Flat belt pulley - gear ratio?

I'm considering building a pto driven capstan winch for my 9N. A flat belt pulley right angle gear seems like a good start to change the rotation axis, then replace the pulley with a capstan drum. I figure I'd need about a 10:1 speed reduction to get a reasonable rope speed. Is there such a thing as a pulley assembly with gear reduction?
 
A sherman step down or sherman combo in step down range would give you a lower pto speed. It is an interesting idea and I even have a capstan that I would sell cause I took off my winch
tractor to narrow the wheels to make it easier to maneuver in the woods.
Since the PTO flat belt pulley is only secured to the tractor using four 7/16" bolts if you did any serious winching it's likely that you will rip it apart.
I would suggest building a frame than add an electric winch, if you have 12 volts or a pto winch.

Too much. LOL. It's only 10K lbs. It was used to pull big boats out of the Delaware river near Philadelphia Pa. They also used them on trucks for rigging in the oil fields
 

If I had 12V and if I wasn't a cheap ba$tard I'd buy one of these and mount it to the back. 1500# is plenty for the work I need to do with it. I built a rake from rebar and a "launch" on my pontoon boat to take it out past the weeds in my lake. Last year I pulled the rake back in with the tractor, but the hill is steep and the ride back down in reverse is exhilarating to say the least. With a capstan style winch I can pull in 100 ft of rope at a pretty good clip and if I hook a monster I can just let the rope slip.
 
Belt pulley is step up over pto speed by 1.86 to one. Stated another way, belt pulley is 68% of engine speed.
 
[b:69196ea76b]This[/b:69196ea76b] will winch the boat and do the dredging.
Both problems solved! You might have to paint it to match. LOL

Would not be too hard to fab a carrier bracket attached to the rear
trumpet mounting studs that would hold an electric winch and 12V
battery. Could work out to be the cheapest way to go for intermittent
use. I would still pay attention to keeping it mounted as low as possible.
Hope you're staying warm and dry!

would sure like to have it though as I have several tanks that need cleaning of silt.

Thanks, that's what I expected - 1:1 or higher. You would want some belt speed for a cord wood saw or similar device. I was hoping there was another version out there with a step down for other low speed applications.

Haha, yeah, that would do it. It won't fit in my garage though.

The smaller cable winches I've looked at hold 50' of cable and have a retrieval rate of 7.5 ft/min. If I had as much spare time a you I could probably make that work, but I'm looking for a speed more like 60 ft/min.

I am staying warm and dry except when I get the sudden urge to drill a hole in the ice and drown some bait. You'd think I'd be smarter than that. How are things with you and Joan?

Thanks Kirk! That's a handy chart and has me rethinking my reduction ratio. I should have all the power I need at idle and I'm looking for a drum speed of about 60 rpm so 6:1 is probably a better ratio.

We're doing well, thank you. She's doing much better after this last surgery.

I wonder if you could make something work starting with the drive for the old cement mixers.
You'd still have to fab a bracket and change direction but gear ratio could be changed.

The cheapest way out might be to plant one or two anchor points up on the hill.
Then use the rope and a snatch block on the anchor point.
Then pull the weeds going down hill instead.
 
You could probably make something out of this ferguson pto gear reducer, if you can find one.

I've found a few 5:1 right angle boxes on fleabay rated at 2.5HP input with a C-face mount and 1" output shaft for less than a Franklin. Northern Tool sells a capstan drum with a 1" bore for $60. All that's left to do is make a mount plate adapter and a splined to straight shaft adapter. With the low input HP the gearbox would explode before there would be any damage to the pto shaft or housing in the event that I should hook Nessy. :shock:

I was thinking about a system like that with an anchor point, an anchored pulley and a snatch block in between. That way I could run parallel to shore and pull 100' of rope in 50' of travel. I've got a 2' diameter maple halfway up the hill that would make a great fixed point but haven't come up with a good way to anchor a pulley in the mud.
