Blade versatility

Flail blade

Thatch is the dense layer of clippings, roots and stems that forms between the soil and the base of the grass. As thatch builds up, it prevents water, air and fertilizer from being absorbed into the soil. This causes shallow root development leading to vulnerability to drought and frost. Excessive thatch also creates an ideal environment for insects and lawn diseases. Power-raking with flail blades removes this thatch layer and restores your lawn to good health. Flail blades offer the most aggressive dethatching of all the blades offered.

Delta blade

Delta blades were created primarily for overseeding existing lawn. They effectively incorporate grass seed into the soil. This is an easy, reliable method for rejuvenating poor lawns. The delta blade is also useful as a vertical mower for cutting running stem grasses and opening up the soil to oxygen, water, nutrients and other chemicals. Delta blades are also beneficial on slopes, terraces and in high clay content soils where water runoff is a problem. Blades should penetrate the soil to a depth of 1/8" to 1/4" with a maximum penetration of 1/2". Check your seed bag for the manufacture’s recommended depth of application.

Spring tine

Ideal for the established lawn that is not in need of a complete renovation but requires dethatching (dry-spots, fungus, etc.). Spring tines are designed to pluck dead grass and thatch out of the lawn without tearing or damaging existing root structure. With the flexible tines, the lawn is combed only 0.5 cm into the soil, so it cannot penetrate the root structure. Spring tines provide less aggressive dethatching than flail blades.

Setting blade height

The blades are raised and lowered using a depth lever on the right side of the machine. The knob in front of the lever controls the depth. Turning the knob counterclockwise increases blade depth.
