jd 3520 HST open station turf tires air seat jd 997 ztrak 72"
hi dconine, on the one i just installed on my 3520 there is a vertical tab on the fore/aft adjustment lever that you move to allow the seat to move slightly fore and aft to soften the up and down movement when going over rough terrain. hope this helps...............bud
Hey bud, the only thing that I see is the knob for raising and lowering the air pressure & the lever for sliding the seat back & forth. Am I missing something?
