The Method

Removal and filling

The handling and operation of the removal and filling system is practically assessed.
During the removal/cutting of grass and maize silage, the time is measured for every cutting operation and the weight of the removed material. The removal power is calculated in kg/min.
After the removal process, the width and depth is measured from the silage clamp through the removal and filling technology.
After the extraction process, the feed debris (collection losses) not conveyed by the mixing container are collected and weighed. Any edge strip that was left uncut after the extraction operation is measured at the silo wall.
Through the sampling (10 samples) on the silage clamp, the feed structure of output grass silage is examined with a shaker box (screen size 19 mm and 8 mm). During the filling process, 10 samples are taken from the feed stream. In these samples, the feed structure is examined using a shaker box. The size fractions obtained using the shaker box are weighed and the hashing effect of the cutter calculated for the silage.


10 samples of the two mixing components (grass silage, maize silage) are extracted at the silage clamp prior to the mixing and the dry matter content determined through a drying cabinet (24 hours at 105°C). After the mixing (mixing time around 3 minutes) and the discharge, a sampling will be performed on 8 places along the entire discharge path. The first measurement point is after 1 meter, the last 1 meter before the end of the discharge route. 5 samples are extracted at the 8 measurement points. There is at least a one-time repetition attempt with roughly equal mixing proportions. The investigations are carried out with a full and half-full mixes.

The dry matter content of the individual samples at the 8 measuring points are compared with the target value which is calculated from the mass and the dry matter content of the two components of the mixture. The examinations of the mixing accuracy are carried out with the following specification of the feed components: silage (short/long); maize silage (2/3 DM silage and 1/3 DM maize silage). The hashing effect of the mixing auger and the feed treatment are examined with a practical assessment.


The different filling degrees of the mixing hopper are simulated in the laboratory through the loading and unloading of calibrated weights. The weight display of the weighing system and the actual weight are compared with each other, and the accuracy of the weight display is calculated.

Feed discharge

The feed discharge (discharge amount, feed storage, hopper emptying, overview of the discharge openings) is evaluated with a practical assessment.


The handling, operation and the operating instructions of the feed mixer wagon are practically assessed.

Usage behaviour

A practical assessment will be performed to assess whether the engine power is sufficient for all operating conditions. The fuel consumption of the motor is measured using the DLG fuel measurement technique during a complete cycle (cutting of silage and maize silage, mixing and transport drive, discharge).

The maximum speed of the feed mixer wagon is measured with an empty mixing hopper on the DLG measuring track. The turning circle of the feed mixer wagon is measured on the outer front wheel tracks, and with a lowered cutting arm at the outer edge of the cutter. The noise level at the maximum engine speed and different operational states is measured with a closed cabin at the ear of the driver. The noise level is also measured during a drive-by with full throttle.


The maintenance effort on the feed mixer wagon is practically assessed.


The maintenance effort for the feed mixer wagon is practically assessed.

Occupational safety

The occupational safety examination of the feed mixer wagon will be conducted by the German Test and Certification Centre for Agriculture and Forest Engineering (DPLF) – a testing laboratory that is accredited according to the German appliance safety law.

Traffic safety

The relevant documents shall be provided by the manufacturer.


A survey conducted in companies that have the same feed mixer wagon in operations is intended to be conducted to supplement the test results.

The test results in detail

Removal and filling

The results obtained for the removal performance in the silage clamp are very high when loading wagon grass silage, grass and maize silage. The extraction performance shown in table 2 relates exclusively to the cutting operation in the silage clamp. The manoeuvring times required for the tracking of the cutter or the lateral displacement are thereby not taken into account. The measurements have been performed with blades in new condition.

Through the great conveyance channel, the large quantities of feed are easily gathered by the conveyor and transported into the mixing hopper. No blockages were determined during the measurements. On the SILOKING SelfLine 4.0 Compact 1612-13 the loading conveyor channel is recessed into the mixing hopper. Therefore, the hopper capacity can only be utilized to about 85 %. To take advantage of the remaining capacity loading with the cutting arm is recommended not higher than 1 m above the ground.

Proper handling is essential for a clean feed removal from the silage clamp. In order to avoid feed from being ejected onto the covers of the clamp, the cutting drum should be applied below the upper edge of the silage clamp. When cutting the face of the silage clamp extraction depths of approximately 10 cm are possible.

As a result, the wagon must often be moved over for subsequent cuts. The cutter is equipped with 42 curved cutting blades with straight and angled transport blades. These quickly convey the cut feed to the large filling opening and onto the conveyor belt. The conveyor belt quickly transports the large quantities of feed smoothly into the mixing hopper. This prevents the feed from being severely crushed, thus largely keeping the structure intact. The feed crushing by the cutter is comparatively very low (see table 3).

For the loading of maize silage, the feed can be thrown over the hopper when running at full speed and the cutter being in lower position. The speed of the conveyor belt and cutting head can be reduced in maize.

The two-metre-wide cutting drum also enables lossless feed picking on the side walls without large residual strips through a slanted driving approach. The prerequisite for this is a sufficiently wide clamp face. A trained and skilled driver is able to cut the silage on both sides in such a manner, that the remaining strips often break off and fall down on their own. At the same time, loose feed can be pushed all the way to the silage clamp with the ground-touching cutter edge and then very efficiently picked up with the cutter. During a careful operation, the driver is able to perform the feed intake process without any manual work.

With the cutter it is possible to load nearly all feed components. To ensure a clean feed collection, the extraction points should be fixed with a base plate. Round and square bales can be cut if a careful operation is performed. In order to avoid a clogging of the cutting drum, the bale should be carefully cut with a not too great extraction depth. A large dust development cannot be avoided during the collection of fine-particle bulk materials. An external filling from the top into the mixing hopper is therefore recommended.

Small amounts of additive feed components can be easily added through the laterally mounted input funnel (optional). The funnel and the auger should be regularly checked and cleaned.

The SILOKING SelfLine 4.0 Compact 1612-13 was able to achieve a good mixing accuracy with all tested mixing variants. Full and half blends were examined according to the respective capacity. The maximum permissible deviations of ±10  % for forage were met (figs. 5 and 6). The use of the hopper counter knives was omitted during the mixing. The mixing time was limited to three minutes after input of the last component.

The mixing results were determined in the first speed level of the mixing auger. The two speed levels of the mixing auger are beneficial. For small mixtures, feed can remain on the auger. Through a switching on to the faster speed, the feed is thrown down and mixed in.

The hashing effect of the SILOKING SelfLine 4.0 Compact 1612-13 is good. In addition, it can be changed through the positioning of the counter knives and the adjustable blades. In most cases, an additional cutting will not be necessary, because the feed is already crushed by the cutter. When processing very long material it may be advantageous to use the hopper counter knives.

The feed processing is very gentle through the vertical mixing auger. Even with damp and structurally weak components, the feed is mixed gently. A mashing effect is definitely prevented.

Continuous feeding with loosened material and the proper order of the component input provide a beneficial effect for the mixing process. Through this, it is possible to avoid extended mixing times.


The mixing container is connected to the vehicle chassis via three weighing bars. The weight display is performed with an electronic weighing computer. It is mounted in the cabin on the right side above the steering wheel. During the operation, the display is in the driver’s field of vision. The display is illuminated and the 45 mm large digits are easy to read. The accuracy of the weight display depends on the weight of the filling. At a minimum quantity of 130 kg, a deviation of 1.8 % was identified and < 1 % with a maximum payload.

Feed discharge

The feed discharge sometimes occurs in bursts with mixtures containing loader wagon grass silage or hay and straw. However, a relatively uniform feed discharge can be achieved along the entire stretch of the discharge route with some experience and skill. The discharge amount can be easily adjusted through the adjustment of the metering valve, the driving speed and the auger rotational speed. A full hopper can be discharged in about three minutes. The fast stage of mixing auger is highly beneficial for the hopper emptying. Feed residues on the auger and the hoper bottom are thus emptied better. An almost complete hopper emptying can thus be achieved.

For the discharge of large feed quantities (single feed discharge per day), no feed will be run over due to the twin wheels attached in the centre of the rear. The steering in the rear and the associated direct reaction to steering movements require a high degree of practice and skill during the feed discharge.

The left discharge side should be preferred due to the better overview. The right feed discharge can be observed through the right-side mirrors, but requires a considerable degree of routine and skill. The supervision and control on the left side is easier and more comfortable for the driver. In practical use, the discharge quantities were almost always controlled through the engine and travel speed with a fully opened valve.


The driver cab is located in front of the front axle on the left side. All levers and switches are ergonomically mounted in the cabin on the right side. The chassis with the four wheels and the steering by means of twin wheels arranged in the centre of the rear make the vehicle highly manoeuvrable. The rear of the vehicle responds very directly to steering movements, which requires a high degree of skill from the driver during the operation.

This must absolutely be taken into account when driving on public roads and paths. A big advantage is that the front axle is equipped with a disc brake. The pneumatic brakes automatically close when the machine is shut off, and can be actuated with a button on the control panel. Additionally, a foot pedal for the hydraulic operating brake is attached next to the steering column. In practice, the driving speed of the machine is only controlled by the hydrostatic drive. The monitor with the two surveillance cameras for the mixing container and the rear of the vehicle is part of the standard equipment. Especially the surveillance camera at the rear of the vehicle is necessary for reverse driving. However, the outer edges of the mixing hopper are not visible through this. They must be checked using the side-mounted mirrors. A seat-switch automatically switches off the mixing auger if the driver leaves the cabin, thus contributing to the improvement of safety at work.

The operating instructions for the SILOKING SelfLine 4.0 Compact 1612-13 properly describe the work performance with the machine.

The spare parts list is clearly structured and comprehensive.

Usage behaviour

The engine power was sufficient for all operating conditions. For the centralized propulsion, the vehicle is equipped with a water-cooled Volvo 4-cylinder turbo diesel engine, exhaust gas level IV with a performance of 105 kW. The fuel consumption essentially depends on the demanded performance and the conditions, for example, in/on the silo. At full throttle and during load peaks (during the cutting), a maximum consumption of 33 l/h was measured. During a complete cycle (grass cutting and maize silage, mixing and transport drive, discharge of 3,554 kg) an average consumption of 14.8 l/h or 0.9 l/t at a travelled distance of 401 m, see fig. 9, was measured.

With the hydrostatic drive there are two beneficial speed levels. They can easily be set with a push button on the control panel. With a foot-operated hydrostatic valve, the speed can be regulated variably. On our test track and with an empty mixing hopper, a maximum speed of 15.0 km/h in the first level and 27.5 km/h in the second level was measured. The turning circle is comparatively small. The wheelbase is 3.9 meters. With appropriate training and  experience the rear wheel steering can be mastered quite easily. The compact design of the vehicle and the rear wheel steering enable an easy manoeuvrability even at confined extraction points. A turning circle of 7.75 metres was measured on the outer front wheel tracks. With a lowered cutting arm (0.30 m from the ground), 9.62 meters were determined at the outer edge of the cutter. The tyres were perfectly adequate for the conditions during the test.

The noise level was a relatively low 72.3 dB(A) at the maximum engine speed, measured with a closed cabin at the ear of the driver. For other operating conditions, similar low values could be achieved (see table 4).

The values were also low during a drive-by at full throttle with a distance of 7.5 metres from the longitudinal axis of the vehicle. On the right side of the vehicle, a sound pressure level of
77.7 dB(A) was measured on the right vehicle side and 81.4 dB(A) on the left.

For a long-lasting, smooth and trouble-free usage it is recommended to regularly conduct a check of the main components before each use. If necessary, dirt must be removed in order to avoid an impairment of the functionality. Residual feed should especially be removed regularly from the engine behind the driver’s cab.

The inspection and maintenance intervals are prescribed in the operating instructions. Separate maintenance intervals are applicable for the engine. In table 5 the maintenance work which can be performed by the driver is shown.

With loading wagon goods an increased blade wear could be detected on the cutting drum.
The blades should be not be sharpened, but rather turned over once and then be replaced.


In the practical utilization, the SILOKING SelfLine 4.0 Compact 1612-13 was deployed in three DLG farming operations where the vehicle has operated for 80 hours so far. Thereby, 170 mixes were created to date. A mixing wagon of the same type was utilized in 6 farming operations by SILOKING and protocolled accordingly. This vehicle operated a total of 431 operating hours within three months. Thereby, 737 mixes with a total of 2,212.7 metric tons were created. The wear on the cutting blades which was detected during the test period was normal according to the farmers. No malfunctions occurred on the mixing, distribution and discharge systems.

Results of a survey

A survey among owners of feed mixer wagons of the same type could not be conducted because the delivery of the series took place in January 2016.

Occupational safety

The self-propelled feed mixing and distribution wagon SILOKING SelfLine 4.0 Compact 1612-13 was evaluated by the German Testing Centre for Agriculture and Forest Engineering (DPLF). There are no objections to the use of the device for safety-related reasons.

Traffic safety

The tested SILOKING SelfLine 4.0 Compact 1612-13 as a special vehicle is approved for travel on public roads or streets. A registration certificate part I (vehicle registration) is available. The maximum speed of the machine is 25 km/h. To operate the vehicle a driving licence of at least class L is required. Due to the empty weight of 10,720 kg and the permissible total weight of the feed mixer wagon of 12,520 kg, the vehicle may only be loaded with up to 1,800 kg when driving on public roads. For on-premises driving the permissible total weight is 15,000 kg according to the manufacturer.


The criteria tested in the present DLG-Approved Full Test evaluate the functional properties of the self-propelled feed mixing and distribution wagon SILOKING SelfLine 4.0 Compact 1612-13 on the basis of laboratory and practical tests. The tested self-propelled SILOKING SelfLine 4.0 Compact 1612-13 has met the requirements of the test scope regarding the examined criteria.
