While farming using a regular (single shaft) rotavator, Gurpreet observed that conventional single shaft rotavator needs to be operated in 2-3 passes for efficient pulverization of soil in field. Gurpreet’s rotavator uses double rotating shafts for pulverizing the soil in a single pass. It is tractor (min 40hp) PTO powered rotavator, wherein both axles rotate in the same direction, at the same speed resulting in better pulverization of soil in single pass. It is available in size from 7 ft to 12 ft and different shapes of blades like L, J and C type can be attached to the rotor to pulverize the soil. It has been tested by NRFMTTI (Northern Region Farm Machinery Training and Testing Institute) and found to perform as per following specifications. Working width: 203 -205 mm, Speed of operation (kmph): 3.63-3.91, Field capacity: 0.629-0.734 ha/h; Field efficiency: 82.9-94.1%, Depth of cut: 6.0-6.3 mm, Fuel consumption: 5.90-6.29 lph.

Increased Efficiency: It achieves better pulverization of soil in a single pass, eliminating the need for 2-3 passes with a single axle rotavator. This saves time, fuel, and labor.Improved Field Capacity: It can cover more ground per hour (0.629-0.734 ha/h) compared to a single axle due to its single-pass efficiency.Reduced Fuel Consumption: Despite its increased functionality, it has a reported fuel consumption (5.90-6.29 lph) comparable to single axle rotavators.
