Question about Craftsman 8.50 Torque Rating Dual Rotating Tine Tiller

1 Answer

I have a craftsman cultivator, 2 hp model 536.292522. the engine runs, but the tines only turn untill they touch the ground, then they stop. does anyone know how the centrifugal(?) clutch works? does it have some kind of pad on it or is it steel on steel?

    Same problem here. It is that brass gear on the main drive shaft. I was able to easily press it off. I contacted sears and they said I had to buy the whole tranny for 200.00 or something crazy.

    I have the same problem and get the same answers. If some one would come forward and tell who supplies this part or even who makes the assembly. It seems stupid to me to make that the weak link and then not supply it. I have gone to the gear suppliers and they laugh when they see the gear.

The centrifugal clutch is steel on steel, if the tines are turning at all, the clutch is okay. unfortunately, what you are describing is a worn sector or pinion gear inside the transmission. not difficult to repair but time consuming and pretty expensive

If you cant move the tines by hand then I wouldn't think you sheared the pins, more like a gear box problem.

Just bought an older Mantis 2 cycle tiller. The tines engage when the tiller is started. Of course that makes it hard to start with the tines on the ground! I don't believe it was doing this when I...

if the idle is too high the tines wont stop due to the tiller tines are run by a "centrifuigual clutch" which means when you increase the throttle speed the tines will start to turn : there are 2 adjustments you can try,1) adjust the idle screw under the carburetor where the throttle adjustment and a triangle piece of metal touch(your throttle cable wire will be attached to this triangle) ,if the triangle and idle adjustment don't touch and there's a gap between these 2 pieces close the gap by adjusting the 10mm adjusting nut,this will correctly set the idle #2) adjust the idle adjustment screw talked about above till the tines dont turn with throttle set at idle or lowest speed setting

Craftman Tiller Model # 9172933311 doesn't go into ground. Tines skirt over grass instead of digging into ground and removing grass.

need to use down force and pull back to offer resistance so tines dig into ground and not walk across area

Tines stop under load

you have to get someone with a big tractor to "break" the ground up first. A tiller is just that...Not a plow

Help, new craftsman rear tine tiller stopped tilling.

It sounds like the belt just stretched. Now you need to move the belt tensioner over to put more pressure on it.

Sounds like you are speaking of the float bowl.
It should not have a hole in it.
You could purchase the part from Sears or a small engine shop.
If it were mine, I'd remove the bowl, clean it, and patch with a gasoline impervious material such as JB weld.
