There are a few downsides of a PTO winch. If the motor stops running it won't work. This is the only real benifit an electric winch has over a PTO or hydralic winch. I have only rolled a truck once and we set it up right with another truck. So I think self recovery to upright a truck really depends on several things. In most cases I wouldn't have anything to anchor off to do the self recovery anyways, lack of trees ect. A ground anchor would work but I a a long ways off from feeling the need to spend money on a ground anchor and or carry it with me. Burry the spare tire 3ft down and I have a ground anchor anyways.
Any ways, I am having a hard time buying a facorty PTO winch for my MQ. I could use an aftermarket PTO winch but it just doesn't apeal to me. If I am going to mount a PTO winch it is going to be a Nissan one. I find them all the time in New Zealand but buying it and getting it shipped here is a different story. The next thing on my mind when wanting to fit a PTO winch is the probs I may have by using a header, ie PTO shaft and header clearance. Then there is the issue with how far out a PTO winch sits on the front of the truck. I dislike this about PTO's and if mounting one would want it custom fitted back farther which means cutting up the grill and other mods.
So I am beginning to think the best of both worlds may be to run the PTO box but use it to power a hydralic pump which in turn powers the hydralic winch. I have the PTO box and just need shifter plus linkage to make this option work. While if I go full PTO winch I still need the winch, prop shafts and custom mounting. A small hydro pump would easily fit in front of the PTO box with some simple custom brackets. And it should be well up in the frame rail to protect it off-road. I could use headers this way with no worries. Hydro winches have always not appealed to me because you need to run the pump off the motor. That means a bit less hp and also more parts stuffed in the engine bay. Not to mention belt driven pump, belt goes while winching and you are screwed. I would think using the PTO to drive the pump is a much better option and would allow for a better pump to be used. The pump seems easy enough to find by using something from equipment or a tractor designed to be run off a PTO.
I don't know a lot about hydro winches but they seem to be very well designed. Fully water proof is something I like, I bet they run a lot cooler than an electric winch too. But how strong are they? How fast do they winch? How reliable is the hydro winch motor? Is opperation of one more like using a PTO unlike the hand held electric controller?
And the way I see it now $800 could be put torwards setting this box up for hydraulics.
