The Leeb PT:
SETS STANDARDS IN PLANT PROTECTION TECHNOLOGY
To achieve more in a shorter time with less machines – due to this strategy companies today manage to work successfully and to remain competitive. As a manufacturer of plant production technology it is our objective to support the farmers with efficient and precise technology.
Our engineers work hard to find the appropriate solutions for the special requirements on application technology in the plant protection sector and to design an efficient and flexible machine for a wide range of use.
The result is a new generation of the Leeb PT that combines driving comfort, performance and maximum application efficiency. The new PT leaves nothing to be desired and offer even more possibilities than before: more clearance, more driving comfort, more climbing power, a wider selection with regard to the working width. In short: The PT offers almost infinite variability for highest requirements on technology and on driving experience.
Large tyres – optimised ground pressure
- Four equally sized tyres with a diameter of up to 2.18 m and a width of up to 71 cm guarantee maximum contact area with an adapted air pressure.
- Optimum traction even in difficult conditions
- Traction control system (TCS) for optimum traction control
- Excellent manoeuvrability due to standard all-wheel steering
- The central tube frame allows for a turning radius of only 3 m.
- No greasing spots at the whole basic machine as only maintenance-free bearing are used.
- The front cabin on the central tube frame and the boom in parallelogramm suspension guarantee an optimum weight distribution – on the road and in the field.
- The arrangement allows for enough space for a tank capacity of up to 8 000 liter and a constantly high driving stability with an optimum weight distribution of 50 : 50.
- At the standard chassis ComfortDrive every tyre is mounted individually at a double control arm suspension. Thus, the driving comfort is similar to the one of a car.
- The hydropneumatic single wheel suspension adapts automatically to the ground in a levelling way. This guarantees an extremely comfortable driving experience and the BoomControl is supported positively.
- Due to the smooth driving characteristics, the boom control system easily manages to keep the balance even at higher speeds.
- The flexible clearance of up to 1.30 m (depending on the tyres) allows for protecting the plants while working even in high populations.
Automotive drive control
- Automotive drive control with standard equipment:
- Maximum load control
- Overspeed control
- Driving with reduced motor speed
- Speed control
- Headland management
- The hardness of the suspension set-up is automatically adapted when changing from road to field mode.
- The driving strategy can either be determined with the accelerator pedal or with the control lever. For changing you do not have to switch.
- Stage V according to current EU exhaust emission standard
- 6.7 liter six-cylinder FPT engine
- Turbo motor with charge air cooling
- The Common-Rail system convinces with an impressive performance of max. 230 kW / 310 hp.
- Maximum torque of 1 160 Nm as of 1 400 rpm
- 40 resp. 50 km/h on the read with 1 700 rpm
- In field mode up to 25 km/h with a engine rotation speed of 1 300 rpm and a load-dependent adaption
PowerGear wheels gears with intelligent drive
- Infinitely variable from 0 – 50 km/h
- The efficiency factor in the main working range has been specially optimised for the use in the plant protection sector
- Intelligent all-wheel drive: dynamically distributed drive torque – powerful and efficient
- Selective traction control for every tyre
- Due to larger wheel motors at the rear axle and the corresponding higher driving power, the PT easily manages any terrain.
- Two gear box versions, depending on the field of application:
- PowerGear with powerful drive even at steep slopes
- HighPowerGear for more torque at the wheel and highest requirements in the field
Leeb PT details
- 6 000 liter tank made of polyethylene or 8 000 liter tank made of stainless steel
- Optimised weight distribution due to the arrangement at the central tube frame with individual wheel suspension, front cabin and parallelogram suspension of the boom
- Automatic level regulation of the chassis with a clearance of up to 1.30 m
- Automotive drive control
- Optimised hose laying reduces hose lengths to a minimum
- Boom suspension has been designed as a parallelogram suspension – spring-loaded and damped hydraulically.
- Soft and smooth boom position even in hilly terrain and at a high operational speed
- The geometry of the parallelogram has been designed in such a way that the boom is kept close to the axle. The suspension is extremely warp resistant and thus ideal for the automatic boom control systems Leeb BoomControl.
- Nozzle protection against mechanical damage of the nozzles and wind protection when a spraying fan develops
High-efficiency hydraulic system
- The core of the Load Sensing system is a powerful axial piston pump with an operating pressure of 210 bar.
- A pump capacity of 320 liter allows for carrying out all tasks easily.
Comfort, safety and functionality
- Comfort and functionality are important characteristics of the new HORSCH Leeb PT: A lot of features like the individual wheel suspension, seat and armrest suspension, driving dynamics and the large cabin interior guarantee a new dimension of driving experience.
- The spacious cabin offers an optimum view on the machine and the population and the inside leaves nothing to be desired.
- A premium comfort seat: active vibration damping, seat heating and seat ventilation guarantee the driver a luxury driving experience.
- Due to the excellent insulation, dust and noise remain outside.
- A powerful automatic air-conditioning with heating guarantees a comfortable indoor climate.
- Cabin filter Cat. IV to protect the user from dust, aerosols and steam
- Heatable power mirrors
- The height and the inclination of the steering column can be adjusted.
- The display for the vehicle functions and the speedometer are located at the A column.
- The ISOBUS terminal for the spraying function is integrated in the armrest.
- The ErgoControl armrest can be adjusted in height and in length and is equipped with integrated ergonomic control elements and a joystick.
- Passenger seat as well as numerous compartments and cooling compartment
- Radio with bluetooth interface
Optimum working conditions at night
- Four working lights are mounted on the cabin roof as a standard.
- Four working lights incl. TrackFinder are available additionally.
There are sufficient storage compartment everywhere on and in the cabin of the PT
- Dust- and splash-proof boxes are integrated at the control centre and at the diesel tank.
- A storage compartment for for example tools is located below the cabin.
