L=8 lead, Fastest
LI=6 lead, Intermediate
LS= 4 lead, slowest
Swiftmatic Hi axle =L speed
swiftmatic Lo axle = LS speed
The gear reduction wheels Take a L and give it the ground speed of the LS. Gear reduction wheels usually bring $250USD and up on ebay over here. I picked up a swiftmatic (Swifty) for less than $150 and I love it. I had almost given up on using my Gravely because it would beat you to death and try to run over you. They swifty changed my opinion of the machine.
The first three pics are looking down on the axle. Its caked in mud but it shows the pivot and push rod that shifts the fork inside the axle. The 4th and 5th is from the engine looking forward onto the axle , the 6th shows how the lever is connected to the spring loaded rod, and last is a pic of the hitch frame. I believe your second pic in the first post shows this.
PS. Forgot to mention that the Gear lever also controls the PTO speed, LO Gear is lower PTO rpms and Hi gear gives a faster PTO speed. The swifty only controls ground speed.

I spoke with the guy who used to maintain it and he said the M.A.G engine was installed about 30 years ago to replace a gravely engine for reasons long forgotten.
I would just like to thank everyone again for your assistance :smile1:

It sounds like you got a great deal in the tractor and attachments, I am glad to see you keeping the old iron running.
