Backhoe and tow bar

[chesternator]

Just getting around to this and it may be a question for RK tractor guy.

I purchased the backhoe for my RK37 and put it on myself. You cant really do it wrong but the factory hitch bar no longer fits after the modifications. It wont go in all the way due to hitting the existing bolts not newly installed bolts. I've definately seen tow bars still on with the backhoes on their lot but got me wondering if they modified something or replaced it with a shorter one
