I have a B3030HSDC. :thumbsup:
Like you, I have and continue to experience what you have described. With a load in the FEL, no matter the weight on the rear, the steering is stiff at least, bordering on difficult as the load is increased.:confused2:
4x4 increases the steering resistance and when you add either asphalt or concrete as your driving surface, it is worse.
This has been my experience from pretty much the first day of ownership, and from my perspective, suggests I'm
1. overloaded,
2. under balanced,
3. or its the nature of the beast.
My machine has less then 80 hours on it and frankly, I don't find it any more then a minor annoyance...I just work around it.
I'll follow this thread just to make sure I'm not dealing with a future and potentially major failure, though I still have 2+ years of warranty left. :thumbsup:
