Hoeing systems
The HAK S-series parallel linkages can be fitted with several hoeing systems; a single hoe, one hoe and one disc hoe, three hoes, one hoe and two half hoes or vibrating hoes.

Hoes
HAK has over 80 years of experience in the fabrication of hoeing equipment. The hoes are made from high-quality low wear steel with a sharp cutting corner of 60° and are fitted with a forged steel handle. The HAK hoes prevent the forming of ridges and secure the surface to remain flat. The hoes are available and usually on stock in sizes (widths) from 8 to 67 centimetres with a handle of 30 by 10 millimetres. HAK also offers other handle sizes with a short delivery time. Although a single hoe is usually suitable for heavy surfaces, a formation with three hoes is advisable because three smaller hoes per row enter the ground more easily.

Half hoe or tilt hoe
For accurate hoeing close to the crop row, the half hoe is advised. Because of the continuous cutting side, it prevents the ground from bursting open. The hoe is twistable and adjustable in width.

Mono hoe
The HAK mono hoe can be used for precise and accurate hoeing, close to the crops. The HAK mono hoe is used for accurate hoeing purposes close to the crops. The centre placed shaft allows the left hoe to be used on the right side and vice versa. This allows the farmer to hoe up or down the ridge.

Disk hoe for plain field cultivation
By using the new HAK disc hoe, it is possible to weed even closer to the crops without the risk of fully removing the crops. Even in case of a steering error the disc will only (marginally) damage the crop. The discs are fitted with ball bearings and can be easily adjusted by use of a single bolt.

Vibrating hoes
The vibrating hoes comprise a socket with springing teeth which are fitted with a hoe blade. The blade is treated with tungsten in order to make it low wear. The vibrating hoe is very suitable for weeding heavy soil. In case of a vibrating hoe experiencing resistance, the tooth will bend backwards resulting in a steeper angle of the hoe towards the ground.
