This style uses a 1981 Tempo transmission shift cable and a homemade return to neutral (RTN) device.

Tempo (or other approx. 42 inches long) shift cable mounted to the left side of the tower and attached to a bracket coming off the Hydro Control cross shaft.
8 1981 tempo shift cable 42 inches long.jpg
RTN mounted under the right foot rest. RTN and shift cable are attached to the bottom of the foot control assembly.
The adjustable rod from the RTN to foot control allows easy adjustment of the RTN neutral and the tractors neutral with brake pedal depressed. (Make sure the hydro does not creep prior to starting this project) The hardware sourced springs pull the hydro to neutral when you take your foot off the pedal (or spots in between). The springs need to be strong enough to do so. The pull on the RTN can be adjusted to your preference by the ΒΌ -20 adjusters and spring strength.
Back off the friction lock, as it is not needed and makes it easier for the RTN to do its job. A Damper was not needed. I suspect the shift cable served that purpose. I used a new shift cable $30 or so from e-bay. But that was a few years ago. After trooping around a number of junk yards and going thru the effort of removing what turned out to be a junk cable, it was worth the $$.

I no longer have this tractor but this setup worked well for a number of years. I used this one mostly for blowing snow. If I use one like this again (RTN under the foot rest) for snow duty I would figure out a way to keep the slush and salt etc. off of it.
