3Z Row Crop Cultivator and Ridger for 20-55HP Tractors

The BSM 3Z Series Row Crop Cultivator and Ridger is designed for agricultural tractors from approximately 20HP to 55HP. It combines inter-row cultivation, soil loosening, weed control, furrow opening and ridging in one tractor-mounted implement.

Unlike a general-purpose agricultural cultivator, the 3Z Series is specifically designed for crops planted in regular rows. Its working units can be adjusted according to crop row spacing, tractor wheel track and local planting methods.

Three models are currently available: 3Z-2, 3Z-3 and 3Z-4. The series covers working widths from approximately 1500mm to 3700mm, with 3-5 cultivation rows and 2-4 ridging rows.

• Inter-row cultivation for row crops
• Soil loosening between crop rows
• Mechanical weed control
• Furrow opening
• Ridging around crop rows
• Breaking light surface compaction
• Improving soil aeration
• Improving water infiltration
• Maintaining cultivated row-crop fields
• Preparing or maintaining ridges for suitable crops

• Corn and maize
• Soybean
• Cotton
• Sweet potato
• Other crops planted in regular rows

The 3Z cultivator connects to the tractor through a rear three-point hitch. During operation, the working tips move through the soil between crop rows.

The working units loosen the upper soil layer, disturb weeds and improve aeration around the crop root zone.

Depending on the selected working layout, the rear sections can also open furrows or move soil toward the crop rows to form ridges.

The row spacing can be adjusted from approximately 450mm to 600mm, allowing the machine to adapt to different planting patterns and tractor wheel tracks.

• Multiple Functions in One Implement: Supports inter-row cultivation, soil loosening, weeding, furrowing and ridging.
• Adjustable Row Spacing: Working units can be adjusted for approximately 450-600mm crop row spacing.
• Three Model Options: 3Z-2, 3Z-3 and 3Z-4 cover different tractor power and field-size requirements.
• 3-5 Cultivation Rows: Different models can cultivate three, four or five row spaces.
• 2-4 Ridging Rows: The ridging layout varies according to the selected model.
• 1500-3700mm Working Width: Different models provide different total field coverage.
• Three-Point Mounted Structure: Connects directly to a compatible agricultural tractor.
• Lightweight Design: Machine weight ranges from approximately 95kg to 140kg, reducing rear lifting requirements compared with heavier tillage implements.
• Suitable for Row Crops: Designed for corn, soybean, cotton, sweet potato and similar crops.
• OEM Support: BSM can customize color, logo and selected working-unit configurations.

All current 3Z models use a three-point mounted tractor connection. The specifications above should be used together with crop row spacing, tractor wheel track, rear lifting capacity and actual field conditions before final model selection.

Tractor horsepower is only one part of the selection process. Buyers should also check tractor rear lifting capacity, tractor wheel track, crop row spacing, field shape and required cultivation width.

The 3Z-2 is the most compact model in the current series. It provides approximately 1500mm working width, three cultivation rows and two ridging rows.

The machine weighs approximately 95kg and is designed for tractors from approximately 20HP to 30HP.

This configuration is suitable for small farms, narrow fields, vegetable production areas and row crops where compact tractor maneuverability is important.

The 3Z-3 provides approximately 2900mm working width, four cultivation rows and three ridging rows.

The machine weighs approximately 115kg and is designed for tractors from approximately 35HP to 45HP.

It provides higher field capacity than the 3Z-2 while remaining suitable for medium-scale row-crop farming.

The 3Z-4 is the widest current model, providing approximately 3700mm working width, five cultivation rows and four ridging rows.

The machine weighs approximately 140kg and is designed for tractors from approximately 45HP to 55HP.

It is suitable for wider row-crop fields where higher daily cultivation capacity is required.

A compact tractor around 25HP is a natural match for the 3Z-2 configuration.

Before operation, tractor tire spacing should be adjusted so that the tires remain outside the crop rows.

Tractors in the 35-45HP range can be matched with the 3Z-3 for four-row cultivation when rear lifting capacity and row spacing are suitable.

A 50HP tractor is well positioned for the 3Z-4 power range and can support wider five-row cultivation when tractor wheel track and crop spacing are correctly matched.

The current 3Z Series supports approximately 450-600mm adjustable row spacing.

This adjustment is important because crop planting distances vary between regions, crop varieties and local farming methods.

Before field operation, the working units should be positioned according to the actual crop rows.

Adequate clearance must be maintained between the working tips and crop roots to reduce the risk of plant damage.

The tractor tires must travel between crop rows without running over the plants.

For this reason, tractor rear wheel track and cultivator working-unit spacing should be considered together.

A cultivator with the correct row spacing but an unsuitable tractor wheel track may still damage crops during inter-row operation.

The BSM 3Z Series and the general BSM Agricultural Cultivator serve different working requirements.

For buyers who need a broader general-purpose cultivator for tractors up to approximately 100HP:

The 3Z Series can loosen soil, control weeds and maintain ridges between corn or maize rows.

The working units should be adjusted according to actual planting distance.

As the crop grows, working depth and distance from the plant row should be controlled more carefully to avoid root damage.

Inter-row cultivation can help disturb weeds, break surface compaction and improve air circulation around soybean root zones.

The cultivator should operate only when row spacing and crop development stage provide sufficient clearance.

The adjustable 450-600mm row-spacing range allows the machine to adapt to different cotton planting layouts.

Working units should be positioned carefully before entering the field to maintain sufficient clearance from the plants.

The ridging function can be used to prepare or maintain raised soil rows for sweet potato cultivation when the selected configuration matches local planting methods.

Ridge shape and soil movement depend on soil moisture, working-unit setup and tractor forward speed.

Yes. The machine is designed for inter-row field maintenance after crop emergence when sufficient row clearance is available.

However, the operator must carefully control:

• Working depth
• Distance from crop roots
• Tractor wheel track
• Working-unit spacing
• Forward speed
• Crop growth stage

The 3Z Series is suitable for cultivated dry farmland where row crops are planted in regular patterns.

The machine performs best after primary and secondary soil preparation have already been completed.

Heavy long straw or large amounts of residue should be managed before inter-row cultivation to reduce blockage around the working units.

A typical row-crop production process can include:

1. Primary tillage: plough or suitable primary tillage implement
2. Secondary soil preparation: disc harrow or rotary tiller
3. Planting: corn planter or suitable row-crop planter
4. After emergence: 3Z cultivator for inter-row loosening, weed control and ridging

The current BSM 3Z Series is designed for tractors from approximately 20HP to 55HP.

The 3Z-2 matches approximately 20-30HP, the 3Z-3 approximately 35-45HP and the 3Z-4 approximately 45-55HP.

Yes. The working units can be adjusted for approximately 450-600mm row spacing.

Yes. The current 3Z Series supports both inter-row cultivation and ridging.

The 3Z-2 provides two ridging rows, the 3Z-3 provides three and the 3Z-4 provides four.

The machine is suitable for corn, soybean, cotton, sweet potato and other crops planted in regular rows.

The 3Z Series works through tractor traction and does not normally require PTO power for standard inter-row cultivation and ridging.
