Distributor (with regular suspension arms)

To achieve an uniform distribution, it is crucial to keep the silage flowing evenly at the silo wall, forming a slightly inverted cone as filling progresses all the way to the top.


Silo unloader - 880SK: Collector ring

Collector Ring

Electrical power is transferred from stationary to rotating part of the machine by extra-large brushes and thick copper alloy rings (CSA approved)

Hybrid Silo Unloader: Chipper wheel

Chipper wheel

The heavy chipper wheel is made of ductile iron to resist shocks. Six self-sharpening hardened steel blades remove silage that clings to the wall.

Hybrid Silo Unloader: High capacity blower

High capacity blower

The 26" high capacity blower with 3 stainless steel adjustable paddle rotating at 1,225 RPM for 8,330 feet per minute tip speed.

Hybrid Silo Unloader: Ring drive Transmission (guards removed)

Ring Drive Transmission (guards removed)

A positive ring and gear drive system provides steady, even cutting under all conditions. Sprocket is driven by a 100:1 worm gear reduction on a shaft from the auger gear box.

Hybrid Silo Unloader: Independent power ring drive (guards removed)

Independent power ring drive (guards removed)

A reliable industrial coupling between motor and the 500:1 gear box assures positive drive. This model require less power during distribution.

Hybrid Silo Unloader: Quality transmission

Quality transmission

A heavy flange coupling between auger and gear box prevents auger from seizing to transmission output shaft. Efficiency: 97 %

Hybrid Silo Unloader: High velocity

High velocity

The blower features 3 stainless steel adjustable impeller paddles that can be set in a swinging or fixed position

Hybrid Silo Unloader: Pressure wheel

Pressure wheel

Cantilevered pressure wheel holds the chipper wheel tight against the silo wall

Silo unloader - 880SK: Powerful auger

Powerful auger

Loaded with sharp cutting knives, the big 10'' auger delivers a steady stream of silage to the impeller for high capacity output

Hybrid Silo Unloader: Quality transmission

Quality transmission

Providing the power to the heavy-duty auger and knives in frozen, hard pached silage requires a heavy-duty gear box. Rated: 20 HP

(Shown with guards)

Three 5/16" galvanized aircraft type cables support the unloader from 3 widely spaced points which result in a lovel cut from top to bottom

The drive ring's large diameter along with wall to wall suspension arms guarantee the perfect equilibrium of the machine without counter weight that has to be adjusted every now and then to match silage conditions. Made of 3/16" thick steel, the 3 ring segments feature a big 9' diameter on the 12' to 20' models. They are reversible giving them twice the durability. Double 48" long splice plates provide rigidity to the whole assembly. On the 24' models, ring segments are beefed-up and make a large 11' diameter ring for a stable and well-balanced machine.

880 SK


The massive 10" heavy-duty auger made of 1/4" thick flighting welded on a 4" O.D. tube for rigidity. It is double flighted at the chipper wheel and to allow the machine to run smoothly in frozen and hard-packed silage. Sharp hardened knives can be installed on auger to chop up to toughest material. Coupled to the gearbox by a 3-bolt flange coupling, the auger assembly is easy to remove.

Hybrid Silo Unloader: Powered Distributor

Powered Distributor

In big diameter silos, the powered distributor throws (with 4 paddles rotor) silage against silo wall to get uniform distribution of silage in the shape of a slightly inverted cone.

Hybrid Silo Unloader: Gravity type distibutor

Gravity type distibutor

In small diameter silos (12' to 16'), the gravity type distributor is normally sufficient to achieve a uniform distribution all the way to the top.

Hybrid Silo Unloader: Heavy duty winch

Heavy duty winch

The Valmetal winch features a heavy cast iran gear reducer. Its 50 to 1 gear ratio makes it easy to raise or lower the unloader.

Hybrid Silo Unloader: Electric two-speed hoist

Electric two-speed hoist

Same heavy-duty hoist with 1/2 HP reversing motor and extra reduction for maximum convenience in unloader control.
