HARVEST FEEDER CHAIN

It seems to us that most feeder chains were designed in Fred Flintstone's day. They are heavy and cause premature wear on the drive mechanism and feeder house bottom.

They often wear out sprockets and stretch chains prematurely because of their weight. The slats are virtually impossible to straighten and because they are riveted you are almost forced into buying a new feeder chain every time a slat bends.

In 1991 Harvest developed and marketed the first plastic slatted feeder chain.

HARVEST offers a Feeder Chain that will handle today's larger crops, improve feeding, last longer and reduce maintenance costs. It starts with 557 chain. With heavier rollers and side links it will outlast the original chain by hundreds of hours.

The slats are bolted, not riveted. The slats are made of plastic with a spring steel insert, giving the slat flexibility as well as "memory" so that when it is bent it will return to its original shape. The plastic slats have a trailing edge so when the flap goes around the drive sprocket it acts like a flipper and speeds up to force your crop into the threshing cylinder.

There are also fewer slats. We've taken away enough to reduce the weight but left plenty to carry any crop, including western Canadian spring wheat. With fewer slats we've reduced the weight by 35%. With less weight you'll notice less wear on the bearings, sprockets and feeder house bottom.

This is how it works :

As the trailing edge of the slat goes around the drive sprocket it acts like a flipper and speeds up to force your crop into the threshing area the first time around. The design of the slat makes it impossible for your crop to follow it back around. Back feeding is eliminated.

Over the years there have been many weak imitations but for long term durability and true value, nothing compares to the HARVEST Feeder Chain.
