German beet harvester Holmer Terra Dos T3

The Holmer company produces agricultural machinery and has branches around the world. By purchasing a Holmer T3 beet harvester, you can be confident in the quality of the machine, and also not worry if one of the components breaks down, since the company has many service centers in Russia.

Holmer T3 is a beet harvester, which is a device for harvesting beets and loading them onto transport. This technique is in demand in many farms.

The beet harvester can operate in difficult conditions, including frozen, rocky soil, uneven terrain, and an abundance of weeds. The uprooter, depending on the configuration, allows you to simultaneously process from 6 to 9 rows, which significantly reduces time costs. The special design of the uprooter eliminates the possibility of clogging it with soil: the plowshares are located in such a way that the layer of earth does not get stuck between the coulters. It is also possible to equip it with a lifter with a vibrating coulter, which further increases productivity.

Despite its large size, the Holmer T3 does not have a negative impact on the soil: large wheels and a fracture frame allow the weight of the machine to be evenly distributed over the surface of the earth.

The price for these agricultural machines is quite high, but not overpriced, because the Holmer T3 is a high-quality beet harvester with excellent performance characteristics and high productivity.

How does it work

There are 2 ways to operate the combine:

• thorny;
• with a preliminary cut.

The old method (pulling) involves extracting vegetables from the soil by holding them by the tops, which are cut off after removing the root crop inside the combine. The modern method (with a preliminary cut) is that the root crop is dug out of the soil without tops (they are cut off immediately) and cleaned. Extraction from the soil occurs through the work of diggers, which have several rows. This increases the speed of the combine and the efficiency of harvesting in one pass.

Tops can be disposed of in two ways. To obtain natural fertilizers, the tops are crushed and scattered against the direction of the machine. If the stems are to be used as animal feed, they are cut, unloaded and stored in boxes.

How it works

This machine can be self-propelled or work as a tractor trailer. The design consists of the following systems:

• device for cutting tops;
• device for digging beets;
• conveyor;
• lift.

The combine has a hopper for root crops, which can hold up to 30 tons of vegetables.

The working components of the unit have an electro-hydraulic drive.

The working width ranges from 1 to 12 rows. The vehicle speed is 10 km/h. Sometimes stationary installations are used, for example, the OVS-25 beet heap cleaner. The efficiency of the combine is 97% of the total amount of beets cultivated. The device has a self-propelled chassis to which working units are attached. The beets are collected in bins, from where they can be poured into containers for transportation.

HOLMER Terra Dos T-3 Self-propelled beet harvester

for harvesting beets, it is equipped with an expert-level uprooter; it works in the most difficult situations (snow, hilly soil, fields with a lot of mud). This technique exceeds all your wildest expectations! You should see all the best qualities of Terra Dos T3 for yourself.

The TerraDos T3 beet harvesting equipment is equipped with an expert level uprooter and works in the most difficult conditions (snow, hard and hilly soil, mud). This technique exceeds all your wildest expectations! You should see all the best qualities of Terra Dos T3 for yourself. Here are some of the few best qualities:

• Individual configurations, high performance, large sizes
• Working equipment for cleaning and uprooting
• Six, eight or nine row lifters
• The turning angle between the axes is sixty degrees – high maneuverability
• Low pressure on the soil is ensured by larger tires and driving with a breakable frame, as a result of which there is no damage to the soil
• Cabin designed for convenience and comfort
• Bunker with a capacity of twenty-eight cubic meters
• Efficient engine with 353 kilowatts (480 horsepower)
• Intelligent engine tuning in accordance with the load on the working equipment (1200 – 1600 rpm)

Characteristics of the HR lifter (DLG award)

• High-quality beet harvest in hilly soil
• The uprooter with coulter pairs allows for multi-row uprooting
• The lifter of this model prevents overloading of the combine by optimizing the depth when digging 100 tons of soil on each hectare with a depth of 1 cm)

Situations of clogging with earth are avoided thanks to the design of the coulter pair - the configuration of the shares has been improved, the resistance loads during work are minimized due to the fastening of the shares, and the rotational-translational motion of the vibrating coulters has been improved.

• For hard soil and high loads, an adapted bracket made of highly wear-resistant materials for fastening the plowshares.
• Reducing the number of vibrating coulter bearings results in less power used (ten percent less)
• Increased functionality and reduced weight by seven percent thanks to the use of fine-grained steel
• Reducing the number of consumable spare parts, fuel consumption, and losses during uprooting

Models and their parameters

Several combine harvester models are currently produced, the technical characteristics of which allow the following tasks to be performed:

• beet digger extracts vegetables from the soil,
• then the tops are cut,
• after this, the tops are unloaded onto a nearby trailer or scattered across the field,
• then the beets are cleaned through 8 spiral shafts, a separating elevator and 3 separating stars.

The weight of the combine is evenly distributed on both axles. Wide tires do not damage the soil. The beets are transported through the elevator into the bunker and then distributed using an auger. The hopper is emptied via a discharge belt. Unloading is accelerated due to the presence of a transverse and longitudinal scraper bottom.

The beet harvester has the following advantages:

• small turning radius;
• does not damage the soil;
• can move along an inclined plane if the axle supports are connected.

Let's look at the features of Holmer Terra Dos T2. The unit is equipped with a 338 kW engine. The combine has an automatic selection of the engine shaft rotation speed when moving forward or uprooting.

Holmer Terra Dos T2 has a two-speed distribution box with a hydraulic drive; the engine rotation speed and the machine drive are automatically controlled. Portal axles with steered wheels and brakes are installed at the front and rear. The front and rear axles are equipped with a transverse differential lock.

Beet harvester Kleine SF-10

The Franz Kleine beet harvester is a self-propelled unit that has the ability to reload beets into a vehicle moving nearby, as well as receive beets into an intermediate bunker; the latter allows the combine to cover large areas without stopping. Due to the large productivity over the area, the low level of cleaning costs, but at the same time its high quality, the “baby” from Klein convincingly demonstrates how high its efficiency is.

A well-thought-out alternative transfer scheme, either directly or via an intermediate hopper, ideally meets the requirements for sugar beet harvesting.

Technical features of the Klein combine

The beet harvester and digger are designed as two separate units. The topping machine is equipped with hydraulically controlled support wheels. The integral and serial topper is equipped with a topper chopping shaft, topper, topper and top trimmer mounted on a ski chassis. Adjustment of the cutting height and frequency, depending on the distance between the root crops in the row and the level of the root crop on the surface of the ground, can be set by the driver directly from the cab of the car. Thanks to the pressure accumulator, the topper is unloaded. Thus, the front support wheels only probe the soil and do not go into the ground, for example in rainy weather and damp soil.

In operation, the Franz Kleine SF 10 beet harvester impresses with its high maneuverability, as well as the high quality of the chassis and steering. The SF 10 owes its maneuverability primarily to its short wheelbase and large steering angle.

The hydrostatic drive of the chassis with a three-stage gearbox allows for infinitely variable speed control at each gearbox stage. In addition to steering the rear axle wheels when driving on the road, three control programs can be activated during digging via the graphical service terminal: all-wheel steering, dog-wheel steering, manual control via potentiometer.
