This is obviously the most commonly asked questions regarding a tractor purchase.
Different Makes and Models of Tractors
Some parts dealers don't like to sell parts for a gray market tractor. In fact, dealers of some brands of tractors are being told by a higher authority that they cannot willingly sell parts for gray market tractors.
Diesel Engines
Make sure you get a tractor with a diesel engine. Implements also work better on diesel engine tractors.
Horsepower
In a tractor the energy is produced from torque and engine speed. A 100 hp tractor is one with a maximum of 100 horsepower available at the power-takeoff (PTO) outlet.
PTO
Consider getting a three or four cylinder tractor. Three and four cylinder tractors are generally newer tractors and run quieter and smoother than the two cylinder models.
Transmissions
There are several different types of transmissions for tractors.
Manual transmissions on tractors were made to be shifted while the tractor is not in motion. Synchro Shift transmissions are basically collar shift transmissions (a type of manual transmission, see above).
Parts Manuals
Make sure there is one available for the tractor you choose.
