The Profi-flex Wheel is GKN Wheels and Structures’ manually adjustable variable track wheel and a well proven industry standard.

A key trend within the agricultural market in recent years has been the move towards bigger farms, meaning that tractors spend more time on the road with a need to travel faster. There is also a need for a greater frequency of track adjustments to suit the needs of varying crops. These changing demands placed on vehicles produce additional stresses on wheels. GKN Wheels and Structures’ Profi-flex Wheel incorporates many design features that make it the most capable, adjustable wheel on the market today. The Profiflex wheel features 16 different track positions, with 15mm between each, meaning a more accurate position can be achieved when planting multiple crops or moving from fieldto-field. The variable width also lends itself to situations where more steering ability or traction may be required.

The Profi-flex Wheel is used globally by major agricultural equipment manufacturers. The component tolerances have been developed to allow all adjustable track wheels to be suitable for operations at speeds of up to 50kph.

Key to performance is a continuously welded flange ring which joins the centre disc to the wheel rim, creating a constant cross section flange ring ensuring an even distribution of loads between the rim and disc, which in turn minimises stress on the wheel. In addition, the flange has a very flat profile, giving an excellent surface for bolt location and making it easy to maintain the preloaded torque.

The Profi-flex Wheel from GKN has proven so successful in matching the current requirements of the agricultural market that more than 100,000 a year are now being sold.
