7mm or 8mm Tines, that is the question?

Many farmers automatically believe that the 8mm tine will do a better job because it is stronger. That's not necessarily the case!. The key to making the best job with your harrow is getting the tines to do the work. A spring tine is designed to "spring" causing the point to oscillate from side to side. On a Grass Harrow this makes sure all the ground is covered by the tines and achieves the maximum effect from one pass. In many cases the 8mm tine can be too rigid and simply drag through the sward in a straight line with no "spring" effect. As a general rule of thumb choose the 7mm tine when you are predominantly working on temporary grassland (leys under 5 years) which is being regularly cut for silage, grazed and managed. Choose an 8mm tine when you are using the harrow on old permanent pastures and rough grazing in the main.
