New AMAZONE KE 02 Rotamix rotary harrows for seed drill combinations

AMAZONE has extended its new KE 02 Rotamix rotary harrow range with two new models.

The new models, the KE 02-150 in working widths of 2.5 m and 3 m for tractors up to 150 hp, and the KE 02-190 in working widths of 3 m, 3.5 m and 4 m for tractors up to 190 hp demonstrate their strengths, particularly with their intensive soil crumbling. The range is topped off with the KE 02-240 for the more powerful horsepower classes up to 240 hp.

The Rotamix system – close-coupled, compact and two extra tool carriers at 3 m 

The KE 02 rotary harrow, with the Rotamix system, has four tine carriers per metre of working width. The incoming power is evenly distributed across these rotors. The trailing tines produce a very good crumb structure, even on heavy soils. The new rotary harrows are therefore very well suited for seedbed preparation, particularly following the plough.

The number of tine carriers enables the use of a smaller spur gear diameter. This means that the sturdy gear trough can be designed to be very compact and therefore lightweight. The short design ensures that an attached seed drill can be positioned very close to the tractor. This reduces the leverage on the tractor and so the lifting power requirement is also less than with other rotary harrows. 

The tried and tested Quick+ Safe system provides the 290 mm tines with an integrated stone release plus the tines can be easily exchanged without the need for tools.

A higher class of performance with the DirectDrive gearbox

The Long-Life-Drive system, including the DirectDrive gearbox, ensures a long service life and maximum smooth running. The double sealing system with cassette seal and labyrinth seal protects against dust, moisture and dirt ingress. 

The heart of the new rotary harrows is the DirectDrive gearbox, via which the higher power flow is transmitted directly to the spur gears of the tine carriers. On the new KE 02 Rotamix there is no power redirection thus ensuring an excellent, low-wear, power transmission. The new rotary harrows can be used with PTO speeds of 540, 750 or 1,000 rpm. Exchange gear sets allow the tine carrier speed to be adapted to different soil conditions and to the PTO speed of the tractor.

Thanks to the new drive train with the high-efficiency DirectDrive gearbox, the KE 2502-150 and KE 3002-150 are approved for tractor outputs up to 150 hp. By using the drive train with more hardened and tempered components, the KE 3002-190, KE 3502-190 and KE 4002-190 are approved for use up to a tractor output of 190 hp. The KE 3002-240 and KE 4002-240 rotary harrows are even approved for up to 240 hp thanks to their even stronger DirectDrive gearboxes. 

Setting and tools

Using the optional hydraulic depth control, the rotary harrows can easily be adapted to the actual conditions in the field from the tractor cab on the move. A scale assists in constant monitoring of the working depth. As an alternative, the working depth can be set using an eccentric pin in a series of holes. 
The KE 02-150 and 190 models have a rigid, Cat. 3N lower link cross shaft.

The levelling board for levelling the soil is guided precisely at the correct height by the packer roller and is able to be deflected upwards using the integrated overload safety protection. A universal setting tool is supplied for fine-tuning the settings, which can be used for many tasks, such as setting the height adjustment of the side plates or for setting the track markers.

Versatile roller range 

Numerous roller types with different diameters for targeted reconsolidation are available for a wide range of site-specific requirements. The cage roller, as lightweight entry-level packer for controlling the depth of the rotary harrow, gives full-area but only slight reconsolidation, whereas AMAZONE offers the tooth packer roller for full-area crumbling and reconsolidation. The wedge ring roller, for light to medium soil types, reconsolidates in strips in the seed row. Optionally also with Matrix profile for an even better drive in lighter soil types. The roller programme is rounded off with the trapezium roller, also giving strip-wise reconsolidation in the seed row.
