Power Harrows for Tractor

Power harrows or round-grass harrows are agricultural equipment for tillage. Used mainly to prepare the ground for sowing these machines are connected to tractors and perform the task of breaking and levelling the soil. Available in a variety of series, power harrows adapt to a variety of agricultural needs, varying in weight, strength and technical specifications.

• Extra-light Series Power Harrows: Suitable for low-power tractors, they are ideal for light work.
• Light Series Power Harrows: Machines built for less powerful tractors, perfect for less intensive use.
• Medium Series: Robust equipment for most non-heavy farm work.
• Heavy Series Tractor-mounted Power Harrows: Designed for powerful tractors that are ideal for intense and heavy farming operations.

The power harrow is an agricultural machine used for tillage. The power harrow is a piece of equipment dragged by the tractor, widely used in agriculture for working large soils but also in vineyards and orchards.

The power harrow is used to refine the soil before sowing, or to control the weeds in orchards. This machine is essential for good sprouting and crop growth due to its ability to break up clods of soil and create an optimal seedbed.

However, it is worth remembering that this tool cannot replace the tasks of a tiller.

The harrow, working the top layer of the soil and reducing the size of the soil clods, manages to mix the crop residues and make the surface more homogeneous. Other purposes for which it is used are:

• To bury the seeds after sowing;
• To bury pre-sowing mineral fertilizers;
• To bury volatile herbicides;
• Break the surface of the hardened soil;
• Make the surface more even.

The power harrow consist of a series of rotors equipped with blades or knives. These machines are connected to tractors and use the power of the tractor to operate.

The classic harrow model may also be considered as a "clod breaker" thanks to its main function. It can be:

• Pulled by the tractor. In this case it consists of a drawbar where it is attached to the hitch of the tractor, the wheels where the whole structure rests, and finally a base that rises and falls using a hydraulic jack;
• Dragged by another machine, connecting it with the 3-point hitch. The dragged harrow is fitted to the hydraulic lift and only needs to be lowered to operate it.

The main components of the power harrows are as follows:

• Frame: a load-bearing structure that connects the implement to the tractor.
• Rotors: Equipped with reversible blades or knives, the rotors work the soil by breaking up the clods.
• Rollers: They vary in type and function, including cage rollers, spike rollers, packer rollers and net rollers.
• Adjustable refining bar: Enables more efficient grinding of soil clods.

Harrowing is usually carried out after ploughing and before sowing. Generally, however, everything is based on sowing, so the harrowing period may vary.

However, a good practice is to leave the soil clods exposed to the air for a limited period of time. If too much time passes between ploughing and sowing, it is better to use the action of the weather to break up the clods and then move on to harrowing closer in time to the sowing. All in all, it is recommended to use the harrow close to the sowing period.

Power harrows offer numerous advantages over other soil preparation methods. Their ability to break and level the soil in a single pass significantly reduces the time and effort required to prepare it.

• Efficiency: They allow working on large surfaces in a short time.
• Quality of processing: They ensure an even and well-prepared soil for sowing.
• Versatility: Suitable for different soil types and agricultural conditions.

Power harrows are divided into different types, each one tailored to specific requirements and working conditions. Here is an overview of the different power harrow series available:

• Heavy Series: Compatible with very powerful tractors (75-100 HP), these power harrows are designed for intensive work in hard, compact soils. Their strength and heavy weight allow for deep penetration and effective tillage.

The type of roller fitted to the power harrow has a major influence on the quality of the soil tillage.

• Cage roller: This roller is made of a tubular structure that lightly compresses the soil while aerating it. It is ideal for preventing hard crust from forming on the soil by promoting good aeration and water penetration.
• Packer roller: Designed for shredding and compacting soil, this roller is ideal for creating a smooth, well-compacted seedbed. It is especially useful for crops that require finely processed soil.
• Spike roller: Equipped with protruding spikes, this roller performs coarser tilling of the soil, perfect for the first passage on hard ground. It helps break up the larger soil clods and facilitates further soil refinement.
• Net roller: This roller prepares the soil for vegetable sowing by creating a well-structured surface suitable for plant growth. The net prevents excessive compacting by keeping the soil soft.

The adjustable refinement bar is a key component in the quality of tillage. It improves clod grinding by adjusting the depth and intensity of processing. This component ensures that the soil is finely ground and well-prepared for sowing, reducing the possibility of hard clods that could hinder plant sprouting.

The maximum power of the tractor compatible with the power harrow is a critical parameter. It indicates the maximum power capacity that the harrow can withstand without being damaged. Using a tractor with the right power will prevent overloading and damage to the harrow, ensuring long machine life and efficient operation.

The working width of a power harrow determines how much surface can be covered in a single pass. A larger working width allows you to cover large areas in less time, increasing operational efficiency, especially in large agricultural fields.

The type of blade or knife used in the power harrow affects the quality and effectiveness of the tillage.

• Rotor with blades: Fixed or rotating blades that slit and break up the soil.
• Reversible knives: These knives can be reversed to extend their service life. They are essential to reduce maintenance costs and ensure that your soil is always processed efficiently.

The number of rotors in a power harrow, ranging from 5 to 11, determines the tillage capacity. More rotors allow finer and more even tilling of the soil, improving seedbed preparation.

The amount of knives fitted to each rotor, ranging from 10 to 22, directly influences tillage efficiency. More rotor knives allow for more intensive and detailed processing ensuring the ground is well broken up and prepared for seeding.

The power harrow is an agricultural tool used for preparing the soil before sowing. It consists of a series of discs or tines mounted on a rotating axle connected to the tractor's PTO. This tool is particularly effective for tillage because it breaks soil clods and makes it finer and smoother, facilitating even sowing.

A power harrow's main components are:

• Frame: a load-bearing structure that connects the implement to the tractor.
• Tines or discs: rotating elements that work the ground.
• Rear roller: composes and levels the worked soil.

The power harrow is used for several purposes:

• Seedbed preparation: creates fine, even soil.
• Incorporation of crop residues: mixes straw and other residues in the soil.
• Breaking up clods: reduces the size of soil clods.

The power harrow works by delivering power from the tractor via the PTO. The tractor crankshaft rotates the harrow axles on which the tines or discs are fitted. These rotating elements penetrate the ground, breaking and levelling it.

The main operational steps are:

• Connecting to the tractor: the harrow is hitched to the tractor by a three-point hitch.
• Activation of the PTO: the tractor power is transferred to the harrow.
• Depth adjustment: the rear roller and the stabilizing wheels control the working depth.

Adjusting a power harrow is essential to achieve optimum tillage. Here are the main factors to consider:

• Working depth: Adjust the rear roller or support wheels to set the desired depth.
• Tine angle: Some models allow the angle of the tines to be adjusted to suit different types of soil.
• Rotation speed: The tractor PTO speed affects the rotational speed of the tines.

Adjustment steps:

• Set the rear roller: Adjust the roller to check the working depth.
• Adjust the angle of the tines: If possible, change the angle to optimize the machining.
• Check the PTO speed: Adapt the speed to the ground conditions.

Choosing of a power harrow depends on various factors that influence the effectiveness and efficiency of agricultural work. Here's what to consider:

• Working width: It determines the amount of soil worked in a pass. Choose a width that is appropriate for the field size and the power of the tractor.
• Tine number: More tines mean a finer processing. Consider the type of soil you will be working on.
• Tractor power: Make sure the harrow is compatible with the power of your tractor.
• Working depth: Check the harrow's ability to work at different depths.
• Quality of materials: A harrow made of durable materials ensures durability and reliability.

Power harrow oil is essential to ensure proper operation and tool durability. Power harrows require oil for the lubrication of their moving components, especially the gearbox. Using the correct type of oil is essential to avoid wear and damage.

The main types of oil used are:

• Gear oil: Specific oil for the lubrication of the internal gears. Usually an SAE 80W-90 oil is appropriate.
• Hydraulic oil: Used in the hydraulic systems of some power harrows. Make sure to use the manufacturer's recommended type of hydraulic oil.

Oil change procedure:

• Check the oil level: Check the oil level through the oil level indicator light or dipstick.
• Draining the old oil: Remove the drain plug in order to drain the used oil into a suitable container.
• Filling with new oil: Pour in the new oil to the recommended level using the oil specified in the harrow operating instructions.

There are different types of power harrows, each designed for specific tillage needs. The main types include:
