That sounds like a great modification to the RBM2000! The increased power requirement of 130 CV suggests that the RBM2000 will be able to handle even more demanding tasks with efficiency. The addition of a US wheel set with a 6-wheel configuration will improve stability and traction, making it easier to navigate various terrains.
The optional back triangle is a useful addition that would provide additional support and increase the overall functionality of the RBM2000. This will be especially beneficial when working in challenging conditions or when transporting heavy loads.
With a capacity of 24 round balls, the RBM2000 is well-equipped to handle a significant amount of material, making it a versatile and efficient tool for farming operations. The price of $50,500 seems fair considering the enhancements made to the RBM2000, making it a valuable investment for farmers looking to improve their efficiency and productivity.
