They come as a SET, meaning for both sides. They are interchangeable from side to side, one mounting is for deeper tilling and when you remove and swap sides they will not till as deep and also helps for removing weeds, grass and the like.
These tines ONLY fit Mantis Tillers to my knowledge. You will need to order what you need from Craftsman, Google the model # of your tiller or use the part # of the tines to find a suitable replacement.
If the tines get stuck and stop turning and you have the motor running fast, the gear box is bad and will need replaced or rebuilt. Please note motor must be running at full throttle or close to it in order for the tines to turn properly. If they stop turning while tilling as I said the gear box is bad. This question has several alternatives. It could be they stop because of roots wound around the tines and make it too tight to turn. Need more info to answer correctly, several other possibilities .
Yes, it will fit the Mantis tiller, gas and electric.
Yes indeed it will.
Due to a technical issue the answer to this question was not posted; our apology. For those who are viewing this question, Mantis offers replacement tines for the 9" wide and 16" wide 7000 series models.
The tines are compatible with Mantis 7000 series 9" wide tillers.
