This new one I got doesn't have two holes in the linkage, just one.
This earlier message is too old for me to edit it, but I want to make a correction - my HRX217K6HYA DOES have two holes in the linkage, just like all the rest. I have no idea how I missed that. I also don't know why I bought it with 3 months to go before there will be any grass to mow. :smile:
