What transaxle shaft type or size is on my mower? Racing Mower build.

Hello, I’m trying to build a racing lawnmower out of my 2006 23hp Troy-Bilt horse. Im planning on running a 40 series torque converter to a 7 or 8 inch pulley going to a 3.5 inch pulley on the transaxle. Unfortunately i cant figure out what size or the what type of shaft is on the axle. Im pretty new this kind of stuff so dont be to hard on me

transaxle model number: 618-04566A mower model number: 13АР60ТР766

thanks in advance!

Is it a keyed shaft or something else?

Input shaft keyed. Usually with Woodruff key.

Output axle shafts are either double "D" or keyed (long square key) at the wheels depending the equipment OEM specs. Most are double "D" with the rim being the key.
