If you didn't get one, and didn't sign one, then go back to the dealer you bought the tractor at and tell them they didn't properly complete the pdi, and ask them to do it. At your place, where the tractor is. I have done it several times. Dealers get busy and they sometimes forget things, it's an unfortunate fact of dealer 'life'. With that, if I saw a assembly & prep ticket come across the desk, and no pdi sheet, if the tractor was sold, I'd go out after work and pdi it myself on customer's site. Farthest I ever had to go was 144 miles one way.
That pdi is a legal document, or more specifically it should be considered one. if you look at the bottom, it has a place you sign, and by signing you agreed that the dealer discussed certain things and you understand them.
I also know dealers that don't do pdi, period. No sheet filled out. I came from a motorcycle dealer. Motorcycles go fast and they have 2 wheels. Lot of them came in a crate with one wheel off and dealer had to install it. If ONE bolt was left loose, or improperly tightened, it could allow a wheel to come loose and when you have a bike that has over 200 horsepower and weighs 375 lbs, you don't want that to happen...if there was no pdi filled out for that bike, the dealer is automatically at fault for not doing the assembly & prep properly and if a case ever went to court, the manufacturer washes their hands of the dealer if there is no pdi. Now the dealer is almost always found at fault, without that little piece of paper.
It's real important no matter what kind of equipment the dealer is working with! And important that it is done properly (not just quick go through and put check marks on everything). Yeah us techs get in a hurry but there's never too much of a hurry when it comes to customer safety. Techs reading this take note of that. If your customer is standing over your shoulder, work slower and more methodically....make SURE you check things. Because if you don't, and he gets home to find ONE loader bolt slightly loose, they're gonna come unglued. Been there, done that.
