Log Max 7000XT

Name: Log Max 7000XT
Brand: Log Max

The heavier Log Max head for ~25-30 t carriers — more capacity and feed force, at 555 kg more mass.

7 published specifications

Positioning

Where this machine sits

The 7000XT is the heavier member of the same family, moving the carrier requirement to roughly 25-30 tonnes and the flow requirement to 250-350 litres per minute. The published figures tell a consistent story: 800 mm maximum cut and 45 kN feed force, bought with 555 kg more mass than the 6000V.

That mass is the decision. More capacity and feed force are useful only on material that demands them, and the additional weight has to be supported at reach by a larger and more expensive carrier. The comparison between these two heads is a good illustration of why head selection should start from the stand rather than from the specification sheet.

Interpretation

What the published figures actually constrain

A specification table tells you what the machine is. This is what each of those numbers means for the work you would put it to.

Published figure	What it means commercially
~1,897 kg weight, ~25-30 t excavator class	The extra mass over the 6000V moves the carrier requirement up a class, which raises the capital of the whole combination rather than just the head.
45 kN maximum feed force	Substantially more pulling capability, which is what wins on crooked, branchy or heavy stems. On clean uniform material the advantage over the lighter head narrows considerably.
250-350 L/min flow	A more demanding hydraulic requirement that the carrier must sustain continuously. Confirm continuous flow and working pressure, not peak figures.
~800 mm maximum cut, eucalyptus roller options	Capacity for large stems, with species configuration available. As always, configuration determines whether hardwood output meets specification; capacity only determines what can be cut.

Before it fits

The four checks that decide whether your carrier can run this

Each of these can fail independently, and passing one says nothing about the others. Weight class alone is the weakest of the four and the one most often relied on.

Check	For this attachment
Mass the carrier must control at reach	~1,897 kg plus rotator and coupler — 555 kg more than the 6000V, which is what moves the requirement to a ~25-30 t carrier.
Continuous hydraulic flow	250-350 L/min sustained. A carrier at the bottom of its class may meet the weight requirement and not this one.
Working pressure	Verify pressure held at continuous flow; 45 kN of feed force depends on both together.
Cooling under sustained load	Higher throughput means more heat. Confirm the cooling package suits continuous duty at your ambient temperatures.

Commercial fit

Where this machine earns its cost

Right machine when

Larger stems where the 6000V would be working at the top of its range continuously
Heavy eucalyptus processing where feed force is the constraint
A carrier genuinely in the 25-30 t class with hydraulics to match

Wrong machine when

The dominant stem class is comfortably inside the 6000V's range — the extra mass reduces effective boom payload and agility for no gain
Transport mass is already marginal

Running cost

What drives the cost of owning this machine

The heavier head has to earn its additional capital and its larger carrier requirement through throughput on material the lighter head handles poorly. Where stems are well formed and inside the 6000V's capability, the 7000XT adds cost without adding production.

Carrier class is part of the head's true cost. Moving from a 21-25 tonne to a 25-30 tonne carrier changes capital, transport and operating cost across the whole combination, and that comparison belongs alongside the head price.

Feed force is most valuable where it prevents lost cycles. Time spent re-gripping a stem does not appear as a fault, only as lower throughput, which is why it is best assessed by witnessing the head on your material.

In practice

Ownership considerations in Australian conditions

Compare against the lighter head on your stem distribution

The difference between these heads is which material they handle well, not which is better. Run your volume distribution and stem form against both before assuming the heavier head is safer.

Confirm the carrier can sustain 250-350 L/min

Continuous flow, working pressure at that flow and cooling for sustained duty are separate from the machine's weight class. A carrier in the right class can still be short on any of them.

Check the lift chart with the head fitted

An extra 555 kg at working reach changes what the carrier can do on slopes and at distance. Run the chart at the geometry your work uses, not at the machine's best case.

Questions

Common questions about this machine

Is the 7000XT worth the extra 555 kg over the 6000V?

On crooked, branchy or heavy material where feed force limits throughput, yes — the extra pulling capability prevents lost cycles that never show up as a fault. On clean, well-formed stems inside the lighter head's capability, the additional mass buys a larger carrier requirement and more capital for production you will not see. Assess it against your stem form, not against the specification gap.

Does the heavier head need a different carrier?

Yes, and that is a material part of its cost. The published class moves from roughly 21-25 tonnes to 25-30 tonnes, and the flow requirement rises with it. Compare the full combination — head plus the carrier each requires — rather than the two heads in isolation, because the carrier difference is frequently larger than the head difference.

Can I run this head on a carrier at the bottom of its class?

Only if the carrier meets every requirement, not just the weight class: continuous flow of 250-350 litres per minute, working pressure at that flow, cooling for sustained duty, and a lift chart that supports roughly 1,897 kg at the reach and angles your work actually uses. Weight class alone is the weakest of those four checks and the one most often relied on.
