As you are looking at this article, then its obvious that you have an interest in vintage tractors.
Make sure that your tractor performs all the basic tasks properly, so check the steering, gears, forward and reverse, PTO, lift, lights, indicators and hydraulics. Even if you want to work on it straight off, you may not be interested in a full reconditioning for some time and need to minimize the number of initial jobs. You should have a detailed check list which included at a minimum the following: does it start easily from cold, run well when hot, all the electrical components work well, does it have good traction If possible you should go to your test armed with a toolbox containing a compression tester, expensive Fluke digital multimeter, hydrometer, and other specialty tools. or bring somebody with you who has these tools.. If you don't have these tools, don't panic as these tools can end up costing more than the tractor itself.. You should in this case rely on your own common sense and your own observation skills.
Does it start from cold? - A tractor that starts easily from cold will eliminate several particular problems at once Good Battery, compression, ignition wiring / magneto, tune up, fuel flow, Carburetor can be assured (not guaranteed) by this. If it doesn't start quickly from cold, it still may be a good machine but you will have to spend some time and money on it. One thing you should be watch out for is if the tractor is out and warmed up when you arrived, you lose an important checklist item, namely the cold start, because as we all know a warm engine starts much more easily then a cold one..
How does it run when warm - Make sure you get it hot, as you will want to ensure it doesn't overheat. When warmed up you should watch out for a number of problems. Plan on spending a half-hour running it. Look for leaks, both oil and antifreeze. Lastly after warm up, shut it down and see if it will start.
How well do the brakes work - Although relatively inexpensive to replace, they are difficult to get at on many tractors and will require a lot of work to replace.
Does the tractor smoke - Blue smoke indicates many potentially difficult problems like rings, pistons, or valve guides. White or black smoke can oftentimes be corrected with carburetion or ignition changes but still represent work.
Does the engine run smoothly - A simple ticking from the top of the engine may be a simple valve adjustment but a deep thunk from the bottom or middle of the engine would point to very serious and expensive repairs. The clunk should be more pronounced under load. This may be an indication of problems with the bearings, crankshaft or piston rods. And mean a very expensive repair job.
Work the hydraulics - Check the full range of the power rams by extending them with a load. Let the load sit in the hold situation for a period of time to be sure that there is no slippage. Chattering noises from the pump while lifting indicate the pump is not getting enough supply of hydraulic fluid. The pump might have experienced excessive wear when run this way for long periods of time and may be ready to fail.
While many of the above examples may sound a bit negative, you should do your background research and understand the specific issues a tractor may have before you invest.Patrick Malloney is an internet entrepreneur who founded Youtractor.com which offers 1,000 of tractor videos showing Farm Tractors
