POLARO® E
12 V spreader with electronic dosing
POLARO® E – professional winter service with a certain added value
With the POLARO® E, you can spread salt, grit, sand, and also fertiliser using virtually any vehicle having a 12 V supply, e.g. a private car, pickup, lorry, wheel loader, mini tractor, quad bike, etc.
All mounting holes required for the attachment are provided in the frame of the POLARO® E. By infinitely adjusting the spreader disc’s rotational speed on the control panel or via the app, the spreading width can conveniently be set and adjusted from 0.8 m (footpath) to 6 m (e.g. parking space) while on the move. In addition, the dosing of the spreading material quantity can also be set on the POLARO® E using the control panel or the LISA app.
The POLARO® E offers, including:
- Stepless adjustment of working width from 0.8 – 6.0 m (up to 12 m as an option)
- Operation via LAS4 control console (optionally with AUTO-DOSIS) or alternatively via app control, including speed-dependent dosing for POLARO® 110 LISA and POLARO® 170 LISA
- Electronic, stepless adjustment of the spreading dosage
- One-sided spreading possible
- Frame, valve, and spreading disc made from stainless steel as standard
- Cables protected in waterproof junction box
- Autostart separates agglomerated spreading material
- Stainless steel agitator
- 24 V operation is possible using a transformer
- OPTIONAL for hopper sizes 110 l and 170 l: Saline agitator for slow-flowing salt (e.g. very fine, damp salt) available at extra cost.

Special features of the POLARO® E
Spreading with comfort and convenience – the LAS 4 control panel with empty indicator.
As well as setting the working width by infinitely adjusting the rotational speed of the spreading disc, all other switching functions are also controlled via the control panel. These include On/Off, setting the adjustment valve for spreading dosage, checking the voltage, etc. What’s more, the control panel issues a visual and acoustic warning when the hopper level is down to minimum or the valve is not in position.
App control instead of a control panel
You already use mobile apps for various applications/devices – don’t want to route any more cables in the driver’s cab, just get in/climb on and get started? Then the LEHNER spreaders with LISA control (LEHNER Intelligent Spreader App) are definitely the right choice instead of the conventional control unit. To operate the spreader, simply use your own mobile device with a holder (not included with the spreader) and the free LEHNER LISA app. Our LISA-compatible LEHNER spreaders are our own closed system solutions, which is why it is not possible to upgrade/retrofit existing LEHNER spreaders with a control panel to an app solution.
Electronic dosing
In contrast to the POLARO®, the discharge rate for the POLARO® E is also set on the control panel or via LISA. Even more convenience is provided by the speed-dependent dosing via AUTO-DOSIS control (accessories), which is now standard equipment on the two POLARO® spreaders with app control.
Stainless steel agitator
The patented LEHNER agitator system guarantees a continuous flow of free-flowing material.
OPTIONAL: AUTO-DOSIS
AUTO-DOSIS automatically adjusts the valve position in line with the driving speed.
After you have selected the material, entered the desired spreading width and quantity per m², the AUTO-DOSIS automatically reacts to driving conditions and controls the dosing valve accordingly. The desired discharge quantity per m² remains constant.
1. AUTO-DOSIS via 7-pin signal socket
Here, the travel speed is recorded via the 7-pin signal socket on the vehicle. In this version, the signal socket also provides the headland management system.
2. AUTO-DOSIS via GPS receiver
The speed is determined by GPS and forwarded to the control panel.
