Land-clearing businesses often need a different fleet philosophy entirely. Instead of owning six specialised purpose-built forestry machines, a contractor may operate a 20-30 tonne excavator with a forestry grapple, tree shear, grapple saw, stump shear and mulcher, supported by a dozer, a compact track loader, and a chipper or grinder.
The same base excavator can generate revenue from civil earthworks, demolition, vegetation clearing, log handling, tree removal, stump removal, road construction and drainage work. That substantially reduces asset concentration risk.
Land clearing is the segment where fleet philosophy diverges most sharply from plantation harvesting. The defining decision is not which forestry machine to buy but whether to buy forestry machines at all, or to buy a carrier and attach forestry capability to it. A 20-30 tonne excavator carrying a forestry grapple, tree shear, grapple saw, stump shear and mulcher does most of the same work, and does it while remaining saleable to civil, demolition and earthmoving buyers.
That redeployability is the commercial point. Revenue can come from civil earthworks, demolition, vegetation clearing, log handling, tree removal, stump removal, road construction and drainage, which means a downturn in one sector does not idle the asset. In a market where clearing volumes track development approvals, mining activity and seasonal fire work, spreading exposure across several demand cycles is worth more than peak productivity in any one of them.
The cost of that flexibility is that no single task is performed as efficiently as a purpose-built machine would perform it. A dedicated forestry mulcher out-produces an excavator mulcher; a feller buncher out-produces a shear on an excavator. The trade is deliberate, and it is the right trade whenever utilisation in any one task would be too low to justify a dedicated machine.
Rarely the order they get made in. Each step constrains the ones below it, so working upward from a machine you already like tends to produce an expensive answer.
The carrier sets the ceiling on everything that follows. Operating weight, hydraulic flow and pressure, boom geometry and lift chart determine which attachments can be run at all, and which can be run safely at reach. Buying an attachment first and then finding a carrier for it is how contractors end up with a machine that can close the shear but cannot lift what it has cut.
Mulchers in particular are unforgiving: an underpowered circuit produces a machine that cuts slowly, overheats and wears prematurely rather than one that simply works a bit less well. Confirm the required flow and pressure for each attachment against the carrier's auxiliary circuit specification, and confirm whether a dedicated cooling package is needed.
An attachment's rated cutting diameter describes what it can sever, not what the carrier can hold. Deduct attachment, rotator and coupler weight from the lift chart at the reach and angle the work actually requires, and check the result against the weight of green hardwood at that size. This is the single most consequential calculation in attachment-based clearing.
Attachments used weekly should be owned. Attachments used a handful of times a year — a large stump grinder, a specialist mulcher — often should not be. Hire converts a capital commitment into a job cost that can be passed through, and it keeps the coupler on the machine that earns every day.
Clearing produces material, and what happens to it determines the job's margin. Mulch left on site needs no handling; chip needs a chipper and a truck; windrowed material may need burning approvals. Quote the disposal path, not just the felling, because a clearing job priced without residue handling is usually priced below cost.
Every one of these has a larger effect on the hourly rate than the purchase price argument most buyers spend their time on.
Most businesses in this segment arrive at the middle stage. Knowing which stage you are buying into is what keeps the capital proportionate to the work.
Stage 1
A 20-30 tonne excavator with a forestry grapple, hiring specialist attachments as jobs require them.
Stage 2
The same carrier with grapple, shear or grapple saw, and a mulcher, supported by a compact track loader for finishing work.
Stage 3
Two or more carriers, a dozer, and a chipper or grinder where residue volumes justify it.
A shear rated to the stem diameter on site is the easy check. Whether the boom can hold that stem at reach is the check that prevents a rollover. Always run the lift chart with the attachment, rotator and coupler weight deducted.
The machine will appear to work. It will also overheat, cut slowly, and consume teeth and bearings at a rate that erases the margin. Confirm flow, pressure and cooling before purchase, not after the first hot day.
Specialist attachments used occasionally carry capital cost every day and earn on a handful of them. Hire is usually cheaper and always more flexible until the utilisation is genuinely there.
The felling is the visible work; the material is the cost. Jobs priced on hectares cleared, with disposal assumed, are the most common source of loss in this segment.
Put these to the dealer, the client, or yourself. An answer you cannot write down is an assumption.
