NRH Engineering has launched a new range of crimper roller, designed to create a weed-suppressing mat from cover crops without using chemicals.
The Bruzer crimper rollers are available in working widths from three to six metres. Constructed around a 406mm diameter tube, that can be ballasted, blades are made of Hardox and measure 125mm in length. These are arranged in a chevron pattern, spaced 150mm apart. The frame is made of 8mm wall box section and is self-steering.
The company says crimping is an established practice in the USA and is growing in popularity in the UK. It adds it has received an increasing number of enquiries from farmers who are considering crimping as a way of reducing their use of chemicals and tillage.
As well as killing the cover crop, crimping improves soil health as nutrients from the crimped crop filters into the soil, the firm says. The new machine will roll, cut and bruise the crop and is designed to work with direct drills to plant seed directly into the mulch mat. Prices start at £6,550 for a three metre set.
