What is DynaTrac?

How does the DynaTrac guidance interface position all implement accurately and repeatably?

First, DynaTrac consists of a module at the rear of the tractor which shifts laterally to adjust the position of the rear implement. It does that constantly to warrant that the implement remains on the same GPS guidance path (A- B line) as the tractor. Some call it a shifter.

DynaTrac 3-point version

Secondly, DynaTrac goes for a range of universal guidance interfaces also called side-shift hitches.

DynaTrac

  • DynaTrac exists in several 3-point versions which allows to be confident that there will always be the right DynaTrac for a type of tractors and implements. Indeed, each version fits a wide range of tractor rear hitches and farm implements. It can receive 3-point, 2-point and pulled implement to offer versatility. DynaTrac 3-point range is composed of:
    • DynaTrac Compact: weights 400kg and carry equipment up to 1500 kg. Travel range is 30cm. It is PTO compatible. Cat 2 connection on implement side.
    • DynaTrac Premium: weights 700 kg and carry equipment up to 4500 kg. Travel range is 50cm. It is not PTO compatible. Cat 3N connection on implement side.
    • DynaTrac Premium+: weights 800 kg and carry equipment up to 5000 kg. Travel range is 30cm. It is PTO compatible. Adjustable Cat 3N or 3W connection on implement side.
    • DynaTrac Ultima: weights 1500 kg and carry equipment up to 7500 kg. Travel range is 50cm. It is PTO compatible. Cat 3N pr 4N connection on implement side.

In the 3-point versions, DynaTrac replicates a tractor rear hitch with all the well-known benefits of this design for easily connecting implement and adjusting their position. On top of that, it adds the shifting feature which allows to position it accurately making it a smart rear hitch. It is also called a Smart Quick Coupler. This is the perfect equipment for any farmer willing to implement precision farming.

DynaTrac Classic pull-type version

 

  • DynaTrac Classic focuses on pull type implements like planters for corn or soybean. It fits directly by replacing the head of the planter like on the John Deere 1770 & 1775 NT; 1790/95, 7200 planters for which it was originally designed. It also fits White planters, Case IH 1250 and 2150 If it cannot match straight, a range of adaptors is available to connect it to most planters in the market (Horsch, Kinze, John Deere DB planters, etc.) as well as Nitrogen side dress Bar like Blu jet or Fast for instance.

 

Why is it, truly, the best guidance solution for a farm?

Switching implement easily and quickly

First, DynaTrac offers 3-point connection. Consequently, the guided implement can change easily and quickly. With other implement guidance systems like steering discs (or steering blades) specifically fitted to the rear of the implement, it consumes much more time, tediously. Being usable with all implements, it makes precision possible for each field operation. As a benefit, it pays off faster as each path leverages accuracy for better yield or less crop damage.

Less need for correction, more accuracy

In addition, DynaTrac 3-point range incorporates a patented design giving the option to work with the lower links of the DynaTrac in float position. It makes it smoother to steer. Benefits lie in more accuracy and less need for position correction. Indeed, the system not being rigid like other side shift hitches in the market, it does not push the tractor on one side when the implement shifts in the other direction. There is no more interference between the tractor guidance system and the implement guidance system. Many customers were enthusiastic about it when they saw it operating in their field so efficiently.

Different uses of DynaTrac

An extra benefit of the float mode of the DynaTrac arms is that when implement position adjusts, the DynaTrac guidance interface changes the direction of the head of the implement when shifting (see it here in 3D video: https://www.youtube.com/watch?v=jBKOUAoEwPQ&t=36s). Consequently, the implement always moves forward and never laterally. This avoids damaging the working elements of the implement like rigid shifting interfaces do when they push the implement on the side. This is particularly beneficial for planters which working elements are expensive and sensitive. That is why planter manufacturers do not want rigid guidance interfaces to be used with their planters. It is also an issue for row crop cultivators. Many row crop cultivator manufacturers pay attention and spend money to reinforce the support of working elements to absorb the side loads generated by rigid shifting interfaces. This issue disappears with a Laforge DynaTrac.

A rigid shifting interface can also be an issue when working with ground engaging or heavy implements (bed ploughs, strip-till, etc.) as this would bend the shanks of the implement or move the tractor but not the implement, generating extra inaccuracies.  All these issues settle with the float position of the DynaTrac guidance interface when used with 3-point implements.

Arms on float or locked, at your convenience

Of course, the lower arms of the DynaTrac can get locked when needed. It can be done automatically (in headland management settings) with 3-point implements when lifted for U-turn to ensure that it centers and when driving on the road. This is also the case to pull implements which have a pivot point integrated in the tongue.

Complementary to the lateral float option explained above, the DynaTrac 3-point range also offer a vertical float feature. This allows to have the implement weight on the tractor when needed to improve steering authority and have a better driving control. It also guarantees that the implement will always be parallel to the ground. For instance, in a field with slopes, the tractor tires compress more on one side. Without vertical float function on the guidance interface, the implement will not work at a homogenous depth which is detrimental at planting for example.

How is DynaTrac steered to ensure high accuracy positioning of the implement?

A key component to operate DynaTrac is the positioning system. Several solutions exist to adjust DynaTrac position (hence also implement) in real time:

  • GPS guidance systems with RTK signal. Main solutions in the market (that we are aware of) are:
    • Active Implement Guidance from John Deere
    • True Tracker from Trimble
    • Smart Steer from Homburg

GPS guidance allows to guide all kind of implements without restrictions.

  • Camera guidance: very developed to guide row crop cultivators (also known as mechanical weeders). Laforge offers a Vision kit with camera
  • guidance as an option with DynaTrac
  • Ultrasonic guidance: interesting to guide on beds like for potatoes or orchard when GPS signal is not good
  • Sensors: sometimes used in corn when high enough. Can be combined with camera or ultrasonic guidance.
