Question about Garden
I found out that the undercarriage of Victa riding mowers is the same as Murray mowers. Here is a website where you can download the pdf owners manual for a Murray. It should tell you how to change the belts. http://www.manualnguide.com/manual-get/10498/
I hope this helps.

You did not mention which belt has been damaged and there are two belts. From the parts list it would appear to be the blade drive belt you mean. The other belt seems pretty much protected by chassis members etc.
To change the drive belt (3, page 9 if we are on the same drawing) you would need to drop the whole mower housing Assembly (#54) which would involve removing all the bolts that attach the housing to the underside of the main mower housing suspension. the drawing is pretty complex but just qork your way through all the bolts and nuts that hold the mower housing assembly onto the frame work. There cannot be that many as Victa would have designed it to come off reasonably easily for just this purpose. Once off, the belt should fall off the lower pulley on the pulley stack. Reassembly is the reverse of what you did to remove the housing, just make sure that the belt remains around all the pulleys as you assemble the housing to the frame.
This is the parts list I found. Hope this is of some assistance to you:-

Follow the steps below;
1. Place the mower on a flat level surface.
2. Set the parking brake.
3. If the engine is hot, allow the exhaust system to cool down before attempting any maintenance.
4. Open the hood and remove the spark plug wire(s). Ground the spark plug wire (s) against the engine to prevent unintended starting before removing the belts.
5. Remove the cutting deck.
6. Lift the seat to gain access to the battery. Remove the battery. Note: When disconnecting the battery, always disconnect the black negative battery cable first then disconnect the red positive battery cable.
7. Look down through where the battery was located and you will see a large transaxle pulley. Loosen the large nut holding the transaxle pulley to the input shaft of the transaxle using a 7/16" socket.
8. Disconnect the spring from the anchor bolt on the left side of the tractor using a spring puller or a small piece of rope. This will relieve tension on the upper drive belt. Note: Orientation of left and right is determined from the operator's position in the seat.
9. Maneuver the upper (rear) belt from the transaxle pulley, and remove the belt from the mower.
10. Remove the belt guide from the variable speed pulley bracket using a 1/4" socket. Note: This is accessed through the battery compartment.
11. Lift the middle sheave slightly so the belt will clear the belt guide, and slip the belt off of the variable speed pulley.
12. Remove the belt keeper surrounding the engine pulley, using a 1/2" wrench.
13. Remove the bolt securing the crank shaft pulley using a 5/8" socket. Note: Tthe use of an air impact gun is recommended for removal purposes. If not, use a strap wrench to hold the crankshaft pulley while loosening the bolt.
14. When removing the engine pulley, take note of the orientation of the parts for reassembly (or take a picture). The pulley is secured by a bolt, lock washer, and a heavy flat washer. A spacer is positioned above the pulley on the crankshaft. The top edge radius matches the step on the crankshaft.
15. Remove the lower drive belt from the mower by pulling it towards the engine.
16. Belt installation is basically the reversal of the removal process. Install the new lower drive belt in place. Confirm the correct belt routing inside of all the belt keepers and through all the guide pins. Refer to your pictures taken before belt removal.
17. Apply a very small quantity of anti-seize compound to the engine crankshaft. This will help in the ease of the crankshaft removal in the future when needed. Note: DO NOT get any anti-seize compound on the bolts threads or in the bolt hole of the crankshaft.
18. Install the spacer with the rounded shoulder towards the engine.
19. While holding the spacer in place, install the crankshaft pulley. Be careful not to get any of the anti-seize compound on the belt or in the "V" of the pulley.
20. Install the crankshaft pulley bolt with the lock washer and heavy flat washer in place, with the lock washer to the bolt head and the heavy flat washer to the crankshaft pulley.
21. Using a torque wrench and tighten the crankshaft pulley bolt, to a torque of 37.5 - 50 foot pounds (51-68 Newton Meters).
22. Place the lower transmission belt into the upper "V" Pulley closest to the engine on the crankshaft pulley.
23. Lift the middle sheave slightly so the belt will clear the belt guide and slip the belt onto the variable speed pulley. Make sure the belt is fully seated in the belt grooves.
24. Re-install the belt keeper surrounding the engine pulley, using a 1/2" wrench.
25. Re-install the belt guide removed from the variable speed pulley bracket using a 1/4" socket.
26. Install the new upper drive belt into the upper sheave of the variable speed pulley and around the transaxle pulley. Make sure the belt is fully seated in the belt grooves.
27. Re-install the tension spring removed at the beginning using a spring puller or a small piece of rope and connect it to the anchor bolt on the left side of the tractor.
Tighten the large nut that secures the transaxle pulley to the input shaft of the transaxle. Use a torque wrench and torque to 10-15 foot pounds (13.6-20.3 Newton meters).
Because of the tension change with new belts, it is always recommended to check all drive adjustments after changing the drive belts.
The following procedure will be for the speed control linkage on the variable speed belt drive.
29. With the parking brake still engaged remove the cotter pin from the ferrule on the top side of the variable speed pulley bracket.
30. Disconnect the ferrule from the bracket. Note: If an adjustment is needed, there will be tension on the linkage, and the resulting friction will create resistance when sliding the ferrule out.
31. Thread the ferrule up or down the rod so that the post fits into the hole without any resistance.
Reinstall the cotter pin back through the hole in the ferrule on the top side of the variable speed pulley bracket.
The next procedure will be for the cruise control/parking brake adjustment on the variable speed belt drive.
33. With the parking brake still engaged, remove the cotter pin that secures the ferrule in the latch assembly. Next, disconnect the linkage from the latch assembly.
34. Thread the ferrule up or down the rod so that the post of the ferrule fits into the hole with out any resistance.
35. Secure the ferrule to the linkage using a new cotter pin and test the operation of the linkage.
36. Install the cutting deck back in place under the mower. Refer to your Operator's Manual in the "Service" section. Follow the cutting deck removal instructions in reverse order.
37. Install the battery. Connect the red positive battery cable to the positive battery terminal first. Next, connect the black negative battery cable to the negative battery terminal.
38. Reconnect the spark plug wires to the spark plugs.
39. Start the unit and check operation of all linkage and related safety features are operating correctly before returning the mower back into service.
I hope you find the above helpful.
