What are the Features of the BACKHUS Windrow Turners?

We have been developing and producing compost and windrow turners for almost 40 years. The experience we have gained has been continuously invested in the improvement of our machines - today they are characterised by an exceptional variety of practical, safe and economically valuable standards:

  • Eggersmann Track Control 
    Eggersmann Track Control is a load-dependent drive control system with an integrated load limit controller. The machines automatically adjust the forward drive to the resistance on the rotor. 
  • Versatile Rotor Characteristics
    The speed of the rotors is infinitely variable, giving the driver maximum process control during the pass. In addition, the rotors are reversible and can be adjusted in height independently of the frame if required. 
  • Ground Contour Adjustment
    The hydraulic track clearers feature automatic ground contour adjustment. They therefore glide over the ground even if it is uneven, creating a ""floating"" impression. This prevents material from the windrow from getting under the undercarriages, which provides excellent traction. If necessary, the track clearers can be individually adjusted from the cabin.
  • Panorama Cabin
    The 360 degree panorama cabin offers very special comfort. An all-round sunshade, air conditioning, heating as well as a Bluetooth radio and an air-suspended driver's seat make the windrow crossing as pleasant as possible. 
  • On-Board Computer
    A 12 inch touch-screen display ensures highly intuitive operation of the machines. All important information on the status of your BACKHUS is summarised here and presented in an easy-to-understand manner. 
  • Maintenance Platforms
    With their working platforms integrated into the cooling and engine bonnets, our BACKHUS A 45 to A 75 are particularly easy to maintain. When the bonnets are opened, the platforms fold out automatically and allow free access to all components.
  • Hydraulic Rear Flap
    The hydraulic rear flap is an option with many suppliers - with us it is standard. It reduces the heap offset at the beginning of the passage and thus contributes to even better space management. 
  • Sophisticated Cooling System
    The BACKHUS has automatically reversible engine and hydraulic oil coolers, which can also be operated manually. The air intake takes place from the centre of the machine and is additionally protected by removable trapezoidal perforated plates, which makes cleaning easy.
     

How do I Make the Best Possible use of my Space?

We can calculatethe best possible arrangement and size of the individual windrows for you - free of charge, of course. We will also suggest the right BACKHUS compost turner for you.

What Additional Options are Available for BACKHUS Windrow Turners?

Composting, mixing or drying - different applications also require different approaches: We create a customised solution for you from a wide range of additional options and individual adaptations:

  • Irrigation System and Concentrate Spraying System
    We offer the option of an irrigation system to better control the composting process. In this case, the water is supplied via a BACKHUS HD hose drum. The hose drum is connected to the turner by radio and thus automatically controls the unwinding and rewinding of the hose. Alternatively or as a supplement, there is also the option of a concentrate injection unit for even more targeted adjustment of the composting process. 
  • Eggersmann Management System
    This system detects the load on the hydraulic system and automatically adjusts the diesel engine speed to the power requirement. This not only ensures a smooth and constant pass, but also offers great potential for reducing fuel consumption. Savings of up to 10 % are possible with the system. 
  • Side Conveyor
    Our self-propelled BACKHUS already allow an excellent utilisation of space due to the foot-to-foot windrwos. For particularly demanding space management, we also offer the option of a side conveyor. Coupled to the BACKHUS, this shifts the material by one windrow width during the turning, so that a space layout according to the continuous flow principle is possible.
  • Fleece Winder
    A fleece not only reduces the escape of unpleasant odours and the formation of dust, but can also optimise the rotting process, for example, by preventing the windrow from drying out or becoming soaked. With a fleece winder at the front and rear of the BACKHUS, you can wind up the fleece lying on the windrow and unwind a new fleece at the same time. This saves time and the windrow is always well protected.   
  • Camera Package
    With the new concept comprising a total of four cameras, you always have an excellent view of the area behind the machine. There are no more blind spots. This offers you additional safety at work.
  • Mobile Cabin
    The panorama cabin is also available as a mobile version. In this case, it moves down the side of the machine. This considerably reduces the effort required to prepare the machine for transport to new work sites and, on top of that, makes it easier for you to get in and out.
  • XL Track Clearer
    An XL track clearer can be used to increase the maximum windrow width by 0.2 m on the BACKHUS A 38 and by 0.3 m on the BACKHUS A 45 to A 75. This enables optimum utilisation of the available space. 
  • Landfill Version
    In the case of unpaved or very uneven ground, we recommend changing to the landfill version. This includes massive track clearers with a wider undercarriage. The undercarriage thus provides even more traction and lower ground pressure and the track clearer frees the track from debris even under the most adverse conditions.
  • Housing
    The safety and dust protection curtain significantly reduces the emissions that occur during turning - especially dust formation and uncontrolled material ejection are significantly reduced. 

     

Isn't Turning With a Wheel Loader Much Cheaper

Than Buying Another Machine?

We have to answer this question with a clear "no". The turning process takes much longer and the material is not mixed as evenly.
You get a poorer end product at higher operating costs.
Still not convinced?

What Undercarriages are Available for BACKHUS Windrow Turners?

We deliver your BACKHUS from the A 38 with a crawler chassis with exchangeable rubber pads as a standard. Optionally, you have the possibility to choose a wheel chassis (not for the A 38). You can also adapt the crawler tracks to your individual requirements by choosing bar plates, welded steel plates or the landfill tracks.

What Exactly is Composting and How Does it Differ From Biological Drying?

Even if the assumption is close, composting does not necessarily always aim at the creation of "compost" in the sense of a marketable product. Basically, the word "composting" describes the natural transformation of organic material into humus by bacteria in a rotting process. If this "compost" has a high degree of purity, it can ultimately be used as fertiliser. However, materials are often composted for which later use as fertiliser can be ruled out from the outset. Household waste, for example, often contains a high organic content that can hardly be separated from the rest of the waste – yet composting or biological drying is recommended for the following reasons alone:

  • Volume
    Waste with a non-composted organic content has a much higher volume, which makes landfilling more difficult. In addition to processing the material with shredders, etc., regular turning is therefore also one of the efficient methods for decisively reducing the volume.   
  • Energy Expenditure
    Non-recyclable waste such as residual waste is largely treated thermally. The biofractions contained therein consist to a large extent of water, and the high moisture content therefore increases the energy demand during incineration. Biological drying with a membrane or complete composting before thermal treatment is therefore often more cost-effective. 
  • Temperature 
    During composting, temperatures of up to 65 degrees are generated. If municipal waste is not treated before landfilling, uncontrolled composting takes place. The landfill then heats up considerably and hazardous pollutants can escape in combination with the other waste.
  • Gases
    Controlled composting with turners also produces C02, but landfilling untreated material is many times more harmful to the climate. Especially in cavities sealed off from the oxygen supply, methane and nitrous oxide are quickly produced. This can be prevented by regular turning.
