Rakes or tedders - design features and manufacturing principles

A tractor rake is an indispensable thing when collecting hay. Due to the manufacturing features and ease of use, rakes and tedders quickly collect hay using a tractor or walk-behind tractor. Actually, there is no significant difference between rakes and tedders. Their main purpose is to rake up the mown grass and collect the finished product. Mounted rakes/tedders for the tractor can be purchased at a specialized store or made with your own hands.

Description

This turner attachment is designed to perform two tasks:

• tedding hay;
• raking it to one side.

The working part of this type of tractor-mounted equipment (Russian, Finnish, Polish or Turkish) in most cases consists of four or five wheels. They all rotate in the same direction in a plane that is perpendicular to the direction of movement of the mini tractor.

In this case, the outermost wheel is slightly ahead of the others, the second is slightly behind, the third is even further, then the fourth and fifth. They all rotate in the same direction.

Each wheel has many metal rods around its perimeter, which are slightly curved at the edge in the shape of a hook.

Tedder rake

In raking mode, work occurs as follows.

The wheels, according to the instructions, rotate in such a way that the very first wheel, located on the right (if you face the direction of movement), picks up the hay scattered on the surface of the ground with metal rods and throws it to the side so that it falls under the second wheel. Then in exactly the same way he throws it under the third, then under the fourth, then under the fifth. The last wheel throws the hay to the left, where it, having been collected from the entire working strip of the rake-tedder, is folded into one row.

There are several options for working:

1. You can make one pass, then in the opposite direction, so that all the hay ends up in one row, where it will be much easier to collect.
2. You can make three passes in one direction, gradually moving the collected hay in one direction. In this case, you will have to collect three times as much hay from one row.

There are other possible operating schemes that can be followed on the tedder rake in this mode.

In the tedding mode, the tractor driver rotates the frame with impellers 180 degrees. In this case, the rightmost wheel will be located at the rear. The hay he picks up will not fall on other wheels. The same can be said about each of the wheels.

2. PURPOSE OF RAKE-TEDDERS

Rake-tedders are designed for tedding mown low-stemmed plants (grass, alfalfa, clover), which are dried on the field, as well as for raking already dry hay into oblong shafts. A tedder rake can also be used to rake up crop residues such as straw after harvesting. Rake tedders can be used on fields and meadows with a slope of no more than 12 degrees, in the absence of large stones, uneven surfaces and other unmarked obstacles.

3. SAFE WORKING CONDITIONS

To prevent accidents and injuries when servicing mounted rakes, the following recommendations must be strictly adhered to:

— servicing of the rake-tedder should only be entrusted to an experienced tractor driver who has read the operating instructions;

— all work related to adjustment and repair work can only be carried out with the tractor engine turned off and the device lowered;

— during transportation on roads, the speed should not exceed 15 km/h;

— when driving on a poor-quality surface, the speed should be reduced accordingly;

— no persons are allowed to remain on the rake-tedder during operation;

— rakes should be stored in a place that excludes the possibility of injury to people or animals;

— during prolonged downtime, the rake-tedder should be lowered to the ground.

All actions related to removing blockages and cleaning equipment must be carried out after the equipment has been lowered to the ground, with the engine turned off.

DANGERS:

- you should be careful about the protruding rods of the rake-tedder wheels - there is a possibility of injury

precautions must be taken when performing any actions near the wheels of the tedder; during transportation, the equipment protrudes significantly beyond the tractor on the right side; it is necessary to take into account the behavior of the equipment when maneuvering the tractor

Advantages

This technique (for example, GVK rake or Harvest rake) can be used to achieve the following goals:

1. After mowing, dry grass is located on the field chaotically, randomly. In order to collect hay, it needs to dry well. Here tedding can be used using such a hitch.
2. If the hay has already been collected in rows, sometimes you need to give it the opportunity to dry additionally. To do this, you can use trailed rakes to wrap the rows or simply scatter them.
3. The mowed grass can be raked into neat rows so that it is convenient to collect the hay after it has dried thoroughly.
4. When the hay has already been collected into windrows, it sometimes makes sense to combine two or more rows into one. This can also be done using a wheeled rake.

DIY tedder rake

On a note. Compared to using conventional tools, this attachment is much more effective. An additional advantage during operation is the ease of transporting the mechanism to the place of work.

Technical and operational parameters of tedders

The mechanisms indicated in the table are classified as mounted equipment, which is aggregated with a walk-behind tractor using adapters.

Classification

According to the method of operation, rakes and tedders are divided into:

1. Wheel-finger devices. The main disadvantage of this type of unit is that it is not designed to work with wet or wet material. The advantages include the practicality and high performance of such devices.
2. Drum mounted rake. They have other names: rotary or rotary rakes. Their wheels (using rotors) are located independently of each other. The advantage of this design is its high reliability. This type has the highest cost compared to similar units. Such rakes are capable of forming windrows from hay. In tooth agitators, the rings rotate in a horizontal plane. They are actually several metal rods, with several hooks hanging down from each of them.
3. In dental devices in the Russian Federation, the basis is a design in the form of the letter “T”. Metal rods bent in a semicircle, with the convex part up, are attached to a short crossbar located perpendicular to the direction of movement. When the hooks are lowered to the ground, they rake the hay. If they are lifted, a neat windrow remains on the ground.

Rake for walk-behind tractor

Preparatory work

Rotary rakes/tedders

Any farmer can learn how to make a tractor rake with his own hands. If a person already has the skill to handle or create such equipment, making a hay tedder for a tractor yourself will not be difficult. In order to make a rotary tedder yourself, you need to make a metal frame from a round and angular pipe. The rotor, without which the tedder process becomes impossible, can be easily replaced with the rear axle of a regular car.

Before starting work, it is necessary to sketch out drawings that will gradually be implemented into the design. If you are making a hay rake for a tractor, it is important to install a reduction gearbox on the power take-off shaft. In many tractor machines, the number of shaft revolutions per minute is approximately 540. And this is already an impressive figure for turners. 10 tubes in the shape of a “sun” are welded to the machine disk. The rake teeth are made of strong steel and are attached to the rotor using a welding machine.

Principle of operation

The attachment consists of a frame on which several wheels are located. Moreover, each of them is located slightly behind in relation to the previous one. During operation, they are installed so that their ends touch the hay rods and begin to rotate.

Arrangement of rakes and tedders

Work occurs in raking or tedding mode. In the first case, as a result of rotation, the hay raised into the air by the front wheel falls under the second. Then it moves to the third, fourth, fifth wheel and ends up on the left side of the rake. The hay collected in one row can then be collected with minimal effort.

In tedding mode, you need to rotate the frame with wheels 180 degrees, after which the rightmost wheel will be at the back. When rotating, the hay will not fall onto the wheel. It will fly into the air and fall to the ground in a new position. Tedding is intended to improve the quality of drying hay.

Tractor rake

Purpose of tedder rake

This is a special tool that farmers use when preparing livestock feed, drying hay, and harvesting it.

The devices are installed on:

• tractors;
• mini tractors;
• monoblocks.

When the tractor drives across the field, the tedders rake up the grass, collecting it almost completely.

The technology saves farms time spent on work and also increases the amount of hay harvested.

Since the structure's capture area is large, the loss of mown grass is minimal.

DIY tedder rake

Such equipment may be unaffordable for some farmers. In this case, it makes sense to make your own solar rake. The “Solnyshko” model rake-turner is perfect.

The “Solnyshko” rake is a wheel-finger device. For a Russian mini tractor, it is recommended to use a five-wheeled model. You can make it yourself.

Before work you need to prepare:

1. A frame that can be taken from an old motorcycle.
2. The wire from which the hooks for raking hay will be assembled.
3. Steel sheets. 4 wheels will be made from them.
4. You will need the brackets needed to secure the wheels. For each of them you need to take two bearings.
5. Parts with which you will need to assemble the hitch structure for attaching to a mini tractor.

For finger wheels, you can use, for example, hubs from Zhiguli.

Rotation is transmitted using a homemade gimbal-type design; for this you can use Italian equipment.

Attaching a tedder rake will help dry and collect the hay. At the same time, the use of such a trailer will provide a significant gain in efficiency and productivity.

Manufacturing process

Homemade tedders are easy to use, however, repairs may require the services of a specialist - especially if the rakes were made from low-quality materials.

The manufacture of mounted wheel tedders is carried out mainly for mini tractors and walk-behind tractors. A three-wheeled tedder is used for walk-behind tractors, and a five-wheeled one is used for tractors. To start making a tedder, you need to prepare the following tools:

• Metal pipe.
• Wire up to 0.7 cm thick.
• Steel layers 3-4 mm thick.

A frame is made from a pipe, and brackets are placed on it. Wheels are attached to them. Special bends are made from wire - “fingers”, designed for raking the mown grass. They are attached to the disks with special bolts. To install the wheels, two bearings installed in the hubs are useful. After this, the hitch is made, and only then the rake is installed on the tractor.

Properly made rakes and tedders will help make the process of collecting and tedding hay easier, as well as baling it. Rotary models are distinguished by their careful handling of crops that require careful assembly (such crops, for example, include alfalfa). Tractors with tedders easily cope with heavy work: turning over and collecting wet, heavy hay.
