Dual Wheel Systems

In the current market there are various types of dual wheel systems available, which means a system whereby an extra wheel is mounted next to the existing tractor wheel. The increasingly heavy combinations of tractors and agricultural tools are faced with many problems under poor terrain circumstances. A dual wheel system can offer the solution. Although the current trend is increasingly towards wider tyres, the use of a dual wheel system still offers a practical and economical solution. The advantages of mounting a wheel next to the existing tractor wheel include:

Greater tensile strength
Less rutting or damage to the ground structure
Lower fuel consumption
Less slip and therefore less tyre wear

Molcon Dual Wheels: star system

In 1950, Pieter Krijn Mol, the father of various members of the current senior management, developed a star system for mounting a second wheel next to the existing tractor wheel. This universal quick release system for dual wheels was patented and became an international success. The star system is still used as the perfect solution for tractors between 50 and 200 hp. With the star system, a star with levers is welded into a bare rim and the levers can be hooked onto the existing tractor wheel in direct assembly or in an all-position ring. The entire unit is then tightened with a spindle. The advantages of the Molcon dual wheel system include:

Superfast mounting and removal
Universal system, depends only on the tyre size
No loose parts or hooks and eyes
Flexible system always adaptable to the original rim

Clamp-on dual wheels

The clamp-on dual wheel system is especially for heavy tractors between 100 and 250 hp and loaders. With the clamp-on system, a cylinder is placed in the existing tractor wheel. The cylinder has a rim for the dual wheel tyre. In this rim, there is a system with threaded rods for clamping the unit together. The nuts of the existing tractor wheel are replaced by eye nuts into which a hook is inserted with a threaded rod that connects the two halves. At the end of the threaded rod there is a quick-lock that can be fixed after clamping on by means of a dowel pin. The advantages of the clamp-on system include:

Maximum ground protection
Better traction = less fuel consumption
Greater stability = increased safety
Lower tyre pressure = driving comfort and larger “footprint”
Prevents rapid tyre wear

Cylinder couplings

With the KN cylinder coupling, a double wheel can be mounted quickly and with only 1 spindle. Extremely suitable for connecting two narrow in-row cultivation wheels at the desired spacing, two wide wheels, or a narrow wheel alongside the wide original tractor wheel. With its toothed cylinders, this system is built for the most demanding applications and is suitable for tractors with up to 600 HP. It is fully compatible with our Masterfit and Budget Pro demountable wheels.

Super-fast mounting requiring less manpower and the use of just a single spindle
Fits together in any position
Various intervals possible
Highly suitable for in-row cultivation
