That sounds like a great modification you made to the RBM2000 implement! The addition of the US wheels with 6 different configurations is a nice touch, providing users with more options to suit their preferences or specific needs. The optional rear wishbone is also a useful feature that can enhance the functionality of the implement.
With a price of $50,500, a required power of 130 hp, and a capacity of 24 round bales, the updated RBM2000 seems like a versatile and capable implement for handling bales in the field. Users will appreciate the customization options and the added flexibility these new features bring to the implement.
Overall, it seems like you've made some thoughtful enhancements to the RBM2000, and I'm sure it will be well-received by players looking for a reliable bale-handling solution in their farming operations. Great job on the modifications!
