314-8

[Wendell 1]

New to the forum, but not to Wheel Horse. I just bought a 314-8 on the gear shift pattern there is what Toro calls a spring shift control, my 312-8 doesn't have this The 314 is a 1999, what was the purpose for this. Thanks.

I think to help prevent shifting while moving because you have to come to a complete stop to shift. Do you have any pictures of the spring?

Welcome to the forum.

Is there a part number on this decal?

I don't know how to post pictures, just graduated from a flip phone. Toro shows part # 99-8028 spring shift control. Item #50 under Hoodstand, console assembly. Over time it has wore a groove in the gear shift lever. Just curious of what the spring shift control was supposed to do.

I don't have any tractors with spring shift. Tagging along to hear the answer.

Spring - shift control or shift control spring

They added a switch to the gear transmission shift linkage to make the NMIR (No mow in reverse) system work. The spring likely has something to do with keeping the shifter in the reverse position so it is not confused with 3rd gear shifter position.

I did something similar but simpler many years ago to control a backup lamp - used a reed switch with a magnet mounted on the shifter.

Just pulled up the wiring diagram for the '99 314-8 and that NMIR setup sure does add some complications!

 

Then went to the IPL. From the little I can discern, it looks like a way to prevent (or strongly discourage?) the shifter from going into Reverse when the PTO is engaged. From the shape of the spring, I can see that it might put wear on the shifter lever--especially if it isn't aligned correctly or if the shifter was being forced into reverse while the PTO was engaged.
