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 farmland before planting.
However, the two structures are designed for different tractor sizes, field conditions, working widths, transport requirements and daily workloads. A compact mounted disc harrow is generally more practical for smaller tractors and smaller fields, while a hydraulic folding disc harrow is designed for wider working widths, larger fields and higher daily field capacity.
This guide explains the main differences between mounted and hydraulic folding disc harrows and helps farmers, agricultural contractors and machinery dealers select a suitable structure according to tractor specification and actual farm conditions.
What Is a Mounted Disc Harrow?
A mounted disc harrow connects directly to the tractor through a rear three-point linkage. The tractor hydraulic system lifts the complete implement during turning, transport and storage.
Mounted disc harrows normally have a compact structure and relatively limited working width. They are commonly used with compact and utility tractors on small farms, orchards, vegetable fields and previously cultivated farmland.
For current BSM mounted disc harrow applications, buyers using smaller tractors can consider the light-duty mounted structure.

What Is a Hydraulic Folding Disc Harrow?
A hydraulic folding disc harrow normally uses a trailed structure with hydraulic control. The working sections can be opened during field operation and folded to reduce overall transport width.
This design is more suitable for medium and large farms where wider soil preparation and higher daily field capacity are required. Hydraulic folding also makes a wider implement more practical when moving between fields, passing through farm entrances or entering storage areas.
The BSM 1BJ Series Hydraulic Folding Disc Harrow is designed for tractors from approximately 45HP to 160HP, with working widths from approximately 2.0m to 6.0m depending on model. The series uses 560mm disc blades and a reinforced hydraulic trailed structure for medium and large-area secondary soil preparation.

When Should You Choose a Mounted Light Duty Disc Harrow?
A mounted light-duty disc harrow is suitable when the tractor is relatively compact and the soil has already received primary tillage. Its main role is secondary soil preparation rather than difficult primary soil breaking.
Typical applications include:
- 12-60HP compact and utility tractors
- Small family farms
- Vegetable fields
- Orchards and narrow fields
- Loose or previously cultivated soil
- Light crop residue
- Clod breaking after ploughing
- Seedbed preparation before planting
Its relatively compact structure can make turning, three-point lifting and transport easier than with larger implements.
However, a light-duty structure should not be selected simply because it requires less tractor power. Hard, dry, heavily compacted or residue-heavy soil may require a different tillage strategy or a heavier soil preparation structure.

When Does a Heavier Disc Harrow Structure Make Sense?
A heavier disc harrow structure may be required when the farm needs stronger penetration, greater residue handling or higher field capacity than a small light-duty mounted harrow can provide.
Instead of selecting an implement only by the label "light" or "heavy", buyers should evaluate actual working conditions, including:
- Soil hardness
- Soil moisture
- Crop residue level
- Required working depth
- Required working width
- Tractor operating weight
- Rear lifting capacity
- Available hydraulic system
- Available pulling traction
For medium and large tractors that require wider field coverage, a hydraulic folding disc harrow can provide a more suitable direction than trying to increase the size of a compact mounted implement.

When Should You Choose a Hydraulic Folding Disc Harrow?
A hydraulic folding disc harrow is suitable when field size, daily working capacity and transport convenience are more important than compact dimensions.
Typical applications include:
- Medium and large commercial farms
- Suitable tractors within approximately 45-160HP
- Wide-area secondary soil preparation
- Fields with crop residue
- Maize production
- Wheat production
- Soybean farming
- Cotton production
- Agricultural contracting
- Farms with multiple separated fields
- Operations requiring higher daily field capacity
The BSM 1BJ Series includes working widths of approximately 2.0m, 4.4m, 4.8m, 5.3m and 6.0m depending on model.
The correct model must be selected according to tractor power, tractor operating weight, hydraulic configuration, soil resistance, desired working depth and required field capacity.

How Tractor Horsepower Affects Disc Harrow Selection
Tractor horsepower is an important reference, but horsepower alone is not enough to determine the correct disc harrow.
Two tractors with the same horsepower may have different operating weights, hydraulic systems, rear lifting capacities, tire sizes, wheelbase and traction performance.
| Tractor Power | Suggested Direction | Typical Application |
|---|---|---|
| 12-30HP | Small mounted light-duty disc harrow | Gardens, orchards and small cultivated fields |
| 30-50HP | Mounted light-duty disc harrow | Small farms and regular secondary soil preparation |
| 50-60HP | Mounted light-duty or carefully selected compact hydraulic configuration | Small-medium farms and prepared soil |
| 60-75HP | Suitable compact hydraulic trailed/folding configuration after matching verification | Medium farm field preparation and residue mixing |
| 75-100HP | Hydraulic folding disc harrow | Medium and larger commercial farms |
| 100-120HP | Medium-width hydraulic folding disc harrow | Large fields and higher daily field capacity |
| 120-160HP | Wide hydraulic folding disc harrow | Large-area soil preparation |
These ranges are reference directions rather than fixed matching rules. Final selection depends on machine weight, working width, soil resistance, field slope, hydraulic specification and tractor operating weight.
Can a 50HP Tractor Use a Hydraulic Folding Disc Harrow?
The BSM hydraulic folding disc harrow range begins at approximately 45HP, so a compact configuration may technically fall within the power range of some 50HP tractors.
However, this does not mean every 50HP tractor should use a folding disc harrow. Tractor operating weight, hydraulic output, pulling traction, soil resistance and implement weight must all be confirmed before selecting the machine.
For lighter secondary tillage on small and medium farms, the mounted light-duty disc harrow may often be the simpler and more practical choice.

Can a 70HP Tractor Use a Hydraulic Folding Disc Harrow?
A 70HP tractor is within the stated power range of the BSM hydraulic folding disc harrow, but it is still toward the lower side of the complete 45-160HP range.
A compact suitable model may be considered after confirming tractor operating weight, hydraulic output, pulling traction, implement weight and actual field conditions.
For 70HP applications, buyers should avoid selecting a wide folding model based only on theoretical working width. The smallest suitable configuration is usually the first direction to evaluate.

How Does an 80HP Tractor Match a Hydraulic Folding Disc Harrow?
An 80HP 4WD tractor provides more traction and operating weight than smaller utility tractors, making it a more natural starting point for selected hydraulic folding configurations.
Final working width should still be determined according to implement weight, field resistance, hydraulic system, working depth and the required daily field area.

How Does a 100HP Tractor Match a Hydraulic Folding Disc Harrow?
A 100HP tractor is suitable for medium and large farm operations where wider secondary tillage and longer daily working periods are required.
Within the BSM folding disc harrow range, a 100HP tractor can be evaluated with appropriate medium-width configurations after confirming tractor weight, hydraulic connections, soil conditions and required working depth.

Why Tractor Hydraulic Capacity Matters
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 fail to lift it properly or may become unstable during turning and transport.
A hydraulic folding disc harrow uses a trailed structure, so the complete machine is not carried by the tractor three-point hitch. However, suitable hydraulic connections are still required to control folding and related hydraulic functions.
Before ordering a hydraulic folding model, buyers should provide available hydraulic outlet information and relevant tractor hydraulic specifications.
Which Type Is Better for Small or Irregular Fields?
A compact mounted disc harrow is normally more suitable for small, narrow or irregular fields.
Its smaller overall structure allows easier turning at field boundaries, movement near trees or irrigation channels and access through narrower field entrances.
A hydraulic folding disc harrow requires more operating space and is normally more efficient on large, open and regularly shaped fields.
Which Type Provides Higher Field Efficiency?
A hydraulic folding disc harrow can provide higher theoretical field capacity because wider models cover more land during each pass.
For example, a 4.8m or 6.0m model can cover more ground per pass than a compact mounted disc harrow when operating speed and field conditions are suitable.
However, wider does not automatically mean more efficient. If the tractor does not have enough traction, an oversized implement may increase wheel slip, fuel consumption, turning time and operating stress.
The correct goal is not to choose the widest possible machine, but to choose the widest implement that the tractor can operate efficiently under the actual soil and field conditions.
Transport and Storage Considerations
Transport width is an important consideration when agricultural machinery must move between multiple fields, through narrow farm entrances or along roads.
Compact mounted disc harrows are relatively simple to transport because their working width is limited.
Hydraulic folding disc harrows can reduce overall machine width during transport by folding the working sections. This is one of their main advantages when a wide working machine must move between fields.
Buyers should still confirm:
- Folded transport width
- Total machine weight
- Transport wheel configuration
- Tractor towing capacity
- Local road and transport requirements
How Soil Conditions Affect the Decision
| Field Condition | Suggested Direction | Reason |
|---|---|---|
| Loose or Previously Cultivated Soil | Mounted light-duty disc harrow | Lower implement weight may be sufficient for secondary preparation |
| Small Field with Light Residue | Mounted light-duty disc harrow | Compact structure provides better maneuverability |
| Medium Open Field | Compact suitable hydraulic folding configuration | Wider working width can improve field capacity |
| Large Open Field | Hydraulic folding disc harrow | Wide working width supports higher daily productivity |
| Moderate to Heavy Crop Residue | Suitable hydraulic folding disc harrow after matching verification | Larger working structure can improve residue mixing |
| Narrow or Irregular Field | Compact mounted disc harrow | Smaller structure improves maneuverability |
| Multiple Fields Requiring Transport | Hydraulic folding disc harrow | Foldable sections help reduce transport width |

Frequently Asked Questions
Is a Hydraulic Folding Disc Harrow Better Than a Mounted Disc Harrow?
Not for every farm. A hydraulic folding model is more suitable when wide working width, large field size and higher daily capacity are required.
A mounted light-duty model is more practical for smaller tractors, smaller fields, narrow entrances and applications where compact maneuverability is important.
Can a 50HP Tractor Use a Hydraulic Folding Disc Harrow?
A compact suitable configuration may be considered because the BSM hydraulic folding range begins at approximately 45HP. However, tractor weight, hydraulic output, soil conditions, pulling traction and implement weight must all be confirmed.
For many 50HP applications involving lighter secondary tillage, a mounted light-duty disc harrow may be the more practical choice.
Can a 70HP Tractor Use a Hydraulic Folding Disc Harrow?
Yes, a suitable compact configuration may be considered. However, 70HP is still toward the lower part of the BSM 45-160HP range, so tractor operating weight, hydraulic configuration, soil resistance and implement weight must be checked before selection.
Does a Hydraulic Folding Disc Harrow Require a 4WD Tractor?
4WD is not mandatory for every configuration, but four-wheel drive generally provides better traction and stability when operating wider or heavier implements, especially in loose, uneven or higher-resistance soil.
Can BSM Supply Disc Blades and Bearings?
Yes. HENAN BEST Machinery (BSM) can provide disc blades, bearings and selected wearing parts according to the implement configuration and order requirements.
