I never remove my blades either I actually sit on the floor with the head tilted all the way back and grind with a regular dewalt angle grinder, the straight grinder in the link would not work due to the angle. I now sharpen my blades either daily or after every job. It is quicker and the jobs go much faster with sharp blades. As for the angle on the blade I just eyeball it and it works fine, its not a perfect science, and you really now you done something when you finish.

Hello Tony,

We are a manufacturer of brushcutter-chippers where the cutting tools are also fixed knives, as on the Loftness machines (see www.deniscimaf.com).

What we supply our customer with every machine is a grinder made from a Komatsu Zenoa RedMax handheld brushcutter. We do the modification ourselves.

However, what is mostly important is the type of grinding disc. For our knives, the ones we ship with the grinders are for stainless steel sharpening. If it's not specified to be for stainless steel or harder material, it becomes too long to sharpen. Other than that, what you actually prefer to use to spin that disc is up to you...

On our blades, the angle of attack is important. Our studies showed that the most efficient angle of attack was within a range of only 6 degrees, so it's important to stay in that range to keep best productivity. I'm guess Loftness came with similar conclusions, and that they can supply you with a sharpening gauge similar to the one we send along with our grinders.


Hope this helps!
