Applicators - Fan Jet Twin Plus And Duo Plus

These models use a rotary feed mechanism instead of gravity feed feed onto the discs. Fluted feed rolls are driven by reliable electric motors and the choice of feed roll and speed of rotation determines the application rate. The VS-2 control can be used without a speed input as a low cost manual control, or with a speed input provides economic speed proportionate metering, or using the i-CON GPS based control, rates are automatically controlled in proportion to forward speed for ultimate accuracy, and can apply PF variable rate application working from field maps, + an option of tractor ISOBUS control. Rotary feed also allows very low application rates to be used for multiple low rate top-ups, for example when blight spraying potatoes. The two models are very similar, and essentially the only difference is the disc motor.

The Twin PLUS uses 2 x standard disc motors used on Fan Jet Pro and Fan Jet Twin models – due to the lower power requirement (40A) this model is ideal to use with UTV's (utility vehicles) as well as crop sprayers and tractors, and can spread a large, dense slug pellet typically from 20m up to a maximum of 30 metres.

The Duo PLUS is essentially the same except the disc motors are larger and more powerful, spinning at up to 1000rpm faster - it is ideal to use with self propelled sprayers and to fit to the front linkage of tractors, and can spread a large, dense slug pellet typically from 24m up to a maximum of 36 metres.

Please Note. Due to the increased power requirement (min 60A) the Duo PLUS is not recommended for UTV use unless high capacity alternators are fitted - please note that disc height will still be a limiting factor regarding the maximum spread from a UTV.

Both the Twin PLUS and Duo PLUS models use 2 Fan Jets, handed left and right, which are used together but have individual LH and RH controls allowing either side to be shut off independently. They can be mounted on the optional front mounting beam 1.9m apart, and the discs and disc motor are reversed on one machine to give contra-rotating discs. Chassis, motors, feed mechanism, controls and discs are specific to these models. Hopper capacity each side is 65 litres giving a total capacity of 130 litres (100kgs slug pellets). An option of larger hoppers is available.

Spread Widths

For maximum width, we recommend a minimum disc height of 2m from the ground or crop canopy, and calm conditions.
Slug Pellets.It can spread a large, dense, wet extruded slug pellet up to approximately 30 (Twin PLUS) or 36 (Duo PLUS) metres in total. Each machine spreads from the centreline of the vehicle, up to 15m or 18m each side to give a combined total of up to 30m or 36m.

Fitting

We recommend front mounting direct to the chassis of self propelled sprayers or tractor front linkage, using the optional front mounting beam to position the Fan Jets 1.9m apart centre to centre.
A strong rigid mounting point is required to attach the beam. A strong rigid mounting is required.

As a cost option we offer a hydraulic raise and lower front linkage to fit to the front of John Deere self propelled sprayers. Lower the linkage for safe filling and calibration, and raise to the working height of 2m for maximum spread. Please enquire for details, or for other makes of sprayer.

(Many other sprayer manufacturers offer their own versions of hydraulic linkage to suit the Twin or Duo, for example Sands, Agrifac, Bateman, Househam, Knights).


Electric Controls - Click on the image below to enlarge:

Supplied as standard the VS-2 control can be used either as a lower cost manual rate adjustment, non speed proportionate control, OR with a an optional speed input, it will provide economic automatic speed proportionate rate application in line with forward speed.
Optional i-CON controls. A very comprehensive GPS based system for automatic speed proportionate rate application plus the ability to use fully automatic PF variable rates if required (+ option of tractor ISOBUS control).
Both control systems have independent LH and RH feed control with instant start and stop of spreading, and variable disc speed with + monitoring and alarms.





Spreading Features

Powerful 12volt disc motors drive the discs at high speeds. These require sufficient electrical power to work correctly, especially the Duo PLUS. An audio-visual alarm warns of low power or disc motor failure.
The contra-rotating discs stainless steel discs are handed left and right, and each has 4 long stainless steel vanes running from the centre of the disc to the outside. Pellets are collected gently in the centre, then accelerated along the vane with less breakage to give a wider and more even spread of intact pellets with greater efficacy in the field and greater resistance to weathering.
Product is metered via fluted feed rolls onto the discs which are deliberately biased to spread to the left and right respectively. The choice of feed roll, and speed of rotation determines the application rate. The VS-2 control has 36 equally spaced motor speeds and allows on-the-move manual rate change and an option of the i-CON control will give fully automatic stepless speed proportionate output, and could be linked to field maps for precision farming variable rate application working from a field map. Independent LH and RH control of the feed motors give instant, positive start and stop to spreading.
A Calibration Chute is supplied as standard to aid safe and accurate rate setting.

Width and Headland Control

Independent left and right hand control is used to shut one side off for short work and as a headland control.
Variable disc speed control is used as the primary method of spread width setting and is ideal to use as headland control, simply dial down the disc speed as required.
Stepless spread bias adjustment provides adjustment of the throw of product to the left or right to fine tune the pattern, and can also be used as a headland control. Simply rotate the complete feed mechanism in the direction where you want more product.
