Deutz-Fahr 7 TTV Series

Transmission

PREVIOUSLY UNIMAGINABLE EFFICIENCY

Based on the same layout already proposed in the T7780 (already tried and true on the Series 8) and T7560 versions, the new continuously variable transmissions raise the bar in the category in terms of efficiency and reliability. A perfect combination of planetary mechanical components with a new and highly efficient high-pressure hydrostatic unit guarantees a consistently smooth and even power flow, without jerks and with maximum performance, not to mention reduced fuel consumption and lower heat dissipation. The new powertrain, which is assembled in Germany at the Deutz-Fahr Land in Lauingen, features an exceptionally high-performance transmission, giving the 7250TTV unprecedented acceleration and smoothness, as well as a significant increase in the torque transferred to the wheels (+ 35% for the 7250 TTV model and + 50% for the 7250 TTV HD). The new TTV transmissions also allow these tractors to attain a maximum road speed of 60 km/h at an engine speed of just 1800 rpm, while 40 km/h is available at an incredibly low engine speed of around 1200 rpm. The Powershuttle, by now fully affirmed, is adjustable to 5 sensitivity levels in order to adapt perfectly to every specific need.

PTO

FOR MAXIMUM EFFICIENCY AT ALL TIMES

The profitability that can be obtained from a tractor is strictly connected to both operational capacity and operating affordability. The new 7 Series stands out precisely for these characteristics: the engine offers outstanding performance, even at low rpm, whereas the PTO, which has electro-hydraulic activation that can be modulated through iMonitor, comes standard with 3 speeds at the rear (540ECO/1000/1000ECO) and up to two at the front (1000 or 1000ECO). With the DualSpeed option, those speeds can be changed from the cab in the InfoCentrePro. This allows maximum operating efficiency at all times and means, that it is possible to operate frequently with the engine at low rpm, significantly reducing fuel consumption, wear of the moving parts, and noise in the cab, which also extends the routine service intervals. The interchangeable type rear PTO shaft makes it quick and easy to swap out, facilitating connection with any equipment and also reducing costs in the event of damage. The PTO operating modes can be managed both from the armrest in the cab and from either rear mudguard. For a comfortable coupling of the implement the rear PTO features now also a neutral position.

Hydraulic system

BEST IN CLASS PERFORMANCE

The hydraulic system of the new 7 Series features premium solutions usually seen only on larger and more costly tractors. The hydraulic circuit is independent of the transmission lubrication circuit, whereas the pump, available alternatively with 3 different flow rates (120, 160, or 210 l/min), is a Load Sensing type in order to prevent using power when no pressurized oil flow is needed. Up to 90 liters of oil is on tap for hydraulically operated implements, while these tractors can be equipped with up to 5 hydraulic distributors at the rear and two at the front (in addition to the front lift distributor, if installed). All the distributors are electronically controlled and they can be programmed and controlled proportionally; the Power Beyond connection is now also available with the new flat fittings. The potent rear lift has a capacity of 10,000 kg (11,100 for the HD version). A new feature on the new 7 series is the available transport position for the lower links as well as the hydraulic side stabilizers. A lift is obviously also available at the front, with force control and an incredible 5,450 kg of maximum capacity. All of this is rounded out with an intuitive interface for easy connection of compatible ISOBUS equipment.

Brakes

FOR SUPERLATIVE SAFETY

In order to be productive, the operator must have maximum control of the vehicle, both in the field and on the road, whether at high speeds or on bumpy terrain and with the heaviest equipment. While working on the new 7 Series, in any conditions, you can feel the machinery's high level of safety. The new heavy-duty front axle and the braking system on the 7 Series are also unique in this tractor class. The intelligent and adaptive suspension system gives the new 7 Series maximum stability – both during heavy towing operations and when driving large loads. The innovative suspension concept stabilizes the tractor during all transport operations and boosts driving safety. In order to ensure better handling on uneven ground, the dampers are mounted on the front side of the axle. The 7 Series is the only standard tractor that can be fitted with high-performance dry disc brakes on the front axle. The additional booster brake system ensures maximum braking performance with light pedal pressure. No other standard tractor can offer a heavy-duty front axle, dry disc brakes in combination with the booster brake system, and more safety, especially at higher speeds. For increased safety, the new 7 series is equipped with an aTBM system, which increases the braking performance of the trailers while braking. And if ordered with hydraulic trailer brakes, the new 7 series is equipped with a dual-mode valve.

Cab

UNPRECEDENTED COMFORT

The revamped MaxiVision 2 Cab raises the bar in its class, thanks to the air suspension, high-quality materials, great reliability, and attentive control design. A multitude of features can be controlled using the ergonomic joystick located on the armrest: from speed selection to driving direction, to the combination of the ComfortTip actions, to front and rear lift controls. It is an intuitive and immediate system that you don't even have to move your hand to operate. The cab separated from the engine compartment limits the transmission of heat, vibrations, and noise, increasing comfort to unprecedented levels, so much that the internal noise is contained to 69 dB(A) with the engine at a maximum rotation speed. Visibility is outstanding in all directions, even at night, thanks to its powerful LED lights. InfoCenter-Pro provides information that is always clear and accurate and the mini MMI allows for easy definition of all the tractor settings. The openable roof is available in opaque and shading versions, transparent with anti-U.V. treatment, or transparent in high-density polycarbonate, with internationally certified FOPS protection.
