I'm still looking for a used 673-873 or S220, 250 Bobcat. I want to run a stump grinder & brush hog. For a brush hog I'm thinking of getting one for a PTO three point hitch and getting a Bobcat PTO pump to mount on the Brush hog. Then weld a quick attach plate to the front of it. So I won't have to mess with the 3 point adaptors. I also want to get a hoe, dozer blade, & grapple. So do I need Hi-Flow? Or should I just look for a Machine that pumps 18-25 GPM @ 2500-3000 psi?

You'll notice much improved performance with the Brushhog if you go HF, but what did you mean by the Bobcat PTO pump?

Look here...... http://www.skidsteersolutions.com/pages/9/index.htm ............... I meant to take a pump like this and mount it directly on top of a brush hog made for a standard tractor. In stead of having this 3 point adaptor. I will weld a Bobcat mounting plate right on the front of the brush hog. I pretty sure I can pick up a used brush hog at an auction well under $1000. Pump will most likely cost 3-400$ Steel in the $150 range. So I think I can put one together for under $1500.00

Also BobcatS250 thanks for replying. I'm trying to figure out what I can get away with and if I really need the Hi-flow option. I plan on using this to help make a living. So if you guys swaer by the H-F I'll get one.

Sure thing. Also, 500k has some experience with the Bobcat Brushcat, so I'll defer to him for more opinions. I would think the HF will come in handy, but I do have my doubts about the safety of this type of set up. Best of luck to you!

RS Coyote,
High Flow need will depend highly upon your attachments. The stump grinder requires 17-32 GPM for operation as per Bobcat's specs (Bobcat recommends more than 20 GPM). An 800 series machine (S220 or larger now) will provide about 21 GPM flow max WITHOUT high flow. This would run the stump grinder, but may bog down under heavy loads. The PTO pumps that you are talking about won't need over 21 GPM (http://www.northerntool.com/webapp/wcs/stores/servlet/CatDsp?storeId=6970&N=96+1500). A PTO driven brush hog that you are talking about will most likely only be good for just that, brush about 3/4“-1-1/2“. A Bobcat Brushcat has much larger blades and faster blade speeds, so it can handle up to 3“ (I've done 4“ myself). The 60” Brushcat doesn't require high flow, but the 90” Brushcat will.
The Bobcat Brushcat may be a little more expensive route than the brush hog you are planning, but will be much more machine. The 60“ Brushcat is about $6,000 and the 90“ version about $9,000.
The high flow option may be harder to find in a used machine. High flow is usually targeted at specific attachments that the general user has no need for. Also high flow attachment are also usually high dollar. I don't know how much the stump grinder attachment costs, but I imagine somewhere between $8,000 and $10,000. Some third party flail mowers (for larger diameter small trees and brush) will run about $20,000. I heard Bobcat will be introducing their own flail mower this summer and should be about $12,000-$14,000.
I don't know how much money there is in stump grinding, but it may be hard to justify buying that expensive of an attachment and a high flow machine. If you are just starting in this business, I would recommend a standard flow machine in the 800 series range. This will give you a large enough machine to tackle the big jobs and about 4 GPM more hydraulic flow than the 700 series machines (S205 and below).
Maybe look at demoing a stump grinder from your local dealer. Try it on a high flow and standard flow machine to see the results. You may be able to buy a standard flow machine and just rent the stump grinder as needed. Make sure your machine has the Attachment Control Kit because the Stump Grinder will need it to operate. If the used machine you are looking at does not have it, you'll have to check how much it will cost to add it.

P.S. My Brushcat would perform better if I had more flow (currently my machine only has 16.7 GPM). It does OK now, but I just have to travel a little slower through thick brush or with larger trees. Like I said in my previous post, an 800 series machine will have 20.7 GPM which would be more than adequate for the 60“ model. Bobcat recommends a max flow of 28 GPM for the 60” model. The high flow in the larger machines is about 31 GPM, so more than the recommended flow. The 773 (S175/S185) machine will flow 26.4 GPM with the high flow option, but I heard these machines are a little underpowered for high flow operation. The S205 will flow 25.5 GPM and the extra 5 HP may offer good high flow performance. Just more food for thought.

I wanted to bring stuz's post from a while ago back up, and coyote, if you buy a NEW Bobcat loader (they now max at 40 GPM), you'll need to get a NEW Brushcat and not one of the old 60" or even 90" models. The flow will damage the components. Other than that, good luck. Stuz's post: http://www.bobcatforum.com/DesktopDefault.aspx?tabid=54&frmView=ShowPost&PostID=995

Good catch, BobcatS250, I forgot about StuZ's post. I checked Bobcat's website and it looks like the S220 and larger machines now have 40 GPM auxillary flow.

I stopped by Bobcat this AM and from this point on if you order a new S220 it will come with 40 GPM Hi-flow.

I don't think Bobcat has updated their equipment flyers or .pdf files on-line to reflect this change. The HTML specs on-line do show the increase in highflow.

Sadly, Bobcat isn't very good with updating their site whatsoever. Where's the 323 excavator? The T140? *sigh* The S220 now weighs 7500 pounds, but no reflection of that, either!

Bobcat's website is leaps and bounds ahead of Cat's and Case's websites for machine information. I was totally disappointed by Case's. On Cat's, it was quite a bit of searching before I could find some useful informatin. I'm sure Bobcat will have the latest info up shortly.

Agreed with Case, but then again, only so much we can do. Gotta live with the rest. Cat's I'm somewhat pleased with; it's been updated relatively well these past few years compared to in the past. Deere does a good job of posting News Releases but doesn't get their new machines up quite as fast. Anyhow: back on topic. :) Sorry bout that, coyote.
