Underground Installation - Vibratory Plow Movement

Handling obstructions

If obstructions (tree roots, large rocks, etc.) are encountered, disengage the transmission, turn the engine off and

then disengage the clutch. NEVER BACK THE PLOW WITH CABLE IN THE FEED TUBE. This will damage the

cable and pack dirt into the feed tube.

Carefully dig a pit behind the blade. Remove the cable, then remove the obstruction. Replace the cable and

proceed with the installation.

Although aggressively steering and lifting/lowering the blade are considered poor practice, these techniques can

be used as long as extreme caution is exercised.

Turning

Gentle turns can be made over a distance of 5 - 8 feet (1.5 - 2.4 meters). Never turn the blade unless the tractor

is moving forward. Some manufacturers make steerable blades.

Lifting the blade

If absolutely necessary (for instance, avoiding a buried utility line), the blade can be gradually raised at a rate of 8

inches (20 cm) over a 5 foot (1.5 meter) run. Lower the blade at the same rate once the underground hazard has

been passed. Do not raise the blade to ground level with cable in the feed tube.
