How the iron blade of a spade is fixed to a wooden wheel?

The iron blade of a spade is typically fixed to a wooden wheel by means of a sturdy fastening system, which may include bolts or screws that secure the blade to a mounting bracket on the wheel. The blade is often designed with a specific shape to allow for a seamless fit against the wheel, ensuring stability and efficient force transfer during use. Additionally, the connection may be reinforced with adhesive or by shaping the blade to interlock with the wheel, enhancing durability during operation. Proper alignment and secure fastening are crucial for effective performance.
