If you're not aware, you can redeem multiple promo codes at Green Farm Parts. For example, you can utilize the "GTT" code to receive a now 7% discount and you can add "GAUGE" for a mower height gauge ($200 minimum order) and "STEERING" for a suicide knob ($400 minimum order).
That being said, I'm acquiring a bit of a surplus of the mower height gauges. I'm offering them for free on a first come, first serve basis for the actual cost of shipping. PM me if you want one and make a reply indicating such on this thread, so folks know when to stop after the third reply, as that is how many I have to give away.
