To choose the best used mini excavator, it is usually important to consider the type and age of the machine. These two factors will often determine what sort of maintenance has been required — and will be required — during the machine’s operating time. Everything from maintenance records to the machine's working conditions can separate the best excavator from all others. Examining the bucket, boom, tracks and cab is another important step, because these working parts are essential to operation. Price, budget and manufacturer also can help one determine which used mini excavator is the best.
Used mini excavators can vary so much that it is often important to determine the size and power needed before purchasing. Important related factors include the type and size of the engine, since some can work more effectively over long periods of time. Smaller models may run off electricity, while larger models often rely on diesel-fueled engines. The best used mini excavator will have sufficient digging force for the specific task. The types of excavators also determine their longevity.
When attempting to choose the best used mini excavator, it is often important to consider the age. Older machines might not last as long as newer ones, because machines often break down or become inefficient over time. For instance, an old excavator might have a weak hydraulic system or internal engine problems. Asking the seller about any known problems or past mechanical issues can help when one is trying to choose the best used mini excavator. Depending on how the excavator has been used, age can be one of the largest factors in used mini excavator quality.
The best used mini excavator likely will have been well maintained over its operating life. Generally, those machines with a reliable maintenance record are favorable to those with no record. Working conditions also can affect the type of maintenance required over time. Excavators used to move rocks, for instance, might wear out faster than those used to move lighter materials such as mulch.
The various moving parts of an excavator should be in good working condition. The bucket should be fully functional, with sharp teeth and full capacity. The boom and arm also should be working, with full pressure throughout the hydraulic system. Perhaps most importantly, the cab and all safety mechanisms should be completely functional. The best used mini excavator will have few problems with any of these systems though, if a minor problem is repairable, that excavator could still be the best choice.
