Slopehelper vs Drever 120
Two autonomous tractor machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
Slovenian heavy-duty autonomous tracked platform for vineyards and orchards — a full-cycle electric workhorse with 19+ hinged attachments covering mowing, mulching, spraying, harrowing, leaf removal, blossom thinning and harvest support. Suspended caterpillar tracks and gravity-stabilised cargo let it work slopes up to 42° where wheeled robots cannot go.
Best for: Vineyards and orchards on steep terrain wanting one electric platform to replace tractor passes across the whole season: soil work, canopy work, spraying and transport.Swedish electric autonomous tractor (120 hp) from Traktorarvid AB, a small Uppsala-area startup founded in 2018. Two swappable batteries let one work the field while the other charges on-farm (from solar or grid), and its lighter weight is pitched to cut soil compaction versus a comparable diesel tractor. Still pre-commercial — the manufacturer is building a pre-series run of 5 units through 2025-2026, with full series production not expected until 2027.
Best for: Buyers willing to engage as an early pilot/pre-series partner with a small Swedish startup — mainly large-scale cereal and row-crop operations interested in electric, driverless draft power and reduced soil compaction.| Slopehelper Verified 2026-07-17 | Drever 120 Verified 2026-07-19 | |

| Specifications | ||
| Power source | Battery-electric · 48 V EV48 FEV lithium system · 8–12 h operation, 5–8 h recharge | Battery-electric — two swappable batteries (one works the field while the other charges on-farm) |
| Required tractor power | Not required (self-propelled tracked platform, ~2 t load capacity) | 120 hp equivalent, fully electric, driverless/autonomous |
| Dimensions | 2.60 × 1.61 × 1.23 m | Not disclosed; manufacturer states Drever is smaller than a comparable conventional tractor |
| Weight | 1,750 kg | Not disclosed exact figure; manufacturer states approximately one-third the weight of a comparable conventional tractor |
| Min farm size | Not disclosed | Not disclosed; manufacturer states Drever suits both small and large farms |
| Productivity | 8–12 h continuous operation per charge depending on task | Not independently measured; manufacturer's design target, reported by Landbrugsavisen (2023), is 2-3 Drever units replacing one ~400 hp conventional tractor — a stated goal, not a deployed result |
| Max speed | 5 km/h (working range 0.5–5 km/h) | Not disclosed |
| Sensors | R-WAVE RTK/GNSS autonomy · 2D MP radar (±30 mm, 0.5–6 m) · encoders · dual electromechanical bumpers and radiowave safety scanners | Custom-developed autonomous steering and GPS-based navigation with smartphone-app monitoring and alerts; detailed sensor suite (e.g. lidar, cameras) not disclosed in accessible sources |

| EU context | ||
| CE marking | CE status not published; Slovenian manufacturer selling in the EU | Not confirmed — no CE-marking evidence found on the manufacturer's site or in press coverage; Drever 120 is still in prototype/pre-series phase and not yet placed on the general market. |
| Machinery Regulation | Placed on the EU market by PeK Automotive; Regulation (EU) 2023/1230 autonomous-machine provisions apply | Would fall under Regulation (EU) 2023/1230 autonomous-machine provisions once placed on the market; not yet confirmed for the pre-series units. |
| CAP subsidy | Zero-emission electric platform supports fuel/emission-reduction and eco-scheme measures under CAP | Not directly tied to CAP eco-schemes; development has been EU co-financed via the EIP-Agri (European Innovation Partnership for Agriculture) programme. |
