STAINLESS STEEL PANELS
Strong uprights and corrosion proof stainless panels are proven as the best construction system for acidic and abrasive silage.
13MM HIGH TENSILE CALIBRATED LINK CHAINS
Deliver unmatched strength and reliability. Tested to 24.5 tonnes per chain, providing a massive 49 tonnes of total chain strength.
LOW MAINTENANCE FLOOR ADJUSTMENT
Floor chains are simple to adjust with stainless steel chain tensioners that won’t rust and are easy to reach
POWERFUL GEARBOXES
High quality powerful gearboxes provide loads of torque for the floor and elevator power transmissions
RUBBER BELT OR ROLLER CHAIN
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
SCALE-READY
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.
GALVANISED ELEVATOR BARS
8mm heavy duty galvanised elevator bars have an aggressive tearing action to handle the toughest loads. HDPE runners for the elevator bars provide quiet and smooth running.
SEE-THROUGH BACK GATE
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.
DRAWBAR
Narrow for tight turning and the swivel tow eye is bolted on for easy replacement or upgrade to a K80 ball hitch. Easily add a hydraulic jack or quick hitch stand.
MESH FRONT SCREEN
This gives the operator great visibility to the load and through the wagon for reversing.
SEALED AXLE BEARINGS
Over-sized hubs have sealed bearings, and can be swapped out for brakes or completely replaced if damaged. Heavy duty walking beams with replaceable Vesconite™ pivot bushes.
MUDGUARDS
Sturdy angled mudguards keep dirt and mud spray to a minimum.
LADDER
Access the top of the feed bin. Can be fitted to either side
HDPE PLASTIC FLOOR
15mm HDPE plastic floor is tough and slippery so the load moves forward easily.
LOAD SENSING HYDRAULICS
Load sensing hydraulics ensure an even feed flow is maintained. The feed rate is adjusted manually and can be upgraded to wireless and automatic rate control linked with the optional weighing system.
MAIZE PLATES
Extended maize plates at the base of the elevator frame reduce spillage of fine chop feeds.
EXTERNAL CONVEYOR BELT TENSIONERS
Belt adjustment is simple with stainless steel tensioning bolts that are easy to reach.
GALVANISED FLOOR BARS
Extra heavy duty galvanised 65x35 RHS floor bars are bolted to the 13mm floor chains for easy replacement if ever needed.
Technology
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 relays wagon data to the display mounted in the tractor or a smartphone. 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.
You have two user display choices. Both use a wireless connection with a huge operating range of up to 100 metres, or line of sight.
Either choose the CANBUS 7-inch touch screen controller with an intuitive layout and responsive touch controls. This lets you monitor weight changes and make informed decisions from the tractor seat. The touch screen mounts inside the cab and ensures accurate loading and feed management, no matter what the weather conditions are. The on-board weighing system eliminates guesswork, with the scales and feed rate controls at your fingertips while you’re loading and operating the wagon.
Alternatively, if you don’t need electronic rate control, choose a lower-cost simplified system which displays the scale weight on your own phone or tablet. Either way, adding scales will improve your feed management and give you 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.

CHOOSE A MODE TO SUIT YOUR FARM
Wireless Scales With Manual Feed Rate Control
– Available with either the full CANBUS touch screen system or the phone-based display. The load in the wagon is displayed in kg with tare and gross scale functions at your fingertips, and the feed rate is controlled manually on the hydraulics. Requires load cells.
Wireless Electronic Rate Control Without Scales
– Only available on the full CANBUS touch screen system. Upgrade from manual control so that the feed rate can be adjusted with the controller from the tractor seat on the move – particularly useful for feeding out large bales, where the rate needs to be changed often. Requires a solenoid valve. Load cells optional.
Wireless Scales And Fully Automatic Feed Rate Control
- Only available on the CANBUS touch screen system. Upgrade to wireless scales with three different feed rate control modes. The load in the wagon is displayed in kg with scale functions at your fingertips. To feed out simply enter a percentage feed rate, or the amount you want to feed in kg, or your total feed run length and how much you want to feed out. The wagon does the rate control calculation and evenly discharges the load as required, automatically shutting off at the end of the run to eliminate over-feeding.
