Power is transferred to the rotors using a heavy-duty driveline with greaseable universal joints that ensure direct and even power transfer in all operating conditions. The driveline is protected with an overload clutch for increased reliability and durability should the machine encounter an obstacle or become overloaded.

To ensure excellent, long-lasting operation, the pivoting points are incorporated in the cast housing. The driveline is equipped with flexible joints for easy rotation of the tedder in all positions. These joints are easily accessible for greasing and maintenance but remain clean and free from crop build up

Two vital adjustments for excellent tedding are rotor angle and rotor height. Rotor angle adjustments are made by altering the position of the rotor ground wheels. Operators have a choice of 5 positions to set the rotor angle (from 10° to 17°), eliminating the risk of contamination and resulting in tedding suited to specific crop types and conditions.

• Rotor height is easily adjusted on mounted tedders by reducing or extending the length of the top link. While on trailed machines, the rotor height is adjusted by turning the simple wind handle.
• Thanks to the large circumference of the rotors, they operate at relatively low revolutions. The wide arc and slower rotations offers more time for both the crop to be lifted and the hook tines to release the crop. This maximises crop lift and allows for an even spread across a greater distance.
• Crop Deflection Plates stop the crop from becoming entangled in the rotor wheels by diverting the crop to the rear of the machine

Thanks to the angle and shape of the 9mm, heavy-duty, tensile-steel hook tine, the crop is distributed high, evenly and far behind the machine to leave the ground clean and provide a consistent spread of crop for drying.

• The hook tine performs well when tedding a wet, heavy crop as the tine grips all the crop, spreading it further away so that it lands on top of the drier crop, improving fodder quality.
• The profile of the hook tine avoids damaging the ground and prevents soil contamination to the crop.
• The flexibility of the tines enable the rotor position to be adjusted to a more aggressive forward angle for improved tedding, which results in less damage to the ground, less contamination to the crop and faster regrowth of grass

The McHale ProPel T8-1020 is equipped with a trailed chassis which acts as a carrier frame when in transport. During field operation, the chassis runs on the wide tyres in front of the rotors in order to support the rotors. This also allows for the rotors to operate independently without being hindered by raised wheels or other road transport mechanisms which are not required in the field.
