How to choose the right finger weeder

Peter de Haan|6 minutes to read

The finger weeders are designed to reduce weed infestation in the area close to the crops where metal shares cannot reach. The highest weed control efficacy can be achieved when weeds are still plants in emerging. Further on, it is important that the crops are already further grown than the unwanted plants to prevent damage. The finger weeders are a versatile and unpropelled tool that can be equipped with different types and sizes of stars and will be pulled attached at a hoe frame.

1. The correct finger weeder

In order to achieve a high weed control efficacy, it is important to choose the right type and size of the finger weeder. Generally, there are two model groups: First, the finger stars for smaller diameters for field crops and vegetables, grown under arable conditions. Secondly, the big models to hoe vineyards, orchards, or tree nurseries. Choose a model that is suitable for  the soil type and the crop row distance. Three different colours represent the grade of the finger weeder’s material flexibility.

Orange (soft) for sandy soil types and/or susceptible crops
Yellow (medium) most common flex type for field crops and vegetables
Red (hard) heavy soil types and stones. Standard model for vineyard

The correct diameter of the finger weeder is defined by the space between two crop rows. In field crops and vegetables, it is important to always leave space between the finger star and the adjacent row to prevent damage to the crop leaves. In vineyards and orchards, there is limited space between the tractor and the rows. In that case, it is recommended to use the biggest size available. The bigger the diameter of the finger weeder, the better the soil is worked.  The overview down below helps you to find the right diameter finger weeder for your crop type: 

Diameter Row distance Typically used 
250 mm 250-350 mm Vegetable 
310 mm 350-500 mm Suger beet 
370 mm >500 mm Corn 
540 mm >900 mm Vineyard 
700 mm >1800 mm Vineyard 
950 mm >1800 mm Orchard/Tree nursery 

2. The correct tool carrier 

There are tool carriers for all types of well-known tool bars as well as for any dimensions of square tubes. This allows easy updating of an existing hoe setup to enable a higher weed control efficacy around the crops.

Tool carriers: Available for every type of toolbar

Tool carriers

The tool carriers can be mounted at omega shape tool bars, like K.U.L.T. Argus and Schmotzer and former Rau brand hoes. As well they fit on the K.U.L.T. Habicht system, the Hatzenbichler toolbar, and Einboeck hoes. Further on, it can be mounted at square tubes from Carree or Monosem or any other square tube between 80-180 mm.

The Maxi finger weeder models fit any 50x50 pocket or square tube. They can be ordered with an adjustable shank or a cross bar to use them on any common hoeing setup.

Maxi: 50x50 mm cross bracket or bar
Cross connector
