Steel meets soil once again, but different

New generation plows are available for our changing chemical-free world as some farms return to metal weed control

Glacier FarmMedia – As some farms gradually migrate away from chemical control of plant disease, weeds and insects, farmers have little choice but to revert to some level of cultivation. Steel meets soil, again.

There’s an emerging demand for innovative new generation technology to deal with this challenge. In response, Lemken has introduced its new line of Juwel reversible rollover plows with finishing discs.

A reversible or rollover plow lets the operator change between two sets of mould board shares, so the furrow goes either left or right. This eliminates dead furrows and compaction on the end rows.

According to Lemken, plows leave a clean surface, thus eliminating the hassle of planting through residue. This can create optimal conditions for germination of the next crop. Their studies show that plows contribute to the optimal development of roots by loosening and aerating the main root zone. According to Lemken, clean plow furrows help prevent plant disease and facilitate control of mice and other pests.

The Juwel line of plows is available in a range of sizes and with a variety of technological features. The level of sophistication in the control technology is equal to that found in modern combines and air seeding equipment.

The 8i manages plow rotation and the settings for front furrow, working angle, working width and working depth. It does this through the hydraulic support wheel.

These functions are controlled through the CCI terminal or the ISOBUS system on the tractor. These features are standard equipment.

Additional functions such as furrow press operation or settings for the Hydromatic overload protection are optional.

The Juwel 8i on-board computer allows operating functions to be combined, saved and activated for up to four different scenarios. The user interface on the display makes it easy to adjust any plow setting as required on-the-go. Operator efficiency can be increased by integrating controls compatible with the ISOBUS IL4, such as joysticks.

The GPS-controlled working width adjustment allows plowing with a straight furrow while working toward a target furrow to avoid an additional turn at the headland.

Juwel pairs up with a smooth disc coulter that’s corrugated at the sides to provide continuous drive, even when breaking up large amounts of organic material. The disc coulter arms swivel vertically for depth adjustment. Smooth bearings are double-sealed against dirt. The coulters are available in a range of versions and mounting positions.

The Juwel overload protection system guards against damage from the share point colliding with underground obstacles. The system protects the tractor and the plow. It features a steering system with high trigger and re-entry forces to ensure the system triggers softly and smoothly whenever an obstacle is encountered.

The auto-reset spreader roller is not exposed to high friction forces when the overload system is triggered, or when the plow bodies re-enter the soil. As a result, force loss at the re-entry of the plow bodies into the soil is minimal. This ensures smooth even trigger characteristics and quick plow body re-entry.

When an obstacle is encountered, the elastic surface-hardened spring steel beams and body legs deflect exceptionally far to the side.

The beams are firmly guided to ensure they remain in position.

Juwel features double-cut shear-off protection with a shear bolt standard. The shear bolt additionally protects the plow against damage if the system becomes ensnarled in rocks or roots.

The Juwel T version employs Hydromatic overload protection, which deflects vertically up to 38 centimetres and horizontally up to 20 centimetres at the same time, even when obstacles are hit from the side.

Higher trigger forces can be adjusted from the tractor cabin. A minimum and maximum value for the release force can be set between 120 and 200 bar using an optional tap on the control block. The working pressure is then set hydraulically from the tractor’s seat.
