All four tines are different and cannot be interchanged. The tines must be correctly installed or the cultivator will not function properly. To till around plants or in small areas, the outside tines can be removed to reduce the tilling width to approximately 7 inches. WARNING: The tines are self sharpening and will become quite sharp from use. Handle carefully. The tines will all wear evenly. If the tines are being replaced because of wear, we recommend that all four tines be replaced at the same time. To replace the tines, do the following: Tine Removal 1. Put the on-off switch in the OFF position. 2. Disconnect the spark plug wire from the spark plug. 3. While wearing gloves, remove the hairpins and clevis pins that secure the tine assemblies to the shaft (see Figure 13). Remove the tines from one side of the unit.
