2021 Grimme GB Series 330

The belt planter is the right choice to plant non calibrated seed potatoes, various sizes or longish varieties. Higher drive speed is possible with appropriate sizes as with a cup planter. The GB 330 is especially designed for 3-row planting into beds. Compared to other planting methods, a more uniform tuber growth is achieved due to optimised crop spacing within the bed. An increased quota of marketable yield is the result of an even growth of the tubers. The machine can be further upgraded with equipment such as a spreader for granulates, a fertiliser box, devices for liquid chemical treatment of the tubers and the GRIMME Flow Board.

Flow-Board for even covering of the planted tubers

Driving speed of up to 10 kmph realize a high output, depending on the crop size and variety, planting distance, machine equipment and soil conditions

Barrel system for liquid tuber dressing and furrow treatment as well as a fertilizer spreader for under-root fertilisation.

The spray track eradicators permit to create tramlines by clearing one third of a bed.

Steerable wheels offer advantages at the headlands and on slopes

For optimum adaptation to the tractor, the drawbar can be telescoped mechanically.

Features may include:

• During planting, the potatoes are first transferred from the hydraulic tipping hopper (1) onto two individual, hydraulically driven feeder belts (3). The filling level in the planting element can be adjusted in an infinitely variable manner from the operator terminal. The finger feelers (4) control the constant feed. For planting, the potatoes are placed onto the round belts (10). The regularity of the tuber spacing depends on the evenness of the tubers and the corresponding machine settings. Excess tubers roll off the side and are conveyed back in the direction of the coil roll (5) by closed return belts (7). From here the potatoes are returned onto the round belts (10).

• The tuber spacing and the number of tubers per hectare can be adjusted from the operator terminal.

• The feeding belts evenly fill the planting elements. This leads to an ideal singulation of the tubers on the round belt, which ensures an even planting result.

• Finger feeler detect and regulate the filling level in the planting element. This ensures an even supply of seed potatoes even on slopes.

• Six round belts, which rotate at different speed, transport the seed tubers centrally and closely lined up on the set of planting belts from the backside of the machine towards the furrow opener in the front. The differential speed of the round belts in relation to the return belts supports a good alignment of long potatoes on the set of round belts.

• The distance between the round belts can be adjusted to adapt to the tuber size. The adjustment can be done via an adjustment disc.

• The round belt agitator supports the singling of the seed potatoes on the round belts. Due to the possibility of a fast and sensitive adjustment of the agitator to the tuber size, the device is perfectly suitable for frequent change of different tuber varieties.
