Stubble removing machines are used in agriculture to manage crop residue after harvesting, often by chopping the stubble and collecting it for other uses like manure, bedding, or biomass. These machines, such as the tractor-mounted systems, cut stubble close to the ground, collect it, and can even be integrated with harvesters to eliminate the need for burning and reduce labor and costs, as described in this article from IIT Ropar TIF (AWaDH).

This video demonstrates how a stubble removing machine works and its benefits:
Types of stubble removing machines
- Tractor-mounted stubble collectors: These machines are designed to be pulled by a tractor, chop stubble to a few centimeters above the ground, and often load it into a cart or trolley attached to the machine.
- Integrated machines: Some machines are being developed to be mounted directly on combine harvesters to cut stubble and collect it in one pass, which further reduces diesel consumption.
- Sugarcane stubble shavers: These are specialized machines for sugarcane, which are used to shave the stubble from the ground and prepare the field for the next crop.
- Baler machines: These machines are designed for off-site management, where they compress and bind the stubble into bales for easier transport and storage.
- Super seeders: These machines are used for in-situ management, where they sow seeds while simultaneously chopping and mulching the stubble into the field. [1, 2, 3, 4, 5]
This video explains how a stubble removing machine works and its applications:
Benefits of using stubble removing machines
- Cost-effective: By reducing the need for labor and fuel, stubble removal machines can save farmers money.
- Labor-saving: Many machines can be operated by a single person, significantly reducing the labor-intensive task of stubble removal.
- Environmentally friendly: Stubble removal machines provide an alternative to stubble burning, which pollutes the air and contributes to global warming.
- Resource-efficient: Stubble collected from the field can be used for other purposes, such as creating manure, fuel, or bedding material for livestock. [1, 2, 6, 7]
This video explains the role of stubble management in reducing pollution:
How they work
- Chopping and collecting: The machine uses a chopping mechanism to cut the stubble into small pieces.
- Conveying and loading: A conveyor system then transports the chopped stubble to a cart or trolley for easy disposal or collection.
- Sowing seeds: Some machines, like the super seeder, are designed to sow seeds directly into the soil, while also incorporating the stubble back into the soil. [1, 2, 5]
