RAUCH Spreader Settings Guide

Fertilizer spreaders are now commonly used by homeowners with large lawns and commercial agricultural operations. They are used to apply even aerated coats of fertilizers to lawns and large fields. They can also be adapted to spread seeds and other soil additives, making them a multipurpose agricultural tool for farming and gardening. 

One of the foremost manufacturers of agricultural fertilizer spreaders, RAUCH utilizes the spinner discs spreader operating system. Her products offer speed, precision, and operational comfort when applying various kinds of soil amendments. 

They have a wide range of products that are available in both single-disc and double discs models. The single-disc fertilizer spreaders have working widths between 8 to 15m, and under ideal working conditions, the model’s distribution diagram is triangular. 

On the other hand, are made of two counter-rotating discs that result in a semi-elliptical distribution diagram. To obtain distribution uniformity, the working width is generally between 12 and 20m.

Regarding fertilization, there are primarily two basic goals that are sought to be achieved. One is to distribute the correct amount of fertilizer per surface unit area. The other (which is more tasking to achieve and we commonly hear about) is to make uniform distribution over the entire treated surface. 

When the distribution is irregular, it is not difficult to identify it as so, particularly in streaked fields and pastures. Getting a quality fertilizer spreader is great, but that only solves a part of the equation. 

Applying the right settings that would markedly affect the fertilizer distribution across your lawn or field would do great. This is why we have put together this series of charts for various spreading materials compatible with different RAUCH spreader models. 

Before we proceed, however, you should note that due to transportation, storage, and several other factors, your spreading material might exhibit a different spreading behavior even with identical specifications. If you ever need to make adjustments for your spreading material, that can be done by a calibration test.

The RAUCH Fertilizer Chart App 

Peradventure your fertilizer isn’t among the products we listed above, you needn’t worry as we present to you the RAUCH fertilizer chart app. 

Just preceding the 2020 planting season, RAUCH delivered a new, free fertilizer chart app with several new improvements. The app is available to all Android and iOS smartphone users and through it, you can get quick, easy, and safe settings for your RAUCH spreader. 

All you need do is create your profile on the mobile app with your desired fertilizer spreader, its driving speed, and working width. In a well-structured layout, the desired setting data for over 3000 fertilizer granules, organic pellets, slug pellets, and fine seeds are available on the app. 

The app also works great with older versions of RAUCH spreaders. You can follow this link to get more spreader settings from their website or download the mobile app free on your Android Play Store or iOS AppStore. 

RAUCH Spreader Settings: A Step-by-Step Guide

• The RAUCH spreader setting sequence includes a series of preparation, spreading, then cleaning, and maintenance steps. Also, it is crucial to note that users stand the risk of injury during spreading. 
• Contact with the rotating machine components (such as the spreading discs and agitator) can lead to injury. Body parts or objects that come in contact may be caught and pulled in. As such, you should spread only with the safety guard closed and stay clear of the machine while it’s in operation. 

Preparation Stage

Step 1: Hitch the spreader to the tractor. It is important to note that only tractors that meet the technical requirements for the spreader should be used. The tractor must comply with the hydraulic, mechanical, and electrical requirements as found in the RAUCH operators manual. Also, the spreader must be hitched to lie in a horizontal position. 

Step 2: Close the metering slider

Step 3: Fill the hopper with the spreading material. You should never fill the hopper while the tractor engine is running as it may result in serious injuries. Switch off the tractor’s engine, remove the ignition key and never fill to exceed the total permissible weight. 

Step 4: Adjust the drop point

Step 5: Run a calibration test

Step 6: Adjust the filling height and spreading width

Spreading Stage

• Travel to the spreading location
• Engage the PTO drive
• Open the slider and start spreading
• Finish spreading operations and close the slider
• Disengage the PTO drive

Cleaning/Maintenance Stage

• Completely discharge the residues
• Open the metering slider
• Unhitch the spreader from the tractor
• Clean and service
• It is recommended to clean the spreader with a light jet of water immediately after every use to maintain its value. Also, arrange for your dealer to carry out routine lubrication and servicing.
