If this helps / clarifies - The tractor is an E-14.  It was all original stock metalwork when running on lead acid. 
My first test run with the lithium, before I put the weights in the rear battery box, yeah, steering was more of a suggestion.

Interesting. I have found that with the rear bb600 battery box the tractor is difficult to steer without the deck slightly raised. Yes the springs are on

I used to use a frame with 2) 8x8x16 solid concrete blocks setting on 
it, right behind the rear battery box.  It made steering with the mower 
deck nice, and made it possible to steer with the 42" snow thrower.  The 
wheel weights would only give more traction.  Once I converted to 
lithium batteries, I had to re arrange the weight distribution.  I no 
long use the weights on the rear, they are now in the rear battery box,
