I ended up jacking up the traction unit and using my creeper to reach and remove 4 bolts that held the heat shield in place. I was able to pull it out far enough to reach the missing plug and then install it.
Much more effort than I expected. But now I’ve got fresh plugs, air filter, oil &...
I have a Toro commercial mower 74180 and went to change the spark plugs.
The rear plug was annoying enough because I had to remove the battery to get clearance to get it out, and the front is worse.
I was able to pull the front plug, but could not thread the front plug to tighten it...
