Cleaner air, quieter lawns—Thun goes electric.

An interview with Toni Zimmermann about the purchase of Switzerland's first AllTrec

Why prioritise electrification?

Healthier crews, lower carbon footprint

  • Eight-hour shifts free of engine exhaust and diesel particulate exposure
  • Up to 25 dB less noise; vibration roughly halved vs. conventional ride-on mowers
  • Eliminates short-trip filter problems and supports Thun’s zero-emission fleet 2035 target
  • Staff report less fatigue and higher concentration after mowing sessions

Which higher-level goals shape equipment purchasing?

National mandates & citizen demand for quiet streets

Swiss Energy Strategy 2050 and cantonal CO₂ laws cascade down to the city council’s procurement rules. Residents, increasingly sensitive to noise pollution, spurred Thun to adopt electric leaf blowers back in 2008. Every new machine now passes a CO₂-and-lifecycle check before tenders go out, ensuring technical feasibility and public benefit align.

Outlook for municipal e-mobility?

50 % electric fleets within a decade

Zimmermann predicts that by 2035 at least half of Swiss municipal machines—tractors, transporters, large-area mowers—will run on batteries. Current hurdles are full-load performance and battery density, but rapid R&D and pilot projects like Thun’s prove the economic case for large-scale adoption of electric utility vehicles.

Key drawbacks of today’s e-machines?

Battery limits & infrastructure challenges

  • Runtime or range can restrain certain high-duty cycles
  • Lithium batteries still pose controlled fire-risk scenarios, though safety has improved
  • Simultaneous charging of an all-electric fleet demands upgraded wiring, switchgear and smart load management
  • Unknown resale values in 10–15 years; however, current battery recycling pathways look promising

How will Thun power its growing e-fleet?

Load-balanced charging plus solar and buffers

The works depot is being fitted with 16 × 22 kW AC chargers and two 150 kW DC fast chargers. A dynamic EMS prioritises vehicles by daily schedule. Rooftop photovoltaics should cover ≈40 % of annual demand; battery storage shaves peaks and cushions outages. Zimmermann calls for federal grants to help smaller towns replicate this charging-infrastructure model.

Why choose the AllTrec?

Quiet power, full-day runtime, rotary deck

  • 1.6 m rotary deck handles debris—ideal for Thun’s lakeside lido
  • Demo showed 8-hour mowing with 22 % battery left
  • < 60 dB(A) allows dawn starts near residential zones
  • Only 100 % electric equipment carrier on the market matching pro-level cut quality—hybrids or smaller electric units could not compete

Planned tasks & future acquisitions

Lido today, reserve for sports turf tomorrow

Primary duty: maintain 20 000 m² of waterfront lawn at a 40 mm cut. Deck height can drop to 30 mm for sports pitches, making the AllTrec a valuable backup. Extension into wider public greens is limited only by deck varieties—a reel deck option would unlock golf courses and stadiums, and Thun is considering more units as the product line evolves.
