The DirtWhacker System is exceptionally accommodating of mechanical joints because of it’s:

– non aggressive blade angle
– blunt leading-edge blade
– parallelogram-mounted blade that moves back and down with a minimum of resistance

However, to further enhance blade and mechanical joint life, the DirtWhacker Clip-Avoidance System detects the mechanical joint using an inductive sensor, and momentarily reduces pressure in the air bladder allowing the joint to pass over the cleaner blades with a minimum of resistance And interference.
