When designing our harrow tine we tested many different types of steel hardness and thickness. Our testing showed that anything over 1/2" (.5") diameter was too sluggish and collected too much trash. Plus, mild steel is prone to wear prematurely and/or spread open. We attempted heat treating the tines, but like cast iron it made the tine too brittle and was prone to break when hit.
Therefore we decided to use a high-quality slimmer steel rod to form our tine. The high-quality rod, combined with our precise manufacturing techniques, creates a harrow tine that can last three times longer than inferior foreign imports.
We begin with a 1/2" (.5") 1038 carbon spring steel rod. The rod is then drawn (or pulled) through a .452" die. This is the real secret to our tine strength, because by drawing the steel it gives the steel rod an additional 20,000 lbs. tensile strength! By drawing the steel, rather than heat treating our tine, we increase the steel strength without compromising the steel's integrity.
We use a computerized bender to form the steel rod ensuring consistent form and function. This consistency allows our tines to wear at the same rate, which eliminates the need to replace individual tines. All tines are 4 1/2" long and are held at a 120 degree angle in the aggressive mode. The 120 degree angle creates the perfect balance between penetration and trash clearance.
Each harrow section comes in seamless single widths, so there is no streaking, no need to tie together sections, and no binding/tangling.
We offer two piece sections (front and rear) for our drawbar harrows, and single piece sections for our larger 3pt harrows, mounted harrows, and harrow carts. Instead of smaller old-style hooks that are placed through holes in the drawbar, we use welded front rings that wrap around the drawbar. The welded ring allows free movement to stop binding and premature wear, and also eliminates unhooking during use. The open rear rings are designed so they may be hooked and unhooked when needed, but not out in the field when the harrow is in use.
The tines can be pulled in the aggressive mode (tines standing up), less aggressive mode (tines laying flat), or upside down (tines pointing up in the air).
Who says that you can't find a quality American-made product anymore? While foreign manufacturers cut costs by using the cheapest materials and labor, we refuse to manufacture a product that wears out too quickly, breaks apart, or functions unevenly. Farm equipment isn't supposed to be disposable, and we have created a product that even our grandfathers would be proud of.
