The XCV range comprises of three models 32ft (9.6m), 36ft (10.8m) & 42ft (12.6m) working width.
The models feature a spring loaded pivoting adaptor plate system which when coupled to the spring loaded gauge wheels enable the wider heads follow the ground contours.
The headers are all centrally mounted and therefore compatible with controlled traffic applications.
8 Rows of stripping fingers are arranged on the rearwards rotating rotor. They can be orientated either cup up (aggressive) or cups down (non-aggressive) depending upon the crop to be harvested. Hard threshing dryland wheat needs aggressive fingers whereas easy threshing soft wheat requires non aggressive fingers.
The XCV utilizes the proven variable speed belt drive system, rotor speed is controlled using an electronic cab mounted monitor. An electric actuator controls the drive pulley in conjunction with a posi-torque spring tension system fitted to the front pulley.
The in cab monitor allows the operator to adjust the speed of the stripping rotor by controlling an electric actuator that adjusts the drive pulley. The speed of the rotor and the auger are displayed and include an alarm system to aid the operator.
This is adjusted up and down using the combines reel lift and lower control and is used to control the stripping rotor intake in different height standing and lodged crops.
The top hood serves two purposes, firstly it seals the area above the auger to prevent any grain or dust escaping. The underside of the top hood acts as a deflector, taking the crops stream from the underside of the adjustable crop deflector and directing it into the bottom of the auger trough.
The auger operates at a fixed speed between 180rpm and 200rpm depending upon the combine output speed, it is driven via a mechanical slip clutch. The auger is fitted with specially shaped centre mounted spiral paddles, these feed the grain rearwards into the feederhouse from the header. A two piece auger is used in the wider models (XCV42 & XCV36) to provide greater strength across the span.
A spring loaded pivoting adapter plate system which works along with spring loaded gauge wheels allow the header to follow the ground contours with its lateral movement.
Four springs are used on the right hand side to compensate for the heavier left drive end. This allows the header to be centrally mounted and can be utilized in a controlled traffic system.
The adaptors are available for John Deere, Case, Claas, New Holland and Agco Combines
The wheels are designed to stabilise the header as it travels through the field providing positive ground contact to enable the spring loaded adapter plate system to move with the ground contours.

The auger is fitted with a slip clutch, this can slip if an excessive amount of straw is picked up at too high a ground speed.
The rotation of the rotor very successfully harvests crops lying on the ground because it has a picking up action.
Not really, the stripper head works by a rotary mechanical action rather than air flow.
No, the rotary action of the header is very gentle on the grain making the Shelbourne header popular with seed growers. The fact that most of the threshing is done in the header means that the threshing system of the combine can be slowed down to avoid grain damage, worst case scenario is over ripe soft wheat.
With combine engine speed at idle, engage the header drive and then the combine separator, causing the combine separator and the header to engage at the same time, reducing the snatch in the header drive line.
The CVS and XCV range of headers are equipped with a variable speed belt drive system enabling the operator to adjust the rotor speed using a cab mounted switch. The RSD the pulleys are swapped to give a different ratio.
You adjust the height of the crop deflector according to the height of the crop and then lower the whole header so that the crop gently brushes underneath the crop deflector.
The up-wards rotation of the rotor tends to kick rocks out in front rather than picking them up.
The rotating rotor mounted in the front of the header combs through the crop feeding the heads back into the keyhole area of the stripping finger where the grain is stripped from the head and thrown backwards into the header. The majority straw remains standing whilst the combine processes predominantly grain.
There is enough foreign material such as leaf and straw to enable it to feed up into the combine.
85% of the grain is threshed in the header, it will be necessary to set the combine a little differently in order to attain the normal 50 to 100% capacity increase associated with a Shelbourne header.
The stripping fingers strip a little of the leaf material but leave behind virtually all of the stem so that the harvesting operation is not slowed down and there is enough of the weed left in the field to enable a post harvest herbicide application to succeed.
