The Leeb LT:

Engineering for professionals

The basis

  • Solidly designed frame made of quality steel
  • Optional: air-suspended axle with level compensation
  • Solid drawbar connection for large clearance, top or bottom connection, depending on the vertical load

Steering axle – less tramline damage (optional)

  • Steering axle for stable positioning of the boom with high stability and exact tracking to avoid tramline damage
  • Optimal, even in uneven terrain
  • Large steering angle due to a taper-cut frame design

Large tyres – less ground pressure

  • Wheels with diameter of up to 2.05 m
  • Maximum ground contact area with perfectly adapted air pressure
  • Adapted Tyre Pressure Control – automatic tyre pressure regulation that is completely integrated in the software

Extremely low centre of gravity

  • Tank shape is optimised with regard to the surging force

Taking care of the crop

  • Smooth machine underbody
  • No edges and corners on the underside of the machine
  • Hydraulically foldable and fully covered support leg

Modern plastic tank

  • Conical geometries for low surge forces
  • 500 litre fresh water tank: enough water for a complete inside cleaning as only very little residual quantities remain in the system.
  • Large radii, absolutely smooth surfaces and no back tapers for easy cleaning.
  • Deep sump area for complete discharge and minimum residual quantities even on slopes.

 

Three equipment versions

Eco

  • Manual operation for the suction and pressure side
  • Piston diaphragm pump (400 l/min) driven by pto-shaft
  • Hydraulic agitator

CCS

  • Manual operation for the suction and pressure side
  • Additional piston diaphragm pump for the continuous inside cleaning system CCS
  • Continuous inside cleaning can be operated in the cabin
  • Oil-driven (Load Sensing) centrifugal pump (600 l/min)
  • Hydraulic agitator

CCS Pro

  • Electronic operation on pressure and suction side for complete control from the cabin
  • Additional piston diaphragm pump for the continuous inside cleaning system CCS with automatic washing programs, e. g. intensive washing program, boom rinsing
  • Centrifugal pump driven via oil (Load Sensing) (600 l/min)
  • External control terminal
  • Hydraulic agitator, is controlled electronically via terminal and external control unit. Automatic switch-off if the residual quantity in the mixture tank falls below 150 liter.

Blog post - Leeb PT: More nozzles, more options!?

Theodor Leeb

“When we developed the Leeb LT, the focus was on highest precison in plant protection combined with utmost efficiency.“

Leeb LT details

  • Tank capacity: 4 000, 5 000 and 6 000 litre
  • Top or bottom linkage selectable
  • Low gravity centre of the spraying tank
  • Tank made of polyethylene (PE)
  • Optimised tank shape for transport and cleaning
  • Optimised hose laying reduces hose lengths to a minimum
  • Boom suspension is designed as a parallelogram – hydr. spring-loaded and damped.
  • Soft and smooth boom rest even in hilly terrain and at high operational speeds.
  • 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 torsion-resistant and thus perfectly suitable for the automatic boom controlsystem Leeb BoomControl.
  • Nozzle protection against mechanical damage of the nozzles and wind protection during the development of the spraying fan

Due to the waisted frame design a steering angle of up to 28° is possible even with large tyres

Strong, convincing arguments

  • Less drift and high working speeds due to automatic BoomControl due to low target area distance
  • High working speeds due to hydro-pneumatic boom damping
  • Complete circulation in stainless steel circulatoin tubes to the nozzle
  • Continuous ground clearance
  • Crop protecting, smooth underfloor design
  • Large tyres up to ø 2.05 m possible
  • Gravity-optimised and waisted frame design for large steering angles
  • Novel operating concept
  • Central arrangement of control units
  • Pumping capacity up to 600 l/min
  • Efficient induction hopper made of PE
  • Compact external dimensions in transport position
  • No parts protruding towards the tractor
  • Continuous inside cleaning (CCS and CCS Pro)
  • Spring-loaded axle
  • Integrated overload protection in the boom

Boom does not reach to the front towards the tractor cabin

Boom middle section for working width ranging from 18 to 30 metre, optionally available with pivoted frame.

Three suspension versions are available: non-suspended, elastomer buffer and pneumatic suspension

Large clearance, high comfort and a smooth underbody.

Option

  • Fully integrated axle steering (when reversing automatic centring of the steering axle)
  • Induction hopper made of stainless steel
  • NightLight: powerful LED spraying cone lighting with washing device
  • Pre-field lighting: 2 LED headlights
  • Lighting in the working range of the induction hopper
  • SectionControl (automatic section control)
  • Pneumatic spring-loaded axle
  • Hose drum or high-pressure cleaner for outside cleaning
  • BoomControl expansion with 2 sensors
  • Camera system for the area behind the machine
  • Spacious container deposit facility below the right side cover
  • Individual section layout according to the customer’s requirements
  • Second pressure filter in the rear of the parallelogram ATP Control for automatic regulation of the tyre pressure
  • AutoSelect, automatic switching between the nozzle levels
  • Connect & Fold system to integrate underleaf spraying systems
