Typically, the Duo is mounted to self-propelled sprayers. However, the Duo can also be mounted to tractor front linkages and UTV’s. (UTV vehicles subject to electrical power output). It can be rear mounted, although not recommended, on sprayer booms due to its weight.

FAN JET DUO CONTROLS
TWO CONTROL OPTIONS
VS-2 CONTROL

The VS-2 offers a simple but effective manually operated electric control of both applicators.
Application rates are set by a combination of feed roller type and speed. Both can be changed on the move from the tractor seat using a simple dial control. With optional GPS, the VS-2 can regulate the speed of the feed motor according to forward speed to maintain the selected application rate. This option has an audio visual alarm to alert the operator of any malfunction.
- Switch 1 - feed motor on/off
- Switch 2 - feed motors left/right
- Switch 3 - feed motor speed range adjustment
- Middle dial - feed motor speed adjustment
- Switch 4 - spinning disc speed
- Right dial - disc motor speed control
- Includes alarm lights
TM (TWIN METERING) CONTROL

Supplied with a 4.3” colour touchscreen, the sophisticated TM controller has an intuitive layout; displaying the application rate, spread width and forward speed for each unit.
The TM provides cutting edge features such as section control and headland control. It is also capable of applying variable rates in conjunction with an uploaded precision farming map, clearly shown in real time on the control screen.
- 4.3” colour touchscreen
- 4 screens – home, parameters, details and mapping
- Forward-speed related metering with GPS
- Variable rate application (in conjunction with uploaded precision map)
- Records each job/field and stores in memory
The application rate is automatically controlled. The software can be programmed to record each job/field, allowing calibration settings and application rates to be ‘remembered’ for future use.

FITTING
Most commonly mounted to the chassis of self-propelled sprayers the Duo can also be fitted to a tractor front linkage or to a UTV. An optional front mounting beam positions the pair of Fan Jets 1.9m apart centre to centre.

Stocks recommend that the applicators are lowered for safe filling and emptying as well as the calibration of each applicator and then raised to a working height of 2m.
CALIBRATION HOPPER
An optional calibration aid, a steel chute is easily attached and collects and deflects the product being spread into a user provided bag for weighing during calibration checks. Supplied as standard with all TM models.
WATERPROOF COVERS
All Fan Jet models can be supplied with optional waterproof covers for use when out of work.

BUILT IN THE UK
Wisbech is still the home of Stocks Ag. All applicators are fabricated, assembled and painted in the Cambridgeshire factory. Precision assembly and quality control are paramount to the production process.
The R & D team work with both the factory and farmers to deliver a seeding solution that is fit for current farming practices.
