How to Select Harvester Chains

The chain must be the correct size or pitch to fit on the sprocket. This measurement can be found on the chain drive link or by dividing the distance between three rivets by two.
The use of harvester measurement increases incentives for purchasers to preserve roundwood, improve their control over the supply chain, and increase their competitiveness. It also increases transparency and improves supplier relationships with industry.
Chain Pitch
Harvester chains are built to handle the demands of the work environment. These chains feature added precautionary features that help prevent operator downtime and offer best-in-class durability in heavy applications.
A chain's pitch is the distance between the center of two roller-pin or rivet points in a single link. To determine a chain's pitch, you can measure the middle points of three consecutive rivets and divide that number by 2.
For a more accurate measurement, you can use a gauge tool or ask a professional to take a look at your chain. Double-strand heavy roller chains have thicker side plates and can withstand high shock loads. These chains are ideal for heavier machinery and grills.
Chain Gauge
A chain's gauge is the thickness of the drive link where it fits into the guide bar groove. This measurement is usually stamped on the chain and in the manual. It should match the gauge of your guide bar. If you use a chain that is too thick for your saw's bar it could cause excessive wear and jumping off the guide bars.
Pitch and gauge are measurable by counting the distance between the center points of three rivets on your chain and dividing by two. You can also find this information in the first digit of the marketing number stamped on the chain and in your chainsaw's manual.
Chain Length
The chain length is an important factor to consider when selecting a harvester chain. It determines how long the chain can be before it needs to be sharpened. Ideally, you want to choose a chain with a length that will allow you to cut as much material as possible with each stroke of the saw.
