Unique bolt on serrated blades and stopper points which enable ease of service. They are designed to stay sharp and cut through the silage clamp with minimum of effort, leaving a perfect silo face, eliminating secondary fermentation.

The powerful hydraulic cylinders are built to the most stringent industrial standards. The rods are coated with high quality chrome ensuring extensive anti-corrosion protection against chrome flake and rust. This also prevents damage to seals.

15mm side plates using S355 grade steel. The side plates also incorporate a unique stress slide complete with nylon bushes to absorb side on pressure, relieving main hinge pin from bearing all the stress.

The bushed bottom beam provides individual support for each tine, the Blockcutter is fitted with conus two straight tines in the centre and conus three straight end tines. A 12mm wear plate is fitted to protect the beam from being worn over time.



Our Block Cutters feature domed hinge bushes to help prevent damaging the side wall of your silo. The hinge pin has a square head which fits neatly inside the bush.
