Dosko Stump Grinder modification

This is a modification I did on a Dosko Stump Grinder, originally there was a cable that engaged the cutting wheel, but because the cable siezes and the cable is not readily available in NZ, not to mention the price, I designed and installed this linkage system. Although this was not that cheap to do, the customer was very happy, with no problems after 2 years of heavy use.

You can see the linkage running down the handle from the control lever, pivoting off the handle pivot, to limit any adjustment when changing handle position. Any adjustment is easily done by twisting the knob on the top of the lever.

This is the second pivot, which travels down to the transmission.

This is a closer look at the first pivot. As you can see, I was giving the engine an oil change.
