A 1030 is like a 930. if you have an IT service manual you can fix anything on the tractor.
I assume You DO NOT have 3 PT either?
It sounds like a coupling problem inside the tractor since you dont have PTO.
Pulling the back plate off the tractor is not that big of a deal.
It will require a good breaker bar set and a floor jack and an over head hoist or engine crane.
If you decide to tackle the job I'm sure people here will help you through it.
