Soil is agriculture’s most valuable asset. Nurtured and managed well it is key to healthy crop establishment and good yields. One of the biggest challenges faced by many arable farmers today is compaction of the soil structure. Great Plains offers a range of soil looseners that can eliminate the compaction layers created by the plough, disc harrow or cultivator, which can adversely affect yields and form a barrier to essential moisture. As well as maintaining a uniform soil structure, sub-soiling helps to keep soil organisms, such as worms, alive and reduces surface compaction from tractors and combines. The Great Plains range offers a variety of tine systems and configurations, for shallow or deeper working and for operations where minimal surface disturbance is required.
Available with hydraulic auto-reset tine or shearbolt options and a choice of six rear rollers, the Great Plains Simba DTX® is extremely versatile. Designed as a mounted one pass stubble incorporator/soil loosener for tractors in the 200-360hp range, it can be used as a first entry machine into non- inversion tillage or to knock down ploughing, whilst loosening down to 400mm. It is also ideally suited to establishing oilseed rape straight into stubble, as it leaves a very level, fine and consolidated seedbed.
The benefits of selective soil loosening should never be underestimated, particularly following a wet autumn. Healthy root growth is essential if crop yields are to remain high. Any subsurface pans must be identified and then removed.
Incorporating the latest technology, the Flatliner offers the perfect solution.
A choice of two ranges provides maximum shatter of deeply embedded compaction layers with minimum surface disturbance across the working width. The Pro-Lift leg and point provide a very effective soil conditioning action with prolonged wear rates.
The Simba ST Bar with between 4 and 7 ST tines can be fitted ahead of Mounted X-Press models with working widths of between 2.5 and 4 metres. This transforms the machine into a one pass cultivator for tractors between 145hp and 220hp. ST tine options include Shearbolt protection and Bolt-On units. In addition, LD (Low Disturbance) tines are also available.
The Great Plains Simba TL is a linkage-mounted cultivator designed primarily for use on lighter soils, and in rotations including root crops and vegetables. It features three rows of spring-reset cultivating tines that can work deep enough to incorporate large volumes of trash, such as potato haulm or the remains of field vegetables, or perform a thorough soil loosening action ahead of further cultivation.
The Great Plains Inline Sub-Soiler is another step in the evolution of our vertical tillage family designed to eliminate yield-robbing compaction layers created by horizontal tillage tools such as plows, disks, and sweep implements.
