The technology for knotting and tying
The system specialist
The processes of knotting and tying have a major impact on the overall performance and efficiency of a square baler. We offer technical solutions for different harvesting conditions worldwide. Our single and double knotters ensure tying systems operate reliably and effectively.

The best knotter
for each baler
The type of baler is important
Knotters are specified to the type and size of the baler. There are knotters for small balers and big balers. These baler types have different knotter compartments and produce various bale densities and annual outputs.
THINGS TO KNOW
How knotters work
STRING, LOOP AND HYBRID KNOTS
There are two ways of defining a knotter:
By the type of knot it produces or by the tying system.
There are three types of knots – string knots, loop knots and hybrid knots.
Loop knots
Cormick system
The tail is formed into a loop
The knot is made without straining the rope
Maximum utilization of twine strength
String knots
Deering system
The tail end is pulled through the knot
The twine strength is not fully utilized
Hybrid knots
Deering system
One tail end is formed to a loop
One tail end is pulled through the knot
No tail is cut off (Active Tailless Single Knotter technology)
One knot or two knots
The difference between the two tying systems lies in the number of knots produced.
Double knots have enormous advantages for high-density square balers.
Single knotter
Each knotter handles one twine
Each twine is tied into one knot
The tail is pinched by the retainer while the bale is being built in the chamber
Double knotter
Each knotter ties one twine which is split into an upper and lower thread
Each twine is tied into two knots
The twines are not under tension as the bale is being formed in the chamber

Knotter technology
Single knotters
Single knotters are typically used on balers with 2 or 3 knotters. HDC (High Duty Combination) variants are found on square balers where 4 to 6 knotters are arranged on each drive shaft.
For small and big balers
For hay, straw and silage bales
For high-density bales
Available with retrofit auto lubricator
Double knotters
Double knotters for high-density balers and high-duty knotter systems have up to 8 knotter modules on each drive shaft.
For big balers
For hay, straw and silage bales
For highest-density bales
HDC double knotter
Double loop knotter
