I was also thinking that replacing the gearbox altogether may be a simpler solution than finding a 4.6:1 gear reducer that can handle that power. You would need to find out what the gear ratio is on the hog and then try to match the mower speed with the new gearbox running off the mid PTO.For adapting your mower, here is a 40HP gearbox that is rated for 1000RPM input: 40 HP OMNI GEAR ROTARY CUTTER GEARBOX 250618

The one Aaron found is only rated to 1000 RPM. Here is one rated to 1800 RPM and has a 1:1 ratio. Gets you a bit closer.
