I,m going to chime in with Midniteoyl and agree that, if what you say is true, you do have an action against the seller. His posts contain good stuff!
Let me add that some of your options are:
- Revoking your acceptance based on the undisclosed latent (hidden) defect. This would be asking the court to set aside the contract you give back the tractor and he gives you back your money. Understand that your revocation should be within a reasonable time from the time that you first became aware of the latent defect.
- Suing for breach of contract. Intentionally misrepresenting a fact relating to the tractor (which would include failing to disclose a known latent defect) is fraud and not only is fraud a tort, but is also grounds for breach of contract. Here again you could ask the court (if you win) to set aside the contract or, in the alternative, you could ask for damages in order to put you in the position you should have been absent the breach - you keeping the tractor but he would be paying to have it fixed. Keep in mind that if the contract is set aside then the "AS IS" portion of the contract is also set aside.
- Suing under a tort theory (fraud) which, in addition to actual damages, may allow you to ask for punitive damages (and maybe even actual attorney fees) which in theory are designed to teach people to stop doing bad things! And yes, this theory sometimes works!
- In addition, there is always the issue of collect-ability of any judgment that you might win. If he is judgment proof (no money) then of course you win but you lose! However, few people are really judgement proof. They work you can garnish some part of their wage. They have money in the bank you can take it. Certainly there is property that may be exempt from attachment, but much property is not exempt and thus would be subject to seizure. Even if they are not working and have nothing, you would add to their woes by negatively affecting their credit rating and on top of that, any judgement is (depending on your state) likely good for 10 or so years and may even be renewed for a second period. In effect, you would be his worst nightmare for the next couple of decades! He may settle up just to get rid of you!!!
All of the above are civil actions that you could pursue for yourself in small claims, or better yet, with the help of an attorney in regular court. You might consider talking to an attorney (they will often give you the first 30 minutes or so at no charge) to see what they think your chances are and in addition, they may take it on a contingency where there would be no fee unless you win and then they would take a percentage of what is collected. Before you think that such a small case may not be worth it for an attorney to do on a contingency basis, consider looking for a recent law grad that has just hung a shingle. They might have the time and the inclination to help you out.
Finally, many torts are also a crime! Many prosecutors are far too busy chasing killers, rapists, drug dealers, etc. to worry about little (in their minds) things like fraud but in smaller more rural areas they may take this kind of malfeasance seriously. You shouldn't threaten to prosecute someone as that is often a crime itself, but if it happens it really does put you in a great position because any plea agreement offered by the prosecutor is likely going to include resolution of a claim by the immediate victim of the crime which of course would be you.
These people get away with this crap because the victims are often uninformed, misinformed or intimidated by the prospect of a legal action - which makes them a victim a second time!
Anyway, the bottom line is that before you go on to do any work on your tractor I would suggest that you take a day or two and find a young hungry recently minted attorney and ask for that initial free consultation to see just where you stand in your particular jurisdiction.
Give it some thought and I (along with all the others here) wish you the best of luck!
