Figure 7-2 • Charge the battery with a 12-volt battery charger at a MAXIMUM rate of 10 amps. Servicing Electrical System A fuse is installed to protect the tractor's electrical system from damage caused by excessive amperage. Always use the same capacity fuse for replacement. If the electrical system does not function, check for a blown fuse. If you have a recurring problem with blown fuses, have the tractor's electrical system checked by your Cub Cadet Service Dealer. Relays and Switches There are several safety switches in the electrical system. If a function of the safety interlock system described earlier is not functioning properly, have the electrical system checked by your Cub Cadet Service Dealer. Deck Removal Remove the mower deck from the tractor as follows: 1. Move the tractor to a level surface, disengage the PTO, stop the engine, and set the parking brake. 2.

Remove the 'V' belt from the PTO pulley, located on the bottom of the engine, using one of the following two methods. WARNING! The muffler at the rear of the tractor may be extremely hot, and could cause serious burns. Use extreme caution when near the muffler.
