Can we break a Brush Mower by cutting full sized trees, heavy brush, stumps & whatever we find

What happens here

The engineer clarifies the hydraulic flow requirements for the brush mower, noting two different ranges. The lower range requires approximately 25-33 gallons per minute (GPM), while the higher range needs 34-36 GPM, and can go beyond 40 GPM. He stresses that while the mower might spin with lower GPM (e.g., 23 GPM), it won't deliver the full performance, leading to operator dissatisfaction. The weight of the unit, over 2,000 pounds, also necessitates a heavy-duty skid steer for proper operation and stability.

Goal: Inform about hydraulic requirements and compatible skid steer types.

Tools and materials

  • Skid Steer Loader Bobcat S185 — Illustrating machine compatibility
  • Trailer Erskine — Used to transport the skid steer and brush mower

to run this there's two different ranges I think the first one was about 25 to 33 or so and then 34:36 all the way up beyond 40 so there's two different motor sizes that we offered looking what does this one setup at this one is set up for the lower range so you want to rent this attachment you own a skid loader will the average skid loader run this attachment typically nope you know we're gonna see 25 gallons a minute if you had like say 23 it would definitely spin it and you could probably do some mowing with it but the kind of performance you're gonna be a little disappointed so your are your disc rpm wouldnt be there right but when you have it married perfectly together then what happens yeah well with this particular mower it feels like it can't stop it you just keep driving into the brush piles and piles of brush and it just keeps on going this piston motor really delivers on the performance you need a bigger tougher machine to do the job the right way and the weight of this unit I think is over 2,000 pounds too so that alone requires a fairly heavy machine material yeah you could just see that as the machine was pulling it off it didn't feel as tippy as the forestry mulcher but it's that definitely the heaviest brush hog that I've ever seen again a
