Interactive model comparison
Compare up to three models with shared-scale graphs for attachment mass and hydraulic flow, plus carrier bands and product links.
Do the arithmetic
Calculators and Tools
Every tool runs in your browser with nothing sent anywhere. The figures are only as good as the lift chart, data sheet and production trial you feed them.
Three of the four numbers that decide an attachment purchase are arithmetic, not opinion. What is left of the lift chart once the attachment package is subtracted. Whether the carrier can actually drive the head. What a machine costs per stem, stump or hectare once utilisation is honest. Each of these runs that calculation in your browser, on your figures, with nothing sent anywhere.
They are screening tools. A pairing that fails here will not work, which is genuinely useful to know before a quotation is prepared. A pairing that passes still needs the manufacturer's lift chart, the current data sheet and the supplier's written compatibility assessment, because none of these tools knows your boom configuration, your ground conditions or the mass of the timber you are holding.
The glossary defines the inputs if any of the terms are unfamiliar, and the FAQ answers the questions these calculations tend to raise.
Clearing method comparison
Compare two methods at the same finished outcome. Calculate cost, hours and break-even quantity using your own rates.
Attachment matcher
Enter your excavator tonnage and auxiliary flow to list every model whose published carrier and flow bands overlap, across all eight categories.
Lift capacity calculator
Subtract attachment, rotator, bracket and hitch mass from your lift-chart figure at the working radius and estimate the timber section you can safely control.
Hydraulic power calculator
Flow multiplied by pressure divided by 600: a fast sanity check that your carrier can actually drive a mulcher, grinder or saw motor.
Cost per unit calculator
Build an hourly ownership and operating cost, divide by production, and get a true machine cost per stem, stump, hectare or hole.
