Question about Power Tillers & Cultivators
SOURCE: Yard Machines/Tiller
the tines are usually connected with shear bolts designed to break away when u hit something as a safety precaution so that u dont break anything in the transmission. its common that people dont know this and replace them with normal bolts. if this was done and the tines are not moving now chances are uve got a snapped gear shaft

If you go to Sears.com, then go to parts,then type in the model number, then look to the right and scroll down slow you will see a spot that says get manuals for this model and click on view manuals then any manuals they have you can print them out.

I went to MTD web site and they had all the manuals for all there products. You will need a model and serial number to get them. Thank you for responding back to me.
I got the manual for the tiller and the engine.

The problem lies in the shift lever in the gearbox. A poor initial design that was upgraded twice. The shift fork arms have spread enough for pins to come out of the groove they run in when the tiller is shifted to the last position. (Bending back into position would only be a temporary fix as would not be any stronger.) To replace shift lever, the gearbox cover has to be opened. Seperating the cover can be somewhat challenging. When prying cover apart try to not damage the cover gasket. Gearbox grease is very thick, so gasket's real purpose is to keep water and contaminants out. Leave all gearing and chains in place. The shift lever part number is 618-0245B. Or use assembly kit number 753-0869 (contains shift lever 618-0245B, position indicator, and roll pin.) Part will run in the $56-$68 range and can be found through MTD as well as Cub Cadet. Also can get through Sears PartsDirect.

I had similar problem recently with 2007 Huskee MTD series 410. The shift assembly bent and couldn't move the clutch collar all the way over on the drive shaft.

The spring goes in first followed by the ball. The ball should not get in the key way because that is filled by the slider pins that go up into the spur gear that drives the tines. Actually the slider pins drive all of the gears by engaging different gears as the gear collar is moved up and down. The detent spring and ball is the mechanism that is supposed to hold the the clutch collar in place. Mine jumps out of gear when tilling any depth except very shallow. I have reinforced the shifting forks and replaced the pins on the end of it. I believe that the pins wear and the arms spread because i have to keep pressure on the shifting rod or it will jump out of gear when tilling. Even with the reinforcing, pressure on the shifting rod will wear out the pins on the shifting arm. This will be my 3rd reassembly and I am leaning toward the detent spring being weak and allowing the shifting collar to move too easily. I may order an new spring and ball and see if that helps. I am getting pretty good at taking it apart.
