Summary of Brandt 852 Super-Charged Grain Auger (Evaluation Report - PDF File - 0.67 MB)

Rate of Work: At the 30 elevation angle, corresponding to a discharge height of 26.5 ft (8.1 m) maximum capacities were 3590, 3580, 3775, 3040 bu/hr (103, 68, 99, 66 t/h) in wheat, oats, canola, and standard material respectively. Maximum capacities were usually obtained at flighting speeds between 440 and 600 rpm.

Quality of Work: Quality of work was good. In dry wheat. damage was less than 0.2% for each pass through the auger.

Ease of Operation and Adjustment: The discharge height could be varied from 12.3 to 33.3 ft (3.8 to 10.1 m). Bin eave clearance varied from 8.1 to 17.3 ft (2.5 to 5.3 m) and reach varied from 15.3 to 24.0 (4.7 to 7.3 m) at elevation angles of 130 to 41°, respectively.

Ease of operation was good. The Brandt 852 was easy to maneuver and position due to the relatively light hitch weight of 57 lb (26 kg). Adjustments for discharge height were accomplished by rotating the cable winch handle.

Ease of hitching was very good. The removable tow hitch was easily installed for towing and easily removed for operation of the auger.

Ease of transporting was very good. It was stable at speeds up to 20 mph (35 km/h) on paved highways.

Ease of lubrication was very good. Only the power shaft had grease pressure nipples.

Power Requirements: Power requirements for the Brandt 852 auger ranged from 5.5 to 18.8 hp (4.1 to 14.1 kW) in dry grain.

Operator Safety: Operator safety was good if normal precautions for safety were observed. The auger complied with all current standards for safety.

Operator's Manual: The operator's manual was very good. It was well written, organized and illustrated.

Mechanical History: One minor problem occurred during the testing period.
