The realisation in the early 1930s that by putting holes in the ground, the grass grew better was the start of things for SISIS. A simple hand fork and aerators on wheeled hand frames were their first products when the company launched in 1932 and in 1934, the first SISIS horse-drawn aerator was sold to Doncaster racecourse. Since then Sisis has become a worldwide recognised brand as revered in North America as it is here at home and with a range to meet the challenges of greenkeeper and groundsman alike.
