating weight and 2WD or 4WD configuration.

A hydraulic folding disc harrow is suitable when field size, daily working capacity and transport convenience are more important than compact dimensions.
It is normally recommended for:
- Medium and large commercial farms
- 45–160HP tractors
- Wide-area seedbed preparation
- Fields with crop residue
- Maize, wheat, soybean and cotton production
- Agricultural contractors
- Farms that require transport between multiple fields
- Buyers who need higher daily working efficiency
The BSM 1BJ Series includes working widths of approximately 2.0m, 4.4m, 4.8m, 5.3m and 6.0m. The correct model should be selected according to tractor power, tractor weight, hydraulic configuration, soil hardness and required working depth.

Tractor horsepower is an important reference, but it should not be used alone. Two tractors with the same horsepower may have different weights, hydraulic systems, lifting capacities, tire sizes and traction performance.
| Tractor Power | Suggested Disc Harrow Structure | Typical Application |
|---|---|---|
| 12–30HP | Small mounted light duty disc harrow | Gardens, orchards and small cultivated plots |
| 30–60HP | Mounted light or compact medium duty disc harrow | Small and medium farms |
| 60–75HP | Mounted medium duty or compact hydraulic trailed model | General field preparation and residue mixing |
| 75–120HP | Hydraulic folding or heavier trailed disc harrow | Medium and large commercial farms |
| 120–160HP | Wide hydraulic folding disc harrow | Large-area land preparation and high daily capacity |
The ranges above are general references. Final matching depends on implement weight, working width, soil resistance, field slope and tractor hydraulic configuration.
Mounted and hydraulic folding disc harrows use the tractor hydraulic system in different ways.
A mounted disc harrow requires enough rear lifting capacity to raise the complete implement. If the implement is too heavy, the tractor may become unstable or fail to lift it safely.
A hydraulic folding disc harrow is trailed, so the tractor does not lift the entire machine through the three-point hitch. However, it still requires suitable hydraulic connections to control the folding sections and transport system.
Buyers should provide hydraulic pressure, oil flow, connection type and available hydraulic outlets before confirming a hydraulic folding model.
A mounted disc harrow is normally more suitable for small, narrow or irregular fields.
Its compact size allows the tractor to turn more easily at field boundaries, operate near trees or irrigation channels and move through narrow entrances.
A wide hydraulic folding disc harrow requires more turning space. It is more efficient on large, open and regularly shaped fields.
A hydraulic folding disc harrow usually provides higher theoretical field capacity because of its wider working width.
For example, a 4.8m or 6.0m model can cover considerably more land in one pass than a small mounted model. This can reduce repeated passes, operator time and total working days during the planting season.
However, a wide implement only improves efficiency when the tractor has enough pulling power and the field allows a suitable operating speed. An oversized model may increase wheel slip, fuel consumption and turning time.
Transport width is an important factor for buyers who move machinery between fields or use public roads.
Small mounted disc harrows are relatively easy to transport, but larger mounted models remain limited by tractor lifting capacity.
Hydraulic folding models can reduce their overall width during transport. This makes wide implements more practical for road movement, farm entrances and storage.
Buyers should still confirm the folded width, total machine weight, transport wheel configuration and local road requirements before ordering.
| Field Condition | Suggested Structure | Reason |
|---|---|---|
| Loose or Previously Cultivated Soil | Mounted light duty disc harrow | Lower weight is normally sufficient for shallow preparation |
| Medium Soil | Mounted medium duty disc harrow | Provides a balance between penetration and tractor load |
| Large Open Field | Hydraulic folding disc harrow | Wide working width improves daily field capacity |
| Heavy Crop Residue | Medium duty or hydraulic folding disc harrow | Stronger frame and larger working structure improve residue mixing |
| Narrow or Irregular Field | Mounted disc harrow | Compact structure improves maneuverability |
| Multiple Fields Requiring Road Transport | Hydraulic folding disc harrow | Foldable sections reduce transport width |
- Choosing the widest model only to increase theoretical efficiency
- Ignoring tractor weight and traction
- Failing to confirm rear lifting capacity for a mounted model
- Failing to confirm hydraulic outlets for a folding model
- Using a wide trailed model in a very small field
- Selecting a light duty model for difficult soil conditions
- Ignoring folded transport width and machine weight
- Not considering replacement disc blades and bearings

It is not better for every farm. Hydraulic folding models are more suitable for wide working widths and large fields. Mounted models are more practical for smaller tractors, narrow fields and farms with limited turning space.
A suitable compact hydraulic folding model may be considered, but tractor weight, hydraulic output, soil conditions and required working width must be confirmed. A mounted light or medium duty model may be more practical for many 50HP tractors.
Yes. A properly configured 70HP tractor can work with a suitable mounted medium duty model. Rear lifting capacity, implement weight and soil resistance should still be checked.
Four-wheel drive is not mandatory for every model, but it normally provides better traction and stability when working with wider or heavier equipment, especially on loose, uneven or hard soil.
Yes. HENAN BEST Machinery (BSM) can supply disc blades, bearings and selected wearing parts with the implement order.
