Default To fast maybe?

Hello,
Reading the specs on my 1250 it says it's supposed to do 8mph forward and 6 reverse. My 1250 seemed a lil quick on the gun for a lawn mower. Sometimes almost dangerous if you've got to much stick into it at the wrong time. Had a buddy follow me to see its speed, and I am running 23"'s instead of 20's, but 14 mph is humming at times. Nice for going down the road, but not so good when mowing down hill, you apply the over touchy brakes and fall into the throttle (OK now you see why I started the thread).

Did I put something together wrong when I reassembled the cub? Is this speed usual (and the tractor data site just plain wrong)?

Reverse seems about right speed wise I might add.

I mean the thing runs great since its overhaul and paint....I'd say like new. But man....it's a lil quick on the draw. If you throw the stick from stop to full power, it will squeal the 12" wide lawn turfs on concrete...Wasn't looking for a hotrod, just a decent mower....Think I'd rather have that speed turned into power....Things so touchy I don't trust letting anyone else mow with her...I mean that's not a bad thing...but still...

Did you do the hydro adjustments when you put it back together? Also a hydro doesn't mean cruise control, you will have to use the hydro lever too keep your speed adjusted continuously, especially if mowing up and down hills. Normally people don't use brakes on a hydro except for parking on a hill. Always use the lever to slow you down or speed yourself up. Is the trunion worn? Did you replace the trunion springs and end caps? Sorry for all the questions, I just have no idea of what you have done to the 1250.

Sounds like to me your hydro lever needs a bit more friction/resistance. I don't know how far apart you had the thing, but down inside the steering column where the hydro lever rod mounts up, you can tighten/loosen a nut to adjust the mechanism against a washer-shaped friction pad. You want to tighten it enough so when you go over some bumpy terrain the lever won't flop around or be easily jarred by a knee, etc.

This is a diagram for one of my machines, but yours might be similar. Part number 22 is the friction disk. Ditto on DX3's comments about relying on the hydro more than the brake. The end caps and springs he mentions are no. 3, 4, & 5.

That's not the parts diagram for a 1250, but yes I had all those linkages off (well to the point where it changes from the under column shifter like the 149 etc to the Ql type on side) and the trans removed during paint. The lever doesn't slip a bit. It's solid and stays at any speed you put it at.....It's just to fast. When most get on it, it's like the one gentleman said...Gives them whiplash.

Was thinking maybe I flipped a linkage around and it was pushing to far into the go position. I didn't really have internet access when I put it back together and just kinda played it by ear.....

If this is typical it is what it is......But there's a huge dif from 8 mph to 14. That's the difference from running to using a bike.....

Is there anyway to gear this down so you've got more available power then top end speed? Just can't see a need for it in my yard situation....

I didn't think it was possible for a stock hydro to go 14MPH with just the linkage adjusted wrong. But from what you describe it sounds like its hooked up wrong, otherwise you would go 14 forward and 0 reverse

It's stock hydro (far as I know), only thing that should effect it is the tire size....Unless I had something wrong...But I've got a fine reverse, and forward......And that 14mph is a definite speed, confirmed on a newer Honda digital speedo following me down the road. Not embellishing at all. We were laughing our buts off.


I know there's a speed control deal on the QL's (the little thumb screw and arm deal)....I seem to be missing mine. Guess that's a must have if I'm ever going to let the kids mow the lawn for me. Them tires will just shred the lawn...

I think you could sell the plans on how to make this "upgrade"!!

The main reason I like my Super is that it goes faster!!

I'd actually like a little more speed out of my 147..

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
