PTO GENERATORS

Flexible power for modern agriculture

Whether the grid is unavailable, unreliable, or part of a backup strategy, Power Take Off (PTO) generators provide flexible agricultural power. By harnessing the power of a tractor, PTO generators deliver a dependable electricity supply, transforming existing farm equipment into versatile, on-demand power.

STANDBY POWER. MOBILE FLEXIBILITY.

Designed for both standby and mobile applications, PTO generators can be installed as backup systems, supporting critical operations such as dairy farms during grid outages, or integrated into automatic mains failure (AMF) systems for seamless continuity of supply. At the same time, they provide mobile power capability, enabling electricity to be deployed wherever it is needed across the farm.

From livestock operations to field-based equipment, PTO generators ensure productivity, protect assets, and maintain continuity in all conditions.

POWER WHERE AND WHEN YOU NEED IT

Harness the power you already own. PTO generators enable a tractor to generate electricity wherever it’s needed on the farm, without the cost of a permanent grid connection. Utilising a PTO generator, it’s possible to power:

Dairy parlours and milking systems during outages	Grain dryers and processing equipment during harvest
Irrigation pumps in remote fields	Barns, workshops, and temporary installations

COMPLETE PTO GENERATOR SOLUTIONS

Every PTO generator arrives as a fully assembled unit, built around a heavy-duty oil-bath gearbox matched to the alternator’s output and a welded three-point linkage frame for fast connection to the tractor.

There’s no separate sourcing or assembly required, so farms can utilise independent power etc. switch between grid-connected and independent power as soon as the unit is connected.

RANGE OVERVIEW – GO, PRO, MAX

Three product ranges provide solutions for every type of agricultural operation:

PRO Range (20–82.5 kVA)

Designed for dairy and mixed farming operations, featuring brushless alternators with digital AVR for precise voltage regulation and consistent performance.

MAX Range (30–150 kVA)

Heavy-duty solutions for commercial farms, with robust construction for continuous or year-round outdoor use, utilising a zinc-coated frame. Control with digital AVRs..

ENGINEERED FOR AGRICULTURAL PERFORMANCE

Agricultural loads bring their own demands, and the alternator is built to match them. Motor starting capability reaches up to 400% overload for 20 seconds on GO models and 300% on PRO and MAX, enough to handle the inrush from pumps, compressors and milking equipment. PRO and MAX models add AVR-controlled voltage regulation to within ±1%, compared with ±5% on transformer-controlled GO units.

The alternator itself runs in a double-bearing configuration, with a full shaft supported at both ends independently of the gearbox. That keeps the tractor’s PTO weight evenly distributed rather than loading the gearbox directly, which is what gives these units their reliability under continuous, variable farm use.

BUILT FOR HARSH AGRICULTURAL ENVIRONMENTS

A range of upgrades is available to extend that protection further. These include advanced insulation systems such as Total+ adding winding resilience in harsh environments. Alternatively, IP45 filter protection kits can add enhanced resistance to dust and water spray, while anti-condensation heaters prevent internal moisture build-up during storage. Zinc-coated frames provide corrosion resistance for outdoor installations, and advanced insulation systems, including enhanced winding protection, can support use in more aggressive environments.

INTELLIGENT CONTROL AND OPERATION

Control systems are designed for ease of use and operational flexibility. Rear-facing control panels keep the display visible from the tractor seat, housed in IP54-rated enclosures for environmental protection. The intelligent PTO250 power controller unlocks the full potential of the PRO and MAX PTO alternator models by controlling nominal current and removing the breaker-calibration constraints typically imposed by equipment manufacturers.

DESIGNED FOR COMPATIBILITY AND SAFETY

Correct PTO generator operation depends on proper matching between tractor and alternator. Our systems are designed to align with standard PTO speeds, typically 540 or 1000 rpm, alongside tractor horsepower, torque characteristics and the specific electrical load and starting demands of the application. Integrated protection systems then ensure safe operation during overload, underspeed and transient conditions.

CERTIFICATIONS AND STANDARDS

Our PTO alternators are designed and manufactured to international standards, including EN 60034-1 (Rotating Electrical Machines), EN 60204-1 (Electrical Equipment of Machines), and the EN 61000 series (Electromagnetic Compatibility), with Class H insulation standard throughout the range.

Every PTO alternator is backed by a 2-year manufacturer’s global warranty, with extended cover available on request.

EXPERT ADVICE, WHEN YOU NEED IT

Choosing the right PTO generator depends on your tractor’s capability, your farm’s load profile, and how the system needs to integrate with existing power. Our technical teams can help with sizing, output matching, AMF or standby integration, and environmental protection options.
