Balmer GM's guide to grinding
If your machine is no longer cutting the grass cleanly, its time to get the cutting units serviced and sharpened.
Balmers recommend a two tiered grinding strategy over the course of each year; a full relief grind when your machine is serviced over the Winter months and this then followed up with a mid-season spin grind to keep ensure optimum cut quality throughout the season when you need your machine the most.
