Efficiency and precision
The Leeb TD:
Technology for utmost efficiency
The basis
- Solidly designed frame made of quality steel
- Hydraulically spring-loaded tandem axle with level compensation
- Solid drawbar connection for large clearance with standard lower linkage in a trailer hitch ball
Steering axle – less tramline damage (optional)
- Kingpin steering of both axles for a smooth boom position and an exact following of the tractor tracks
- 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
- Due to the special frame design the tank reaches down below the frame height – high stability at high operational speeds and on slopes
- Minimum residual quantities of chemicals
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
Mixture tank
- High quality tank made of PE or stainless steel
- Easy cleaning and residue-free inside walls
- No mixture residues on the absolutely smooth inside walls
- Stainless steel: welded on the inside and on the outside
- Double tank concept for optimum weight distribution and traction in the field
- Round tank shape for low flushing powers
- PE fresh water tank with a capacity of approx. 850 litres and stainless steel fresh water tank with a capacity of 900 litres: enough water for a complete inside cleaning as extremely few residues remain in the system.
CCS Pro
- Electronic operation on the pressure and the suction side for a complete control also 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
- Oil-driven (Load Sensing) centrifugal pump (1 000 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.
Theodor Leeb “The objective when developing the 12 TD was to complete the well-known efficiency of the Leeb sprayers with an even larger tank capacity. With 12 000 litres we create reserves in the field especially if there a long distances between farm and field and in case of high water application rates. To maintain the vertical load in complex working conditions, the two tanks and their contents are controlled intelligently.”
Leeb TD details
- Tank capacity 12 000 litres
- Low gravity centre of the spraying tank
- Double tank concept for a vertical load optimised weight distribution and optimum traction force transfer in demanding terrain
- Mixture barrel optionally made of PE or stainless steel
- 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 againt mechanical damage of the nozzles and wind protection during the development of the spraying fan
Steering angle of up to 28° at the rear axle also possible with wide tyres due to the waisted frame design.
Strong, convincing arguments
- Highly efficent due to 12,000 litres mixture tank
- Intelligent and independent control of the two mixture tanks to optimize the vertical load
- 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 circulation 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 1 000 l/min
- Efficient induction hopper made of PE
- Compact external dimensions in transport position
- No parts protruding towards the tractor
- Continuous inside cleaning
- Spring-loaded axle
- Integrated overload protection in the boom
- Second pressure filter at the rear in the parallelogram
- Innovations like PrecisionSpray
