Mahindra Medium Duty UM Rotavator

Mahindra Medium Duty UM Rotavator

The Mahindra Medium Duty UM Rotavator, a part of our lightweight series Rotary Tiller range, is meticulously engineered to deliver high-performance results in medium soils, regardless of dry or wet conditions. Its lightweight yet robust design offers a comprehensive solution, perfectly meeting the tilling requirements of forward-thinking farmers, making it an indispensable tool for modern agricultural practices.


Helix Spiral configuration rotor

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.

Duo Cone Sealing System

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.

Anti Clogging System

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

Powerful Side gear Train

MD Tiller also feature 3-gear powertrain assembly at the side, which ensure 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 stub axle shall get distributed on 3 pin topology over the side plates.

Optimum rotor rpms

To achieve a finer tilth, an extra-powerful gearbox having (13X25) bevel gears are fitted, reaching 238 rpm.

Sturdy Gears and shafts

Straight Bevel deployment in 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 gear drive cool. Thus, minimize need of repairs and maintenance.

Spring Adjustable Levelling Bonnets

Working at field operations, new handle design of spring adjuster rod ensure soil levelling and easy to adjust.

Stable Hitch Pyramid

Working on light & medium soil ground, the new strong top mast hitch pyramid structure provide greater strength. This is designed to have quick hitch adaptability.

Strong and dust-free transmission covers

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 push in the O-ring inside, providing a much more effective seal to protect gears from dust and water ingress.
