ALWAYS AHEAD COBRA 7710T FORAGE HARVESTER

ELHO - MADE IN FINLAND As farms grow larger, the efficiency of machinery used in agriculture also becomes more of a priority. The average size of tractors used on farms has grown tremendously in recent years, and this enables the use of even more powerful tractor-driven implements. In response to this trend, ELHO has introduced the highly efficient tractor-powered Cobra forage harvester to its model lineup. The benefits of finely chopped forage are undeniable. A short cut length provides the best storage properties and a more uniform feed quality. Precision-chopped forage can be stored...

Forks for additive container Pickup with HydroBalance suspension High rear deflector Conveyor belt Camless pickup Hydraulically driven feeder Compression roller Hydraulically driven pickup

Camera on discharge chute Work light Service hatch Automatic sharpening of knives and adjustment of shear bar Direct drive for knife drum FORKS The forks at the back of the Cobra make loading and transporting the additive container easy. The forks are controlled from the ISOBUS terminal. Loading the additive container is even easier by utilising the camera on the discharge chute.

ELHO COBRA MATERIAL FLOW The material flow on the Cobra has been made as simple as possible. After the pickup, the forage travels in a straight line through the entire machine. The conveyor belt, feeder and knife drum are all the same width, which ensures that the material flow and load remain even. The forage passes under the knife drum, and the air flow developed by the knife drum blows the forage at high speed through the discharge chute into the trailer. The Cobra is designed for harvesting grasses and whole grains, so there is no need for an accelerator. The absence of an accelerator...

AUTOMATIC DOSING OF SILAGE ADDITIVE The forks at the back of the Cobra make loading and transporting the additive container easy. The forks are controlled from the ISOBUS terminal. Loading the additive container is even easier by utilising the camera on the discharge chute. The Cobra features automatic dosing of the silage additive. The desired dosage is adjusted from the ISOBUS terminal, and the automation takes care of the rest. The dosing starts automatically when forage is detected in the knife drum. The automation ensures that additive is only dosed when there is forage in the...

PICKUP The Cobra forage harvester uses a pickup developed by ELHO. The starting point for the design was to develop a pickup that works as efficiently as possible alongside the harvester. The powerful feeder unit and knife drum place tough demands on the pickup, which is why the Cobra’s pickup is designed for handling large amounts of forage. The pickup features the proven AutoBalance suspension. Beneath the pickup are three large support rollers that, combined with the hydro-pneumatic suspension, ensure a very low surface pressure. The surface pressure of a single support roller can be...

FEEDER UNIT The feeder unit on the Cobra features three feed rollers and two compression rollers.. The feed rollers are hydraulically driven, and all rollers have the same rotation speed. Changing the rotation speed of the feed rollers adjusts the cut length of the forage, which is steplessly adjustable from 4 to 18 mm. The adjustment is made from the ISOBUS terminal. By decreasing the number of knives to 16, a cut length up to 36 mm can be achieved. There are two pre-compression rollers above the feed rollers. The pre-compression is hydraulic, and the compression force is also steplessly...

KNIFE DRUM When designing the Cobra, the aim was to develop a forage harvester that is as straightforward and efficient as possible. To optimise efficiency, the Cobra features direct drive to the knife drum. Power is transmitted directly from the PTO shaft to the knife drum without a gearbox. Direct drive ensures that all the power from the tractor is transmitted to the harvester without power losses. The absence of a gearbox also reduces the need for maintenance. The knife drum has a total of 32 knives in two rows. Thanks to the ingenious position of the knife drum, it is very maintenance...

DISCHARGE CHUTE The powerful air flow developed by the knife drum combined with the design of the discharge chute effectively blows the forage regardless of the conditions. The height of the discharge chute reaches up to 5.5 m, which makes filling even tall trailers effortless. The discharge chute turns backwards and down into the transport position, so that the transport height remains moderate. The discharge chute’s wear-resistant body and sturdy swivel base guarantee a long service life. The discharge chute has a camera, which makes filling trailers effortless. The operator can monitor...

CONTROL SYSTEM The Cobra forage harvester is ISOBUS compatible and can be controlled either from the tractor’s ISOBUS terminal or from the optional ISOBUS terminal. The Cobra features advanced automation that makes the operator’s work easier, including headland automation and automatic dosing of silage additive. The Cobra has a wide range of adjustments, which allow the operator to get the end result of his liking. Headland turns are made easy with headland automation. When approaching the headland, the driver only needs to use one function that stops the feed and pickup while raising the...

OPERATING METHOD TELESCOPIC AXLE The efficiency of the forage harvester is essentially affected by logistics, so it is important that the operator of the tractor pulling the harvester and the driver of the tractor pulling the trailer work seamlessly together. The design of the Cobra enables the tractor pulling the harvester and the tractor pulling the trailer to drive close together, almost parallel, which makes filling the trailer much easier. The trailer is filled from the left side of the harvester. The operator can monitor the filling of the trailer from the screen inside the cab...
