The T Series comprises 4 models with 5 or 6 straw walkers. It replaces the three largest models in the WTS series. With a new threshing system, the T Series reportedly combines threshing capacity with preservation of straw quality, according to John Deere.
The ?T? Series comprises 4 models, with 5 or 6 straw walkers: the T550, T560, T660 and T670. The first digit indicates the number of straw walkers fitted to the machine (5 or 6) and the last two digits indicate the engine power level. These 4 models are also available in a Hillmaster version with slope compensation of up to 22%.
The ?T? Series combine harvesters are equipped with a John Deere PowerTech Plus engine with a displacement of 6,8 or 9 litres, rated from 290 to 400 ch.
Compared with the WTS models that they partly replace, the threshing components have been redesigned on the T Series combines. With the exception of the single cylinder, identical to that of the WTS Series (660 mm in diameter and heavy for high inertia), the following components are different. The cylinder is followed by a reverse-rotation drum that guides the crop from the cylinder to the separator not from underneath but from above, in order to eliminate sharp angles. After this drum, there is a tangential separator 660 mm in diameter with a concave separator offering threshing capacity, then a straw beater guiding the crop toward the straw walkers. This straw beater also has a separation element.
Thanks to this new system, the threshing path has been lengthened to 2,01 m without the reverse-rotation drum and 3,03 metres with it. The crop thus travels a long distance, which improves separation.
This new series retains the Quadra Flow cleaning shoe, a characteristic of the 9000i WTS and CTS Series machines.
The T models can be fitted with PremiumFlow cutting platforms, whose feed pan has been resized to accommodate belts. These headers are said to optimise crop flow between the cutter bar and the conveyor in all harvesting conditions. They can be equipped with mechanically driven side knives for harvesting rapeseed.
John Deere is also introducing precision farming solutions for this new series of combine harvesters with its ?i? package. This kit includes the AutoTrac automatic guidance system (accuracy level from 0 to 30 cm), the ?HarvestSmart? automatic speed control to optimise productivity, and the Harvest Doc software, which continuously measures the yield and moisture content of the crop.
