CombCut is a mechanical and selective weedcutter developed to comb Your crop and cut weeds in cereals, grassland and and other similar crops. Without herbicides you can use CombCut to weed crops when:
Products Details
- Crop is slender than the weed. And / or
- Weed is stiff and crop is not.
But of course you can also use CombCut to cut weeds above branched crops like canola, soy or coarse crops like some vegetables.
What weeds can you cut with CombCut?
CombCut is developed for weeding coarse weeds in crops like cereals, corn, native prairie and seeded grassland. But You can also use CombCut weeding some vegetable crops like beans, onions and carrots. If you don’t want (or cant) to use herbicides CombCut would be your choice. Even if our machine is developed for organic production it will also work well for the conventional grower. With CombCut you can weed many of the herbicide resistant weeds
Some weeds as examples
The weeds presented here with proof of concept will give you an idea of what kind of weeds CombCut will work on. Weeds and crops presented here are just some examples. There are many other weeds you can weed with CombCut but when you can see these results you can also imagine how to solve YOUR problems.
Wild mustard, Charlock. (Sinapis arvensis)
Claims and comments:
Wild mustard / charlock reduced with 70 – 80 % in first run. As always the results depends on timing and what crop you grow. Using CombCut also reduces the amount of seeds and therefore lessen the problems with wild mustard / charlock over the years.
Claims supported e.g. by:
(1) Our own field trials.
(2) Many growers using CombCut in Europe.

Claims and comments:
Using CombCut in Canadian thistle infested fields can increase yield withas much as 94% according to Swedish research. This number is of course depending on how bad the fields are infested with thistle but we have had very high numbers also from other sources. The above number 0f 94% comes from a 3 year field trial in barley conducted by the Swedish University of Agricultural Sciences.
Cutting is retarding the growth and development of Canadian thistle and reduces seed production significantly. Add in competition from a crop and the production of seeds will reduce additionally. ComCut can thus also be used to cut the flowers and seed heads to prevent seed dispersal. (87 – 100% reduction of produced flower buds)
Cutting reduces the amount of biomass (above-and underground) of Creeping thistle over time. Add in competition from a crop and it reduces the amount of produced biomass (Above-and underground) of weeds further. (68 to 89% reduction of above-ground dry matter (plant), and 66 to 79% reduction of underground dry weight (root)
Deep plowing is a good method to fight thistles in grain production, but it is costly and very energy consuming. Tests in 2014 in Norway with the selective weed cutter CombCut show that this may be an option to control the thistle in organic grain production. Using CombCut weeding Canadian Thistles in oat increased yield with 39%.
