Small specialized disc harrow

The U 645 is a harrow designed for use in vineyards and orchards. Lightweight and compact, it enables operation in confined spaces where larger machines cannot maneuver. The harrow's working elements turn the soil, eliminating weeds, stubble, and plant residues. The discs are positioned at an optimal angle for increased speed and reduced fuel consumption. The disc harrow is suitable for superficial and delicate cultivation. Independent discs and rubber shock absorption make the machine adaptable for stony soils. It is an excellent tool for soil preparation in vineyards, promoting oxygenation and the mixing of organic matter.




The ideal instrument for vineyard and orchard operations

The U 645 harrow incorporates all the features of larger disc harrows, such as the rubber shock absorber, angle of attack, and disc bearing. This machine's design is based on a compact disc harrow, tailored in hitch category and size to work with orchard tractors. The U 645 vineyard and orchard harrow ensures excellent penetration, even on compacted or hard soils, due to the orientation of the working elements and high pressure on the disc. It features a high structural strength frame with adjustable width. Independent toothed discs with rubber shock absorbers provide maximum adaptation to the ground profile, even in stony conditions.










Designed for compatibility with orchard tractors

Non-stop disc harrows for vineyards and arboretums, suitable for tractors from 40 to 100 HP, available in widths from 1.25 to 2.00 m, capable of operating at a maximum depth of 15 cm. Large clearance for optimal management of weeds or pruning residues. Designed for professional users performing inter-row work in heavy, compacted, or hard soil. Ideal for covering fertilizer. The U 645 disc harrow for vineyards and orchards can be aggregated with tractors of hitch category I and II.

Machine construction



1. Three-point linkage tower

The three-point hitch system of the disc harrow is engineered for coupling with tractors that comply with categories I and II..

2. Working elements

Standard harrow disc with aggressive tine: 510 mm, optional 560 mm. Standard thickness: 4 mm, optional 5 mm and 6 mm. Other disc shapes available (smooth, fine-tooth, ALFA disc).

3. Bearing of working discs

Disc hub requiring maintenance or maintenance-free, lubricated and sealed for the entire service life.

4. PREMIUM working elements

The machine employs internationally recognized soil cultivation systems, utilizing readily available high-quality components from specialized suppliers.

5. Rubber shock absorbers

Rubber spring elements allow the optimal adjustment of the concave discs to the contours of the cultivated soil. This ensures the safety of the disc harrow frame and absolute maintenance-free overload protection while maintaining the preset working depth.

6. Tillage roller

To cultivate the soil effectively, selecting the appropriate tillage roller is essential. The choice depends on the soil type and the desired outcome. Each roller variant is designed for specific working conditions.

7. Roller cleaning system

Cleaning components constructed from wear-resistant, hardened boron steel.

8. Mechanical depth adjustment

The standard mechanical working depth adjustment is user-friendly and requires no additional tools.

9. Solid oversized machine frame

The solid frame construction is the most critical element of the cultivation machine. The substantial amount of steel used in its construction makes these robust tools capable of utilizing the high power of modern agricultural tractors, ensuring many years of operation on the farm.

10. Quality steel

Achieving a high-quality final product necessitates the use of superior metallurgical materials; therefore, in manufacturing the agricultural machine frame, we utilize fine-grained Swedish steels S500MC and S700MC.

11. Laser processing of sheets, tubes, and profiles

The application of laser techniques in the production of agricultural machinery facilitates precise cutting in high-quality, hard sheets, where conventional chip drilling methods are challenging and costly.

12. Steel shot blasting and powder coating

Proper preparation of machine parts combined with powder coating ensures a durable and robust coating. Additional maintenance and complicated care are unnecessary.
