Rotary Drum Mower (DM130) for Cutting Hay and Grass

A tractor 3-point hitch rotary drum mower is an agricultural implement designed for efficient cutting of grass, hay, and other similar crops. This type of mower is connected to the tractor via the three-point hitch system, a standard method of attachment that provides a secure and adjustable link between the tractor and various implements. The rotary drum mower is distinct from other types of mowers, such as disc mowers, due to its use of rotating drums equipped with blades.

Design and Functionality

• Rotating Drums: Unlike disc mowers that use a series of spinning discs with attached blades, rotary drum mowers have one or more large drums. These drums rotate on a vertical axis and are equipped with fixed or free-swinging blades that cut the crop as the mower moves over the field.
• Three-Point Hitch Connection: The mower attaches to the tractor via a three-point hitch, which is a standard linkage system composed of three arms (two lower arms and one upper arm) that allows for quick attachment, easy adjustment, and stable operation. This system also enables the mower to follow the contour of the ground closely.
• Power Take-Off (PTO) Drive: Rotary drum mowers are powered by the tractor's PTO shaft, which transfers engine power to the mower. This setup eliminates the need for additional engines or power sources on the mower itself, leveraging the tractor's power for operation.

Tractor 3 Point Hitch Rotary Drum Mower Common Applications

A tractor 3-point hitch rotary drum mower is a versatile tool that can be used for a variety of applications related to cutting different types of vegetation. Here are the common applications for cutting specific crops and vegetation:

• Grass Cutting: Rotary drum mowers are widely used for cutting various types of grass, including lawn grass, pasture grass, and roadside grass. They provide efficient and uniform cutting, helping to maintain well-manicured lawns or tidy grassy areas.
• Hay Production: When it comes to hay production, rotary drum mowers are essential. They are used to cut and condition grasses or legumes like alfalfa, clover, or timothy, which are then dried and baled to produce high-quality hay for livestock feed.
• Crop Residue Management: After harvesting crops like corn, wheat, or rice, the remaining stalks and plant material need to be managed. Rotary drum mowers are effective in cutting and shredding crop residues, facilitating their decomposition and incorporation into the soil for improved nutrient cycling.
• Alfalfa Cutting: Alfalfa is a popular forage crop, and rotary drum mowers are commonly used for cutting alfalfa fields. The mowers provide a clean cut, promoting regrowth and maintaining the quality of the alfalfa for grazing or hay production.
• Rice Stalks and Straw: After rice harvest, the rice stalks and straw need to be cut and managed. Rotary drum mowers can efficiently cut rice stalks and straw, making it easier to handle and manage the residues for various purposes like mulching or composting.
• Wheat and Barley Straw: For wheat and barley crops, the straw left after harvest can be cut using a rotary drum mower. This allows for easier handling, baling, or incorporation into the soil as organic matter.

How Does Tractor 3 Point Hitch Disc Drum Mower Work?

A tractor 3-point hitch PTO driven disc drum mower operates based on the following working principle:

• Attachment to Tractor: The disc drum mower is designed to be attached to the rear of a tractor using the 3-point hitch system. The hitch connects the mower to the tractor's hydraulic lift arms, allowing for easy transport and adjustment of cutting height.
• Power Transmission: The mower is driven by the power generated from the tractor's PTO shaft. The PTO shaft extends from the back of the tractor and connects to the input shaft of the mower. When the tractor's engine is running, it rotates the PTO shaft, transmitting power to the mower.
• Cutting Discs and Blades: The disc drum mower consists of multiple cutting discs mounted horizontally on a rotating drum. These cutting discs are spaced evenly across the length of the drum. Each cutting disc is equipped with two or more cutting blades that are fixed at an angle to the direction of rotation.
• Cutting Mechanism: As the PTO shaft rotates, it transfers power to the input shaft of the mower, which, in turn, drives the rotating drum. The rotation of the drum causes the cutting discs and blades to spin rapidly. When the mower is lowered to the desired cutting height, the rotating blades make contact with the vegetation.
• Cutting Action: The spinning blades create a scissor-like cutting action. As the mower moves forward, the blades slice through the grass or other vegetation, cutting it cleanly. The rotating drum and cutting discs ensure that the entire width of the mower is utilized for cutting, resulting in efficient and swift operation.
• Swath Formation: After cutting, the mower deposits the cut vegetation in a neat and organized manner, forming a swath. The width of the swath is typically equal to the cutting width of the mower. The swath facilitates subsequent operations such as drying, raking, and baling of the harvested crop.
