The helix spiral blade configuration rotor can accommodate 2 types of blades, C-shaped and L-shaped, designed for ultimate soil finishing and working crop residue into the ground. Blades are arranged helically around the rotor, resulting in the blades entering the soil progressively and thus reducing power draw. Also helps achieve finer tilth of soil. Specially designed for high performance in light and medium soils in both dry and wet soil conditions such as puddling.

The Duo-Cone sealing system guarantees reliability without the need for maintenance. You can achieve at least 50% longer life from the Duo-Cone system than standard sealing systems in the most demanding working environments. The sealing system is completely waterproof or “amphibious” allowing the rotor and bearing to run in its own oil supply, this allows the rotor to work and be reliable in the dustiest of environments or even work immersed in water and yet the seals will still prevent water and dust ingress into the rotor and hubs.

A rather attractive optional extra is the anti-clogging system: a sheet metal membrane that stops clinging/wet soil from clogging up the machine.

HD Tiller also features a 3-gear powertrain assembly at the side, which ensures constant transmission with no loss of power. The side transmission has been designed in such a way that load surges acting due to tangential forces acting on the stub axle shall get distributed on 3 pin topology over the side plates.

Spiral bevel deployment in the gearbox that drives for high torque and high-speed operations. Since being the topology in right angle shaft orientation, also helps in drastic noise reduction. Smooth operation keeps the gear drive cool. Thus, minimising the need for repairs & maintenance.

The new strong levelling bonnets provide greater wear resistance while working on stony ground. Their Z shape means perfect soil levelling can be achieved in all conditions. They feature spring rods for adjusting the height with hand-holding unique brackets. Gearbox vibration can further be reduced by opting right combination of turn buckles, unique in the segment.

Working on stony & hard soil ground, the new strong box-type hitch pyramid structure provides greater strength. The front and rear plate keeps the hitch pyramid stable and increases strength.

UM tiller models feature a transmission cover made from CR sheets, which is much stronger than regular grey cast iron. The cover has a chamfer on the inside housing that pushes in the O-ring inside, providing a much more effective seal to protect gears from dust and water ingress.
