How does a double knotter work?
How the double knotter works: The knotter feeds an upper and a lower twine to the bale as it is being pressed and ties the twine with two knots – one at the front end of the bale (starter knot no. The lower twine is threaded through the needle by a tensioning system that surrounds the base and the two ends of the bale.
Who invented the hay knotter?
In the 1860s, mechanical cutting devices were developed; from these came the modern devices including mechanical mowers and balers. In 1872, a reaper that used a knotter device to bundle and bind hay was invented by Charles Withington; this was commercialized in 1874 by Cyrus McCormick.
How does hydraulic bale tensioner work?
High pressure hydraulic oil from a pump applies an accurate, axial load to the fastener. Once the system reaches a predetermined pressure, the operator uses a small bar to run the nut down by hand. This is easily accomplished because there is no load on the nut.
What is a hay dog on a baler?
A hay dog, when operating as designed, serves to hold the hay in place when the plunger returns to the front of the baler. Without the hay dog, the hay would push the twine out of the way of the twine fingers or tucker fingers, when the needles deliver the twine to the knotters, causing a mis-tied bale.
Who invented the baler knotter?
Appleby knew that twine was the answer. He organized the Appleby Reaper Works in 1874 at Mazomanie, Wisconsin. After persistent experimenting, he patented the Appleby Knotter in 1878 and a binder in 1879. In 1881, Appleby sold his invention to Cyrus McCormick for $35,000.

How does hydraulic cam chain tensioner work?
A hydraulic tensioner includes a plunger with a distal end abutting the shoe. The plunger is movable within an opening formed in a tensioner body. The opening includes oil and a spring member therein to cushion chain loads transmitted through the shoe and plunger.
