This is the machine that fits through a garden gate, sits on a trailer, and can be driven within ten minutes. Those three qualities make it the mini excavator most often sold to private owners — and the one where people get hurt because they feel safe.
Your manufacturer’s manual prevails. This page gives the order of the steps and the traps specific to this size; every figure — maximum gradient, capacities, break-in duration — must be read in your own manual.
1. Before delivery: can you legally tow it?
This is the question that sets this size apart from every other, and it must be asked before buying. Under a tonne, you haul it yourself — provided you are allowed to.
The figures below are the French rules, given as a worked example because this site is written from France. Every country sets its own thresholds — check yours. What travels is the method: the limit is not the weight of the machine, it is the rated weight of the trailer and of the combination.
In France the test looks at the trailer’s gross weight and the sum of the two gross weights (car + trailer):
| your case | what you need |
|---|---|
| trailer rated ≤ 750 kg | category B licence alone |
| trailer over 750 kg, but the two gross weights add up to ≤ 3,500 kg | category B licence alone |
| trailer over 750 kg and the sum falls between 3,500 and 4,250 kg | code 96 — seven hours of training |
A 900 kg excavator weighs more than its brochure says: add the bucket that is fitted, a second bucket, the fuel in the tank, and the trailer itself. The sum is worked out from the rated weights on the registration documents, not from what you think you are loading.
2. On delivery, before you sign
A delivery note signed without reservations closes off your recourse. Take the ten minutes.
- Walk around it before signing: dents in the bonnet, a scored ram, bent bucket teeth, chafed hoses.
- The data plate must be present and legible. Without the serial number, no parts order goes through and no clean resale happens.
- Count the attachments you were promised — buckets, quick hitch, keys, manuals. A missing bucket is claimed the same day.
- These machines often arrive strapped to a pallet. Check what the straps left behind: a bonnet crushed by a ratchet is easy to miss and expensive to fix.
- Photograph everything, with the truck in frame.
A useful reservation describes what you can see. “Subject to unpacking” protects nothing.
3. Unloading
The most dangerous moment of the day — and at this size, the most underestimated, because the machine “isn’t heavy”.
It weighs about as much as a small car, and its mass sits high and narrow. The steps every manufacturer prescribes:
- Firm, level ground, never across a slope.
- Ramps rated for the weight, clean — no grease, no mud, no ice — and properly secured to the bed, not just leaning on it.
- Never correct your line while on the ramps. If you are off, drive all the way back down, line up, and go again.
- Attachment tucked in and low: arm folded, bucket close to the ground.
- Slow down at the joint between ramp and bed. That is where the centre of gravity tips over all at once.
- Once loaded: chock the tracks and lash down.
Never jack the machine up on its boom to get on or off the bed. Manufacturers’ manuals forbid it outright.
4. Before the first start
- Check every fluid level yourself: engine, hydraulic, coolant. A machine can travel with the bare minimum.
- Machine on level ground, or you read the levels wrong.
- Find the battery isolator and the key position before you need them.
- Find the grease points: at this size there are few and they are easy to reach. Now is the moment, before everything is covered in soil.
5. First start
- In short bursts. A starter motor is not held down: crank for a few seconds, wait, crank again. Insisting flattens the battery and burns the starter out.
- In cold weather, use the pre-heat as intended — a few seconds only.
- ⛔ Never ether, never a starting aid spray. On a glow-plug engine the risk is explosion. Manuals say so in exactly those terms.
- Let it run about five minutes at idle before touching the joysticks. Cold hydraulic oil makes the machine soft and imprecise, and that is how you break a ram or clip a wall.
- Meanwhile: warning lights out, exhaust a normal colour, no odd noises, no leaks underneath.
6. Break-in
Manufacturers agree on the principle and the order of magnitude: for the first fifty hours, avoid full revs and full loads.
And above all: the first oil change comes well before the normal interval. New parts shed metal particles that the oil carries away.
Break-in is in the engine manual, not the machine’s. Many machine builders prescribe none themselves and refer you to the engine maker.
7. The real danger at this size
A one-tonne excavator rolls over. It rolls more readily than a three-tonne machine, because it is narrow and because you take it where a bigger one would never go: onto a terrace, along the edge of a fresh trench, across a garden bank.
- Reaching out to the side lifts a track. Arm extended sideways, on a slope, bucket full: that is the configuration that rolls it.
- A freshly dug trench is not solid ground. The edge collapses and the machine goes in.
- With the tracks retracted the machine is less stable. Retract them to get through, extend them to work.
8. If you work professionally
Rules below are French. A machine of this size falls under CACES R482 category A (compact plant up to 6 tonnes). The certificate does not authorise anyone to operate: what does is the authorisation to operate issued by the employer. Check your own national rules — the principle travels, the paperwork does not.
For a private owner at home none of this applies — but before opening a trench, run a utility search. A severed cable or pipe costs incomparably more.
Next
Once the machine is running, what makes it last is elsewhere: regular greasing, track tension, and service intervals kept.
