Trouble Shifting Gears (Brand new 3 Stage)

I have 3 Stage 24 inch Cub Cadet brand new - used once for 30 minutes.

When I shift gears from Reverse to Forward the cable between the gear shift lever and the transmission becomes slack.
I have to manually reach down the turn the rod going into the transmission.

Also (while in forward) when I release the handle grip level the snowblower keeps going forward for 2-5 seconds before it disengages.

The dealer said he thinks it is because it is very cold out and I am in an unheated garage. After 30 minutes the unit still had this issue.

He wants me to remove the back plate and put some grease on the rod, or apply heat to that area.

Does this sound right?

No

Tell the dealer to come and get it and fix it, or at least attempt to fix it on-site

If thats going to take weeks upon weeks, take matters into your own hands and post some pics of where the cable goes into the transmission so we attempt to diagnose

It sounds like only an adjustment.

Forget the grease.

Look for any ice build up around the control cable ends first

Do you have a space heater like a kerosene fired space heater?

If not use a hair drier with a good heavy gauge wire extension cord to heat up the ends of the cables and linkages
and some motorcycle cable lube or Fluid Film will help lube up the cables in their sheathes.

The Fluid Film or PB Blaster will probably cost less than the motorcycle cable lube

What ever you do DO NOT leave the aerosol cans in an unheated garage as they will not be useable.
(do not ask how I know how not to do this)


Grease???!! my a**hat PPPFFFFFF!!!!!!!!!!!

Hi, welcome to the forum!

Both of the dealer's suggestions sound reasonable to me.

If the machine has a single cable from the shift lever, to the bottom of the machine, then it can only pull. So there is presumably a spring in the bottom of the machine that pulls the mechanism back in the other direction. My machines, as a contrasting example, have had a rod going from the shift lever down to the bottom of the machine, so they can both pull, and push, the mechanism. They therefore don't need a spring down inside the machine. If a spring is involved, then it can only do so much to move the shift mechanism. And if the cable is sticking, or if there is too much drag on the sliding components in the bottom of the machine, then maybe the spring can't keep things moving properly.

For it continuing to move after releasing the grip lever, that also sounds like a sticking cable, or something not moving freely in the bottom of the machine.

The cables could certainly be iced up. I assume it worked OK the first time, and is having problem now, on a subsequent use? If you can thaw the machine somewhere, that would help understand the problem. Opening the bottom of the machine, and adding a little grease to the sliding transmission parts, is also not a bad idea.

But this needs to be done a bit carefully. There will be a rubber wheel, which contacts a round plate. The friction between the two is what drives the transmission. So make sure the rubber wheel stays clean, and doesn't get any grease/oil on it, or the transmission will slip. I've used a thin coat of grease on the shaft that the rubber wheel slides along when changing gears. I'm assuming that your machine has a similar setup.

You mentioned that after 30 minutes you were still having the problem. Running and blowing snow won't do much to warm up the possibly-frozen parts, unfortunately. But if you could use an electric space heater to warm it for a few hours, that might thaw it.

I would suspect the spring for the shift lever under the bottom pan is not connected correctly. This cable does not need lube.
The shaft that the friction wheel slides on should be coated with a light film of Anti-Seize, not grease.

I've got an 11 year old Cub Cadet and they still use the same cable, brackets and linkage they've used for years. Works fine, still using my original cables, all I can say is lubrication is your friend, just make sure it's rated for cold weather use.
