How to Grow More Vegetables

One easy carrying position. Be careful with tines, especially near your feet.
The U-bar is balanced so its weight will be evenly dispersed.

The designers of the U-bar found that a 2-foot-wide
tool with 18-inch-long tines is as large as the U-bar can
be made. Otherwise it becomes too diCcult for a person
of average size and strength to operate.
The frame of the U-bar is 1¼-inch-square tubing with
a wall thickness of 0.095 inches. The elbow and brace
pieces are 1-inch-square tubing of the same thickness.
The frame material is hot-rolled, low-carbon steel, also
known as “mild” steel or 1010/1020 steel.
The tines of the U-bar are half-round bar, plow steel
stock. If plow steel is unavailable, use cold-rolled steel.
