Well a lot of issues is also the whole mixed bag of new parts to make up a new machine, with many trenchers, tile plows and etc, the manufacturer gets an engine from source number one of one brand and finals from another, lasers and gps from a third and hydro pumps and motors from someone different yet, once it goes down under warranty, the machine and all the components are covered, but not necessarily by the manufacturer of the machine as a whole, the engine is covered by its own manufacturer, so when cat sells that engine to the plow manufacturer, the plow manufacturer has literally nothing to do with the warranty on the engine, you deal with cat directly, cat comes out with their service team to fix it, if parts are not available, your not taking any machine back to the plow manufacturer and just dumping it off and pinning a 20 dollar bill to their chest and saying, best of luck, your stuck and its your machine, the other issue is, the local cat dealership never sold that engine, got a commission, had anything to do with it what so ever, so you go to the bottom of the list as far as their concerned of importance, if they even care enough to put your name on the list in the first place, especially during the busy season when they are stretched thin anyhow. If your renting or leasing it, you can argue all you want about the payments, most or all your going to make anyhow, the one who wrote the contract has all that worked into it with all the legal loopholes already covered. If in doubt, tell whatever manufacturer your dealing with, you'll get your own personal lawyer to draw up a contract and have them sign it, see how long it takes to be shown the door and told to never come back. Business's have many legal staff on hand to figure this all out long before anything ever gets sold, leased, rented or whatever, the buyer is the one who has no experience with the legal aspects of it.........but get to find out later on down the road how it all works.
