Thanks for the pic!

I was looking at the service manual and kept seeing a nut at the bottom, I skimmed past the older setup with the bolt.

I tried to get at it, but didn't have any luck with my standard size wrenches. 3/8 was too big and 5/16 seemed too small. Either the nut it rounded off or it's an odd size (which I find unlikely considering I can disassemble this tractor with half a dozen wrenches lol)

Do you know off hand what size it is? I was trying an open end wrench, I'll try to get a socket back there and see if that helps.

Also, it looks like the back side of the bolt is a square drive? Does that sound right? Didn't look like an allen wrench.

But, I'm also afraid it's as tight as it's gonna get looking at the attached pic, it looks like the outer edges are already touching... Perhaps I can put some sort of a shim in there if I get it loose.

Thanks again for the help!

I don't recall what size it is. There is supposed to be a plastic sleeve on the shaft. If yours is gone, that explains why it is tightened down with the ends touching.

The newer 149s had the nut on the bottom They did A up grade

After I looked through the parts diagram I noticed a bushing should be there. My guess is it's gone, I'm hoping to get it apart soon and find out.

That's what I noticed. I'm trying to deal on a 1250 parts tractor. Could I swap the lever assembly from a 1250 into my 149?

The guy wants $100 for a 1250 w no engine or sidepanels and a handful of other odds and ends (wheels, battery tray, air filter etc) I think that's a little high, trying to get him down to $75.

your have to use the dash/tower off the 1250

I got the adjustment bolt out and removed the clip on the bottom of the speed control rod. I used a 11/32 socket and 1/8 allen wrench. Gonna get a new bolt and lock nut.

There was a bushing in there, but it's quite worn. I'm going to see if I can find something at a hardware store to replace it, the part is $7+ shipping. Looks like any 1/2"ID x 3/8" plastic bushing should work.

I looked and looked and couldn't find anything readily available to replace the bushing. I thought bushings for a toro axle might work, but I stopped at my local toro dealer and checked them out, too small.

I finally decided to use my WV ingenuity, and wrapped the bushing with electrical tape once around. It added just enough thickness so that I could tighten it down.

I drove the tractor a little bit this evening and the lever works much better. I just adjusted it by guessing on the tightness. The manual says 7-12 lbs of pull force to keep handle in motion.

It still seems to want to take off if I push the speed control above halfway and let go. But I didn't drive it much, so I can't really say. Perhaps I need to adjust the lever a little tighter?

I also need to adjust the brakes more. They don't do much right now. Trying to figure out the best option. They have a little pad left, but I am bottoming out on the adjusting nut. I hate to just keep adding spacers/washers to the rods. I think I may try to put something in front of the arm on the brake pads itself, adding a little thickness.

All in all though, I think it's ready to test out. I probably won't get a chance for a couple weeks.

Cub cadet warehouse has the bushing 7.50 but 10.00 shipping sucks
