Giltrap has always been a pioneer at introducing industry-leading technology to farmers.
The new G-MAX forage wagon builds on our decades of experience to bring you an industry leading wagon for the modern age.
Our fresh contemporary design is packed with exciting new features and upgraded technology from the best in the business so that you can feed out precisely, and reliably, whenever you need to.
Simple to use and easy to maintain while delivering exceptional performance, the G-MAX wagon will take your feeding programme to the next level.
Our comprehensive range is designed to handle all feed types, including grass, maize, whole-crop cereals, silage, and both long and precision-cut round or square bales, catering to farms of all sizes.
Choose from a broad range of options and accessories like wireless weighing and feed rate automation for precision feeding.

Watch our video where Matt chats about the key features of the Giltrap G-MAX wagon.
Key features are also illustrated below.

Strong uprights and corrosion proof stainless panels have been proven for decades to be durable and the best protection against acidic and abrasive silage

Calibrated link chains are unbeatable in harsh silage conditions, compared to lower strength roller chains which will corrode and seize. Our 13mm high tensile calibrated link chains have a tested breaking strength of 22 tonnes per chain for exceptional reliability. Additionally, large diameter high tensile chain sprockets are designed for high torque, maximum chain engagement, and low wear

High quality powerful gearboxes provide loads of torque for the floor and elevator power transmissions

Choose from a rubber belt or roller chain and slat side delivery conveyor. The standard width is 1200mm wide to handle all types of feed, including large square bales

All wagons are ‘scale-ready’ with a double chassis and can have electronic load cells fitted for mobile weighing to improve your feeding accuracy and feed management

8mm heavy duty galvanised elevator bars have an aggressive tearing action to handle the toughest loads. UHMWPE plastic slides for the elevator bars for quiet and smooth running

The heavy-duty see-through back gate includes crash lock for load reversing, and a safety cover for the floor chains. It can be held open with a stay for maintenance access

The drawbar is narrow for tight turning and the swivel hitch is bolted on for easy replacement. Easily add a hydraulic jack or quick hitch stand

The mesh front screen gives the operator great visibility to the load and through the wagon for reversing

Over-sized hubs have sealed bearings, and can be swapped out for brakes or completely replaced if damaged. Heavy duty walking beam axles with replaceable Vesconite™ pivot bushes

Wireless Technology (optional)
G-MAX WIRELESS SCALES AND FEED RATE AUTOMATION
Our wireless weighing and feed rate control technology was the first of its kind on forage wagons and is used to relay wagon data to the display mounted in the tractor. Designed and manufactured specifically for Giltrap forage wagons, the latest G-MAX system builds on years of experience and proven in-field reliability, using the latest technology.
The 7-inch touch screen controller has an intuitive layout and responsive touch controls, letting you monitor weight changes and make informed decisions from inside the tractor. The wireless connection has a huge operating range of up to 100m, or line of sight.
The touch screen mounts inside the cab and ensures accurate loading and feed management, no matter what the weather conditions are. On-board weighing systems eliminate guesswork, with the scales and rate controls at your fingertips while you’re loading and operating the wagon.
You will improve your feed utilisation and have confidence that the correct ration portions are fed out.
The robust scale design is configured with either 4 or 6 industrial shear beam load cells and heavy-duty mounts for durability and long life. Bespoke stainless steel convex/concave pivot washers ensure accurate scale readings on the move.
GREAT TECHNICAL FEATURES INCLUDE:
• Programmable automatic shutdown function to conserve the battery life
• Automatic fast charging of the on-board 12-volt battery
• Compact RAM mount for the controller in the tractor cab
• Easily accessible electronics junction box for servicing and upgrades
• Control and weighing modules can be fitted aftermarket as an upgrade
• The controller module has LEDs for simple user information and diagnostics
• The touch screen controller can easily be shifted between tractors with the addition of a second RAM bracket and power loom
• Remote technical support by Giltrap on your controller in the field. Our technical support team can access your control system with your permission, to troubleshoot and install upgrades
