Multi-Spike
For general aeration, the standard 1/8" (3mm) thick
triangular knife will give you 8" (200mm) deep slits at a close
6" (150mm) spacing,while the fine slitting drum will give you
4" (100mm) deep slits at an extra close 3" (75mm) spacing.
For maximum penetration, even in hard ground, we
recommend the optional hydraulic weight system.
