PTO

Old school and new school . . .

PTO and Dyneema.jpg

Here's something you don't see every day: a PTO winch spooled with synthetic line.

PTO (Power Take Off) winches were common decades ago on Land Rovers and Land Cruisers. Rather than being powered by electricity, they ran off a driveshaft attached to an auxiliary gearbox on the transfer case. The advantage to them was that as long as the engine was running, the winch would run as well, with zero danger of overheating as is quite possible with the electric version. The disadvantage, of course, was that if the engine was not running, neither was the winch. These days very few vehicles are equipped with the take-off point on the transfer case that accepts the PTO driveshaft.

I had a PTO winch on my FJ40 for some time, but after I swapped transmissions I kept putting off cutting the hole in the new tunnel for the operating linkage, so the winch became nothing but a fashion item. When a Warn 8274 electric winch presented itself as the perk from a review, I swapped that in and sold the PTO for four times what I'd paid for it.

Probably a mistake—one Maggie McDermut did not make with her BJ74 Land Cruiser. At the 2018 Overland Expo West, the lads from 7P Overland spooled 80 feet of 3/8ths-inch Dyneema onto the drum, and spliced in a Factor 55 thimble. She now has the best of old and new. 

The drive mechanisms on PTO winches varied from year to year and maker to maker. Maggie's is perhaps ideal, in that the winch can be run in any gear, depending on the speed and power needed. Choose first gear for low speed and high power, or run it in second or even third with more throttle if you're just pulling a small log off the road. The single disadvantage of her setup as it is now is the hawse fairlead, which is inset into the chrome front bumper, and could very well let the line contact the edges of the opening on either a right or left-side off-center pull. She'll need to use caution to arrange a straight pull.

I hope she gets a chance to use it on her journey to Alaska as a Change Your World Fund grantee.
