Shear grabs

Shear grab SILO CAT

Professional silage extraction technology assures feed quality

From mowing to the loading of feed into bunker silo – many important factors need to be taken into account to achieve optimum feed quality. However, it is not only the silage making process that is essential for high-quality feed – the ongoing extraction of silage also has an influence on the daily quality of feed. The aim here is to use an appropriate technique to keep the cut surface clean and accurate, preventing the ingress of air and the development of yeast and fungal mould. With the SILO CAT shear grab from MAMMUT, you can be assured of a precise cut during extraction from the silo, and the silo contents remain firm and unimpaired. These shear grab is perfectly suited to grass silage. From Type H, they also enable round bales to be divided up effortlessly.

Avoid reheating

Above all at high temperatures or with smaller extraction quantities, there is often the danger of air ingress in the silo tower. With SILO CAT shear grab, the cut surface remains smooth and the silage maintains its anaerobic stability.

Protective technology

The less effort required to cut out the feed, the less impact the extraction process has on the silo tower and carrier vehicle. With its unique design, the MAMMUT shear grab defines new standards in relation to ease of operation.

Also suitable for round bales

From Type H (opening height: 1.10 m), the shear grab can also split up round bales. This saves time and makes the livestock feeding operation easier because there is no need to swap over the tool attachments.

Basic feed quality is the key to reliable performance combined with optimum livestock well-being

To produce high-quality basic feed, all of the steps in the feed production process are important. When loading into the mobile silo, uniform spreading and precise compaction are important. Livestock only enjoys eating tasty feed of an appropriate level of quality so it is advisable to avoid accidental fermentation. Having the correct extraction technology is of decisive importance to maintaining silage quality after opening up the silo. Here, the use of the wrong technology often causes the accidental ingress of air which causes the formation of yeast & fungal moulds. This causes the silage to reheat which in turn causes losses in the quantity of feed. Through smooth and accurate cutting at the silo, oxygen cannot enter and this prevents accidental fermentation.

Costs at a glance

Usually, an attempt is made to compensate for feed losses caused by refermentation by adding larger quantities of feed – but in the long-term, this constitutes a huge cost factor for a farm, and also affects the ration measured out for each animal. The design of SILO CAT shear grabs constitutes an economical and efficient solution in silage extraction technology – preventing feed losses while also maintaining feed quality and related performance levels.

The ingress of air into a loosened up surface in the silo tower can also make it easy for aerobic organisms such as mould fungi or bacteria to propagate.

With the SILO CAT, it is easy to achieve an accurate, smooth cut in the silo which prevents accidental fermentation and feed losses.

Feed is protected by a carefully thought out design

The silage shears from MAMMUT deliver convincing ease of operation and a clean cut – this technology reduces the power consumed by the carrier vehicle and on the silo tower, the ingress of air is prevented by the perfect edge on each cut. Key aspects of this are the cutting radius that approximates the ‘neutral phase’ in the SILO CAT. In addition, the double-walled design equips the device with great structural strength – all of the reinforcements are located inside the cutting basket. This ingenious design makes it easy to cut right through without much resistance and the silo block can be removed from the feed tower easily, not requiring much force to be applied.

Welded Hardox knife cutter for optimum cutting characteristics.

The welded knife cutter made of Hardox steel delivers many benefits: An important aspect of efficient cutting characteristics is the geometry of the blade – on the SILO CAT, the pointed and sharp tines make it easy to punch through the feed. Also, the flat welded seams provide a smooth transition between cutting basket and cutter, facilitating convenient cutting action in the silo with a low level of resistance. To complement the ingenious bucket design of the silage shears, the carrier vehicle therefore only requires a low operating pressure to cut through and separate the block. The Hardox steel used for the cutting surface can cope with any level of strain and guarantees ultimate quality for many years.

Quality from Austria

High impact power and progressively larger carrier vehicles are a response to the increasing demands on silo extraction technology. Especially when feeding livestock on a daily basis, it is important to avoid the need for frequent repairs. The SILO CAT silage shear grabs were developed for the very highest of load ratings – and their ingenious design lives up to what it promises: generously proportioned bolt diameter (types N, M: 50 mm Ø / types H, XL: 60 mm Ø), as well as a wear-resistant plastic plate on the main mounting guarantee a long service life for the machine.

Torsionally resistant even when extracting large quantities

The double-walled design of MAMMUT silage shears not only maintains a low cutting pressure, it also provides a total absence of distortion so the machine does not need to have a flow divider valve. In addition, a torsion rod in the cutting basket provides stability to the shear grabs (e.g. when cutting out half of a silo block). The powder-coated frame and the welded knife cutter made of Hardox steel help the silage cutting bucket to retain its value for many years.

Robust silo block for supply storage or for the feed kitchen

The modular design of the innovative silage shears from Mammut, which locates all reinforcements inside the cutting basket, creates an absolutely smooth surface on the machine. This protects the silo block from accidental ventilation, keeping it compact and stable. The properties of the silo block play a big role, especially with automatic feeding systems. The best way to load the supply boxes is to equip the SILO CAT with a hydraulic pusher.

Rapid adjustment to suit different carrier vehicles

Bolted attachment plates and central mounting points for accessories all combine to provide the SILO CAT shear grabs with ultimate levels of flexibility. Here, MAMMUT provides a wide choice of varied attachments for the back of the tractor (with and without lifting gear) as well as for front loaders, wheel loaders, farmyard loaders or telehandlers. When using the silo shears with grass and maize silage, a wide range of accessories helps to make operation more convenient. All attachments and accessory variants can be screwed into place.
