The realisation that by putting holes in the ground encouraged better grass growth was the start of things for SISIS
A simple hand fork and aerators on wheeled frames were the first products.

In 1934, the first horse drawn aerator was sold to Doncaster Racecourse.

1938 saw the development of the Trulevel roller which had three rollers following each other, overriding hollows to give a true surface.

Innovations continued with the production of the first rotorake scarifier. The rotorake included the patented contra-rotation principle which is a series of blades rotating at high speed in the opposite direction to that of a conventional cylinder mower, pushing fibre away from the surface rather than into the surface.

It was developed following research at the Sports Turf Research Institute.

Saw the launch of the SISIS Contravator and Lospred.

The Contravator used strong contra rotating blades to cut grooves into the surface and the Lospred, utilising a system of twin neoprene rollers, dispensed the seed directly into the grooves with great accuracy ensuring the playing surface was preserved and germination was rapid.

The Autocrat was the first independently powered vertical action aerator to be launched in the UK in 1971.

New products continued with the Truline in 1972 which was developed in conjunction with a groundsman. It was a continuous belt system that gave a clear pained line.

1975 was the launch of a tractor mounted scarifier, called the Veemo. Produced for fast effective scarification of golf fairways, the Veemo has gone on to become a popular machine used across the world at golf clubs, sports clubs and public parks.

Specifically designed for the use on golf tees and greens, the Hydromain, produced in 1980 was the first comprehensive turf maintenance system. Highly manoeuvrable with a unique weight transfer system it used a range of various implements.

Later in the decade, the Quadraplay was introduced. It was a natural progression to develop a system that used a combination of implements ensuring multiple tasks could be carried out and a faster work rate.

The Quadraplay has gone on to become a staple piece of equipment in a ground teams fleet of machinery.

The new millennium saw no let up in innovation and new products that continued to help ground professionals in pursuit of their desired surfaces.

The Rotorake 600 with its contra rotating principle was developed as a heavy duty deep scarifier and linear aerator.

The Javelin Aer-aid system was developed to allow air to be injected directly into the root zone to speed up the aeration process, move air uniformly throughout the root zone for complete aeration, reduce compaction and increase water infiltration rates amongst the benefits.

SISIS was acquired by the Howardson Group to sit alongside Dennis Mowers, thus providing the groundcare industry with a truly comprehensive range of British manufactured products.

Later on in the year saw SISIS leave its long time home in Macclesfield and move to Kirk Langley to join up with the rest of the Howardson Group.

Due to initial request and demand from the USA, this towed interchangeable roller or brush unit was designed for fast and effective coverage of golf fairways and sports grounds.

Fitted with floating heads to allow it to follow ground contours, it is ideal for the removal of dew, striping for improved presentation, lifting grasses prior to cutting or brushing in top dressings.

SISIS celebrated 90 years of innovation and cutting edge ideas that has enabled them to build a reputation world wide for quality of product and service and helping grounds professionals to achieve their desired surface.

Our continuous journey will ensure the next range of product innovations are never far away.
