The TMG-TAM40 Side Boom Mower is a versatile tractor-mounted reach mower designed for roadside, ditch, field edge, embankment, hedge, and vegetation maintenance. With a 40" cutting width, 114" maximum reach, and 176° head angle adjustment, it gives operators the flexibility to cut in offset, inclined, vertical, and horizontal positions. 

Built for dependable field performance, the TMG-TAM40 features a sturdy arm structure with torsion-resistant profiles and bushed, greasable joints. Its self-contained hydraulic system includes a 17 gal oil tank and oil cooler, helping prevent hydraulic cross contamination between the mower and tractor. A dual hydraulic pump powers the cutting attachment and hydraulic cylinders separately for smoother control and consistent operation. 

Equipped with 40 flail blades and designed for 3-point hitch Category 1 tractors, this mower is a practical solution for farms, acreages, municipalities, and property maintenance crews. Whether maintaining road edges, clearing banks, trimming hedges, or managing field borders, the TMG-TAM40 helps improve reach, control, and mowing efficiency. 

TMG also carries a similar hydraulic arm mower: TMG-TAM32
