Well engineered and built! Have had my homemade brush cutter for 10 years ow and its still the best choice for smaller hard to reach areas or those with obstacles

[@AlwaysBored123]

Thanks but you might not say that if you saw it up close lol. These king kutters are not all that heavy duty and I don't think my hackery helped things much. Does work good though. You just have to be gentile with it to keep from bending anything up.

[@oby-1607]

Thanks for the food for thought. I have a John Deere brush cutter that will cut easily 3 inch trees but is on the back of my tractor. Mounting it to the front would make my life (my neck) feel a whole lot better. Your idea looks like it works good.

[@orchardtvchannel]

That is great use of a old mower. I like

[@houndsmanone4563]

Great build. I admire the methodical approach. Enjoyed a full-watch of your video. Subscribed!! 👍🏽🙂

[@AlwaysBored123]

Thanks a lot!

[@captaina7433]

thanks for sharing. I did laugh when I see you grinding so close to your car. lol

[@AlwaysBored123]

Haha yeah. All that grinding was a messy, loud, PITA. If I do something like this again I will be sure to get a plasma cutter first.

[@begoodamerica9793]

Awesome, Nice to have a yard were you can store supplies or as wife says "junk" Thanks for the video

Killed it!

[@michaelagnew7825]

better than the best already

[@iainhetherington4608]

Well done lad what type of hydraulic motor did you use ? Cheers from Aus

[@AlwaysBored123]

I used a Parker-Hannifin model TG0140MS030AAAA which is a gerotor motor with 140 cubic centimeter/rev displacement . I chose it because it was readily available, did not require a case drain, and Parker's technical literature is easily accessible. Thanks for watching!

[@hillbillyfranks]

What size hydraulic motor did you put on that Brush hog You did a good job on that Enjoy it be watching again

[@AlwaysBored123]

Parker TG0140MS030AAAA. 140cc/rev I think.

[@hillbillyfranks]

Thank you very much have a good day

[@MrLouie1900]

im going to do a front mount brush hog also thanks for some ideas on this. food for though! you should have moved the car out of your garage.

[@wildmanofborneo]

Hi if this motor was driving a 3 point hitch PTO chipper, and the chipper has a heavy flywheel that has a lot of momentum, when the hydraulic flow is turned off, the flywheel would keep turning and the hydraulic motor would become a hydraulic pump. Would it pressurize the input lines with the same "polarity", or would the "polarity" flip? Polarity meaning which line has higher pressure (supply line) and which line has lower pressure (return line).

[@AlwaysBored123]

It would flip. The fluid continues to flow the same direction through the circuit, but the return line would become the higher-pressure side and vice-versa due to the motor now acting as a pump. Like how if you pedal an exercise bike quickly it tries to pedal you when you stop.

[@CPLBSS88]

easy enough to put a one-way valve and over pressure dump valve with return line to tank...

[@wildmanofborneo]

@CPLBSS88 I think you only end up needing to have a crossover line with a check valve. The circuit will end up pumping in a circle and slowly dissipate the energy. No need for a dump valve.

[@godspeedparadeteam]

Fantastic video looking for brush cutter to hack up!

[@simjohndeere]

whats the number of your case skid steer?

[@AlwaysBored123]

It's a model 430 series I

[@cccorvette]

Great video. I'm about to tackle one myself.

[@captaina7433]

Why didn't you place the hydraulic motor vertical, and bypass the gearbox entirely?

[@AlwaysBored123]

The short answer is because it was simpler. The input shaft on the gearbox is a standard size which makes it easy to connect to the output shaft on a variety of motors. The output shaft on the gearbox that the blade holder mounts to is both splined and tapered, and I don't know of any common hydraulic motors that have the same shaft. Additionally, you would need to ensure the motor was rated to handle the radial and axial loads it would see if you mounted the blades to it directly. In that regard the gearbox is nice because it acts as a sort of mechanical fuse. Should you suffer a catastrophic failure you're only out a cheap gearbox instead of an expensive hydraulic motor.

[@bradpritchard3864]

I have an older 5' heavy duty brush hog I'm thinking about converting. I don't believe it has slip disk in the housing. What happens when you hit something unforgiving? Is that what you drilled the hole for, for a shear pin?

[@brwpe7733]

What are your gallons per minute on the machine? What horsepower is your machine?

[@AlwaysBored123]

Engine is rated at 80hp. Hydraulic output is 21 gallons per minute at 3000PSI which works out to about 30-35 hosepower. It works out slightly better than a 30 horse tractor because, instead of having to split 30hp between the cutter and the wheels, you always get a full 30 to the cutter and are able to drive the wheels with what's left over.

[@brwpe7733]

Thanks for the info. I'm doing the same bush hog (6' king kutter) but I'm putting it on a John Deere 7775, it's the same as a new holland ls160. 50 hp, 17 gpm 2600ish psi. It should do what I need. Yours did great imo.

[@Tomsfoolery.]

@@brwpe7733 did you ever get it working on your john deere? I also have a 7775 and want to do the same thing.

[@brwpe7733]

Santer Auto Repair LLC I did get it to work and it does a pretty good job. Of course it’s limited compared to newer higher output machines but it beats weed eating. If there’s a way to communicate, send me your email or phone number I’ll be glad to tell you what I did and what I’d do different now that I have some experience with it. Overall I’m very happy.

[@dEE_Oh_g]

@@brwpe7733 can I get the info you’re talking about. Shoot me a message with your email. I’d love to hear your input

[@MrRds1964]

Pretty nice clothes for fabbing. Lots of weld rash too.

[@AlwaysBored123]

I don't know that I would describe those clothes as "nice" per say but yeah who needs a tanning bed when you have a millermatic lol.

[@gilbertaguirre5375]

hey you sure put a lot hard work on it.. that's pretty smart.

[@jd8230]

You need a plasma cutter. Why not just make the skid loader mount where you took the caster wheel off

[@AlwaysBored123]

I agree. A plasma cutter would have made this 100x easier. You could attach the mount to the wheel end but that would have required more fabrication. Since the original mounting point was the other end it just made sense to reuse it. And I wanted both ends open anyway so it worked out good to flip it around like that and run it "backwards."

[@jimmybrown9595]

You can buy brush cutters ready to go 14 to 26 gpm low flow well built that cuts up to 7 inch materials for $2800 I don`t see it being worth the time to build one.

[@AlwaysBored123]

I looked into that. Those cheap cutters kinda suck. They're fixed mount so unless the ground is perfectly flat the cut is terrible. Also they always use undersized motors (often no-name chinese ones at that). And no rotary cutter is going to tolerate many 7 inch trees. You need a mulcher for material that big. This cutter isn't amazing but it's certainly better than an ebay special. And for me it was way cheaper.

[@jimmybrown9595]

Ok I have a cutter bought new 3 years ago used for around 600 total hours and only replaced blades once so far. Eaton motor works great.

[@TheMitchclark]

We're is this $282 hydro moto? Great build btw . best i can find is $1200 Parker .

[@AlwaysBored123]

I believe I got that from some kind of surplus/overstock store on ebay. They pop up there every so often you just gotta keep your eyes peeled. New prices are insane as you've seen.

[@TheMitchclark]

Apprciate it i have an old brush hog like yours and need one for my skid... Thanks for the inspiration. Keep it up 👌

[@Yangar03]

Great job ! At 14:12 you connected a by pass hose, what is the reason for that, is there a one way valve there?

[@AlwaysBored123]

Yes. When the flow is shut off from the machine the heavy blades spin the motor with considerable force and cause it to pump fluid. That hose and check valve (one way valve) allows the fluid to flow directly from the outlet of the motor back to the inlet. This lets the motor coast down freely instead of dead heading and jamming to a stop.

Well the only other options I could think of were silence or the wonderful sounds of angle grinders and sledge hammers.
