Patent ID: 6860139

Claim:
A method of determining the green-speed of a golf putting green comprising: selecting a site on a putting green having a relatively flat surface; setting a green-speed reading apparatus including a rump having a raised start end and a ground contacting release end with a plurality of parallel, golf ball rolling tracks thereon, in a first direction whereby the release end of the ramp contacts the putting green surface at said selected site; placing and retaining at start positions a golf ball in each of said plurality of parallel golf ball rolling tracks, said start positions are at the raised start end of said tracks; releasing said plurality of golf balls from the start positions, allowing the balls to roll down said plurality of parallel track, by gravity onto the putting green surface; measuring the distance each ball rolls across the putting green from a slope line marked on the ramp; repeating the test with said apparatus facing in the opposite direction at said selected site and measuring the distance each ball rolls across the putting green from a slope line marked on the ramp; and calculating the average distance of all the golf balls rolled to determine a value in terms of green-speed.
