Lemken Karat 9

Being able to perform stubble cultivation at both shallow and medium depths as well as topsoil seedbed preparation for mulch sowing with a single implement saves investment and operating costs. The Karat is equipped with a quickchange system as standard to deliver this versatility. The entire interchangeable share foot with wing shares can be easily removed using just a linchpin, without tools, and replaced by an interchangeable share foot with narrow shares for deep loosening.

Fitted with wing shares, the Karat is ideal for the first pass of shallow stubble cultivation. A line distance of 28 cm ensures that straw is incorporated intensively across the full surface even at shallow working depths. Moisture loss from the soil is effectively prevented, as all capillary action is disrupted. The share point design is optimised for mixing quality and traction requirements. Both share points and guide plates are attached with a single bolt only.

All mounted versions of the Karat intensive cultivator can be easily and accurately adjusted between working depths of 5 to 30 cm without requiring tools. In the versions with working widths of 3 and 3.5 metres, this adjustment is made via pins and perforated plates which are located at the rear of the implement and can be adjusted from either side. In the rigid 4 metre and folding mounted versions, the working depth can be altered via two adjustment mechanisms located at the front of the implement on either side.

The semi-mounted Karat intensive cultivator is equipped with hydraulic depth adjustment as standard. This allows operators to adjust the working depth continuously via the trailing rollers, all from the comfort of the tractor cabin, during operation. As always, LEMKEN delivers optimal operating quality: there is no need to readjust the concave disc setting after any changes in working depth. Each roller/concave disc unit is equipped with a self-levelling system for precise and constant depth control and smooth operation.

The selection of implement rollers has, among other reasons, depended on the lifting capacity of the tractor and the required wheel load applying on the front axle during transport. As a consequence, it was not possible to fit long mounted implements with a heavy roller for better reconsolidation.
