The power receiving component may receive power generated during rotation of a drive shaft, and generate torque and speed for rotating the rotatable shaft. Increasing the driving rotational speed of the drive shaft may increase a driven rotational speed of the rotatable shaft, and decreasing the driving rotational speed of the drive shaft may decrease the driven rotational speed of the rotatable shaft. ## Claims ### Claim 1 A paving machine, comprising: a screed assembly including a fixed screed and an extendable section disposed proximate an end of the fixed screed, wherein: the fixed screed comprises: a first drive shaft that extends through one or more portions of the fixed screed, and a second drive shaft that extends through the one or more portions of the fixed screed, the one or more portions of the fixed screed comprise one or more of a base screed or a fixed section, the extendable section comprises a driven shaft, a power transmitting component is coupled to the first drive shaft, and the power transmitting component is configured to generate power in response to rotation of the first drive shaft, for actuating the driven shaft. ### Claim 2 (depends on 1) The paving machine of claim 1, wherein a power receiving component is coupled to the driven shaft, and wherein the power receiving component is configured to receive the power generated by the power transmitting component, and output torque and speed, for rotating the driven shaft. ### Claim 3 (depends on 2) The paving machine of claim 2, wherein the power transmitting component is a pump, a motor, or a generator, and wherein the power receiving component is a pump, a motor, or a generator. ### Claim 4 (depends on 1) The paving machine of claim 1, wherein at least one vibrating component is attached to the second drive shaft, wherein at least one tamper component is attached to the first drive shaft, and wherein at least one vibrating component or at least one tamper component is attached to the driven shaft. ### Claim 5 (depends on 1) The paving machine of claim 1, wherein the power transmitting component is configured to generate power in response to rotation of the first drive shaft, for actuating an extendable cylinder. ### Claim 6 (depends on 1) The paving machine of claim 1, wherein the driven shaft is configured to rotate at approximately a same revolution per minute as the first drive shaft. ### Claim 7 (depends on 1) The paving machine of claim 1, wherein increasing a first rotational speed of the first drive shaft increases a second rotational speed of the driven shaft, and wherein decreasing the first rotational speed of the first drive shaft decreases the second rotational speed of the driven shaft. ### Claim 8 A screed assembly, comprising: a fixed screed comprising: a first drive shaft that extends through one or more portions of the fixed screed, and a second drive shaft that extends through the one or more portions of the fixed screed, wherein the one or more portions of the fixed screed comprise one or more of a base screed or a fixed section; an extendable section extending from a portion of the fixed screed, wherein the extendable section comprises a driven shaft; and a power transmitting component coupled to the first drive shaft, wherein the power transmitting component is configured to generate power during rotation of the first drive shaft, and wherein the power is configured to actuate the driven shaft. ### Claim 9 (depends on 8) The screed assembly of claim 8, wherein the power transmitting component is a pump, a motor, or a generator. ### Claim 10 (depends on 8) The screed assembly of claim 8, wherein a first vibrating component is attached to the first drive shaft and a second vibrating component is attached to the driven shaft. ### Claim 11 (depends on 8) The screed assembly of claim 8, wherein a first tamper component is attached to the first drive shaft and a second tamper component is attached to the driven shaft. ### Claim 12 (depends on 8) The screed assembly of claim 8, wherein the power is configured to actuate an extendable cylinder disposed in the extendable section of the screed assembly. ### Claim 13 (depends on 8) The screed assembly of claim 8, wherein the driven shaft is configured to rotate at approximately a same revolution per minute as the first drive shaft. ### Claim 14 (depends on 8) The screed assembly of claim 8, wherein increasing a first rotational speed of the first drive shaft increases a second rotational speed of the driven shaft, and wherein decreasing the first rotational speed of the first drive shaft decreases the second rotational speed of the driven shaft. ### Claim 15 An extendable section for a screed assembly, comprising: a rotatable shaft; and a power receiving component attached to the rotatable shaft, wherein the power receiving component is configured to receive power generated during rotation of a first drive shaft of a fixed screed, and generate torque and speed for rotating the rotatable shaft, wherein the fixed screed includes the first drive shaft and a second drive shaft, wherein the first drive shaft extends through one or more portions of the fixed screed, wherein the second drive shaft extends through the one or more portions of the fixed screed, wherein the one or more portions of the fixed screed include one or more of a base screed or a fixed section, wherein increasing a driving rotational speed of the first drive shaft increases a driven rotational speed of the rotatable shaft, and wherein decreasing the driving rotational speed of the first drive shaft decreases the driven rotational speed of the rotatable shaft. ### Claim 16 (depends on 15) The extendable section of claim 15, wherein the power receiving component is a pump, a motor, or a generator. ### Claim 17 (depends on 15) The extendable section of claim 15, wherein the rotatable shaft and the driving shaft rotate at approximately a same revolution per minute. ### Claim 18 (depends on 15) The extendable section of claim 15, wherein a tamper component is attached to the rotatable shaft. ### Claim 19 (depends on 15) The extendable section of claim 15, wherein a vibrating component is attached to the rotatable shaft. ### Claim 20 (depends on 15) The extendable section of claim 15, wherein the power receiving component is configured to actuate an extendable cylinder disposed in the extendable section.
