With the continuous development of agricultural machinery, the enthusiasm of farmers' friends has been rising. However, the purchase of agricultural machinery requires a large sum of money. Therefore, many farmers' friends are more willing to purchase used farm machinery. Be sure to pay attention when buying used farm implements. The following takes the walking tractor as an example to introduce the points of attention for the purchase:
First, to find out the factory years
On the engine and in front of the tractor, there are factory signs with factory date. Then ask the car owner to buy a car date to determine the length of the car and the oldness of the locomotive.
Second, look at the new level of the main car and tires
Before buying, look at the oldness of the main vehicle and the tractor. If the tread pattern is smooth, there is no use value. At the same time, we must also pay attention to checking whether there are any scratches on the tire.
Third, look at the decline in engine horsepower
If you do not give pressure, if you crank the crankshaft, it means that the horsepower has dropped seriously. When cranking the crankshaft under reduced pressure, a crisp sound of oil supply can be heard, indicating a smaller drop in horsepower. After the engine starts, if there is heavy knocking at the rear, it indicates that the train of crankshaft or connecting rod is too large.
Fourth, see the technical status of the gearbox
Firstly, look at the locomotive from the outside for cracks and seepage. Then check whether the file is accurate and smooth, whether there is a gear shift, whether the transmission has noise, and whether the chassis is deformed.
