- More agile handling of the scalpers due to reduced weight, which prevents unscalped beets
- Perfect work quality, even at higher lifting speeds
- Driver can adjust the scalping level from “whole beet” to the “standard estimate scheme” (Göttinger Schätzrahmen) – for optimal harvesting results
- Prevents beets from being scalped too low
- Works with the established HOLMER KOS toppers
- No additional expense due to maintenance and costs
HOLMER lifter unit Simply harvest more.
Opitmal harvesting results for 6 to 12 rows: The automatic depth control system HOLMER EasyLift makes the HOLMER lifter units unique, the driver is harvesting, what is grown, with a reduced fuel consumption. High quality materials guarantee a minimal wear and the HOLMER EasyConnect offers a maximum safty and a perfect driver comfort with 9 or 12- row lifter units.
The new HOLMER HR lifter unit, which has been given the DLG award, offers automatic and independent depth control for each individual row, optimum lifting over the entire working width, reduced wear and fuel consumption. The recipe for success of the HR-lifter unit is its modular structure of the single row unit , which is automatically adjusting to every plant population.
The HR lifter is available in three variants:
- HR 45 – consistent 45 cm row spacing
- HR 50 – consistent 50 cm row spacing
- VHR – variable row spacing (45; 47.5; 48; 50 cm)
Its special benefits:
- Avoids breakage losses through individual and automatic setting of the lifting depth for each row
- Reduces unnecessary working depth and protects the machine against unnecessary wear
- Lifting depth can be adjusted at the edge of the field or in machine tracks

CleaningA tidy business.
Clean, undamaged beet = 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 enormous flow rates. Together with the new portal axle, the flow rate on the transfer web has been increased by 40 %.
- Incremental adjustments in transfer-web speed, turbine speed and elevator height can be made from the driver’s seat
- Equipped according to customer specifications: the 900-mm-wide transfer web can be divided (50, 60, 70 mm), as well as the segment grates in the turbines (spring tines or sliding grates) for varying harvesting conditions
- Transfer webs and turbines with independent drives are pressure-monitored and speed-regulated
- Fast-swap frame available for bar gates
- Automatic compensation of load peaks thanks to pressure-dependent increase of speed: adaptive cleaning for extremely gentle treatment of the beet and maximum operating safety at reduced speed levels
- Elevator with forged actuators and incrementally adjustable speed
- Cleaning shaft between the slat conveyor and the discharge elevator for additional cleaning
With the automatically controlled, switchable holding-tank scroll, the Terra Dos T4 makes for optimum distribution of the beet throughout the holding tank. In the Terra Dos T4-40, a free-ranging claw coupling in the tank auger protects the beet and reduces damage. Optimal weight distribution across all of the axles is constantly ensured using sensors in the holding tank, the hydraulic system, the chassis and the hillside compensator system. The extended discharge elevator allows beets to be unloaded to a trailer while driving, or wide heaps to be created easily. Automatic in-line transverse and longitudinal, allow the tank to be emptied in less than 50 seconds.
FramesA solid foundation.
The Terra Dos T4 frame concept:
Portal axle with a suspended support system on the front allows for maximum tyre size (IF 800/700 R38) and creates 40% higher transfer-web throughput
- Optimum stability on inclines and track-keeping on lateral slopes thanks to the low centre of gravity
- Extremely good stability even in difficult turning maneuvers on the slope thanks to the low center of gravity and the optimum location of the articulation frame

- Create databases for customer data, and transfer them to the machine using a USB stick
- Analyse all of the machine, driver and harvest data, operating overviews and individual assignment
- Monitor and send reminders about maintenance
- Track current lifting data online, together with the GSM module (optional)
The Terra Dos T4 is steered automatically during the lifting
process – via the leaf sensor and the share bodies, which
directly affect the rear axles and the front axle. The leaf topper and lifting unit adjust to the ground conditions independently from the vehicle. Thus the lifter also works very precisely even on extremely difficult, uneven ground, with minimal losses. The driver receives assistance, and is able to concentrate fully on the actual tasks, taking advantage of the yield-related parameters.
- Pivoting range of the articulation of over 60° for maximum maneuverability
- Extremely small (inside) turning circle of 6.50 m for the fastest turning times, even on confined headlands
- Automatic axle support and a low center of gravity of the vehicle guarantee outstanding slope stability even on very uneven ground
- The independently driven front axle allows automatic and manual adjustments to the preprogrammed response for the rear axles, for optimal traction in every position (from positive through zero down to negative)
- Reduced wear and waste along with maximum driving stability thanks to the ideal lead
The central or left-hand/right-hand offset position of the axles provides lifting flexibility. The following steering variants can be activated via the ergonomic joystick at the push of a button:
- Road travel: speeds of up to 40 km/h infinitely variable; the steering wheel only controls the front axle (up to 13 km/h, includes articulated steering)
- Four-wheel steer: the front and rear axles are operated via the steering wheel
- Turn steer: front and rear axles and articulation are controlled via the steering wheel
- Diagonal steer: the right or left wheels of the rear axle run between the tracks of the
- front-axle tyres, thus creating the best conditions for gentle soil preserving
- Combi steer (combination of turn steer and diagonal steer): the full articulation angle is also available in diagonal steer mode to ensure optimum preservation of the soil while driving to the beet heap or towards the next track
