Tips & Warnings on Tillers
As an option, the tune-up may include replacing the tine assembly. A whole new tine assembly will make a huge difference in the performance of the tiller. The easiest way to tell if the tine assembly needs to be replaced is to look at the condition of the current set of tines. If most of the tine tips are rounded off and blunted, it is time to replace them. If the tips are bent over but in otherwise good condition, straighten the tips with a pair of pliers.
