Hydraulic Matching for Forestry Attachments
Flow, pressure and power are three different things. This guide explains how to read an attachment's hydraulic requirement, check it against your excavator and spot a mismatch before it costs production.
The rules that apply to every attachment on this site, from reading a lift chart to building a tender rate. Read these before comparing quotations.

These are the rules that do not change between attachment families. A lift chart works the same way whether the head is a shear or a grapple. A maximum rating overstates production in every category. Hydraulic flow has to be available under load no matter whose badge is on the machine. Rather than repeat that reasoning on ninety pages, it lives here once and the rest of the site links to it.
Read these before comparing quotations. Most of the expensive mistakes in this category are not made choosing between two brands. They are made by sizing an attachment from a brochure maximum, by pairing it with a carrier that cannot sustain the flow, or by comparing a delivered price against one that excludes the hoses, the bracket and the commissioning.
The about page explains where the specifications on this site come from and the limits of what they can tell you. Unfamiliar terminology is defined in the glossary.

A shear, grapple saw or root cutter holds the timber after the cut, so the lift chart at the real working radius, not the tonne class, decides what the carrier can control.
The maximum diameter on a data sheet marks a physical limit, not a production rate. Buy on the dominant stem size of your work, measured by sampling, and treat the maximum as the exception.
A clearing rate that survives contact with the site is built from separate cost lines, a measured sample block and an honest diameter distribution, not from a single hourly figure multiplied by a guess.
The purchase price of a forestry attachment is the smallest part of what it costs to own. This guide builds the full hourly cost, converts it to a cost per unit of work and shows why utilisation dominates.
Hire, dry hire and purchase each win at different utilisation levels, and the decision turns on paid hours per year, carrier compatibility and what the attachment will be worth when you sell it.
This guide explains what moves the price of a forestry attachment in Australia, what a headline figure usually excludes, and how to compare two quotes on the only basis that matters.
Australian hardwood raises cutting force, lengthens cycle time and shortens tool life, so European brochure figures and demonstration videos are a poor guide to what an attachment will produce on your site.
Continuous-duty attachments turn hydraulic power into heat faster than most excavators can reject it, so cooler capacity, cleanliness and oil temperature discipline decide summer production.
Mulching and grinding combine dry fines, dust and hot surfaces, which makes housekeeping, cleaning access and a planned suppression strategy commercial decisions rather than afterthoughts.
Mobilisation is a real cost line, not an overhead. This guide covers combined mass, floating the attachment fitted or separately, stands and tie-down, and why compact carriers win on distance.
A one-carrier, many-attachment fleet only pays if changeover is quick and reliable. This guide covers hitch type, circuit count, coupler mass, fleet standardisation and the real cost of lost time.
Clearing is a sequence, not a set of separate jobs. This guide shows how each decision constrains the next stage, and how one carrier with several attachments raises annual utilisation.
The purchase price is quoted once and the wear parts are bought forever, so get a written parts price list and lead times for every family before you sign.
A used attachment is only a bargain once its exact build is confirmed, its structure is sound and it has been run under load in real material rather than opened and closed in a yard.
A supplier who receives your carrier and site data can quote precisely; one who receives a tonne class can only guess. Here is what to send, what to demand in writing and how to compare.
Clearing native vegetation is regulated differently in every Australian jurisdiction. This guide explains the common triggers, who carries the obligation and how approval conditions change equipment choice.
Distance from the supplier changes the buying decision more than it changes the price, and this guide sets out what to establish in writing and what regional conditions genuinely change about equipment choice.
