Final Drive on XT3 GSX

[J-Mech]

I want to know what the question really is, and the answer.

There is no "final drive" on a Cub Cadet. Not by a tractor standard anyway. If you wanted to be technical, the final drive would be the last reduction before the wheel. But there is one before that "final" reduction.
So, did you originally want to know the total reduction ratio between the hydro and the wheel? Or did you just want to know what the last reduction is?
Is the answer the "engineers" gave the ratio of the R/P? Or the total ratio between the hydro and the tire?





So, I made a quick trip to the parts book. I looked up the trans for an XT3. It shows all the gears, and the tooth count of all of them, minus the pinion gear on the hydro. (Says not available.) But I know the trans in the XT3 is the same as the trans in a 3235, so I looked it up. Low and behold, all part numbers are the same, but that diagram actually lists the gear on the hydro and gives the tooth count. So, in less than 10 min, I now know what the ratio of the hydro to the ring gear is, and the ratio of the ring gear to the "final drive"..... AND.... what the 27.7:1 ratio is that was stated by CCC! And I didn't have to make a phone call, or wait 6 days to get an answer.

Math and reading are so cool.

Thanks for doing that homework. I wasn't sure about the tranny in the 3000 series being the same. I guess to put it in simple terms, I am trying to find out the "power" or "torque" at the wheels or "whatever" the auto manufacturers are measuring it from. As an example, a Camero or Mustang might be listed as 300hp with 400 ftlbs of torque. That's what I'm trying to find for nothing more than curiosity. I did talk with my resident Mech Engineer at my work place, but he didn't have enough information on the tractor to be certain of the numbers he came up with. They seemed a bit high at 400plus ft lbs.

No other people on earth are more frustrating to talk to about mechanical things than engineers!!

Dude, a Camero or Mustang listed as 300HP and 400ftlbs of torque is completely different than a tractor. COMPLETELY. You cannot compare them. Cars and tractors measure output differently. Stop worrying about it anyway. Why is it even important?????

There is a reason mechanics and engineers don't drink in the same bars.

You're right, I should just let it go because I've been going in circles trying to find something. Bottom line is the tractor has plenty of power and it does what I ask it to do. Like I said earlier, my reason for knowing is nothing more than curiosity. Thanks again.
