Description

<p>A compact cultivator called the Pianta that uses a gas canister was developed for use in kitchen gardens. </p><p>The butane in the gas canister undergoes phase transition between vapor phase and liquid phase at approximately 0°C under atmospheric pressure, so that fuel supply control and removal of fuel from the gas canister become theoretically difficult at an air temperature of around 0°C. The gas supply system uses the method of removing butane in the liquid phase. It also has a vaporizer placed between the cylinder head outlet and the muffler so that users can start and operate the cultivator during the planting season from March to April, when they start working with the cultivator in outside air temperatures of 5°C. </p><p>Compared to the FG201, a gasoline-fueled compact cultivator with the same engine displacement (49.4 cm3), the Pianta showed an approximately 10% reduction in CO2 emissions. The Pianta’s emission performance also met EPA Phase II regulation levels and Japan Land Engine Manufacturers Association self-regulating levels. </p><p>The overall width between the outer tines was reduced by 22% relative to the FG201 in order to make the Pianta easier to maneuver in the garden. However, the plow power was raised approximately 15% relative to the FG201 by the adoption of the new model tines and enhancement of the drag bar. The issue of noise when using the cultivator close to residential areas was also addressed by reducing the noise level at the operator’s position by 1.5 dB(A) during operation. </p>
