Multi Spike 1200

The Multi Spike, with four optional types of knives and spoon tines, improves soil drainage. The rear roller assures a safe operation, and its adjustment sets the working depth accurately. For general aeration, the standard 1/8-inch (3 millimeter) thick triangular knife will give you 8-inch (200 millimeter) deep slits at a close 6-inch (150 millimeter) spacing, while the fine slitting drum will give you 4-inch (100 millimeter) deep slits at an extra close 3-inch (75 millimeter) spacing.
