Performance

Golf tees can cause damage to mower blades resulting in costly repairs and regrinding of the blades. Reducing the energy required for the mower to cut the tees whilst still maintaining high durability for extended use to the golfer is a major challenge.

with its unique shaft geometry allows the mass of the tee to be substantially reduced without reducing stiffness and ductility. This reduction in the shaft cross sectional area makes the tees easier to cut by the mower with less chance for blade damage.

The following test data was obtained using a modified ASTM D4812 (ISO 180) unnotch impact test. This involves the use of a pendulum with a flat metal plate impacting the tee held in a vertical fixed position, the energy required to break the tee is then recorded. The following table shows the data obtained from testing 20 of each type of tee.

The test data confirms that less energy is required to break the golf tee under this test condition and hence less potential damage caused to the mower blade.

Even with this low energy, the golf tee is still extremely durable under normal golfing conditions and can last for 6 to more than 18 holes depending on the conditions and driver speed.
