2021 Grimme GF Series 400

The rotary tiller type GF 400 is suitable as a full width tiller for an optimum seedbed preparation for the cultivation of various vegetables and potatoes. An ideal prepared seedbed is the prerequisite for optimum development of the seed resp. planting tubers. Through intensive soil cultivation, root crop ground preparation is perfectly achieved so that undisturbed growth of the crop can be guaranteed. For conventional hilling (in a second working step) the rotary tiller GF 400 can be modified to be used as a rotary hiller. The machine can be converted from independent rows to a full width tiller with a few simple steps. For the best protection against soil erosion, the tiller can be equipped with the dyking system, called TerraProtect. The rotary tiller GF 400 can also be used in combination with a potato planter, thus enabling soil cultivation and planting in a single pass. For soil cultivation and seeding of fine seeds in a single pass, the rotary tiller GF 400 can be equipped with hydraulically driven ridge pressure rollers and a lifting frame for seeders.

The shaping board XL creates ridges with a large volume, so that there is enough space for a large tuber-nest.

An increased rotor speed and a high number of tines (option) ensure an intensive tillage on heavy and sticky soils.

Especially for cultivation of chicory and carrots, the ridge crowns are smoothed by the hydraulically driven ridge pressure rollers. For the shaping board as well as for the ridge pressure rollers different versions for different row widths are available.

Most powerful rotary tiller in the market, using a heavy duty gear box for tractors of up to 500 HP.

TerraProtect creates small transverse ridges, so-called dykes, between the ridges. The dykes reduce the risk of erosion and at the same time promote water absorption.

Features may include:

• Conventional ridge hilling

• Full width tiller combined with a potato planter for a more efficient use of the working time and reduced drivings over the field with up to five working steps at once

• An increased rotor speed and higher number of tines ensure an intensive tillage on heavy and sticky soils

• Up to five loosening tines can be used for deep cultivation, to achieve perfect bed preparation and better water absorption.

• Protection against erosion in all agricultural crops grown on/in ridges: The partnership of a loosening tine and the dyker, both working between the ridges, TerraProtect ensures a more efficient water absorption in the ridges and also provides maximum protection against soil erosion.

• Full width tilling for an optimum seedbed preparation for potatoes or other vegetables

• Lifting frame for seeder (e.g. carrots, celery etc.) soil preparation and seeding in one working step reduce the working time and driving over the field

• Special rotor shaft with spikes for stony conditions

• Ridge shaping in various sizes, optimum adaption to the cultivation conditions

• Even depth guidance also in changing conditions, via different support wheels in front and rear of the rotary tiller

• Guiding disc for stabilisation on slopes

• Reinforced gearbox for up to 500 HP tractor power
