1997 prairie Joy: 3way switch by brake lever, marked 'power - AT - Snow'
What's it for? What should be the default setting? Wires are connected
All three positions place the transmission into a different gear change pattern.
Power would hold the transmission in gear a little longer to create a sportier (if that’s possible) drive.
AT would be the standard position and provide a gear change to achieve the most economical driving pattern.
Snow would place the transmission into a higher gear (probably 2nd) to try and avoid wheel spin in icy conditions.
