ca tranny in a c

Justin SE IOWA · Feb 13, 2011

Will a tranny from a ca fit in a c? I want to make it go faster for tractor rides! Any ideas?

steve(ill) · Feb 13, 2011

yes it will fit. the CA is a 4 speed... but i think the 1st gear is extra low. Im not sure 4th is "fast".

CRS says top speed on the Model C is 8 mph, on the CA it is 11.25. Tire size will have an impact.

You C has the same final ratio as a CA. changing the trany will not make it go faster. to get the higher road speed of the CA you need to increase the RPM and install the bigger tires from a CA

thanks for your help!

The C is rated @ 1500 RPM, the CA @ 1650 RPM
here are the transmission ratios.
1st: C 2.5 mph, CA 2 mph
2nd: C 4 mph, CA 3.5 mph
3rd: C 7.5, CA 4.5 mph
4th CA 11.25
So you can see the difference in top speed is the transmission and the higher RPM on the CA.

I believe "high" (3rd in the C and 4th in the CA)are both direct so the difference in top gear between the C and CA has to be attributed to the larger tires and higher governed RPMs of the CA.
The CA 4 speeds give some more versality and allow more effective use of the engine's power.

Took my CA on my very first Tractor Ride. Did pretty good keeping up until lunch. After lunch had a plug fowl, cleaned it up and took off again. Never saw the rest of the folks until the afternoon break when they stopped and I caught up.
Ran it through radar once. 10mph with 12-4 tires.
Needless to say, never took it again. lol
