Size to the access, not the stump
Gate widths, surfaces and overhead constraints determine which machine can reach the work in your client base. A larger grinder excluded from half your sites earns less than a smaller one that fits.
Where this machine sits
The SC70TX is an upper-commercial arboriculture stump cutter — roughly 1,769 kg, a 67 horsepower diesel and a 584 mm cutter wheel carrying 30 teeth. It is specified for a tree business removing stumps regularly as part of its work, not for industrial plantation stump removal.
That distinction is worth making explicitly because stump removal spans two very different jobs. Grinding individual stumps in accessible settings is what this class does; clearing stump density across a conversion site is a shearing or tilling problem on a much larger carrier, and no arboriculture grinder scales into it.

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.

Where this machine earns its cost
Wrong machine when
- Large-scale land conversion — a stump shear or forestry tiller is the right technology
- High stump density, where per-stump setup time dominates

What drives the cost of owning this machine
In urban stump work, mobilisation and access dominate the economics rather than grinding rate. A machine that reaches the stump completes the job; a faster machine that cannot get through the gate does not.
Tooth cost per stump is the variable worth tracking. Urban stumps carry grit, buried rubble and occasional foreign material, and tooth consumption responds sharply to all three.
Where grinding follows a removal, completing it in the same visit avoids a second mobilisation. Where access forces a return trip, that trip is a real cost and should be priced rather than absorbed.
Ownership considerations in Australian conditions
Track tooth cost per stump
It is the clearest early signal of both grit conditions and operator technique. A step change is worth investigating rather than absorbing into the job rate.
Decide own versus subcontract on frequency
Own a grinder when stump work follows enough of your removals that subcontracting adds a scheduling dependency and a margin. The deciding number is how often it would work, not how often stumps exist.
