I just fitted a winch to the front of my Nseries. I wish I had asked this question before.
The issue is the revs, I wouldn't want to over rev the winch as it would damage the hydraulics and possibly other things, so I thought I could run it at half revs since the HP requirement of the winch is 70minimum and the tractor is 130 I thought this would work. I hadn't factored in the fact that my tractor is an "e" model and so develops 1000 rpm on the front PTO at only around 1700rpm, so to get 540 you are barely past tick over. This means that my 5.5 ton uniforest can stall the tractor, and also that I can't use the crane at the same time as the winch as the min revs for the crane are 1300. I have been looking into various options to gear down the PTO and have more or less drawn a blank. They are out there but the vast majority can't take the HP. they aren't cheap either and the will also mess up the front PTO shaft geometry.
So I have decided that the best solution will be to lengthen the input shaft on the winch to take another cog and add a chain drive to another cog on another input shaft with a 2:1 reduction, this will then give me 2 input shafts, one for 540 and one for 1000. Uniforest do make a winch like this but it is setup for a clockwise PTO and mine is an anticlockwise one. So I have the advantage of being able to put anything off the back of the tractor straight onto the front, but it has made my winch setup a little annoying.
That said the winch on the front is awesome, we skidded out some heavy elm sticks with it the other day and the performance is great, as is the radio remote, well worth the extra.
If I were you I'd look closely at the torque and BHP graphs for your engine and see where the power will be when you are at 540 on the front PTO, not being an "e" model yours might make over 1200 rpm which would probably make a big difference. But then you want a bigger winch, which will suck more power......

It looks great, even in soft focus LOL..
