Summary of Schulte WR4-P Rock Windrower (Evaluation Report - PDF File - 0.24 MB)

Overall functional performance of the Schulte WR4-P rock rake was good. Ease of operation was very good, while ease of adjustment and servicing was fair.

Typical field speeds were from 3 to 7 km/h (2 to 4.5 mph) while the average work rates varied from 1.0 to 2.5 ha/h (2.5 to 6.3 ac/h). The Schulte WR4-P worked well in rocks ranging in size from 40 to 400 mm (1.6 to 16 in).

Performance was best in fields with average rock size less than 300 mm (12 in).

A tractor with 35 kW (47 hp) maximum power take-off rating had sufficient power reserve to operate the Schulte WR4-P in most field conditions.

The Schulte WR4-P transported well at speeds up to 30 km/h (20 mph). It was safe to operate as long as common sense was used and manufacturer’s safety recommendations were followed. A number of weld failures occurred during the test.

Summary of Degelman LC14 Rock Rake (Evaluation Report - PDF File - 0.28 MB)

Overall functional performance of the Degelman LC14 rock rake was very good. Ease of operation was very good, while ease of adjustment and servicing were good.

Typical field speeds were from 3 to 7 km/h (2 to 4.5 mph) while the average work rates varied from 1.2 to 2.7 ha/h (3 to 6.6 ac/h). The Degeliman LC14 worked well in rocks ranging in size from 40 to 400 mm (1.6 to 16 in).

Performance was best in fields with average rock size less than 300 mm (12 in). A tractor with 35 kW (47 hp) maximum power take-off rating had sufficient power reserve to operate the Degelman LC14 in most field conditions.

The Degelman LC 14 transported well at speeds up to 40 km/h (25 mph). It was safe to operate as long as common sense was used and manufacturer’s safety recommendations were followed. Considerable breakage of rake teeth and tooth attaching bolts occurred in rocks greater than 400 mm (16 in) in size. Tooth breakage was insignificant in smaller rocks.

Summary of Rock-O-Matic 546 Rock Picker (Evaluation Report - PDF File - 0.31 MB)

Overall functional performance of the Rock-O-Matic 546 rock picker was good in small rocks and poor in rocks
larger than 380 mm (15 in). Ease of operation and adjustment were good.
