CLAAS threshing technology.

Two different threshing systems are available for the TUCANO. The choice is yours.

Crop flow.

Threshing system. ore pre-acceleration. APS.

Unique APS threshing system.

The distinct competitive edge of CLAAS appears well before the threshing drum. The dramatic acceleration of the crop flow from 3 m/s to 20 m/s enables a series of extremely efficient processes:

  • The pre-accelerator separates the crop
  • The crop flow is particularly even and up to 33% faster
  • Higher centrifugal forces sort considerably more grains
  • Up to 30% of all grains are already separated in the pre-separation concave directly below the accelerator, significantly reducing the load on the main concave

Thus there is a net performance increase of up to 20% with no rise in fuel consumption. APS really pays off.

TUCANO 400-300

Conventional threshing system. TUCANO 340 / 320.

The champion in all fields.

A high-quality threshing unit must remove and separate grains reliably in all harvest conditions. The classic CLAAS threshing mechanism provides impressive proof of its abilities time and again. Regardless of the harvesting challenges you face, it has the versatility to take them in its stride with the full threshing drum width of 1.58 m (TUCANO 340) as well as with the smaller 1.32 m version (TUCANO 320).

  • The threshing unit can be accessed easily from the front via the feed rake and from both sides through large openings
  • The extremely robust design of all the drives, and of the threshing drum drive in particular, ensures top reliability during the harvest

From field beans to clover seeds: the MULTICROP concave can handle anything.

The concave below the threshing drum is designed as a MULTICROP concave with individual segments that can be changed easily. You can switch the concave quickly for a wide assortment of crops, different varieties or various stages of ripeness - always ensuring the right combination of clean threshing, protective handling of the crop and a high separation rate.

Plastic preparation floor.

The preparation floor feeds the separated grains from the threshing system and the returns pan to the upper sieve and so enables initial pre-sorting of grain and chaff. Very moist conditions or a very high proportion of green growth place a heavy load on the preparation floor. The individual floor steps can be pulled out to the front through the stone trap for checking and cleaning. In this way, the even loading of the cleaning system can be ensured at all times.

TUCANO 400-300

Hydraulic concave adjustment and overload protection.

In the TUCANO 340 and 320 models, the concave gap is also set in CEBIS. The hydraulic overload protection also protects the conventional threshing system from damage by foreign bodies and blockages.

Hydraulic adjustment of the concave outlet.

In order to adjust the machine for different crop types, the concave outlet can be set to two different positions: wide for crops such as maize and beans, narrow for grain. The adjustment is made by actuating a valve near the cab door.

TUCANO 400-300

More safety and reliability. AUTO CROP FLOW.

Monitoring risks.

What can we do to make harvesting operations safer and more reliable? In extreme harvesting conditions, the operator needs to concentrate fully at all times in order to guarantee trouble-free operation. Often there are only a few days when grains can be harvested while at optimum quality – and it is precisely then that every minute of operation counts.

Early warning.

The speeds of the following components of the machine are monitored to provide early warning of critical peak loads:

  • APS threshing unit
  • ROTO PLUS rotor in the residual grain separation system
  • Engine

The engine speed is used as the reference value.

In the straw management area, the system detects if the straw chopper and straw blockage flap are stationary.

TUCANO 400-300

Matched to harvesting conditions.

The AUTO CROP FLOW function can be switched on and off in CEBIS. This allows the operator to choose whether to use the system or not. The sensitivity of the slip limits can be set at three levels to match the system optimally to the conditions in the field.

Operate at the performance limits.

The AUTO CROP FLOW function is intended to support the operator in operating the machine at its performance limits. It provides the necessary safety margin by automatically monitoring the components relevant to the crop flow and initiating the necessary measures.

TUCANO 400-300

Straw walker technology. TUCANO 450 / 440 / 430 / 420 / 340 / 320.

TUCANO 400-300

Cleanly separated over 4.40 metres length.

Grains this way, straw that way. The even flow of the straw on the 4.40 metre long, open-bottomed straw walker ensures that practically all the grains are separated from the straw. A separate returns pan sends the grains on their way to the preparation floor. Even large volumes of straw are moved with ease by the system.

Resistance is futile! The CLAAS intensive separation system.

Mounted above every straw walker are two guide-controlled agitator tines which actively loosen the straw from the top to ensure that it flows quickly in a thin layer. As a result, the remaining grains fall easily out of the straw, through the walker floor and onto the returns pan.

TUCANO 400-300

Work safely at the capacity limit with the throughput monitor.

It's easy to keep an eye on the separation and cleaning from the cab, as if through a "rear view mirror", with the CLAAS throughput monitor. It works with high-precision adjustments to adapt automatically to crops of different weights and display the results accurately.

Advantages for you:

  • In parallel viewing mode, you can fine-tune the combine faster by optimising the balance of the cleaning and residual grain separation functions
  • The throughput monitor indicates whether you are threshing at the best forward speed
  • You work safely at the performance limit of the combine
TUCANO 400-300

Cleaning – clean work pays better.

Clean team.

A clean crop in the grain tank and easy adjustment of the cleaning system are priorities for every operator. To make this a reality, we optimised the cleaning system of the entire TUCANO model series in 2016 in a process which involved the modification of the both the lower sieve and its oscillation angle. The result: clean grain, less material in the returns, easy adjustment.

Visual returns monitoring from the operator's seat.

The illuminated inspection window allows the operator to monitor the returns auger from the cab. In this way, users can quickly identify the combine settings which work best for them.

Rotary or turbine fans.

  • Depending on the model, there are six or four turbines or a rotary fan to ensure a consistent, uniformly distributed air flow pressure, even with variations in the sieve loading
  • Forced air flow control prevents crop mat formation
  • Reliable air flow even at low air speeds
  • Continuously adjustable from the cab

Preparation floor.

Pre-sorting of the grains (bottom) and chaff and broken straw (top) takes place on the preparation floor. The resulting reduction in the load on the upper sieve increases the cleaning capacity. All TUCANO models have a plastic preparation floor that can be pulled out towards the front.

TUCANO 400-300

AUTO SLOPE. Automatic fan control.

The easy way to make the most of any incline.

Hilly terrain calls for extra concentration on the part of the operator. This is precisely why the AUTO SLOPE function provides support for adjustment of the cleaning system. If the machine is operating uphill, the fan speed must be reduced in order to avoid grain losses from the sieve pan.

Conversely, the fan speed must be increased during downhill operation to maintain the crop flow in the cleaning system and to ensure that the grain is separated. AUTO SLOPE continuously adjusts the fan speed to the given conditions based on the fan speed preset by the operator.

How does AUTO SLOPE work?

When moving uphill:

  • Fan speed is reduced

When moving downhill:

  • Fan speed is increased

Advantages for you:

  • No wear – completely maintenance-free
  • The fan speed is adjusted automatically
  • Improved sieve pan performance through adjustment of air volume
  • Cleaning performance remains stable
  • Perfect interaction with 3D cleaning system in undulating terrain
  • Greater throughput and reduced losses on slopes
TUCANO 400-300

Electronic measurement of returns volume.

The fill level and composition of the returns enable conclusions to be drawn about the optimal machine settings to use. The TUCANO detects the total volume of the material in the returns.

  • Measurement is performed by a photo cell at the top end of the returns elevator
  • Returns volume and loss level are displayed immediately adjacent to each other in CEBIS
TUCANO 400-300

10,000 l. More space for top quality grain.

Impressive unloading rate.

The TUCANO model series is equipped with a turret auger and has an unloading rate of up to 105 l/s which allows the grain tank to be emptied in less than two minutes. Furthermore, the TUCANO has a large discharge height and reach. As a result, even large transport vehicles can be filled without difficulty. A corresponding range of grain tank unloading tubes for cutterbar widths up to 9.22 m is available.

Well-designed overall concept.

Many more well-thought-out details complete the overall grain tank design concept:

  • Easy grain sampling
  • High overhead discharge height
  • Ideal weight distribution
  • Good view into grain tank
  • Fast, direct unloading at up to 105 litres per second
  • Smooth surfaces in the grain tank facilitate complete emptying
TUCANO 400-300

Tidy work.

An automatic cover flap at the end of the grain tank unloading tube prevents grains still in the tube from leaking onto the ground. Every grain lands where it's meant to: in the transfer vehicle.

TUCANO 400-300

PROFI CAM – everything in view.

All TUCANO models can be equipped with a PROFI CAM at the end of the grain tank unloading tube. This camera position has been chosen precisely to allow up to three processes to be monitored simultaneously from the comfort of the cab on an additional colour display:

  • Grain tank unloading tube deployed: transfer process
  • Grain tank unloading tube retracted: distribution of chopped material
  • Grain tank unloading tube retracted: rear of machine during reversing or on-road operation

Up to four cameras can be connected to the system and feed their images to the colour monitor.

CEBIS rear camera.

The image from the rear camera fitted on the rear hood is fed straight to the CEBIS screen. As soon as the TUCANO moves backwards, the image from the camera is displayed automatically.

TUCANO 400-300

1 Adjustable cross cutter / 2 Rotor shaft / 3 Knives / 4 Bolt-on rasp bar / 5 Adjustable stationary knife

Chopped short and spread wide: your field is clear for the next harvest. Straw management.

Short chop, even distribution.

As it leaves the rotor or the straw walkers, the straw is finely chopped and spread evenly across the full working width. The debris from the sieve pan is fed to the heavy duty chaff spreader, which then distributes it evenly over the field. The spreading distance can be adjusted easily.

TUCANO 400-300

The TUCANO for rice harvesting.

Takes rice in its stride: the APS threshing unit.

As rice grains are delicate, the usual rasp bar threshing drum is replaced by a spike-toothed threshing drum to prevent them from being damaged during threshing. Additional toothed bars are bolted to the impeller (TUCANO 400) and to the feed drum (TUCANO 500). An APS threshing system is available ex factory for the following machines: TUCANO 570, 560, 450, 440, 430. The TUCANO 300 can also be upgraded for rice harvesting by means of a conversion kit.
