With the price of OEM Cub Cadet gear reducers up over $250 has anyone that just needed slower due to taller tires used a jack shaft setup to achieve reduction. There is plenty of room and if a sprocket is roll pinned to the front input of the transmission. And the same to the middle roll pin position of the driveshaft (adding a support bearing on the tail of the driveshaft). And then mount a jack shaft with more sprockets. Looking to achieve about 2:1 or even 3:1 reduction over all. I don't ever need faster, my property is an obstacle course and 2nd gear is already too quick to use with my 25x10-12s. I looked at the transmission cut away and the input shaft already has support.

Hi Casey

Ya, I was describing the creeper assembly in the first sentence. I don't want to spend that much.

Ya, I think I might aim to get 3:1 overall reduction. I see I have limited space but do believe using sprockets and chain I can get slower easily. I have three gears and 1st is about as fast as I like to drive with 25 inch tall tires. I have a pair of 26 inch tall I would like to run instead but I need to lose some speed first. Definitely going to add plate steel to the top and sides of the tunnel to add some peace of mind if a chain were to fail for any reason. Considering 35 chain though.

You could change the ring and pinion gears in the rear.

 

 

I forget what gear set they used but it might be easier than a jack shaft.

 

 

 

 

Edit:

Never mind lol

 

Pinion gear can't be changed.1 Piece gear.

Some Cub Cadets can interchange with early Dodge Dart and Plymouth Valiant. I think they had a 6 1/4" ring gear.. Should be 1966 and older. This info is based on a foggy memory so keep that in mind and do your research. In my 66 Cuda I had 3.91 gears and removed 3.23's. I think 3.56's were also available.
