For Farmers
AI in-row weeder: up to 90 % less hand weeding.
Machines with the Ullmanna AROW box inside hoe between the plants in the crop row from the two-leaf stage, without herbicides or hand crews. AROW is trained on 194 plants, and farms have relied on these machines season after season.
For Farmers
What a machine with AROW does on your farm
It works in row crops such as sugar beet, pumpkin, lettuce, onion, cabbage and many more. There is no calibration and no lengthy set-up: get on the tractor, select the crop and start hoeing. Heavy weed pressure on "bad" fields is no problem either.
- 99 % plant recognition
Even under high weed pressure, because the camera looks for the root point of each crop plant rather than the leaf.
- From the two-leaf stage
You can start hoeing when it matters most, which is also when hand crews are hardest to find.
- One 6-row machine, up to 60 workers
It removes up to 90 % of hand weeding. What a hand crew does in a day, the machine does before lunch.
- No herbicides
Mechanical hoeing in the row, right under the leaf, on organic and conventional farms.
- Day and night
The box has its own flash lighting, so it works in the dark, and neither wind nor low sun affects detection.
- Up to 5 km/h in the row
About one hectare per hour with six rows in sugar beet, and faster in wide-row crops such as pumpkin.

Here is how we calculated it, in four steps you can check against your own farm. The figures cover only five months of 2026, and the season is still running.
-
10,250 machine hours in five months of 2026 → hectares. Time per hectare depends on the crop: pumpkin and sugar beet about 0.5 h (wide rows, fast), cabbage, tomato and celery about 1 h, lettuce, onion and herbs about 1.3 h.
14,000 haweeded -
Hand weeding takes 40–230 h per hectare depending on the crop: pumpkin 40 h, lettuce 200 h, celery 230 h. The AI removes 78–97 % of that work.

Machines
Which machine is right for your farm?
Ullmanna does not build machines. Nine machinery manufacturers build them with the AROW box inside, from two-row vegetable hoes to twelve-row sugar beet frames. Tell us your crops, hectares and region, and we will connect you with the manufacturer whose machine fits your farm.
What farmers say
This weeder is the reason why our pumpkin weeding works so easily. We are so happy! This is the best device ever invented. This machine makes our life so much easier.
Even with just around 15 to 20 hectares of organic sugar beets, the machine pays for itself within four years. I’m also impressed that it can be operated day and night, as well as by the excellent support from the Ullmanna team.
Questions farmers ask
01How much manual labour can I save?
Up to 90 % of hand weeding. In 2026 the fleet removed 78–97 % of hand-weeding hours depending on the crop. One 6-row machine does the work of up to 60 hand workers.
02Which crops does it work in?
Sugar beet, pumpkin, lettuce, tomato, celery, cabbage, broccoli, onion, watermelon, fennel and more than 100 other crops, including herbs and specialty crops. Ask us about yours.
03When can I start weeding?
From the two-leaf stage. The cameras detect the root point, not the leaf, so wind and overlapping leaves are not a problem.
04How fast does it work?
Up to 5 km/h in sugar beet, which is about one hectare per hour with six rows. Faster in wide-row crops such as pumpkin.
05What tractor do I need?
A tractor with hydraulics and a battery supply. The manufacturer of the machine confirms the power class for your row count.
06Where can I buy a machine?
From the machinery manufacturers that build AROW into their machines. Ullmanna does not sell machines itself. Tell us your region and crops and we will put you in touch with the right manufacturer.
