What Stewart Trailers does
Stewart Trailers, trading as Stewart Agricultural Limited (Scotland registration SC165316), is a privately held UK manufacturer of custom-built agricultural and commercial trailers founded in 1988 by James and Mandy Stewart. The company operates from a modern manufacturing facility at Broadward, Daviot, Inverurie, Aberdeenshire, in north-east Scotland, with a headcount in the 11-50 employee range.
The product portfolio centres on four tipping trailer ranges: the PRO Series (Hardox-bodied professional tipping trailers), Road King (three-axle, air suspension, optional rear-steer), Legend (mild steel standard range relaunched in 2025 with reversing camera and enhanced lighting), and EDGE (small dropside Hardox trailers). The line-up is broadened by Construction & Dumper trailers (10-20 tonne capacities), Flat Trailers, Bale Handling Trailers, Low Loader Trailers, and aluminium Livestock Containers with welded effluent-leak prevention. Optional extras include a factory-calibrated On Board Weigh System accurate to within +/-1% via four weigh cells, a single-line Central Tyre Inflation system with 45-second field-to-road transitions, automatic lubrication, hydraulic cover systems, and a specialised carrot trailer.
Revenue is generated through hardware sales of trailers built to order, with pricing quoted on enquiry rather than published. The go-to-market combines a domestic and international network of appointed Stewart agents with a direct sales team (Sales Representative and Sales Administrator), supplemented by agricultural trade show presence (LAMMA, Royal Northern Spring Show, Royal Highland Show), factory tours, downloadable brochures, and social/YouTube content. The primary customer base is UK agricultural contractors and farmers, with secondary exposure to construction sites and livestock transport; documented long-tenured customers (Wilson Contractors 20+ years; Suggitt Farm Services with 15 trailers) indicate a repeat-purchase mid-market model concentrated in UK agriculture.
