View of the Rasspe RS 312D binding machine

Introduction

In tree nurseries, bundling plants, shrubs, and cuttings is a recurring operation that requires time and precision. The Rasspe RS 312D tying machine has been specially developed to speed up and standardize this process. Thanks to its robust construction, powerful knotting mechanism, and the use of twine instead of elastic, this machine has become a trusted standard within the sector.

In this article, we take a closer look at the technology behind the RS 312D, its practical advantages in the field, and tips from the manual and instruction videos.

Application in the tree nursery

The Rasspe RS 312D is widely used for:

• Rose plants
• Ornamental shrubs
• Young trees and woody crops

Because of the firm tying with twine, bundles stay tightly together, even during transport or storage. Unlike elastic binders, bundles cannot shift or come loose — ideal for heavier or stiffer products. "The Rasspe RS 312D ensures a consistent, strong binding without damaging the plant material."

Technology: the heart of the machine

The Rasspe single knotter

The core of the RS 312D is the proven single-knot knotter head, a mechanism originating from agricultural balers. This knotter ties a real knot in the twine — not a loop or wrap — resulting in:

• High tying strength
• Accurate knot placement
• Long service life without slippage

The reliability of this technique is one of the main reasons why Rasspe tying machines have been the standard in tree nurseries for many years.

Drive and construction

The RS 312D is equipped with:

• Low-noise V-belt drive → fewer vibrations, more comfortable operation.
• Solid rubber rollers → stable feeding of bundles, even with varying product diameters.
• 3-point hitch → easy to mount on the tractor, ideal for field work.
• Compact design → suitable for both indoor use (in warehouse or processing area) and outdoor field use.

Thanks to this combination of simplicity and robustness, the machine is low-maintenance and resistant to intensive use.

Suitable for synthetic tying twines

The machine is designed for synthetic twines with a running length of 600–900 meters per kilogram. These twines offer:

• Consistent thickness and tensile strength
• Less stretch (resulting in tighter bundles)
• Weather resistance for outdoor use

Using twine instead of elastic also has the advantage that the binding remains durable and stable, even after long-term storage.

Operation and control

Operating the RS 312D is simple and efficient:

1. The operator places the product into the machine.
2. The machine automatically feeds the twine through the knotting mechanism.
3. The knotter head ties a knot with adjustable tightness.
4. The bundle exits at the discharge side.

The tension of the binding can be adjusted depending on the product type:

• Tighter for woody crops (such as roses and shrubs).
• Looser for softer materials.

Use indoors and outdoors

The RS 312D is suitable for various working environments:

• In the warehouse: stationary use at sorting or packaging lines.
• In the field: mobile, using the 3-point tractor hitch.

This flexibility makes the machine ideal for growers who both harvest in the field and process indoors.

Maintenance and lifespan

One of the strengths of the RS 312D is its low maintenance demand. Regular maintenance significantly extends its lifespan:

Main maintenance points:

• Clean the knotter head after use to prevent dirt buildup.
• Check V-belt tension periodically.
• Lubricate moving parts according to the manual.
• Use high-quality twine with consistent thickness.

The machine is designed so that all critical parts are mechanically accessible, making service and maintenance easier.

Comparison with other tying systems

The RS 312D therefore offers a unique balance: strong, reliable, and gentle on the product.

Practical tips from experienced users

• Regularly check the twine path in the knotter head — dirt or fraying can affect knot quality.
• Store twine in a dry place to maintain consistent knot performance.
• Use a collection table or conveyor to discharge bundles directly.
• Do not let the machine run idle unnecessarily to reduce V-belt wear.

"The Rasspe RS 312D is not a high-tech machine with sensors, but a mechanical masterpiece: precise, reliable, and built to last for decades."

Conclusion

The Rasspe RS 312D tying machine is a proven solution for growers seeking:

• Fast, consistent tying,
• A strong knot without product damage,
• And a durable, low-maintenance construction.

With its simple mechanics and proven Rasspe knotting technology, the RS 312D combines strength with reliability — exactly what is needed in the daily practice of tree nurseries.
