This is the original arm assembly for shifting the transmission and someone has welded a bent piece of flat steel to it for a handle.
I cut the flat steel bar off and I had to use the torch to heat up the nut and bolt to separate the other pieces.
Here is the shifting arm assembly after it is cleaned up.
I'm using a pin instead of a nut and bolt to fasten the two pieces together and I made up a bushing that goes on the bolt on the top of the transmission for the pivot point.
This is a photo of an original walk behind Centaur tractor.
You can see the shift arm assembly bolted to the top of the transmission with a rod going back to a shift lever that is mounted in the center of the handle bars.
With the seat spring mounted on top of the transmission on my tractor, the shift arm has to point out the other way from the original location.
This is the neutral position.
Forward position.
And reverse position.
These are the individual parts that I have made up for the shifter handle and the mounting bracket.
The odd shaped bent flat steel bracket on the left is one end of a mounting bracket for a bottom roller on a boat trailer.
It already had a 1 inch hole in it so I found a 1 inch pin and two 1 inch bushings.
I cut a piece of pipe and turned the inside of each end out to the diameter of the brass bushings.
Then the bushings were pressed into each end.
This piece was then used as a guide for the depth for pressing the 1 inch pin into the flat steel bracket.
The pin is welded on the back side and the bracket is welded to the piece of flat steel to form the mounting bracket for the shifter handle.
The other parts were welded together to form the shifter handle assembly.
This was then mounted on top of the transmission, under the seat.
Here is a view of the linkage from the shift lever to the shift arm on the transmission.
The gear shifter works easily and smoothly.
