Brock’s HARVEST-TIME® Bin Unloading System is Different by Design™: it’s a “two for one” system. This means that you get an under-floor tube and flight conveyor combined with a floor sweep – all economically driven by a single electric motor. With Brock’s HARVEST-TIME Unloading System, you can choose the components that best suit your needs:• The smooth-working HARVEST-TIME Unloader and Power

Sweep combination can be operated from outside the bin, or . . .

• The HARVEST-TIME Unloader can be used with a center pivot to connect to an existing portable sweep.

AN INNOVATIVE UNLOADING AUGER SYSTEM

Heavy-gauge auger flight can be removed and reinstalled even with a full bin.

Hinged belt guard cover for ease of maintenance. The design of the power head facilitates easy motor changeout.

Replaceable auger flight tip in the center well hopper is standard and includes a 10-gauge flight-edge wear strip.

All slide gates are supported by proven, wear-resistant Nylatron® rollers designed to hold their round shape.

Power heads for unloading system include incline or horizontal units.

Easy gearbox access aids inspection and service.

Integral control rod guides are included as standard equipment.

Both the 8- and 10-inch (203- and 254-mm) auger systems fit under Brock’s low height aeration floors in farm grain bins ranging from 15 to 48 feet (4.6 to 14.6 m) in diameter.

NYLATRON is not owned or licensed by CTB and is the sole property of its respective owner.2

HARVEST-TIME® TUBE AUGER UNLOADING SYSTEM

A RUGGED SWEEP WITH A RELIABLE REPUTATION

Power sweep can remain in the bin even when the bin is full of grain – saves the time and avoids the hassle of removing and re-installing the sweep.

A simple shift mechanism is located out-side of the bin to engage the sweep and to eliminate the need to enter the bin for sweep operation.

Sweep drive gearbox has internal shifting mechanism to engage sweep.

Solid rubber sweep drive wheel with 10:1 speed reduction minimizes wear on wheel and bin floor.

One motor on the exterior powers both the sweep and the bin unloading auger through rugged, reliable gearboxes – no extra chains, belts, or wiring required.

Discharge well controls are conveniently located with sweep controls.

Heavy, high-angle sweep backboard construction.

Brock offers an optional EP Kit for the HARVEST-TIME® Bin Sweep. The EP Kit is engineered to increase the performance of the standard HARVEST-TIME Sweep System when working in difficult grain conditions. The kit helps to reinforce the backboard and to intensify the sweep’s aggressiveness in difficult grain.

Brock’s HARVEST-TIME EP Kit enhances sweep usage in:

• Difficult grain conditions or out-of-condition grain.

• Grain that has high compaction as a result of being stored for several seasons.

• Storage bins 24 to 60 feet (7.3 to 18.3 m) in diameter.

The optional kit quickly installs on new HARVEST-TIME Sweep units or easily retrofits to existing HARVEST-TIME Sweeps manufactured after June 2006.

The EP Kit:

• Eliminates floor skid supports and protrusions in front of the sweep auger and allows the auger to more freely engage stored grain.

• Improves the center pivot connection to boost grain flow into center sump.

• Quickly assembles and easily attaches to the sweep’s backboard.

See your Brock dealer or call us for more details on how a Brock HARVEST-TIME Unloading System can help you better manage your stored grain.

ENHANCES HARVEST-TIME® SWEEP PERFORMANCE

The HARVEST-TIME® EP Kit consists of a rectangular torsion tube that attaches to the back board of the Sweep.

Combining the HARVEST-TIME® Unloading System with Brock’s optional WELL-GARD® Discharge Guard (patent pending) is the best method for avoiding or dealing with plugging of the center sump. Attached to the sweep, the WELL-GARD unit simply rotates with it, so removal is not necessary during sweep operation.

• Helps maintain continuous flow of grain out of the bin.

• Limits bridging and blocking caused by chunks of grain.

• Long-lasting, heavy-duty galvanized steel construction.

OFFERS 40% MORE UNLOADING CAPACITY THAN 10-INCH AUGER TUBE SYSTEMSBrock’s HARVEST-TIME® 10-Inch (254-mm) U-Trough Auger and Power Sweep Unloading System with a capacity of up to 7,800 bushels (198 metric tons) of corn per hour offers you up to 40% more grain moving capacity than 10-inch (254-mm) diameter tube systems. It’s a heavy-duty system you can grow with, plus get the same great advantages offered by Brock’s HARVEST-TIME Tube Auger Unloading System:

• Smooth-working unloader and sweep combination that can be operated from outside the bin, or ...

• An unloader that can be used with a center pivot to connect to an existing portable sweep.

Rack and pinion controls for sweep and discharge wells are conveniently located together outside of the bin

Optional HARVEST-TIME® Power Sweep can be added at a later time if desired

U-trough system conveniently fits under Brock’s TRI-CORR® Floor and low PARTHENON® Floor Supports
