I went to Parts Tree and the number matches the part that I purchased locally.
This Toro traction assist system has me stumped! When the original cable broke I had no assist. (The cable was now perfectly slack.) More on this later.
There are two cables (one on each side) that are attached to a small diameter handle. The one on the left (traction control) is the one that broke. The sheath of the traction cable is attached to the stationary push bar on the mower. You must squeeze the small diameter handle up against the main handlebar in order to even start the engine. When you squeeze the small handle you are pulling on the traction cable. With the engine just running there does not seem to be any assist.
Now when you begin to push on the large handlebar it begins to slide down the push bar toward the mower and tension is eliminated from the traction cable. (At this time I do not seem to feel any assist even as I push the mower on my driveway pavement.)
I do know that adjusting the cable sheath and placing too much tension on the traction cable does not allow me to pull the mower backwards. It feels as if the transmission is locked or at least fully engaged. So this adjustment is obviously too far.
Here is the thing that has me confused. If eliminating tension from the cable provides assist. I should have had assist 100% of the time when the original cable broke. That definately was not the case.
So I know that too much tension engages the transmission. Too little tension or no tension does not seem to provide any assist. So there must be a "sweet spot" where the tension and the cable sheath adjustment needs to be located.
I am concerned that either extreme could damage the transmission. Where is the "sweet spot."
