There are adjustments for that. Plenty of help on this forum, but best to start a new thread if you need it.

Replaced shifter knob
 

Today, my cub has a new shift knob. Every little part helps! :)

Well, excellent choice to tap those holes. I've done that, like 10 times. LOL. Makes it so easy. I use 1/4-20 Phillips head screws. A long screwdriver reaches those pesky front screws easily.

As to the speed issue, remove the tunnel cover and adjust the length of the rod that runs from the speed control column to the hydro's cam plate. Might want to check the hydro's trunnion while you are at it. A common wear point that often needs attention and repair to get consistent hydro speed control and it's possible something has been jury-rigged there as well. The tech library has lots of stuff on trunnion repairs.

Good luck!

Many thanks!.. I actually enjoy tinkering on this tractor.. by the way, I finished installing the 2in wheel spacers for a total of 4in of added track.

Woke up yesterday to 5 inches of snow (and still falling) that I didn't believe was actually coming, so I didn't have the plow on. :bash2:
Shoveled a couple driveways by hand, then spent the twilight hours wrestling the plow onto the 122. Got it on, then found out the battery was dead. The dumdum who ran it last left the key in the on position after shutting off the gas.
So, this morning, with the snow STILL falling (up to about 8 inches now, maybe more) fired it up, grabbed my girlfriend for ballast (don't own any weights) and plowed our 500 foot driveway, as well as two neighbors.
Got done, into the field for some fun driving, and she promptly threw a tire. The wheel was turning, the tire was not. :bash2:
So, now, she's tarped up until the snow stops falling and/or I can dig the spare wheels and tires out of the storage area.
Anyone know what size the rears are for a 122? Mine have been on since before my dad bought her almost 30 years ago, before I was born, and the numbers are all but illegible. All I can make out is "Goodyear"
:bigthink:

Depends on what size rims are on the tractor;.
Picture???

LOL thats funny. Cool GF to ride with you. My ol lady rode on my lap the other day on the 100. :) (Not easy to make that work but it was fun!) I was told that skinny ags with lots of weight are best for plowing. But its really about weight mostly I think. I use all inner tubes in everything to avoid flats, add some strength, and better for liquid filling.

For tires on my 123 I bought 23X8.50-12 ag tires. I have the wider rear wheels. The skinny rears on my 100 model use 6-12 tires.

These are the 123's tires i bought:

Yeah, riding double on a single seat is not easy. I have a 2x12 plank in place of a seat just for carrying a passenger, so we both rode sidesaddle, she operated the lift lever, leaving me free to shift, throttle, and steer.
Mine has turf tires, not ag, but they are definitely not as wide as the ones you said you put on the 123. The 6-12's look pretty close. It's a place to start, anyhow! I may not replace it if it didn't take too much damage, maybe
a tube. Thank you for the size marks!

Let's see...what did I do today on the Cub? Tried to get it to start...most unsuccessfully. Same for yesterday.

picked up 2/17/2021 took carb off its full of the magic green stuff hahhahh.
fuel in the top hole fired up so its a plus.
