Tim tuned Stargrazer

Tim L tuned the Stargrazer ride-on mower at the CAO.

Something was different about the mower lately. It was running much faster! At first, I thought the motor had opened up, perhaps with all the tuning we had done. But it was a transmission issue. Normally, we'd cut at speed 3 or 4 but it was far too fast now. Even dialled all the way back to 1 was quick.

Tim and I chatted Friday night. I told him where the mower manual, with exploded diagrams, was. And I studied the e-copy to find the relevant pages.

In the end, he found that the Speed Control Rod ferrule was not positioned properly. He backed it off 10 turns. Which got things back to normal. But he's at the end of the threaded rod. He's concerned that something else is out of adjustment... He thinks we need to look at this some more.

Incidentally, in order to do that work, he removed the cutting deck. This gave an excellent opportunity to clean it thoroughly. He found some rust. He recommended we get some rust proofing stuff. And better cleaning tools.
