Welcome to NTT John. Man, I'm very sorry to hear of your stolen tractor.
That just ain't right. I hate thieves.
From the implements you have sounds like they were sized for your 30hp New Holland. I do believe you will need another 30 HP tractor or bigger to utilized those implements. You know what the new ones cost from buying your NH, but your limited funds to me means used. Depending on the work you have to do, and what tractors you find available ... you might get a tractor bigger or smaller than the NH and sell or trade the implements for ones to properly fit the tractor you are getting.
If at all possible I'd sell your truck so you are dealing with a cash transaction on the tractor. You'll have more options that way. The few folks you find who might trade could be motivated in the wrong way, and since your options are not as wide open when trading I'm afraid it's more possible to get a bad deal. All based on personal experience and this might not be the case for you.
Also check out

www.craigslist.com also might help you find the tractor you are looking for.
Good luck and keep up posted.
