Itd seem to me that an air ride would really set you up high. Unless theres a low profile model I havnt seen. Where I mow, its hard enough ducking under some branches now, I sure wouldnt care to set up any higher.
I swapped an air suspension base for the OEM mechanical one and re-used the seat. The seat itself is decent put the mechanical suspension is useless. At the time I spent CDN$600.
