Speed control problem with Craftsman self propelled mower

Hi all, please advise what could be the problem.

22'', 5.5 HP craftsman mower, the speed control, changes the idle speed from slow to fast (turtle to rabbit icons) does not effecet, other than that, it runs fine, but at full speed.

Does it like car's auto transimisstion? is it pricey to fix it?

I would need some advice.

Thanks all.

Couple of questions...

I'm not an expert - this just based on mowers I've used over the years...

What model is the mower?
Is it one of Craftsman's variable speed mowers?
Did it work before or is this a new mower to you?
Is there a seperate lever or handle to control speed?

I've never played with the variable speed mowers, all of the others I've had have one control that affects the engine speed/rpm and one that affects the speed of the self propelled. My mother in law has a variable speed Toro but I've never really looked at how it works.

Good luck, and I'm sure someone with more knowledge will be along but your answers to the above questions will help them.

My Toro and Murray self propelled front wheel drive mowers had
cable adjustments at the lever/actuator to engage the drive.
Maybe yours is similiar. It entails loosining a screw/bolt and moving cable back and forth till you get it the way you want.

Thanks.

So you have same situation that speed controller didn't work?

Mine will run at full speed after it gets started. How's yours? start idle then speed up?

The Murray starts at high speed then i thottle it back. The Toro engine speed is non-adjustable,but the mowing speed is.
Both cable adjustments.

Sounds like you're describing the engine speed, not the self propell wheel speed, correct? I'd bet you just have a broken throttle cable/control, or the screw that clamps it is loose.

For my situation, when engine runs at full speed, then the mower also drive fast, that means sell-propelled wheel speed also out of control.

How to test cable?
Is throttle cable easy to change by myself?

Is it expensive to replace controller?

Thx.

Sounds like a cable adjustment. whether yours has a "bail,or lever it sounds like you have to have somebody look at it.
!0 minute job for a mower shop and you may get it done for Zero
as a good will gesture.

Sounds to me that your problem with the engine speed (if that is the question here) is going be one of two things.The throttle cable is broken or clamp is lose as cheese pointed out,or for some reason the govenor spring is hanging on something and not working the govenor rod as it should.

In which case a throttle cable is a piece of cake to put on.
And if it's the spring,un hang it....whala.

craftsman mower self propelled wows

I have a similar problem. I have a Craftsman (Honda engine) bought around 2003 as I recall, Model No. 917.377792 21" cut. The self propelled feature is continually messed up. Wheels lock up, won't roll backwards, now won't roll forward most of the time, unless gear is engaged. Everything is just seized up. Actually took it to Sears service center. They did nothing except say, oh, that's a design defect, we see a lot of those, nothing we can do.
Can't imagine it can't be fixed. I've taken off the drive cover, and cleaned out all the grass that somehow collects there. The drive belt is in good shape.
any suggestions?
And new to this forum, thanks

I'd pull the drive wheels and have a look behind them at the gear drive parts. There are likely parts that need cleaning and lubrication.
