Field defenses

Six enemies of an ag harness

Ag is brutal on wiring. We pick materials, shielding and routing hardware for each of these explicitly.

Dust ingress

IP67 connectors · gel-filled M12 · double-wall heat shrink.

UV exposure

TPE and XLPE jackets carbon-black-filled for 10+ yr open-field service.

Fuel & hydraulic oil

Nitrile-resistant jackets · ASTM D471 qualified.

Vibration

P-clips every 300 mm · anti-fretting silicone sleeves.

Livestock / rodents

Rodent-deterrent braid over chassis runs; reinforced hitch exits.

Wash-down

IP69K pressure-wash rated at the cab and hitch area.

Implement plug support

Every implement speaks ISOBUS

We deliver the ISOBUS In-cab (ISO 11783-2) connector pre-wired, so any implement — seeder, sprayer, baler, mower — plugs in and talks to the tractor display.
