Hello, This drill works only in very fine sand should be avoided in the earth unless modified several things. 1- Recovery of soc with stainless steel to prevent wear 2- Return 180 degrees left wheel to increase the space between it and the plow if not the first small divot blocks the system. 3- Repeat the axis which is aluminum plastic to minimize mechanical games. After making these changes this planter works perfectly even in the ground with small clumps. For me the real price of this product should be 10 maximum. Sincerely.
