10 points to be taken into account when buying a used Trencher

If you are considering the purchase of a used Trencher, this article is right for you.

It is a real checklist to keep on hand when evaluating a used Trencher or when you ask for information about.


1 – Working hours

It is definitely a key indicator, even more year of manufacture. The number of hours gives the idea of the machine status. We could use this classification for communicative convenience:

  • 0 – 1000 hours: Machine in semi-new conditions
  • 1.000 – 2.500 hours: Machine in very good conditions
  • 2.500 – 5.000 hours: Machine in good conditions
  • 5.000 – more: Machine in precarious conditions

It is an absolutely general and generic classification; each used Trencher has its own history and its maintenance / repairs; however it is a fact that combined with following factors is fundamental.

2 – Year of manufacture

Trenchers are special machines that generally have not a daily use. They are highly reliable units with a great structure. The age of used Trencher is not a so restrictive fact: it is easy to find 20-year machines with 2000 hours and in excellent conditions, on the contrary might happen to find a few years machine with several problems. It is also true that a more recent used Trencher will be certainly more technologically advanced.

3 – Boom

It is the pivotal tool of the machine, on it converges all the power of Trencher. Check whether the wear strips at the end are deteriorated, if there are cracks or not. Also pays attention to its shape, is it a monolithic boom, thus a single iron piece, or it is assembled from more extensions? The first has on its side a greater resistance to shock, the second offers the possibility to set the machine for different depths depending on the work to be performed.

4 – Chain, plates and teeth

Chain, plates and teeth are the elements that have direct contact with the ground and therefore even those mainly subject to wear. Check the bolts holding the chain to the arm, thinner they are, shorter will be chain life. Also the condition of the rollers on which the chain slides can tell us a lot, if they are not completely cylindrical chain is not at the top. Same goes for digging plates. If the ends are deformed or rounded maintenance or replacement are necessary. Teeth must be changed whenever necessary; digging with little effective teeth is not productive at all.

5 – Controls

The cabin of a Trencher is a set of buttons, levers and controls. Try them one by one is an operation that protects from bad surprises.

6 – Maintenance during the years

Having a technical report of the maintenance done over the years is a surplus to be reckoned with. History of a used Trencher passes through inspections, revisions, breaks and relative repairs. If all this can be demonstrated is a good thing for sure.

7 – Tracks and self-leveling system

Tracks are an important component of the machine. They defy rocks, asphalt and mud and ensure the stability of the Trencher. Most of the used Trenchers today are equipped with a self-leveling system that allows maintaining the same excavation inclination also on non-linear ways. Check the correct operation of the system is something not to be missed.

8 – Belts

Almost all used Trenchers are equipped with a discharge conveyor that allows depositing the removed material to the edges of the trench during the excavation. The loading belt instead allows discharging on a truck that follows closely the Trencher. Presence or absence of this tool is an advantage to be taken into consideration.

9 – Engine

The heart of the machine. Start the engine and take a look at the engine block and the possible presence of smoke. Hear its noise, if you hear something odd or abnormal power losses. Check if the engine oil is in the correct quantity. Remove the air filter and inspect down the inlet to see if there is a dust trail. Ideal would also check if the engine develops predetermined power.

10 – Hydraulics

The hydraulic system of Trencher is as functional as delicate. A right thing would be to insert the gauges in the circuit to check that outputs are those reported by the technical specifications. Since almost all of today’s trenchers are hydrostatic, it would be wise to have an oil analysis report. This will reveal the condition of the hydrostatic pumps and motors. If there are metal particles in the oil, there may be serious problems in the near future.

Here the 10 most important points to verify and assess in choosing or evaluating a used Trencher.
Depending on the conditions of each of these points you can evaluate or compare your used Trencher.
It’s always recommended to go to check directly the Trencher to make sure of the information received.
