Central ND | Currently have the heavy duty downforce springs and have considered going to pneumatic airbags. My question is that in the JD manuals they state that the heavy duty downforce springs can do 400lbs of downforce and the air bags at max pressure of 120psi can only do 450lbs of downforce. Switching to air bags, doesn't seem worth the time and effort then if that's the case. Would I be better off just adding the helper springs between the parallel arms? Thoughts? Thanks. | |
