Product description

Forage wagon with rotor, cutting unit and 41 m³ capacity

The wagon picks up the crop with a cam-track-controlled pick-up, feeds it through a loading rotor and a cutting unit with 45 knives, then unloads it using the hydraulic scraper floor. The tandem axle is hydraulically sprung, and the rear axle is forced-steered.

Forage wagon instead of transport wagon – what’s the difference?

This is the key difference when comparing it with the basic silage wagon in the same range: This wagon loads itself.

• A transport wagon is filled by a forage harvester or loader – it needs a second machine and a second person.
• A forage wagon picks up the windrow itself. One driver, one machine, one operation.

When does it make economic sense? On small and medium-sized fields, on scattered plots and where the route to the silo is short – wherever a multi-vehicle harvesting team would be underused.

45 knives – cutting length determines silage quality

The knife bar carries 45 individually mounted knives.

Why shorter-chopped forage is better:

• Better compaction in the silo. Short stems can be packed more tightly – less residual air means less heating and fewer losses.
• Better feed intake. Short-chopped forage is easier to mix and is eaten more readily by livestock.
• Less strain on the mixer wagon. Forage that is already short does not need to be chopped again.

Each knife pivots independently and moves out of the way if it hits a foreign object, rather than breaking. When there are stones in the windrow – almost unavoidable on permanent grassland – this is the difference between a bent knife and a destroyed knife bar.

Cam-track-controlled pick-up with jockey wheel

The cam track guides the tines so that they pick up the crop and retract just before transferring it. This ensures clean pick-up with no crop losses and prevents stems from being pulled along.

The jockey wheel keeps the pick-up at the correct height above the ground – important on uneven grassland: too low means soil and stones in the forage, resulting in poor fermentation; too high means crop is left behind.

Loading rotor with spirally arranged rows of tines

The eight rows of tines are arranged spirally and made from highly wear-resistant steel.

Why the spiral arrangement matters: The tines engage one after another rather than all at once – distributing the load throughout the rotation instead of applying it to the drive in jolts. The wagon runs more smoothly and peak power demands on the tractor are reduced.

Hydraulic scraper floor and two-stage chain conveyor

Four link chains with slats move the crop towards the rear during unloading; the chain conveyor uses six chains and a two-stage hydraulic drive.

What the second stage does: During loading, the floor runs slowly to compact the crop; during unloading, it runs quickly to clear the load promptly. A single-stage drive always has to compromise.

Prepared for metering rollers

The loading platform with bolted-on sides is prepared for fitting powered metering rollers.

What metering rollers do: They loosen the compacted crop during unloading and discharge it evenly, rather than pushing it out as a block. This is the right solution for directly filling feed tables and mixer wagons.

Hydraulic tandem suspension with forced steering

The front axle is rigid and the rear axle is forced-steered; both are hydraulically stabilised and adjustable, with four steel half-leaf springs.

• Forced steering protects the grass sward. On permanent grassland, every torn-up patch means lost yield for years.
• The hydraulic suspension keeps the wagon level on slopes and uneven ground and balances the axle loads.
• Adjustable means the height can be adapted to the situation – during loading, unloading or road travel.

Operation from the tractor

The central hydraulic system is controlled via an operating terminal in the cab. The pick-up, rotor, scraper floor, tailgate and running gear are all operated from there – the driver stays seated.

Transparent front panel

The view into the load compartment shows the fill level without anyone having to get out. With a capacity of 41 m³, this is a practical way to check whether there is room for another windrow or the load is full.

Aluzink sides and two-component paint finish

The sides are made from trapezoidal profiles with an Aluzink coating – corrosion-resistant and lightweight at 0,75 mm thick. Every kilo in the body matters on a forage wagon, because it directly reduces the payload. The frame, drawbar and axles are protected with a UV-resistant two-component paint finish.

Applications

Grassland and forage-growing farms, dairy farms, agricultural contractors, biogas plants using grass silage, and farms with scattered plots and short routes to the silo.

Operating notes

• Check the towing vehicle's drawbar load: up to 4.000 kg.
• Requires 182 PS or 133,8 kW, as well as connections for the central hydraulic system and operating terminal.
• Adjust the pick-up height using the jockey wheel – too low means soil and stones in the forage.
• Sharpen the knives regularly; blunt knives tear rather than cut and significantly increase power requirements.
• Before working on the knife bar or in the load compartment, disengage the PTO and stop the engine.
• Check the PTO shaft and safety guards before every use.
• Observe the maximum height of 3.990 mm – check entrances, silos and overhead lines.
• Observe the width of 2.850 mm when travelling on the road.
• Check chain tension regularly and lubricate as specified by the manufacturer.

Frequently asked questions

What is the difference between the forage wagon and the silage wagon in the same range?

This wagon loads itself: it has a pick-up, loading rotor and cutting unit with 45 knives. The basic silage wagon has to be filled by a forage harvester or loader, so it needs a second machine.

How much can the wagon hold?

41 m³, with a payload of 12.500 kg and a permissible gross weight of 24.000 kg.

How many knives does the cutting unit have?

45, each individually mounted and pivoting. If a knife hits a foreign object, it moves out of the way rather than breaking.

Why is shorter-chopped forage better?

It compacts better in the silo – less residual air means less heating and fewer losses. It is also easier to mix and is eaten more readily.

Can I retrofit metering rollers?

The loading platform is prepared for fitting powered metering rollers.

What does the tractor need?

182 PS or 133,8 kW, a coupling suitable for a 4.000 kg drawbar load, and connections for the central hydraulic system and operating terminal. A wide-angle PTO shaft is included.

What are the benefits of forced steering?

It protects the grass sward. On permanent grassland, every torn-up patch means lost yield for years. It also reduces the turning circle.

How can I see the fill level?

Through the transparent front panel – without getting out.
