Spread Shingle Chips with a manure spreader, running tractor
engine at slightly more than idle. With tractor in low gear, keep moving
while spreading, applying a thin layer with each pass. Continue until
you have approximately a five inch base of loose shingle chips. Have
someone follow the spreader with a fork, shaking and leveling out any
lumps or high spots. This should be done during each spreader load.
Place shingle chips 10-12" thick over solid clay or hard top
soil. Spread Chips with a manure spreader.
