Clifford K has kindly provided a link to a gallery of photos that depict Charlie's early 446 Case that he has modified extensively. Charlie added his own flow control to the left side of the dash tower and a selector valve to the right side. The three point hitch is one that Charlie made for his tractor. The big red tall thing in the final photo is actually a hydraulic post hole digger Charlie designed and built for his tractor. That is the beauty of the Case hydraulic drive garden tractors. All sorts of hydraulic devices can be powered off the rear PTO valve.
Many thanks to Xfaxman for the three photos he supplied. The left one shows a factory J-26 three point hitch with the F-27 Sleeve Hitch Adapter connected to it. With those two items, the owner can hook up a wide array of attachments. The PTO valve is shown on the left side of the tractor next to the left fender and just behind the seat. The middle photo shows a PTO Kit by itself. There are the two long steel hydraulic lines, the mounting bracket with the valve attached and the hydraulic looping hose with quick couplers.
The right hand photo shows the PTO kit installed on a typical tractor by itself.
If you walked into a Case dealer back in the day, your Bill of Sale would show the price you paid for the basic tractor because that is how these tractors were sold. You then selected which size of mower deck you wanted and a separate price would be shown for that. If you wished to be able to rototill your garden, then you would need a sleeve hitch, a rear PTO kit to power the tiller and the Case H or J-70 hydraulic drive tiller. In addition, the dealer would have strongly recommended a D-10 wheel weight kit for the rear wheels, tire chains, a Flow Control Valve for better slow-speed control and a Front Weight kit to balance off the weight of the rear mounted tiller. If you want AG style bar tread tires instead of the Turf tires, then those could be had at the time of purchase.
The complete line of Brinly-Hardy aftermarket implements were available from the Case dealer. Therefore, single-furrow ploughs, single and double disc harrows, spring-tooth harrows, lawn rollers, aerators, seed planters, fertilizer spreaders, tool bars, thatchers and so forth could be had. Other suppliers to Case such as Hudson offered spraying equipment. There were also front mounted power brooms for sweeping, dump carts, snow blowers, utility blades for snow and dirt moving. There are many that I have not listed. There was no need for a mechanical PTO at the rear but there was a front-mounted 540 PTO that could power grain augers and hay elevators. Most of these attachments could be used on any of the Case garden tractors.
