Below the top-soil in rice paddies, there is a layer called the sub-soil.
Secures the soil’s bearing capacity during tractor work
Secures the soil’s water-holding capacity
Maintains the effect of fertilizers and agricultural chemicals
Working with a heavy tractor can destroy the sub-soil.
The lightweight design of Kubota tractor prevents the sub-soil from being destroyed, so work can be accomplished with confidence.
Cultivators can’t be used following extended periods of rain, and they suffer from poor shank penetration when the soil is too hard, preventing proper tillage during dry weather. When there are only about 20 days between harvesting and planting depending on the weather, the tilling by a 4WD tractor with a rotary lets you work systematically, regardless of the weather.
Cultivators use a 2WD drive and suffer from poor balance, making them prone to turning over when moving between fields.
The weight of cage wheels makes them dangerous to attach and detach. Moreover, excessive vibration during road travel makes for an uncomfortable ride, requiring that they be moved at low speeds.
By contrast， the combination of Kubota’s 4WD tractor and rotary tiller features good weight balance and safe operation.
