I'm looking for a new chainsaw chain for an 18" saw and I just noticed that there is a different amount of links on the replacement chains. I'm seeing "62 drive link" "66 drive link" "72 drive link"
I'm not really sure what that is all about, but for what it is worth all I'm doing is cutting down trees and I would like a chain that would allow me to do this as quickly as possible

I am not exactly sure. I thought that it would say on the chains box if it would fit your brand of saw. Other than that you have to know the length of your bar (18" in your case). I just go to STIHL and get the chain for mine, since that is were I bought it. By the way, I'm not ordnance  ETA: sorry about the complete lack of help, I am sure someone will be along shortly that knows |

Count the number of links on your old chain and buy accordingly. Seriously, that's how it's done. Also the width and pitch of the cutting teeth may be different. Most homeowner saws are 30 deg pitch and 5/8" or 3/8" IIRC.
Check the faq at stihl.com for specifics. |

yep.
figure out which one is best for you. nothing worse than a goofy chain when you're trying to drop a tree. it could even get downright dangerous if the tree falls on ya! don't let a crappy chain saw make a tree a "Widowmaker!" I am not kidding; I have dropped 40" diameter trees, 50-60 ' high in snow back up North. It's no picnic. buy the best chain you can: Oregon Chainsaws |
| You need to write down the brand and model # of your saw and take it with you to the store. You can't just slap any chain on there. Tooth size and spacing as well as sprocket size are specific to your saw. Higher HP saws have more teeth closer together and your saw may not pull an incorrect chain. |

Chain pitch is the answer. For your small saw, it will either be 3/8" or 0.325". You will want it to match your drive sprocket and bar.
Click me has some good information. |

Drive links are the part that rides in the groove of the bar. The sprocket drives the chain by the drive links.
Count the # of drive links. Pitch is the distance measured between any 3 rivets in the chain divided by 2 (the distance between any 2 is not the same). Most homeowner saws use .325 pitch chain. Higher end (pro) saws use 3/8 pitch chain. Many bars have the necessary information engraved or etched on the bar. It is easiest to take your saw or your present chain to the saw shop to make sure you get the right one. Paul |

You also need to make sure you get the right chain gauge, which is width of the tang of the drive link. If you use the wrong one it will ruin a bar in a hurry. |
