High Flow vs Standard Flow Brush Cutters


Are high flow brush cutters always better?

Our experience says NO.

When all things are equal on two brush cutters except the motor, there isn’t as big of a difference as many would think. In the industry, low flow versions of brush cutters are usually lighter built in many ways, reinforcing the idea that high flow cutters are needed for commercial or heavy use applications. At Blue Diamond, we lead the way in 2006 with one of the first low flow brush cutters built like a high flow, which actually out-performed most high flow brush cutters. Today, we continue this mission of keeping our low flow brush cutters comparable with the higher priced high flow machines. Recently we have been testing our low flow piston motor Severe Duty brush cutter at 23 GPM alongside our Severe Duty high flow model. This test has proven again that the difference is so slight that experienced operators (running these cutters every day) can hardly tell the difference!


Although we are more than glad to provide high flow brush cutters where they really are needed, there are times when the low flow version is advantageous.



How do I choose?

Obviously, if the machine only has low flow, the choice is clear.  Otherwise, there are a couple other things to consider.

  • Does the added cost of high flow justify the gain in performance?
  • Will the cutter be used on hilly terrain?

We have found that hilly terrain affects the flow to the brush cutter far more on high flow machines. In our experience, either the power to the tracks or the power to the brush cutter is affected while mowing up hills on most brands of skid steers while using high flow. The same machine in the same terrain using low flow is less affected and doesn’t bog out as much.


What performance gain does high flow give me?

We are often asked; how much will I gain by going to high flow? We feel that when comparing our same models (Extreme Duty low flow against Extreme Duty high flow) it’s about a 10% to 15% gain in performance.
