Ogano, knowing that Honda had never before developed a lawn mower, began to feel pressure from within the company and outside. Among the influences were several flawed propositions and critical comments concerning the possible drawbacks. Therefore, Ogano had to work on his drawing in order to prove that each of these difficult problems had been resolved. For example, in response to a group of people who said the machine should have a seat so that the user could mow more comfortably, he attached an office chair to a prototype machine and demonstrated how its lack of stability would compromise safety. It was, after all, a lawn mower equipped with large blades.
As a solution to the limited capacity of the bag attachment, which would of course quickly fill with mowed grass, Ogano was instructed to add a function allowing the machine to store more grass by burning or drying the cut grass using heat from the muffler. To prove that idea wrong, he explained that grass is more than 90 percent water and presented the results of a calculation showing the amount of energy required simply to evaporate the water.
One particular opinion held that progress in biotechnology would soon create lawns having very limited growth, making lawn mowers obsolete. To counter the opinion, Ogano planted a lawn in a small space in his backyard in order to observe its growth. As the seasons progressed, the grass began to grow rapidly. As he mowed his lawn, he experienced a sense of satisfaction-a pleasantly refreshing feeling-that he was communing with nature. He was convinced the need for lawn mowers would never diminish as long as people continued to experience the joys they could not get from maintenance-free biolawns. Through the experience he not only found a convincing counter-argument but gained considerable confidence in the product he was developing.
"To address various opinions and demonstrate the validity of our product development," Ogano recalled, "I made many field trips and studied relevant subjects so that I could convince them with total confidence. These efforts eventually led to the final result."
It was nearly the end of 1975, some time after Ogano had begun studying the machine's design, that he was told by Mr. Honda, then the company president, that resin should be used for the housing. Ogano rejected such an idea. "In order to start a lawn mower," he explained, "the owner will often place his foot on the housing to prevent the machine from being lifted as he cranks the motor. That's why using resin for the housing would be dangerous. If it were dented due to pressure, it might contact the blades beneath. So, even though it would be cheaper, resin shouldn't be used for reasons of safety. I just can't accept that suggestion."
Sixteen years later, in 1991, the U.S. corporation GE Plastics developed a resin having a level of strength equivalent to aluminum. With that, Honda became first in the lawn mower industry to employ resin in the manufacture of parts.
"When that happened," Ogano recalled, "I was impressed once again by the visionary thinking of Mr. Honda"
The basic structure's overall design thus having been completed, Ogano turned to the various functions his machine would need in order to outperform the competition. He was convinced that his new lawn mower would succeed in the market if it offered solutions to the problems that manufacturers in America and Europe had failed to address. Therefore, Ogano chose to design the lawnmower as a high-class machine having several key features:
| [1] |
Quiet operation, allowing the user to mow without disturbing the neighbors |
| [2] |
Safety embodying the concept of active safety |
| [3] |
Easy operation so that even a woman could easily handle it |
The process of trial and error was used to test various ideas and ensure that Ogano's goals would be met. For instance, a structure having the muffler tucked under the deck was examined in order to reduce engine noise. That idea was discarded, though, when it was found that trapped heat would kill the grass directly beneath the mower if the machine was allowed to run in a stationary position. Additionally, many hours were spent designing a mechanism to protect the user's legs against debris thrown up by the rotating blades. In order to guide the cut grass more smoothly into the bag, ways to improve the machine's vacuum efficiency were examined.
Safety was a primary concern, of course, so the machine was furnished with the world's first BBC (Blade Brake Clutch) mechanism. The system would automatically stop the blade rotation within three seconds if the user released his or her hands from the handlebar, meaning that the Honda's lawn mower could offer a degree of safety that no other manufacturer had even considered possible. In fact, the BBC mechanism played a role in the U.S. Government's enactment of a relevant CPSC (Consumer Product Safety Commission) regulatory safety standard. This technology gave Honda a dramatic lead over its competitors in the area of safety.
