GST BIOSTAR

Rethinking mechanical weed control

Perfect solution for organic and conventional farming

GST Biostar is a revolutionary agricultural machine that uses newly developed mechanical technology to control weeds.

Whether you’re operating a conventional or organic farm, GST Biostar offers an eco-friendly solution for weed control, delivering superior results compared to traditional spraying methods.

Achieve higher levels of precision and efficiency in your crop management, while ensuring a healthy and sustainable harvest with maximum yields, often less than 1% loss.

Specially developed for weed control

The rotary hoe breaks the surface and loosens the soil with the outer spades of the star wheel. The spades then remove or cover weeds in the early stages of growth without affecting crop growth. Thus, the soil is aerated and the weeds are dried out.

Furthermore, GST Biostar is not dependent on rows or row types, such as ridges and row spacing.

Optional equipment

Seeding equipment for cover crops and catch crops.
Can be supplied with air seeding equipment

Crops

GST Biostar can be used in virtually all crops, depending on the depth of seeding.

Sizes

GST Biostar is available in several sizes, specified in this diagram, or can be custom-made according to customer requirements.

Huge capacity

GST Biostar is one of the fastest weed control machines in the field.

Speeds of up to 25 km/h / 15 mph.

The cleaning effect has 100% contact with the surface, regardless of unevenness and foreign objects.

Minimal yield loss, often less than 1% per pass.

Top quality

The GST Biostar rotary tiller has been developed in collaboration with customers to ensure maximum value and quality.

With an extremely high-quality frame without any kind of support wheel, the cleaning effect is made more efficient.

FAQ

Can GST Biostar rotary tiller operate in all crops ?

Yes, virtually all crops to a certain height. GST Biostar digs up everything down to a depth of about 3 cm / 1.2 in, so when a plant has root growth deeper than 4 – 6 cm / 1.6 – 2.4 in, the machine can be used regardless of the crop.

Do you have to drive fast ?

Yes, the speed throws the soil on the tip of the star wheel up in the air, and spreads it over the smaller weeds that the star wheel do not dig up – the star wheels dig up about 30%, the rest is covered by soil. Speeds around 15 – 25 km/h / 9.3 – 15.5 mph is ideal.

What is the yield loss ?

The yield loss is dependent on your wheel fitment on the tractor and of course the crop you are working in. Under normal conditions it is typically 0-2% – add to this the positive effect of the loose soil crust which increases the utilization of nitrogen.

How does GST Biostar not damage the plants ?

GST Biostar’s star wheels are designed in a way that makes the machine gentle on the crop, as the crop needs to have a height of at least 3 cm / 1.2 in, which makes it possible for the crop to bend and avoid being uprooted by the machine.
