1863 2 issues...
Hi Gang, I've tried to do some research, but I've yet to find an answer. I'm having 2 separate issues with my cub.
1. The starter only engages about every 10th turn of the key. Fully charged known good batter. Will spin the engine plenty fast. But more often than not, I turn the key and it clicks. Not a dead battery click. A mechanical click, like the starter is trying to engage, but isn't. When the happens, the PTO switch lights up very dim. If I turn the PTO on and hit the key, it lights up bright, and theres no click, you can tell power isn't getting to the starter with the switch on. 2. When I get it started it runs great. But when I engage the PTO, the blades start spinning but stop as soon as I release the switch. They will only continue to spin if I hold the switch in the full up position. The previous owner assumed it was a bad switch and rigged small bungee to hold the switch up. I have the manual, but I'm a bit confused as to were to begin troubleshooting these issues. It seems like the key switch can't be the issue as it is getting power to the starter solenoid. And it seems like the PTO switch isn't the issue as it does engage the PTO, and will illuminate at the dash when it's switch on, even if it's not held in the up position. And near as I can tell, this machine hasn't had the wiring modified in any way. Any ideas? Thanks!

Take off the ground battery cable where it connects to the tractor chassis.
Clean that REAL good, put some grease on the joint, and reassemble,, I have had that connection cause this issue on several tractors.

Some information on the starting issue here:
https://www.onlycubcadets.net/forum/...ad.php?t=38545 I had the same problem on my 1864 and installed a relay and no problem ever since. If you search you might find more info with pictures. Pretty common problem on your tractor I believe.

I had both of those problems with my 1863. IIRC the pto switch draws power from one place to start (switch all the way up) and another place to stay on (Switch in center).
I installed one of the relays to cure the engine starting problem. Some information and pictures here. https://www.onlycubcadets.net/forum/...ighlight=MM510

Yes, install the relay. I have a 1863 that had the same issue. Since the relay install, never had a problem. That link that was previously shared is great information and steps to install, cheap and easy.

OP your tractor has a reverse relay and a reverse switch that work with each other along with a portion of the seat switch that will limit the “on” or latch circuit of your PTO. Yes you have 1 PTO switch but it has a few functions internally which is why you can hold it in the start position but when released to run it no longer works.
The PTO gets disengaged when in reverse as a safety measure via the reverse switch and reverse relay. Not saying this is the problem but you need to check it. You can use a DVOM or cheap 12v test light to do so. We can walk you through it if you give us some readings.

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.
