Hydraulic Skidding Winch Project

[BROKENSPROKET]

( I originally posted this in the Kubota Forum, but I thought it would fit here better)

Well, I am doing some research on a project to make a 3 point skidding winch. I checked out prices on a Weelenstien FX65 and decided to build my own and go Hydrualic.

I am pretty mechanically inclined, but I know relatively little about Hydrualics. I operate many things with hydraulics but I have never built anything with hydrualics.

I have a Kubota B8200HST-D which only has 19HP. It did not come with the Rear Hydraulic Outlet, so I decided to go with a PTO Hydraulic Pump and a Hydraulic Winch. I believe the Rear PTO puts our 16HP, but I don't know for sure

The PTO Hydualic Pump I am looking at will do 21GPM / 1000PSI @ 540RPM / 16HP. Now I have some research to do on hydrualic winches. Is 1000PSI enough to power a winch to get 6000 lbs line pull? IF not, I am guessing I will go with a Hydaulic PTO Pump with less GPM and more PSI to get more lline pull out of a Hydraulic Winch. I just have to figure out which PTO Pump and Winch to get and I am set.

IF anyone wants to offer any direction, I would appreciate it.

Very interesting - I have just started exploring "the hydraulic option", so I'll be watching for your progress. I'm interested in constructing a capstan winch with either hydraulic, chain or gear drive from the PTO. Do some searching and I think you'll find some very good information on skid winch configuration here on TBN.

For reference:
TractorData.com Kubota B8200 tractor information

Good luck & keep those questions, info (and pictures?) coming!

Do you have a model or style of winch in mind? If yes they should provide the specifications for that model. I.e. flow, and pressure Vs speed and torque.

Rough rule of thumb, you will lose around 20 - 30% of your input HP through the hydraulic pump and motor. This will depend on the style of pump and motor that are selected.

I think I will have to with a Hydraulic PTO Pump with 7.2 GPM to get up to 2250 PSI. IT's a Prince HC-PTO-7A.

I was looking at MileMaker H9000/H10500/H12000 or HI9000/HI10500/HI1200.
The MilkMarkers are rated for 3.5 GPM @1500 PSI. They are designed to run of power steering pumps. I have to find out if that would work or it I would blow it apart with 7 GPM @2250 PSI.

I found some other winches, but all the sepcs were listed in meteric and I have to took the time to do the conversions.

I have a homebuilt hydraulic winch that I made years ago for my pickup; had a log splitter pump under the hood (where AC compressor would go) and just slipped a belt on it when needed. I am currently adapting this to my tractor (I might need the winch this weekend).

I suggest that when you consider the cost and the amount of other components you will need (relief valve, reservoir, etc) why not add a rear remote or two to your tractor? This way you have a good source of hydraulic power for many other uses. Your tractor already has the pump, relief valve, reservoir, fluid...

A PTO winch will also need a gear box - probably worm drive - and that would be expensive also. My winch is very simple, a low speed high torque hyd motor with a #60 chain reduction to the spool. Bottom layer is 10,000lbs pull.

Those Milemarker winches are sweet; I would love to have one for my F250. If you are spending the money on one of them I would still think that adding auxillary hydraulics would be money better spent than a pto pump and solenoid valves.

BTW, flow does not make pressure. The pto pump you are looking at will be rated at 540rpm. You could use this but you would want to use slower engine rpm to reduce the flow rate (not reliable method) . A pressure relief would be required to limit pressure to the Milemarker's 1500 rating.

On the Mile Marker H & H1 series, 3.5 GPM @ 1500 PSI are the minimum input requirements. A dealer is going to get back to me what the top end allowable input is.

I checked with a Kubota dealer today and a Rear Hydraulic Oulet may cost $1,000. He is going to confirm a price with Kubota tommorrow.

A PTO Hydraulic Pump seems to be my best option. I won't need hydraulics on the back for anything else other than the skidding winch.

Well, this is certainly a learning experience. Total headslap momet. Off road recovery winches, line speed es muy lento.
So the FX65 ws looking better, but I only have 14.5 HP out the rear PTO, and 30 HP is required for 6500 lbs.

Unless you tie your tractor to tree will it pull 6500 lbs?

Using hydraulics you will not get any more power at the same pull speed than you will with PTO drive.

Do you have front hydraulics on your tractor? Will you be using these when you have the winch in operation?

Depending on where the quick disconnects are located on your B8200 could you just run some longer hoses back and use the existing tractor hydraulics?

Would potentially be a less money & work.

There must be something wrong with this; unless you are looking for (dangerously) fast line speeds I would guess you wouldn't need more than 5hp to run a winch. The milemarkers run off of PS; PS are not 30hp. Is the hp rating just to recommend an approximate size of the tractor?

I really think it's worth it for you to install a rear remote and either build or install an off-the-shelf hyd winch (milemarker).
