Victa lawn mower
(重定向自Victa)
The Victa lawn mower was invented in 1952, in the backyard of Mervyn Victor Richardson in Concord, Australia.
In 1951, Mervyn's son Garry mowed lawns to earn money in university holidays. Garry borrowed Mervyn's cylinder-based power mower which was heavy to transport and to operate. Mervyn wanted to design a new mower for his son's business. Mervyn had seen Lawrence Hall's 'Mowhall' rotary lawn mower demonstrated in 1948. The heavy Mowhall was not a very successful invention because it required two people to use it, one to push and one to pull.
