Aramis II vs Butler Gold Pro
Two robotic barn machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
Rail-guided all-in-one feeding robot from Tyrolean specialist Hetwin — weighs, cuts, mixes, doses and pushes feed around the clock from an overhead rail, with two horizontal mixing augers producing a homogeneous ration from batches as small as 50 kg. Aimed at medium herds of roughly 50–150 animals; sold and serviced in Switzerland via Harvestore.
Best for: Medium dairy and fattening barns (≈50–150 animals) wanting fully automatic group-specific fresh feeding without a mixer wagon — overhead rail keeps the feed alley clear.Free-driving feed pusher and concentrate dispenser from Austrian feeding specialist Wasserbauer — a 700 kg, 24 V robot that navigates by 5 mm floor magnets set roughly every 2 m, makes up to 99 passes per day and, unlike a plain pusher, uses a special auger to throw feed loosely back to the trough without pressing it. Its 120-litre container (or 2 × 60 l for two components) doses concentrate, minerals or liquids onto the base feed along the way; the drive-over charging station manages batteries automatically.
Best for: Dairy barns wanting more than a pushing drum: fresh, loosened feed plus in-pass concentrate/mineral dosing from one robot, with typical energy use under 4 kWh/day for a 100-cow barn at 14 passes.| Aramis II Verified 2026-07-16 | Butler Gold Pro Verified 2026-07-17 | |
