The operation and application of hay rakes and hay tedders – Part 7: The rotary tedder and windrower
by GJ Stoltz (Reg Eng Tech) In the final article in our rake and tedder series we focus on rotary tedders and windrowers. The working principle of a rotary tedder is similar to that of a kitchen egg beater. The primary function of tedders is to spread the cut[...]
The operation and application of hay rakes and hay tedders – Part 6: The multiple-rotor rake
by GJ Stoltz (Reg Eng Tech) The brief time available for getting the forage harvest done makes it vital to achieve high work rates. A multiple-rotor rake gets the job done faster than rakes with only one or two rotors. We thank the ARC Agricultural Engineering in South Africa[...]
The operation and application of hay rakes and hay tedders
Part 4: The double rotor rake by GJ Stoltz (Reg Eng Tech) The double rotor rake is designed with two rotors next to each other, rotating in opposite directions to form a windrow between them. Double rotor rakes can also have their rotors placed behind each other (trailed) to[...]
The operation and application of hay rakes and hay tedders – Part 3: The single rotor rake components
by GJ Stoltz (Reg Eng Tech) This month we discuss windrow screens and safety guards, guide wheels, tine arms, carriers and the operational features of the single rotor rake. We thank the ARC Agricultural Engineering in South Africa for making their manual on rakes and tedders available to the[...]
The operation and application of hay rakes and hay tedders
by GJ Stoltz (Reg Eng Tech) Hay had to be raked with crude hand tools until the early 1800’s, when the horse-drawn sulky rake was developed. Rakes were developed to gather newly-cut hay into small piles, or windrows, to make hay collection easier. Rakes lift mowed hay from the[...]
