Cresco Sliders and Slider assembly

Different Spreading Applications – What is that?

The Cresco 10, 20 and 30 spreaders are supplied with two interchangeable slider plates. This world first Cresco development facilitates accurate and easier spreading of different types of material.

There are two main uses for pedestrian spreaders: salt spreading and fertilizer spreading. As a supplier or a user of spreaders, stocking or using more than one type of spreader is an unnecessary extra cost.

When there is a requirement to spread a high-rate (high volume) application of a material with poor flow characteristics, a large outlet hole in the hopper is preferable and will perform better. For example, a coarse salt application in winter is best applied using the large single hole slider.

Where a specific, accurate low or medium volume is needed for fertiliser, ice melt or seed application, a precise 3 outlet hole slider provides the required accuracy.   

Only Cresco spreaders come with this innovation at no extra cost. The two sliders are in the box!

How to choose the right Slider

The 3 hole (summer) slider plate is the more complex; it provides ultimate accuracy and is to be used with free flowing materials such as fertilizer or grass seed.

The Summer slider has Left and right adjuster sliders which provide the ability to balance the spread pattern on the left or right side. These two adjustable sliders manually move forwards and backwards to increase or decrease the size of the left and right drop holes.

This feature overcomes the issue of heavy large materials spreading more to one side than the other and likewise the reverse with fine and lightweight materials becoming dominant on the opposite side of the spread pattern.

Creating an even spread of material is very important when applying fertiliser. Too much to one side and you’ll have uneven grass growth, too little to one side and your grass will look thin and weak.

Unfortunately, creating an even spread is difficult. Every fertiliser comes in a different shape and size which creates a different mass. The mass of the granule effects how far it is thrown and to which side of the spreader.

As a result, a granule with a small mass will be thrown more to the left (on Cresco spreaders) and a granule with a larger mass will be thrown more to the right.

By having adjustable settings to open and close the output holes, you will no longer be stuck with an uneven spread pattern and ultimately a poor looking lawn.

How to Use the Left and Right Sliders

To achieve an even spread with a large, heavy material, you will need to adjust the left slider by closing it in increments. This will close down the left application hole meaning less material will drop on to the back of the impellor. Heavy material that hits the back of the impellor will fly off quickly to the right side as the impellor is turning anti-clockwise.

Image shows the application holes with the left slider adjusted. This shuts down the application holes on the left side and lessens the amount of material falling on the back of the impellor.

For a light material such as grass seed or a fine powdery material, engaging the right adjuster slider by stages will incrementally reduce the density of material on the left side of the spread pattern. This balance the spread to achieve improved uniformity of application on the left and right side of the spread pattern.  

With a typical mini granular fertiliser the spreader is designed to spread uniformly without engaging the Summer left or right Sliders.

Although it is not essential to engage the Summer sliders when spreading materials, by using them in the correct manner the results achieved by the applied product will be improved as the uniformity of application is maximised.

What is Border Control and do I use it?

The Border Control is the second feature of the Summer sider. By engaging the Border Control Slider the centre and right side drop holes are cut off completely which significantly adjusts the spread pattern.

Closing the centre and right hole will stop the spreader from broadcasting fertiliser to the left-hand side. However the spreader will continue to spread fertiliser on to the right side normally.

By engaging the Border Control, areas such as patio’s and flower borders can be protected which will prevent weeds from growing.

Note the Border control will not be effective when the left side Slider adjuster is engaged. In this situation when the Border control is required, disengage the left side Slider adjuster, and reengage it to the same position when the border control work is completed.

The Winter Slider – Why you need a large application hole for spreading salt

The single hole (Winter) slider provides a large single drop hole. It is predominantly designed to improve the spread of large particle size materials that are generally difficult to spread due to poor flow characteristics. All types of salt application are best applied using the Winter slider. As well as products that require a large volume of output like a sharp sand or flowable top dressing application to turf areas.

An exclusive second feature of the Cresco Winter slider is the reduced application feature. By engaging the secondary Slider plate, the spread width is reduced on both sides to approximately half 2 metres. This exclusive feature reduces salt wastage when spreading in confined areas or on pavements and sidewalks.

WARNING

It must not be used for spreading fertiliser or any other products that require precise measured uniform application. Products such as granular herbicides, specialist ice melts and any granulated chemical products must be applied using the Summer Slider system.

 

Slider assembly

Inserting or Changing from one Slider to the other is a simple and quick task. To insert a Slider simply invert the spreader so the bottom of the hopper is easily accessed.

From the back of the inverted spreader, slide the Slider plate rails in a forward direction between the protruding 4 screws and washers at the bottom of the hopper.

Place the lower linkage through the pivot bracket.

Take the other end of lower linkage and push it through the hole at the back of the slide plate.

Secure with the R-pin.

Checking the Calibration Setting

When completed check the calibration setting is correct on the handle gauge assembly. When the holes of the Slider are fully open the gauge must be in the 20 position. When the holes are fully shut the gauge assembly should be in the 0 position.

To make an adjustment simply loosen the screw that secures the control rod to the gauge assembly. Position the Slider plate in the fully open position and set the lever at the 20 positions on the gauge. Tighten the screw tight.

Below is an idea I have that could be in the manual or a sticker on the spreader
