Hoeing systems
The HAK XHR-series parallel linkage can be fitted with several hoeing systems; a front hoe, a front hoe in combination with ploughing discs or a ridge hoe in combination with double discs.

Front hoes
When HAK invented the front hoe, a patent was obtained in 1927. The front hoe offers the possibility to weed both the trench and the side of the ridge. The HAK front hoes are available in various editions as well as various sizes. The adjustable edition is supplied with a heavy sharpened end, and is approximately 10 centimetres adjustable in width so the amount that needs to be weeded is reduced to a minimum.

Ploughing discs
The HAK ploughing discs are ideal for weeding the surface. The discs can be attached to the duo parallel linkage system or onto the frame. Depending on the ridge, two types of ploughing discs are available: row distance 50 and 75. The row distance of 50 centimetres has a steeper angle towards the ridge compared to the one of 75 centimetres.
