This broom is designed to be pulled by a golf cart. The handle, with a hole to mount to a hitch pin, is at a right angle to pull the broom efficiently. Polypropylene fibers are durable and just the right stiffness to do a geat job. The broom is also weighted to do the maximum amount of levelling without moving too much material. 511T differs from the 411T as it has double the brushes, two aluminum strips mounted together giving 6 rows of fibers.
