I have a 520H with the gear assisted steering and swept front axle with a Kwik-Way loader.
Have 6 40 lb suitcase weights hanging on a weight rack on the back of the tractor plus approximately 90 lb wheel weight.
You need some weight behind the axle to counterbalance the weight of the loader and anything you're carrying in it.
I've got a weight box but opted for the weight rack and suitcase weights, easier to load and unload to use on other tractors.
I currently have tri-ribs on the front running 30 lbs of pressure.
It steers good even with a load in the bucket if you are moving.
I have a spinner on the steering wheel and it steers easily with one hand.
Steers much easier than a C145 I had with the a snow blower on it running similar weight but with turf tires and regular steering.
You might talk with Kelly since he has a C195 with loader also.
He might be able to help you as to swapping in a gear assist steering system or power steering of some sort.
Seems like he was working on power steering for his C195.
