No, but you could. The 15$ I spent you could not buy the parts to upgrade the farmertec, some did it in the early kit days, no problems. The case and gears are copies. It oils just like one made by Stihl, which in not enough in my opinion, I like my chain damp. Put a 20" and the sthil would have a damp chain, move up to 36" and not so much. I first noticed it on the 029. On a 16" bar it barely did it's job and you could see the effects on the bar. I guess it was use only enough to not impact the environment? I hated to see the Stihl bar degrade so I have paid attention. No other option on a 440. But the 660 ho works great on a 28 mine currently wears.
