C Series Heavy Duty Rotary Tiller PTO Driven for Tractor 50–90HP | CE Certified

Main Features of the C Series Heavy Duty Rotary Tiller

Heavy-Duty Cast Iron Gearbox

The gearbox is a critical part of any PTO-driven rotary tiller. The C Series is equipped with a heavy-duty cast iron gearbox designed to support stable torque transmission during field operation.

This robust gearbox construction helps the rotary tiller handle the power requirements of wider working widths and demanding soil cultivation tasks. The gearbox configuration can also be discussed as part of the available customization service.

PTO-Driven Operation

The product page specifies a 540 rpm PTO-driven system for efficient and smooth operation. The tiller connects to the tractor PTO shaft, allowing the tractor engine to power the rotary blade system.

Before ordering, customers should confirm the tractor PTO specification, available horsepower and required gearbox configuration to ensure that the selected rotary tiller matches the tractor correctly.

Side Gear Drive Structure

The C Series uses a side gear drive structure to transmit power to the blade rotor. Compared with a lighter-duty transmission arrangement, the side gear system is intended to provide dependable power transfer for wider and heavier rotary tillers.

The enclosed transmission structure also supports practical maintenance for professional agricultural operations.

Heat-Treated Replaceable Blades

The rotary tiller is fitted with heat-treated, replaceable blades for soil cutting and mixing. Replaceable blades allow worn components to be serviced without replacing the complete rotor assembly.

Both L-type and C-type blades are listed as available options. The suitable blade type should be selected according to the soil condition, crop residue, cultivation objective and local operating requirements.

Category II Three-Point Hitch

The C Series rotary tiller uses a Category II three-point hitch for tractor mounting. This connection system is commonly used with medium and large agricultural tractors.

Correct hitch adjustment helps maintain a suitable working position, operating depth and machine balance. Tractor compatibility should be checked using the model power range, hitch category, PTO specification and lifting capacity.

Wide Working Width

The CSP250 has a listed working width of 260 cm, while the CSP300 provides a working width of 310 cm.

These widths allow the C Series to cover substantial field areas during each operating pass. The CSP300 is particularly suitable for buyers prioritizing wider coverage, provided that the tractor meets the corresponding power and mounting requirements.

CSP250 and CSP300 Model Comparison

CSP250 Rotary Tiller

The CSP250 is the smaller model in the C Series. It is designed for tractors within the listed 80–130 HP range and provides a 260 cm working width.

With 60 blades and a machine weight of 829 kg, it is suitable for general farmland preparation where a wide working area is required without moving to the larger CSP300 configuration.

The CSP250 may be considered for:

• General soil preparation

• Seedbed preparation

• Routine field cultivation

• Crop residue incorporation

• Farms requiring a 260 cm working width

CSP300 Rotary Tiller

The CSP300 is the wider and heavier model. It is designed for tractors within the listed 100–130 HP range and offers a 310 cm working width.

The machine has 72 blades and a listed weight of 940 kg. Its wider structure allows more ground to be covered during each pass, making it suitable for larger fields and higher-volume cultivation work.

The CSP300 may be considered for:

• Large-area field cultivation

• Wider seedbed preparation

• Professional agricultural contracting

• Intensive soil preparation

• Operations requiring higher coverage efficiency

Agricultural Applications

Soil Preparation

The C Series rotary tiller can be used to loosen and break up soil before subsequent farming operations. Rotating blades work across the soil profile to create a more workable surface for planting and field management.

The required working depth and operating speed should be adjusted according to soil condition, tractor capability and cultivation objectives.

Seedbed Preparation

A consistent seedbed supports more uniform planting conditions. The CSP250 and CSP300 can be used after primary tillage to break larger soil clods and prepare the upper soil layer.

The final soil condition will depend on factors including moisture, soil composition, blade selection, travel speed and the number of operating passes.

Field Cultivation

The wide working widths make the C Series suitable for regular cultivation across medium and large fields. Farmers and contractors can choose between the 260 cm and 310 cm models based on field size, tractor horsepower and required operating efficiency.

Stubble Breaking

After crop harvesting, the rotary blades can help break down remaining stubble and surface residue. This supports subsequent field preparation and helps distribute residue through the cultivated soil layer.

Residue Mixing

The machine can mix crop residue with loosened soil during rotary cultivation. This application is useful where farmers need to manage surface material before the next planting or land preparation stage.
