TT270 |
The TT270’s electronic system automatically determines the hydraulic
pressure needed to raise the implements. The driver can enter the desired level of weight transfer as a percentage, and the hydraulic system sets the necessary pressure. Thanks to this simplification the driver can concentrate to a greater extent on the actual work.
Two power take-off speeds are available, at both front and rear. Engagement is electrohydraulic and can be operated under load. The lifting mechanisms can
also be operated from outside the vehicle. |

 |
| Engine |
Detroit Diesel VM D754 TE2, 3000 cm³,
4-cylinder with turbocharger, 4-stroke, direct
injection, water-cooled, 70 kW (95 hp) at 2600 rpm to ECE R24, max. torque 335 Nm at 1300 rpm. |
| Electrical System |
12 V, 90 A alternator, 88 Ah high-perfor-mance cold-start battery, automatic pre-heat system. |
| Transmission |
Continuously variable hydrostatic with adjusting
pump, adjusting motor and 2-speed output gearbox. The vehicle-drive control system can be switched on and off. |
| Speeds |
Forward and reverse: off-road 0–9.5/0–20 km/h, road 0–16/0–40 km/h. |
| Power Take-Off |
Standard 13⁄8" profile, 6 splines, dry single-plate clutch operated electrohydraulically, can be engaged and disengaged under load. Speeds: front 550 and 1090 rpm, rear 580 and 760 rpm, pre-selectable separately front and rear. Direction of rotation, clockwise. |
| Axle Drive |
Permanent 4-wheel drive with Torsen inter-axle differential and fully lockable differentials
in the front and rear axle, operated electrohydraulically. |
| Steering |
Hydrostatic 4-wheel steering, switchable to front-wheel steering, rear-wheel steering
or quasi-crabsteering by push-button control, change of steering mode at will by automatic detection and synchronisation of wheel position via inductive sensors. Turning radius with all-wheel steering:
3.3 m (lock: 40°).
With double tyres, turning radius 4.15 m (lock limit: 30°). |
| Tyres |
All Ground 425/55 R17 radial tyres. Other tyres on request. |
| Brakes |
Hydraulic twin-circuit servo footbrake operating
on all wheels; in addition, hydraulic driving brake, handbrake and single-wheel brake on rear wheels. |
| Cab |
Dust-proof all-round view comfort cab, vibration
and noise-damping, with safety frame (tested to 79/622/EEC), front windscreen, sidescreens and glass door, curved, openable
rear screen. All screens tinted. Integrated
automatic air-conditioning system. Ergonomic seat with multiple adjustments, plus lap seat belt. |
| Operation |
A total of 20 functions can be controlled via the drive lever. Using the keypad to the right of the driver, additional hydraulic-system functions and also the heating and air-conditioning system can be controlled, and operating sequences such as coupling up front and rear lifting equipment can be programmed. All information about the operating state and important settings are shown via a display or with indicator lights. |
