anyway has anyone ever mounted a hydraulic pump to the engine? Do they make one?
The work-truck builders use a PTO-powered hydraulic pump so they can get lots of reliable hydraulic power. They then use the hydraulic power for all sorts of things, including air compressors, generators, lift cylinders, winches, snowplows, etc.
All SuperDuty trucks with stick shift include the "PTO Provision" in the transmission. Automatics will have it only if the optional PTO provision was ordered with the truck, so very few automatics will have it.
If you have the PTO provision, then you can add a PTO. You'll need two things:
1. PTO. The PTO provision is basically just a hole in the side of the tranny where you can install a PTO. Ford doesn't sell the actual PTO. Two primary sources for the aftermarket PTO = Parker's Chelsea division and Muncie.
Chelsea is now owned by Parker.

The right Muncie for your truck with automagic tranny is
Muncie Power Products Power Take Offs: FR/FA Series
2. Notice Muncie sells not only the PTO, but also the second thing you need = the hydraulic system that is powered by the PTO, including PTO-powered pump, tanks for hydraulic fluid, and distribution lines for the hydraulic power.
But get out your checkbook. The PTO and hydraulic system installed by a truck upfitter will cost you about $3,000 or more. When building a $60,000 work truck, $3,000 is only 5 percent of the total price. But as a mod to an old truck just to make the snowplow work good, it's a bundle.
Plus if you have an automagic tranny without the PTO provision, your first step is to replace the tranny with one that has the PTO provision. You can buy a Ford rebuilt 4R100 tranny with the PTO provision for around $2,500 from a discount Ford parts dealer, such as Tousley Ford.
