If I am looking at a 58 Spartan 100 tandem dual, with three shift levers in the cab, what am I most likely looking at? Main, auxiliary, PTO, what? It’s not a 4 x 4. Seller has no clue and I can’t see the machine in person.
I would like to paste a picture, but don’t know how.

One could be a Brownie, one could be a PTO, plus main. Exercising lever might give clue by determining pattern?

Hy Mathew Blair and guys, the three levers in the cab are, left lever, transmission shift lever, center lever, declutching lever, right lever, power divider control lever. The operation of this power divider is a little different and there is no overdrive function. Hope that helps.

Like 3B said, you are looking at factory Power Divider shift levers (first introduced in Chevrolet trucks in 1956). The 3-speed Power Divider unit has one input shaft from the main transmission and two output shafts (one to each rear axle). The front axle is always engaged and the rear axle free wheels when rolling along on hard roads or engaged when off road or in a hard pull. The Power Divider has three gears, 2.22 under, 1.22 under and 1:1 Direct. It will more than likely have a Clark or Spicer 5-speed main transmission.

Finding a Chevrolet TF truck with factory tandems is a rare thing!
