Lightweight constructionSystematic light-weight approach.
Thanks to HOLMER’s engineering performance, the dead weight of the Terra Dos T4 models has been reduced significantly. Smooth transitions ensure greater stability despite needing less material. Clear and stable designs ensure stability and save weight.
Topper and HOLMER DynaCutPrecision at the peak of perfection.
The toppers of the Terra Dos T4 feature impressive, high-quality workmanship and can be adapted to individual lifting conditions perfectly – always providing the very best results.
KOS I: Integral topper that spreads the chopped leaves between the rows
- Allows side-by-side lifting
- The best starting situation for protective soilworking and sowing
KOS KO: Combines all of the functions of the integral topper with the proven leaf-spreading topper System
- Hydraulically operated and secured leaf screws and spreader tables allow large volumes of leaves and weeds - to be spread evenly across large areas
- Functions can be turned off from the driver’s seat during the lifting process – - for comfortable flexibility
- Topper shaft (600 mm diameter) with forged Tblades for long durability under optimal chopping
- This creates a low topper-shaft speed for low fuel consumption
- Topper units allow row spacing of either 45 or 50 cm, as well as variable row spacing between 45 and 50 cm

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. The stems remain after the topping process, which ensures height control without any losses from too-deep scalping.
- 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 unitsimply harvest more.
Optimal harvesting results for 6 to 12 rows:
The automatic depth control system HOLMER EasyLift makes the HOLMER lifter units unique, the driver harvests, what is grown, with reduced fuel consumption. High-quality materials guarantee minimum wear and the HOLMER EasyConnect offers maximum safety and 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 models:
- 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
- Lower power requirement thanks to integrated vibrating share operation in every row
- Integrated hydraulic, maintenance-free stone guard for each row

CleaningA tidy business.
Clean, undamaged beets mean 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 velocity: 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 enables 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 floors, allow the tank to be emptied in less than 50 seconds.
