Pottinger’s Flowtast plastic skid is now an option on its 7.7 to 8.4 metre, Top 842 C twin rotor rake.
Previewed at last year’s Agritechnica show, the sickle-shaped alternative to wheels has subsequently been undergoing field testing.
The company says while keeping tines close to the ground, it has found situations where a wheeled chassis has reached its limits, especially on wet, peaty soils which can result in deep wheel marks.
To combat this issue, the company has developed its Flowtast system, which it says offers ground tracking abilities, not possible with wheels, especially where ruts and hollows are concerned. Following testing in the UK this year across silage, hay, lucerne and straw, the manufacturer says it is now confident in its performance and is offering it as an option for next season’s rakes.
Key to the skid is an abrasion resistant plastic, PE 1000, the same as it uses in its plastic mouldboards, arranged in five replaceable pads, each 15mm thick. The company says the large area of contact improves load-bearing capacity on wet soils, with a hydraulic suspension system taking some of the Top 842 C rotor unit’s weight, leading to a ground pressure of about 200kg spread across it.
The skid is installed close to the tines, allowing the full raking arc to be supported, while tracking the ground. In addition, the sickle shape bar also allows for sideways movements.
A jockey wheel mounted in front of the rotor is an additional option for very undulating ground.
Price for the Flowtast option, including the skid and suspension setup is £4,343.
