What Giltrap Engineering does

Giltrap Engineering Limited is a privately held New Zealand agricultural machinery manufacturer headquartered in Otorohanga, owned by Belinda and Craig Mulgrew since 2001. The company operates two legacy brands — Giltrap (founded 1959) and Duncan (161-year heritage, acquired through Clough Agriculture in 2018) — and manufactures seed drills (Renovator tine drills and Enviro disc drills), forage wagons (G-MAX and G-Series), bale feeders, MultiPlus feeders, fertiliser spreaders, slurry spreaders (5,000L–20,000L), and tip trailers (GT Series 6–20T and Construction Series 17–25T) at two New Zealand plants in Otorohanga and Timaru. Technical differentiation centers on Baker Boot inverted-T seed-slot technology, the BioBlade opener (worldwide exclusive license from Cross Slot inventors), the E-Drive electric rate-control system with the Duncan Seed Drill App, and the G-MAX wireless weighing and feed-rate automation released in 2006.

Giltrap generates revenue through hardware sales of equipment and genuine parts, with no e-commerce or public pricing; all transactions are quote-based and routed through an independent dealer network. The New Zealand dealer footprint exceeds 50 named locations spanning every major farming region, and the company maintains dedicated entities or websites in Australia (Giltrap Ag Equipment Pty Ltd, 4,000 sqm Melbourne facility established 2005), the United Kingdom, Ireland (via Tom Tierney), the United States, Japan, South East Asia, South America, and South Africa. Primary customer segments are NZ dairy farmers, drystock farmers, and agricultural contractors, with secondary reach into horticulture/viticulture (via Duncan Vineyard and Orchard Seeders) and construction/earthworks (via Construction Series trailers). Growth has been driven by a sequence of acquisitions — DML Equipment (2005), Spreaders NZ/Buckton Engineering (2009), Clough Agriculture (2018) — and by recent product launches including the BioBlade opener, Duncan Single Disc Drill, and new G-Series forage wagon (all 2026).
