## Abstract

A machine with a tool rotor (100) comprising at least two hydraulic motors (112, 122), which are connected to each other and may be connected via at least one inlet conduit (201, 203,) and at least one outlet conduit (202, 204) with a hydraulic source of a machine (200) that carries and/or tows the machine (200) (100) and each hydraulic motor is respectively connected, via a taper roller bearing (111, 123) that supports a respective shaft (104, 107), with a belt drive (102, 103) that drives a shaft (108) of a tool rotor respectively connected to one end of the shaft (108) of the tool rotor (101). At least one distributor is interposed between the hydraulic motors, and remote electronic adjustment of displacement/volume of at least one hydraulic motor is controlled.

## Claims

### Claim 1

A machine with a tool rotor comprising at least two hydraulic motors, which are connected to each other and may be connected via at least one inlet conduit and at least one outlet conduit with a hydraulic source of a machine that carries and/or tows the machine with the tool rotor, and each hydraulic motor is respectively connected, via a taper roller bearing each supporting a respective shaft, with a belt drive that drives a shaft of the tool rotor respectively connected to one end of the shaft of the tool rotor, wherein at least one distributor is interposed between the at least two hydraulic motors, and remote electronic adjustment of displacement/volume of at least one hydraulic motor is controlled.

### Claim 2 (depends on 1)

The machine with a tool rotor as claimed in claim 1, wherein the at least one distributor is the at least one hydraulic motor.

### Claim 3 (depends on 1)

The machine with the tool rotor as claimed in claim 1, wherein the at least one distributor is integrated in at least one hydraulic motor.

### Claim 4 (depends on 1)

The machine with the tool rotor as claimed in claim 1, wherein the displacement/volume of the at least one hydraulic motor that is not remotely controlled is mechanically adjustable.

### Claim 5 (depends on 1)

The machine with the tool rotor as claimed in claim 1, wherein the at least two hydraulic motors have a port for an inlet conduit and an outlet conduit.
