A1® Series II Single Auger Ring Drive Silo Unloader Features & Benefits

Standard Features & Options


DRIVE RING
This heavy, reversible ring is made from 7-gauge (4.5 mm) thick steel.  The 9′ (2.74 m) diameter ring is flanged to the inside for greater strength and is reversible for greater life. Provides maximum stability for proper machine balance in changing silage conditions.

HIGH PERFORMANCE AUGER
Heavy-duty 10” (254 mm) high-capacity auger is made with 1/4” (6.4 mm) thick flighting. Double flighting at the chipper wheel end, and double kickers at the blower end of the auger provide smooth operation while removing the hardest packed and frozen materials.

RING DRIVE GEARBOX
Power to the drive sprocket is transmitted from a rugged ring drive gearbox that is either shaft driven (one motor drive) or motor driven and totally enclosed (two motor drive). The Patz ring drive torque limiter features a farm proven radial-pin design to provide accurate torque release under adverse conditions of hard-packed and frozen silage while protecting the ring and drive system.

CHIPPER WHEEL
6 self-sharpening steel knives welded securely to chipper wheel to clean silo wall.

WALL WHEELS
Two 10″ (254 mm) diameter heavy-duty polyethylene wall wheels are adjustable for accurate positioning of chipper wheel. An adjustment bolt on each wheel allows for a more precise setting of wheels.

AUTOMATIC LOWERING
An optional electric motor-driven winch automatically lowers the ring-drive silo unloader after it makes each revolution. Adjust the letdown to match the silage condition and desired rate of feed flow.  The automatic lowering control keeps the silage surface level for reliable operation and constant full-flow feeding. This winch control also allows you to easily raise the silo unloader at any time with the push of a button.

SILO UNLOADER SUPPORT SYSTEM

  • Hexapod
  • Tripod

The optional high clearance suspension arms provide extra feed storage and clearance for filling with 16’-24’ models. The hexapod’s 3-cable suspension includes the strongest main cable in the industry at 3/8” diameter!

3-POINT SUSPENSION SYSTEM
3-point suspension system keeps unloader level, eliminating the need for counterweights. Choice of suspension arms to fit tripods or hexapods. Optional high clearance suspension arms available for hexapods (16′-24′ models) to add extra feed storage and lift.

DISTRIBUTOR SUPPORT BOARD
Gravity and power assisted distributors allow for a uniform distribution and better compaction of materials during the silo filling process.
