Stewart Trailers

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.

• EDGE Tipping Trailer Range Small dropside trailers built with Hardox body with multi-function back door including spreader chain points. Doors hinge from top or open to side, integral body prop for safe maintenance. Approved members of the 'Hardox in my Body' scheme since 2013.
• Construction & Dumper Trailers Three construction trailer types: Construction Dumper trailers with scow tail, Construction Monocoque trailers with flat floor, and Construction PRO trailers with Hardox body. Models range from 10 to 20 tonne capacity for aggregates and construction materials handling.
• Flat Trailers Versatile flat trailers available with either 4mm steel floor or 28mm Keruing floor. Models range from GX 8 FT to GX 18 FT with body lengths from 6100mm to 10900mm, and the range is recommended for use with livestock floats.
• Bale Handling Trailers Specialised trailers for transporting round or square bales, built from 26ft to 36ft based on the flat trailer range. Available in two models for two rows or three rows high of bales, with retaining frames for secure transport.
• Low Loader Trailers Heavy-duty trailers with 45mm Keruing floor and hydraulically operated ramps (standard on 15 and 22 tonne models). Models include GX 10 LL, GX 15 LL and GX 22 LL with body lengths from 6100mm to 7900mm.
• Livestock Containers Aluminium-fabricated livestock containers for cattle and sheep transport, with strong but lightweight construction. Fully welded design with pressed side sheets welded to box section posts at 1150mm intervals, preventing effluent leakage. Features include internal doors, folding decks and hydraulic ramp operation.
• Central Tyre Inflation (CTI) System Single-line CTI system that constantly monitors tyre inflation and adjusts automatically, allowing rapid reduction to field inflation for off-road use and quick inflation for road transport (from field to road pressure within 45 seconds). A speed sensor detects if the operator forgets to inflate when leaving the field.
• On Board Weigh System Weighing system from the commercial vehicle sector, accurate to within ±1%, using four weigh cells placed below the four corners of the tipping body and factory-calibrated. Three display options: chassis-mounted, remote cab unit, or wireless remote display.
• Automatic Lubrication System Automatic greasing system comprising pump with integral reservoir, primary line with distribution blocks, metering units, and secondary lines. Operates via compressed air (on trailers with air brakes) or electric pump with timer, distributing grease optimally during operation.
• Hydraulic Cover Systems Two types of hydraulic covers: a front-to-back mesh cover to retain load, and a side-to-side waterproof roll cover to keep load dry. Powered by a hydraulic motor and can be used with standard body or extension sides.
• Specialised Carrot Trailer Specialised trailer designed for carrot transportation, with features tailored to this specific agricultural application.
