Windsor create a range of agricultural machinery parts including Combine Harvester Raspbars. These are an important part of the threshing system on the combine harvester. When choosing a raspbar ensure its compatible with your machine, size, tooth design, material and mounting. This will help you as an Agricultural Machinery dealer, distributor, importer or owner to select the correct product.
What Is a Raspbar?
A raspbar is part of the threshing system inside compatible combine harvesters. They will be designed, shaped and positioned according to specifications made by the equipment manufacturer.
Depending on the model of the combine harvester and threshing system, the Combine Harvester Raspbar can vary in length, teeth design, thickness and mounting. Ensure you know what type you need before ordering.
Why are they Important?
Threshing is a key function of the combine harvester. It processes the harvested crop by passing it through the threshing system to separate the grain.
A well maintained raspbar is important. The raspbar has a specific shape and will need to be compatible with your harvesting equipment.
If the raspbar is worn, damaged or incorrectly fitted it can affect how the machine works. To ensure your machinery is well maintained regularly check and replace with the correct product.
Different Types & Designs
There are a range of raspbars available, we have listed some below:
1. Standard Raspbar
This will be produced to meet specific requirements. Ensure you know what size, teeth and mounting it needs.
2. Flat Raspbar
This is used on a specific threshing system. Ensure it is the correct size and mounting.
3. Thin Raspbar
Some harvesting systems will be using a specific thin raspbar. Ensure you check what specification the original had.
4. Hard Chrome Raspbar
Hard chrome versions are available. Enquire what finish and specification is needed.
5. Heat Treated Raspbar
A heat treated product is produced using a specific process. Depending on the design, material and application it can be suitable.
How to Choose the Right Raspbar
When choosing a Combine Harvester Raspbar, ensure you know the following:
1. Know what model of machine you have. Find out who produced the combine harvester, model and type of threshing system.
2. Size. Ensure the length, width, thickness and hole positions match.
3. Teeth design. Depending on the design there could be a different pattern of teeth. Ensure you know what design you need.
4. Material. Ask for the correct material and specification.
5. Part Number. If you know what part number the original was this can help you find the correct replacement. If you don’t then provide us with the measurements and pictures.
6. Special Requirements. If your machine requires a specific design then provide us with the technical drawing or original sample.
Materials & Manufacture
The material and manufacture of the raspbar will affect whether it is suitable for your application. Ensure you know what material it is made from, size and material specification.
The Combine Harvester Raspbar should be manufactured to meet the requirements of the relevant equipment. Ensure it is the correct size, teeth, hole positions, finish and heat treatment.
By ensuring the product has been quality checked during manufacture you can ensure there are no issues with the size or build. When ordering a replacement part ensure you ask for the correct technical information for your machine.
Tips For Maintenance
It is important to regularly check your harvesting equipment as the parts will be under constant pressure and stress.
Some tips are:
Look for cracks, warping and excessive wear.
Check the mounting points and fixings according to the equipment manual.
Check for uneven wear.
Remove any build up of crop as required.
Replace damaged parts according to the manufacturers recommendations.
Ensure they are the correct specification.
Always ensure you check and maintain the Combine Harvester Raspbar according to the safety and maintenance guidelines provided by the machine manufacturer. Ensure the machine is switched off and the key removed before doing so.
Common Mistakes
A common mistake is to choose a raspbar based on appearance. Just because two products look the same doesn’t mean they are the same size, teeth design or mounting.
Another mistake is not ensuring they are compatible with your machine. They may not fit due to being designed for a different threshing system. Don’t assume they will all be the same material or finish.
When ordering a Combine Harvester Raspbar ensure you provide the supplier with the machine model, original part number, required size and pictures. This will help to avoid any confusion.
Why Specifications Are Important (International Buyers)
As an agricultural machinery business you may have a range of combine harvesters from different manufacturers. This can mean you will need different replacement parts.
Ensure you have the correct information when ordering threshing parts. Providing the correct product code, size, quantity, packaging and compatibility will help to make the ordering process easier.
When ordering a Combine Harvester Raspbar ensure you know all the specifications.
Conclusion
Raspbars are an important part of the threshing system on a combine harvester. Ensure they are the correct design, size, teeth and material for your machine. By choosing the correct product, regularly checking and fitting correctly your harvesting equipment will be well maintained.
