TOPPER BE PRECISE.
The leaf stalk has approximately 5-7 cm (2-2.75 in) – depending on the area of application and setting – which the topper of the Terra Dos T4 leaves on the sugar beet. The remaining leaves are cut off with the scalper.
The automatic depth control of HOLMER EasyLift is also extended on the topper. This is automatically adjusted in height – leaving only as many inches of leaf stalk that the operator has previously set; elaborate adjustments are no longer needed. When the height of the roller bed is changed, the topper is readjusted automatically. The topper height is adjusted hydraulically and without the support wheels.
The HOLMER integral topper HS I and the HOLMER combi-topper HS KO provide solutions for various types of use when dealing with leaf mass.
- Topper shaft with 600 mm (23.6 in) diameter and forged T-flails – for optimum shredding with minimum wear
- Low topper speed – for low fuel consumption
- Fully bolted steel plate construction – for easy maintenance
- Reduced vibration in the field and on the road – for shock reduction
The HOLMER integral topper, which places the shredded leaf between the rows of beets.
- Track-to-track lifting possible – for a clearer overview
- Nutrients are retained – as an organic fertilizer
- Uniform soil cover – as the best starting point for conservative soil cultivation
- Gentlest topper options – to preserve the soil
The HOLMER combi-topper, which either distributes the shredded leaf between rows of beets or spreads them over a previously planted area by means of a leaf spreader in the case of strong weed growth.
- Functions can be switched from the operator‘s seat during the lifting processes – for comfort and flexibility
- Hydraulically powered auger and leaf spreader – for uniform spreading of large volumes of leaf and weeds
- Nutrients are retained on the field – as an organic fertilizer
- Leaf-harvesting possible with the HOLMER foliage belt – for further use of the biomass
HOLMER has perfected the defoliating cutting technique with the DynaCut. Its new geometry allows the DynaCut to harvest the entire beet without any leaves left attached.
Because the beet crowns are your yield.
- More agile handling of the scalpers due to reduced weight – ensuring reliable scalping of beets even at high speeds.
- Adjustable crown level at the push of a button – for optimum lifting results
- Does not scalp beets that have been cut too low by the topper – for your yield
- New and thinner blade grinding – for a much longer sharp edge
- Easy maintenance and low service costs – for your profit
LIFTER UNIT GET THE BEST.
As early as 2009, the HR lifting unit had been awarded a silver medal by the DLG. At that time, the single row depth adjustment of each row unit was revolutionary. Since then, HOLMER has steadily worked on further developing the lifting unit. With HOLMER EasyLift, the single row depth control has been working automatically since 2015 – for six, eight, nine or twelve rows.
The recipe for success of the HR lifter unit is its modular structure of the single row unit, which automatically adapt to each sugar beet crop.
Because we invented the single-row depth adjustment.
- Best view into the lifting unit from the driver’s seat – ideal for monitoring the lifting quality
- Active and oscillating lifting movement of the shares – for gentle beet loosening and thus less root breakage
- Pulled arrangement of the share bodies – for low tractive force requirements
- Lifting depth per share visible and adjustable in the cabin including warnings – for easy learning
- 70 mm (2.75” in) lateral movement of all share bodies – for flexible row adjustment
- Integrated hydraulic, maintenance-free stone guard for each row – for best operational security
- Shares, paddle shaft, and roller speed can be adjusted independently of each other – for perfect lifting under all conditions
- 7 lifting and cleaning rollers – for more cleaning areas
- Incremental speeds from only 300-600 rpm – for gentle conveying
- Lifting rollers with 22-30 mm (0.87-1.18 in) high spiral winding patterns – for maximum conveying capacity
- Automatic reversing while lifting – for removing stones
- Option: Various lifting roller diameters for 2nd and 4th lifting rollers – for minimizing losses with special crops and small beets
- Feeler wheels with 750-800 mm (29.5-31.5 in) diameter – for complete lifting unit height control
The EasyLift that was developed by HOLMER automatically takes over the depth control of the individual share bodies so that each beet can be lifted at the optimum depth at all times. For this purpose, the on-board computer calculates the maximum heights of the beet from position measurements and automatically adjusts the working depth of the share bodies. Thanks to this automation, the full potential of the HR lifter can be reliably utilized with the same constant power.
For ease of operation.
- No excessively low working depth – to avoid breakage losses and damage to the beet body
- No unnecessarily deep lifting – for less wear and lower fuel consumption; since for every 0.5 in too deep means about 50 ton / acre of unnecessary earth movement
- Automatic slope system – for optimum adaptation of the HR lifter on slopes
- Optimum relief for the operator through up to 2,600 regulations per ha (1052 regulations per acre) – for working comfort
- Perfect lifting results even in the case of yield fluctuations, different beet forms due to different varieties, unevenness on the edge of the field or furrows, sprayer tracks, patchy populations, as well as soil conditions depending on the weather and location - for your profit
HOLMER tested a new type of share during the 2018 beet harvest:
The HOLMER DuraShare has a working life up to twice as long as that of a conventional lifting share. This makes an important contribution to consistently high lifting quality, low wear costs, and minimum downtime.
After the convincing practical test, the DuraShare is available for sugar beet harvest 2019.
It lasts and lasts and lasts:
- Forged share from a single cast, so that material is used where it is needed – for more stability and less wear
- Small carbide plates soldered onto the lower edge as wear protection – for the longest durability
- Slipstream edge by the carbide plates reduces contact with soil and stones – for lowest material wear
- Backward compatibility with previous Terra Dos models – for maximum flexibility
- Design protection – to distinguish yourself from others
Be it 8, 9 or 12 rows. The wide HR lifting units have been tried and tested for many years, as the world recordholder in beet-lifting with the HR 12 lifting unit shows. The additional rows increase the surface area of the Terra Dos T4 significantly. This helps to reduce the number of non-operating times and save crossings.
Because more shares simply lift more.
- Diagonal steer already possible with the first lifting – to prevent damaging soil compaction
- Modular design – for straight-forward maintenance
- The basis for fast, efficient harvesting – with substantial fuel savings
- Fewer passes in the field – for active soil protection
- High lifting speeds – for more area capacity
- Rapid loading onto loading vehicles of up to 4.00 m (13.12 ft) during lifting – for a coherent logistics concept
- Transport trailer with suspension for road transport
- Wider tires possible on the front axle – for optimum weight support
- Integral topper HS I can be hydraulically tilted by 180° – for easy transport
The fast-coupling frame developed and patented by HOLMER, HOLMER EasyConnect, expands the previous mechanical systems with an automatically coupled hydraulic and electrical supply interface.
Coupling can be very straight-forward.
- Coupling in a one-man process in under 1 min – for the shortest setup times
- Convenient coupling and uncoupling from operator‘s seat (mechanical, hydraulic and electric) – for the safety of man and machine
- No manual coupling of heavy and rigid elements required – for perfect operating comfort
- Automatic recognition of HR 8/HR 9/HR 12 – for the straightforward use of different lifting units
CLEANING STAY CLEAN.
Clean, undamaged beet means more money. The Terra Dos T4 provides the perfect basis for this. All of the cleaning and transport units, such as the transfer web, turbines and elevator are optimally adjusted for maximum flow rates and perfect cleaning. Together with the new portal axle and the single axle drive concept, the flow rate on the transfer web has been increased by 40 % compared to the previous model.
Because only clean beets are your profit.
- Incremental adjustments in transfer-web speed, turbine speed and elevator height can be made from the driver’s seat – for optimum cleaning
- The 900-mm (35.43 in)-wide transfer web comes in different pitches (50, 60, 70 mm), as well as the segment grates in the turbines (spring tines or sliding grates) for varying harvesting conditions
- Transfer web and elevator belt made of most modern, ultraflexible components – for longer durability
- Forged guide rails, turbine tines and carriers on the elevator belt – for less wear and less weight
- Strengthened feeder bars on the elevator – for maximum stability with big harvest yields
- Optional: Quick-change frame for turbine spring tines – for short setup times
- 1000 mm (39.4 in)-wide elevator with incrementally variable speed – for quickly transporting the beets to the tank
On the headland or at the end of a row there are often few sugar beet in the cleaning system. This increases the contact of each individual beet with the machine components. A higher speed of cleaning, as it is useful in the row for transporting high harvest quantities, leads to increased damage and broken beets. To avoid this, the speed of the HOLMER cleaning system adjusts automatically to pressure and also matches the driving speed of the Terra Dos T4.
One beet cleans the other:
- Automatic adaptive cleaning plus – for optimum driver relief
- Independent drives of transfer webs and turbines, pressure-monitored and speed-controlled – for reliably high cleaning and conveying performance
- Adjustment of transfer belt, turbines and elevator additionally dependent on driving speed –for maximum beet protection when there are few beets in the cleaning system
- Adjustable settings for the response of the automatic system – for optimum adaptation to different harvesting yields
TANK BE SINCERE.
With the automatically controlled, switchable holding-tank scroll, the beets are optimally distributed in the tank and the fill level is monitored by 2 ultrasonic sensors. This constantly ensures optimal weight distribution and maximum traction.
In the Terra Dos T4-40, the tank auger is also divided. As soon as the hopper is completely filled at the back, the rear part of the auger turns off so as to not damage the beets.
The extended discharge elevator allows beets to be easily unloaded to a trailer while driving, or wide piles to be created easily. Automatic in-line transverse and longitudinal floor chains allow for fast emptying of the tank.
Transfer beets correctly.
- Tank volume of 30 m³ (39.25 cubic yards ) or 45 m³ (58.85 cubic yards) – ideally suited for every field size
- 2 ultrasonic sensors – for estimating yields and determining the fill level
- Terra Dos T4-40. 2-split hopper auger – for optimum filling

CHASSIS CONCEPT BE STABLE.
The Terra Dos T4 is consistently manufactured in a lightweight and modular design.
A straight central tube frame made of high-strength S700 steel – from one piece – forms the reliable, weight-optimized base frame. The front part of the basic vehicle is connected to the main frame by means of a 60° articulated joint.
This is the basis for maneuverability in any situation and optimum weight distribution.
Simply intelligent driving.
- Swivel range of the bend of more than 60° – for maximum maneuverability
- Turning circle (inner) of only 6.50 m (21.32 ft) – for shortest non-productive times
- Front portal axle with slope support system – for ideal stability in any position
With Terra Dos T4-40.
- Fixed to the middle axis that is connected to the frame – for high machine stability
- Rear axle oscillating – for maximum terrain adjustment
- Rear axle hydraulically sprung including hydraulic load balancing – for optimum driving comfort
- Axle load regulation depending on the tank filling level – for optimum weight distribution
Driving comfort, track accuracy and stability on slopes were priority development targets for the Terra Dos T4. Axles that are directly powered hydraulically with highly efficient inclined axle motors guarantee the most efficient power transmission and maximum performance.
In combination with the slope sensor, the innovative propulsion concept of the Terra Dos T4 automatically selects the ideal torque differential between axles (lead) that is needed in every situation.
Use power where it is needed.
- Hydraulically powered axles with inclined axle motors – for the greatest efficiency
- Automatic adjustment of the front axle drive torque in relation to the rear axle speed (lead) – to avoid the bulldozing effect and for optimum traction

STEERING HANG ON.
The offset track driving ensures that it is virtually impossible to roll over the same track twice. With the Terra Dos T4-30, each wheel has its own track. This consistently prevents soil damage from compaction. Given the large contact surfaces of the tires in the diagonal steer, load and traction force are transmitted over a wide surface area – with optimal slip values at the same time. This is how real soil preservation works.
The Terra Dos T4 steering modes.
- All-wheel steering – for driving without articulated steering
- Turn steering including articulation – for maximum maneuverability
- Diagonal steer left/right with 2 selectable steps – for rolling over wide areas and for stable driving behavior also on slopes
- Combi-drive (combined turn and diagonal steer) – for the best soil protection during turning maneuvers
- Four-wheel steer – for lifting with 6-row lifting units
- Manual steering – for independent steering of the rear axle by joystick
- Road travel (only the front axle is controlled by the steering wheel) – for incremental travel speeds of up to 40 km/h (25 mph), (also up to 13 km/h (8 mph) with articulated steering)
ILLUMINATION KEEP AN OVERVIEW.
The illumination concept of the Terra Dos T4 turns night into day. This also ensures optimal visibility during work at night. The operating range of the machine is illuminated up to 100% by max. 28 LED headlights. This guarantees maximum safety during harvesting, unloading, and turning – especially at night.

The first headland management system for self-propelled harvesters. For the first time, SmartTurn combines the mechanical row steering system and the headland management system TerraControl on the beet lifter with GPS-controlled headland turning, as is known from tractors. This makes automatic turning at the front end possible for the first time – including lifting and re-insertion of the lifting unit, as well as the necessary steering maneuvers.
The joint development of REICHHARDT and HOLMER expands the Terra Dos T4 with a modern, automatic steering and smart-farming function to optimize beet harvesting and soil protection. The system has been awarded a DLG silver medal.
1. An acoustic signal indicates the optimum time for the turning process. The driver activates SmartTurn. The Terra Dos T4 automatically stops lifting when the predetermined limit is reached and it raises the lifting unit at the ideal point.
2. At the same time, GPS steering takes over the turning process, using an ideal turning path. The system automatically checks the correct, next track.
3. There, SmartTurn automatically reinstates the lifting unit at the ideal point. The proven row sensor steering system then takes over control of the machine in the track. REICHHARDT SMART CONTROL records all data which is later available for documentation and evaluation.
The clever way to turn.
- Automatic control of the vehicle via GPS or row sensor – so that the driver can concentrate entirely on monitoring the lifting quality.
- Always the best and shortest tracks on the headland without unnecessary maneuvering – for optimum soil protection
- Automatic lifting and fitting of the lifting unit at the optimum time – for reduced wear and fuel consumption
- Quicker turning on the headland – for the shortest non-productive times
- Automatic insertion in the right row – to relieve the driver and to avoid loss of harvest
