Good morning , can you give me the serial number or the year of unit .?
There is a bar code 21038 20017
Is there any trick to the adjustment of the cable? It seems that the harder you push on the main handlebar, the more you extend the cable and the more (or less) power is transmitted to the wheels. Where do you start?
You got any hints as to hooking the spring on the traction cable to the transmission arm? You have to fish the spring and turn it 90 degrees in order to hook it on the arm.
There must be a simple technique, I just haven't found it yet.
I finally fished the hook on the spring onto the transmission arm. However, now there seems to be way too much slack in the cable up at the handlebar. There is a clamp to adjust the cable sheath below the handle but I cannot tell what is correct or not. At some point in the adjustment the mower cannot be pulled in the reverse direction. (That obviously is too much!) At the other adjustment positions there seems to be way too much slack and I can't tell when it is giving me assist or not.
Seems like there ought to be an adjustment procedure.
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."
I appreciate the time you are putting into my question(s). The Toro system is quite subtle in that you never get the impression that you are chasing the mower. You are always putting some effort into making the mower go forward.
Before the cable broke there were many times that I wondered if the assist was actually working. However, when the cable attachment broke, it was a real bear pushing the mower around.
So maybe I am making too much of having to make the cable adjustment. There is at least 1 or 2 inches of wound bare cable sheath on the handle end of the cable that allows for that much adjustment. (The mower deck end is just a plastic snap-in connection with no adjustment possible.)
