To maintain the cutters as efficiently as possible, manufacturers may build such low-flow brush cutters with lighter disc carriers and only three blades. This isn't always the case, though.
Our experience has shown that, when used correctly and with the appropriate-sized skid steer, the performance difference between high and low flow brush cutters is minimal.
High Flow Benefits
In comparison to a low-flow brush cutter, a high-flow brush cutter may feature a hydraulic motor that is 100cc larger. The primary benefits of the high-flow motor can include:
To make a high or low flow brush cutter, some skid steer brush cutter models simply alter the size of the hydraulic engine. These models share the same architecture throughout all hydraulic flow ranges.
The Blue Diamond 60" Heavy Duty Brush Cutter 11-16 GPM is an example of a specific low-flow skid steer brush cutter. Three blades are supported by this type, and its parts are made to work as efficiently as possible with low-flow (standard flow) skid steers.
The Blue Diamond 72" Severe Duty Brush Cutter is an example of a brush cutter that employs the same design at both high and low flow rates.
Are Hoses and Hydraulic Couplers Different?

For high and low flow skid steers, the hydraulic couplers could have differing diameters; however, this varies significantly from machine to machine.
Higher flow skid steers might have 3/4" flat face couplers, but low flow skid steers typically have 1/2" flat face couplers. However, this isn't always the case, so be sure to check with the maker of your skid steer.
In order to handle the increased flow, high-flow brush cutters may have hydraulic hoses with a larger diameter.
Who Should Use a Low-Flow Brush Cutter?
A low-flow brush cutter is the best option if your skid steer can only operate at low flow.
You might, however, take into consideration a low-flow brush cutter model in specific situations for clients who have skid steers that can operate at both high and low flow.
Value of Investment
You can buy a lot of low-flow brush cutters for less money. It can make sense for clients to stick with a low-flow brush cutter if they want to save money on the initial cost of their first cutter.
