Default 1440 Safety Circuit Help Please
Stopped running a while back. Found melted, dirty wire from battery to ignition switch. Replaced ignition switch. Also have replaced PTO Switch, Brake Switch and Relay by battery. The Reverse Switch has broken it's mounting connection and is just dangling in open position. Engine will crank and start. Dies when I take my foot off the brake. I can power up PTO with brake on ok. Engine dies when PTO switch is released to the run position. Battery cables all clean, fuse ok. I checked the seat switches and according to my analysis they are OK.

Can anyone offer any suggestions?

So, you have the following parts new:
* Ignition Switch
* PTO Switch
* Brake Switch
* Wires in/around the Ignition Switch

Is that correct...??

Next, there are two Seat Switches. One switch (normally open) with BLK & PUR wires, is a safety for the PTO circuit. The other switch (normally closed) with ORG & YEL wires is a safety for the Engine (Magneto) circuit. Thus, a person must be sitting in the seat for the engine to run and to operate the PTO.

AS A TEST........ Remove either the YEL or ORG wire from the seat switch and see if the engine stays running. Report back on your findings.

Sounds like you need a new PTO relay also, if you have to hold the switch up to keep the deck running.

On my 1863, the PTO will release (stop the blades), if the shift lever is put into reverse. Part of the safety not to mow in reverse. Suggest checking the reverse switch next to the shift lever.

The Reverse Switch mounting bracket broke off years ago. The switch is just hanging loose dangling behind the dashboard in the open position.

I replaced the relay to the Port side of battery. Not sure what it does, just that it is new. Obviously for lack of smarts, I tend to just start replacing stuff...

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.
