bradco ground shark

Absolutely. :liar:

ShadowCat, 32 GPM is enough. But it's like my old man always says, "To much power is just right, and there is no replacement for displacement".

Yeah, was also looking up about PSI... the 289D goes up to 4,061 PSI in High Flow, so that gives me hydraulic horsepower rating of 75.8, which is higher than many higher gpm 3,000 psi units. So much to factor in with all of this!

Nice Video Lumber

I had an "issue," or perhaps "conflict" is the better word, with the safety chain that fouled the blades pretty well. I took care of that issue.

The knives are nearly as sharp as chipper knives, roughly. The mowing in the video didn't appreciably wear the blades.

Any more detail on the safety chain blade "conflict" that resulted in premature blade dulling that others may learn from to avoid in the future, that you are willing to share.
Being totally self centered about this, as I am looking at the Bradco and want to avoid the same "issue" if I do get it.

As and end user I can say I have absolutely no need or desire for the height limiting chain on the back of the mower.

My course of action was to take the torch and remove it. I can report the operation was a complete success, it hasn't fouled the blades any more!

Thanks for the clarification

Don't forget when calculating Hydraulic Horsepower to multiply your product (flow x pressure / 1714) times .85 for parasitic loss in the hydraulic system. this gives the Cat 289D 64.4 hyd hp.

I've sold these Groundsharks and I am a big fan. I've not had any customers come back with any issues.

Then factor in that most machines don't make published pressure at published max gpm by a wide margin.

Yep lumberjack, the published numbers for my machine required 230hp just to drive the cutter pump, hard to get that out of a 140hp engine.:confused2:
