The modifications you have made to the Iseki PRJ8D Rice planter sound impressive! By increasing the number of planters to cover a working width of 7.2m, you are effectively enhancing the efficiency of the machine. The expanded capacity of 72 saplings allows for planting more in a single run, further increasing productivity.
Doubling the engine power to 50 hp ensures that the machine can handle the additional workload efficiently. Increasing the driving speed to 30 km/h enables faster transportation between fields, reducing downtime. The larger 100L fuel capacity is beneficial for longer working hours without frequent refueling.
With the widened dimensions of 4m width and 4.2m length, the planter provides better stability and maneuverability in the field. Maintaining the original planting/working speed of 8 km/h ensures consistent planting quality while benefiting from the increased efficiency and capacity of the machine.
Overall, these enhancements make the Iseki PRJ8D PROx3 V1.0 a powerful and efficient rice planter that can significantly boost productivity in agricultural operations.
