The bottom blade evolves after 190 years
Since the invention of the first lawnmower by Edwin Budding in 1830 the bottom blade or bed knife has not changed in 190 years .
To our knowledge the blade has always been manufactured with one cutting side and only a single set of holes to screw the blade into the blade carrier .
The first fine cutting golf greens mowers arrived on the world market around 1920 and have since then been constantly improved and refined , however the bottom blade remained unchanged in its design .
Donovan Ritchie the “ inventor ” re- engineered the bottom blade by adding a second row of holes and thus making the blade a mirror image of itself reinventing the blade forever .
TURF MANAGEMENT
South Africa was the testing ground as Donovan is a South Africa businessman , the blades have been tested and sold to the SA golf course market since the patents were approved in 2019 .
Our blades have proven to be of the highest quality with the top golf courses using the reversible blade , to date we have not lost a customer back to the OEMs or to any aftermarket manufactures “ why would they go backwards “
The blades are manufactured from a spring type steel with a high carbon content .
Our blades will not vary more than a 1 / 4 mm over its entire length making back lapping to a minimum if at all required .
No other manufacture has ever manufactured a greens mower bottom blade that can be used twice therefore our blade is effectively 2 in 1 .
The reversible blade has been patented in the UK , all EU countries , USA , China and South Africa with Australia , Canada and others pending .
The reversible bottom blades replace Toro , John Deere , Jacobsen , and Baroness greens mower blades .
Ritchie & ritchie products won the saltex 2021 machinenary catogory innovation award taking first place .
