Default Cub Cadet 782 not starting

I have finally found my dream Cub, a 782! It is a clean machine. It is an 1981 model with an IH serial number. It also has the original hub caps, and even has the series II motor. My problem with it is that it doesn’t attempt to start. When I bought it, it ran, but it sat out at an auction site for a few weeks recently. I was maybe thinking one of the safety switches was bad, but I haven’t had time to mess with it. What common problems do these Cubs have? Is there some troubleshooting I should do first? I’m excited!

We need more info:
Does it turn over but not start?
You say the lights "click on" do you mean they turn on when the Ign switch is in the light position?
is the PTO switch in the "OFF" position?
Is the brake/clutch pedal pushed fully in?
Are sitting on the seat?
Have you wiggled the wires on the back of the IGN switch?
Have you checked to see if your battery is good?
Are BOTH battery terminals clean and tight? ON BOTH ENDS?
Report back.

I have not had time to look at it this morning, but I did last night. The tractor does not attempt to start. The lights do click on when in the accessory position. The PTO switch was off when I did, I was sitting in the seat with the brake/clutch pedal pushed in. Nothing happened when I did that. When I have time to, I'll check the battery and wiggle the ignition switch. I will report back.

Default CC 782 not starting

Have you tried touching a (positive) battery jumper cable directly to the (positive) starter terminal to see if it turns over? Maybe the solenoid is bad...

Okay thanks, I’ll check that out! It might be the weekend before I find time to really mess with the tractor. I’ll respond as I figure stuff out.

I did some slight tinkering this morning, but nothing much. I have checked the battery and the cables, those a good. I also wiggled the wires on the ignition switch, and nothing happened from that. I also checked the seat safety switch, and that has been bypassed. I went ahead also and bypasses the neutral safety switch as well. Those two switches are functioning as well. What do I need to test now? Should I check the ignition switch and starter solenoid next? Thanks!

There are 2 wiring diagrams for the 782's,-- early and late models.
Someone will direct you to them, I'm leaning toward your 782 having the later diagram, just so you know,so you don't take the wrong fork in the road.
Both diagrams are not that complicated, ain't no computers on those good ol machines!
they are simple.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
