Here are pictures of the original top link assembly.
This rotates the top of the tiller out away from the tires, as the 3-point is raised.

Comments:
* This link was original on a YM2000. It was needed on my YM240 (YM2000 US version) to clear the 24 inch tires. But running the tiller on the much smaller YM186D shown here that has 16 inch tires, there's more room between the tiller and the tires.
*Also shown is the PTO extender (brass color) given me by the tiller seller. The driveline was originally too short, likely shortened to make room for an overrun clutch. The US Yanmars have an overrun clutch inside the PTO so I needed this extender to make up for not running an external overrun clutch.
*The device clipped on the top of the tiller is my weed cleanout tool. A linoleum knife driven into a piece of conduit. This tool will reach the center of the tiller from either side, and it's easy to use reaching in from behind the tiller.
*I've learned that mowing a week before tilling works better than trying to till tall weeds into the soil, standing weeds get all snarled up in the tines.
