The Leeb VN:

Well-known precision combined with flexibility

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.
With the Leeb VN we respond to the requirements “more clearance” and “flexible track”. Depending on vegetation and season the machine can flexibly adapt to the operational conditions and the challenges to provide our customers and their crops with utmost efficiency. There are many equipment versions for Leeb VN that make sure that it can perfectly adapt to any task.

Flexible track – flexible height

  • Clearance of up to 2.00 m and a track width of up to 3.00 m
  • Up to 62 cm wide tyres are possible
  • Optional: hydraulic height and width adjustment
  • Anti-slip control for optimum traction

Excellent manoeuvrability

  • Excellent manoeuvrability due to standard all-wheel steering
  • The central tube frame allows for a turning radius of only 3.5 m.

High-performance chassis

  • The hydraulically spring-loaded chassis guarantees a stable road and field handling at high speeds.

ComfortDriveFlex chassis

  • 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 6 000 liter and a constantly high driving stability with an optimum weight distribution of 50 : 50.
  • Each wheel of the standard chassis ComfortDriveFlex is individually suspended at the slide frame. The result is an excellent driving comfort.
  • The hydraulic individual wheel suspension adapts to the ground. The result is an extremely comfortable driving experience, and the boom control system 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 2.00 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 driving strategy can either be determined with the accelerator pedal or with the control lever. For changing you do not have to switch.

New motor

  • According to the current EU emission standard Tier 5
  • 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 1 500 rpm
  • 40 resp. 50 km/h on the read with 1 500 rpm
  • In field mode when the boom is folded in up to 25 km/h and up to 32 km/h when the boom is folded out at 1 300 rpm and 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 VL 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


  • Approx. 50 % incline
  • HighPowerGear shows its strength especially with low operational speed and extreme inclines.
  • When driving slowly below approx. 8 km/h or if the machine is on the verge of getting stuck, HighPowerGear provides the required power reserves to manage the most difficult situations.

Theodor Leeb

“Utmost clearance and flexible track widths, uncompromising with regard to driving comfort and stability – these were the parameters for the development of the Leeb VL. Due to the modular design of the chassis the farmer can decide which equipments suit him best. The result is a self-propelled sprayer that can be adapted individually to the requirements on site.”

Leeb VN Details

  • 5 000 or 6 000 litres tank made of PE or 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
  • Adaptable chassis with a clearance of 1.60 m in the standard version and up to 2.00 m with mechanical or hydraulic height adjustment
  • 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 200 bar.
  • A pump capacity of 320 liter allows for carrying out all tasks easily.
