CHARLIE - a O/T 317 came with a series 1 KT17 from the factory. Think the later one's had series II's. The company made a factory kit to drop an Onan in them once they realized the problems with the KT17's. They would have had B43G's. The P218's & P220's weren't used till later in the O/T 318 & 420's.
I don't recommend hooking two tractors drawbar to drawbar, a pulling sled is a better way to compare pulling power. But with added weight to equal the 317 and proper tires for the surface your pulling on, a 147 could outpull a 317. Lug tires or chains for dirt, turf tires for hard surfaces like blacktop or concrete. Best advice I can give would be to let the 317 pull enough that the drive shaft from the engine to the hydro finally gives up and the 147 can pull it into the shop.
There was a frequent poster here years ago that put a driveshaft similar to what was in a 317 in a hydro Cub Cadet. I just laughed quietly at his efforts. The OEM driveshaft in a 147 isn't fancy but lasts a lot longer than the expensive drive shaft with two u-joints used on the 317.
The problem with the 317 when it comes to pulling is the frt weight bias. The lighter 147 you can add more weight to the rear. If you really want to tip the odds in your & the 147's favor, have your son-in-law add all kinds of weights to the frt of the tractor. ;-)
