TOPPA 600 Combi
Harvest Preparation
TOPPA 600 Combi
In order to promote uniform ripening of the tubers, haulm reduction can be carried out two to three weeks before harvesting. In addition to preventing the transmission of viral infections from the haulm into the tuber, a good skin set on the tubers can be achieved to improve storability.
Instead of or as a supplement to chemical siccation, GRIMME offers a sustainable solution of haulm topping. By using a haulm topper, the haulm of the potatoes is mechanically crushed and deposited between the ridges. Careful placement of the haulm between the ridges is important. Epecially if the stems of the potato plants are to be treated with other herbicides afterwards.
A further advantage is the reduced risk of blockage at the intake of the harvester and the resulting increased throughput capacity in case of extreme masses of haulm. Using the (rear mounted) TOPPA 600 Combi, the haulm of twice two rows can be topped in one pass. This type of haulm topper is designed to be combined with another two-row haulm topper in the front of the tractor. This means that, in combination with the TOPPA 200, up to six rows can be topped in one pass. In addition to all common international row- and track widths, it is also possible to fit a flail pattern for potatoes which are cultivated in (separated) beds.
Product Highlights
One-sided machine-lifting
On both the TOPPA 600 Combi and the TOPPA 800 Combi, the two booms can be controlled separately from each other via a hydraulic control box or optionally via ISOBUS with AUX-N assignment. In conjunction with the standard wide-angle PTO shafts, it is thus possible to lift the haulm toppers independently of each other, e.g. on wedge-shaped surfaces.
Pendular compensation
The two housings are pendulum suspended, allowing them to adapt perfectly to uneven ground. A hydraulic side shift is also available as an option.
Automatic ridge self-centre steering
For both TOPPA 600 Combi and TOPPA 800 Combi an hydraulic side shift is available as an option. The feature can be controlled manually or, in the highest configuration level, the machine follows the alignment of the ridges completely automatically. This is particularly relevant if the number of rows of the planter does not match the number of ridges of the haulm topper.
RidgeRunner against green tubers
Optionally, superficial ridge pressing wheels can be selected for each row, which close cracks on the top of the ridges after haulm has been topped. The individual suspension enables optimum adaptation to each row. The extremely low tyre pressure allows the wheels to roll in a targeted manner so that cracks in the ridges are closed. The potatoes can thus be protected from direct sunlight and the risk of green tubers can be reduced. At the same time, fulling ensures that the wheels clean themselves.
Optimum working height
The haulm topper is guided by the tractor's three-point linkage and 175 R14 support wheels. The height of the support wheels is adjusted either mechanically via a spindle or hydraulically from the cab. The set working depth can easily be read off and checked at a scale. In the highest configuration level, automatic height guidance is available with the aid of skids that permanently scan the ridge crowns.
