The U 436 multi-purpose cultivator is a prime example of ploughless cultivation. Unlike ploughs, this machine not only loosens the deeper layers of soil, but also brings the topsoil to a condition suitable for sowing. Its greatest advantage lies in its flexibility and versatility. The sturdy frame is rigid enough for intensive use by high-powered tractors. Complete tillage can be achieved with just one use. This is due to the 3 different components:
- Tines
- 3 main components: 3 mowers
- 3 types of tillage rollers

The tines are responsible for working the medium and deeper soil layers and for returning crop residues to the soil. The discs chop up the residue and level the surface, while the cultivator roller at the rear of the machine closes the soil surface.

The 3-row layout allows for more versatile and efficient cultivation and has a positive effect on fuel consumption.

Insurance
The cultivator is available with 2 types of insurance: spring and Non-Stop spiral spring.

Caps
The hoes are designed to maximise ground penetration while keeping the required traction force at a low level. Each grab reacts individually to obstacles thanks to the insurance. Like Rolmako machines in general, this model is highly configurable. The tines are available in different versions to suit individual needs. They are arranged in 3 rows and can cultivate soil from 5 cm to 30 cm. The distance between each row is 80 cm.

The tines are made in Germany using a special heat treatment process. Thanks to the quality steel, a long service life can be expected.

Frame
The main frame of the machine is made of 140x140x8 mm steel profile. It is characterised by a high rigidity and a high weight, which makes it resistant to heavy tractors and capable of fast and aggressive cultivation.
