PRACTICAL TEST: With the Trion (profi HS 2021), Claas is targeting mid-sized growers and contractors. We tested the single-rotor Trion 730 through the tricky 2023 harvest.
Getting straight to the point, in terms of technology and comfort, the Trion can offer almost the same features as the latest Lexion — it is just a bit
smaller in terms of the size of the threshing technology and all the crop-engaging bits that go with it. The Trion comes with the familiar APS hybrid threshing unit, which was taken from the previous Lexion, with a 450mm pre accelerator and 600mm drum, both of which measure 1.42m or 1.70m depending on what comes next in the straw and grain separating phase.
The 1.70m wide machines have six walkers, while the slimmer 1.42m version has a bit more variety: five walkers or a hybrid with single or double rotors depending on model. For instance, the range-topping 750 has a pair of 445mm diameter rotors, whereas our test machine, a Trion 730, has a single 570mm rotor.
Vario table recommended
Claas has a huge choice of headers for these machines. With cereals and oilseed rape on the list of crops to harvest, our test Trion was supplied with the extendable Vario cutterbar. On its right, it has a slim hydraulic reel drive with gears instead of a chain.
The Vario’s mechanical-drive side knives even manage without oil, making them around a third lighter than those with hydraulic drive, and they come with a 50% higher cutting force thanks to the ratchet clutch, according to Claas.
