Carrot technology - Trailed harvester | T-255DF

Two rows, trailed, with overloading elevator

The carrot harvester, type T-255DF, is a trailed two row toplifter, with cart elevator. The machine can be used for an effective harvest of carrots, parsnips and other root crops. The machine is characterised by its long top lifter belts with a length of 550". This gives the machine more space for root-cleaners so that adhering soil can be cleaned off in a very effective way. In addition, the longer top lifter belts create more space for larger tyres, which increases ground protection and facilitates use in wet harvesting conditions. The machine is gentle to the crop, so that the harvested carrots can also be used for storage. A share loosens the soil below the root. The rotating torpedoes raise the haulm/carrot tops so that it can be pulled out by the clamping belt. A root-cleaner removes adhering soil. A cutting unit removes the haulm/carrot tops at the base so that it can be ejected behind the machine. The carrots are conveyed directly via cross conveyor onto the cart elevator. Thanks to the direct crop flow, this variant is particularly gentle on the crop.

Benefits

• High level of crop protection thanks to the digging system with a top lifter belt and a direct, straight crop flow in the machine. This reduces losses and increases the proportion of marketable goods.
• High capacity due to multi-row intake.
• A long top-lifting assy provide space for more root-cleaners, which can be used for efficient soil cleaning.
• Large tyres for low soil compaction and improved tractability in wet conditions.
• The wide cross conveyor and the wide cart elevator allow reduced conveying speeds with lower mechanical impact on the crop. Alternatively, a higher capacity can be achieved with the same crop protection.
• Overload protection devices fitted as standard in the top-lifting assy prevent major damage to the intake, thus reducing repair times and costs and increasing the operational reliability and availability of the machine.
• Shear bolts for the torpedoes reduce the risk of the belt arm lowering/diving into the ground.
• Shear bolts in the front part of the intake prevent the top-lifting assy from bending in the event that the intake "dives" into the ground or hits a large object in the field.
• A spring prevents the two halves of the top-lifting assy from bending open when a stone is conveyed upwards.
• The first top lifter rollers arranged next to each other allow the clamping force to be adjusted in the foremost area. Compared to offset mounted top lifter rollers, these can achieve a higher clamping force if required in order to reduce losses or increase the harvesting speed.
• The standard quick-release system for the following offset mounted top lifter rollers enables an easy adjustment of the clamping force or simple belt replacement to minimise machine maintenance costs.
• The bearing of the top lifter rollers with rubber spring elements is maintenance-free and therefore reduces maintenance costs and ensures a constant clamping force.
• Cutting unit with special sealing for long service life.
• Precise synchronisation of the cutting unit by a gear transmission for an accurate removal of haulm/carrot tops and a long service life.
• Standard rubber covers on the bars of the main web reduce damage and increase the proportion of marketable goods.
