3. The mower blade assembly of claim 1 further comprising:

a fastener opening provided in the mounting tab; and

a through hole provided in the other of the main body and the blade insert and in communication with the mounting pocket.

4. The mower blade assembly of claim 3 , wherein, when the blade insert is in the operable position, the fastener opening and the through hole are axially aligned.

5. The mower blade assembly of claim 4 , wherein the fastener opening is a threaded opening, and further comprising a threaded fastener configured to extend through the through hole and engage the threaded opening when the blade insert is in the operable position to secure the blade insert in the operable position.

6. The mower blade assembly of claim 5 further comprising a lock washer configured to be compressed between a face of the other of the main body and the blade insert and a head of the threaded fastener when the blade insert is in the operable position.

7. The mower blade assembly of claim 1 , wherein the mounting tab includes an orientation key and the mounting pocket includes a correspondingly shaped and sized notch to receive the orientation key when the blade insert is in the operable position.

8. A mower comprising:

a mower deck including a rotating shaft rotatably coupled to the mower deck; and

a mower blade assembly comprising:

a main body removably coupled to the rotating shaft; and

a blade insert removably attachable to the main body between an operable position and a removed position, with the main body and blade insert presenting respective end faces with matching outer edges in the operable position,

wherein one of the main body and the blade insert includes a mounting tab and the other of the main body and the blade insert includes a mounting pocket sized and shaped to receive the mounting tab when the blade insert is in the operable position, in which the other of the main body and the blade insert is slid onto the mounting tab until the end face of the blade insert abuts the end face of the main body and restricts further sliding beyond the operable position,

wherein the mounting pocket includes an opening provided in the end face of the other of the main body and the blade insert for receiving the mounting tab, the opening being defined by a closed perimeter provided in the end face of the other of the main body and the blade insert.

9. The mower of claim 8 , wherein the mower blade assembly further comprises a second blade insert removably attachable to the main body between an operable position and a removed position, wherein the main body includes a pair of distal ends extending away from a central portion that couples to the rotating shaft, wherein the blade insert is removably attachable to a first distal end of the pair of distal ends, and wherein the second blade insert is removably attachable to a second distal end of the pair of distal ends.

10. The mower of claim 8 , wherein the mower blade assembly further comprises:

a fastener opening provided in the mounting tab; and

a through hole provided in the other of the main body and the blade insert and in communication with the mounting pocket.

11. The mower of claim 10 , wherein, when the blade insert is in the operable position, the fastener opening and the through hole are axially aligned.

12. The mower of claim 11 , wherein the fastener opening is a threaded opening, and wherein the mower blade assembly further comprises a threaded fastener configured to extend through the through hole and engage the threaded opening when the blade insert is in the operable position to secure the blade insert in the operable position.

13. The mower of claim 12 , wherein the mower blade assembly further comprises a lock washer configured to be compressed between a face of the other of the main body and the blade insert and a head of the threaded fastener when the blade insert is in the operable position.

14. The mower of claim 12 , wherein the mounting tab includes an orientation key and the mounting pocket includes a correspondingly shaped and sized notch to receive the orientation key when the blade insert is in the operable position.

15. A method of replacing a blade insert of a mower blade, the method comprising:

slidably coupling the blade insert to a main body of the mower blade, wherein the main body and the blade insert present respective end faces with matching outer edges in an operable position, wherein one of the main body and the blade insert includes a mounting tab and the other of the main body and the blade insert includes a mounting pocket sized and shaped to receive the mounting tab, and wherein slidably coupling the blade insert to the main body includes sliding the mounting tab through an opening provided in the end face of the other of the main body and the blade insert and receiving the mounting tab in the mounting pocket, the opening being defined by a closed perimeter provided in the end face of the other of the main body and the blade insert,

wherein slidably coupling the blade insert to the main body includes sliding the other one of the main body and the blade insert onto the mounting tab until the end face of the blade insert abuts the end face of the main body and restricts further sliding beyond the operable position; and

removably securing the blade insert to the main body.

16. The method of claim 15 further comprising slidably coupling a second blade insert to the main body.

17. The method of claim 15 further comprising, during the slidably coupling the blade insert to the main body, axially aligning a fastener hole provided in the mounting tab with a through hole provided in the other of the main body and the blade insert.

18. The method of claim 17 further comprising extending a fastener through the through hole and engaging the fastener with the fastener hole.

19. The method of claim 18 , wherein the fastener is a threaded bolt, and wherein the fastener hole is a threaded hole, the method further comprising threading the threaded bolt into the threaded hole to thereby removably secure the blade insert to the main body.

20. The method of claim 19 , further comprising

unthreading the threaded bolt from the threaded hole;

slidably decoupling the blade insert from the main body;

slidably coupling a replacement blade insert to the main body; and

threading the threaded bolt into the threaded hole to thereby removably secure the replacement blade insert to the main body.
