Fieldmaster

The Stanley Fieldmaster is a one-seat, two-door utility tractor and a larger, enclosed successor to the open Tractor. Its narrow bonnet sits over the chassis, with a chrome grille, square headlights and an engine compartment under the upper panel. Black-framed fenders cover its wheels, while the cab has tall doors, mirrors and a painted roof. A rear hitch can pull agricultural equipment, and the Fieldmaster appears in green or red with large yellow industrial wheels.

The Fieldmaster has moderate performance for its considerable weight, although it is slow on roads and less capable off road than its size suggests. It manages rough terrain well and can continue through very deep water until the driver is submerged above the head. Its exposed tyres can be disabled by a single firearm shot, making it a poor vehicle for escaping police. It is common around farms in Blaine County, including Grapeseed, Paleto Bay and the Tongva Valley.

Early in the morning and during the evening, Fieldmasters can be parked or working along Vespucci Beach, near the main lifeguard station and Dr. Friedlander's office. Some tow rake trailers to loosen the sand, and similar tractors work around Vinewood Racetrack during the day. In Grand Theft Auto Online, a Fieldmaster at the O'Neil Brothers' farm is used to haul the Graintrailer to Ace Liquor during "Grain trailer". Several also appear during the rabbit hunt in "Uncontrolled Substance".
