On August 5 and 6, a council of contractors held a public demonstration of slurry tankers in which a total of four distributors, including HFT, demonstrated five different slurry tankers before a large audience. A KAWECO slurry tanker that HFT demonstrated performed well, spraying accurately at the specified depth of 3cm in a hard (difficult-to-break) grass field that had not been tilled for many years. Other machines encountered some difficulty because of the conditions. The visitors applauded the KAWECO slurry tanker for its high level of performance.
