Just as a Zamboni is used in a hockey game a harrow is used to resurface an equestrian arena when the surface becomes undesirable for competition. The current harrows that horse equestrian arenas use now are somewhat faulty. They leave footprints in the arena, don’t reach the sides of the arena and don’t mix the surface thoroughly, which makes riding in the arena unsafe. Our senior capstone team has been tasked with the creation of a new, more efficient harrowing device for horse equestrian. The goal is to design a harrow that can remove hoof imprints, smooth, re-level and compact the surface all in a timely manner, to keep the horses safe for competing.
