After a solid month of planning and amassing parts, then leaving the project to collect dust for the last 9 months, I've decided to pick it up again and actually get my winch built. My tractor is a 4x4 John Deere 4600 hydro with 43 engine hp and somewhere around 34 PTO hp. This build is based off the winch in this video. I will not be initially incorporating any sort of drum holding mechanism like a ratcheting pawl or brake. Plans are to use 3/8" or 7/16" cable and the spool will be built to hold up to 300 feet if I decide to go that route.
The main frame structure is built from 2x6x3/16" tubing, 48" tall, 30" wide. I began by mocking the frame up, getting my height set up for the PTO.
Decided I liked where things were and got it tacked up. Mocked up the main cross member that will hold the 4140 shaft in place. The drum barrel is 3.5" pipe that has been bored to accept steel reducer bushings that hold bronze bushings that will be plug welded in place. I have some 1/2" thick, 13" diameter plates being made for the drum flanges. The 60 tooth 60 pitch sprocket pictured will have friction material attached. The plan is to use a length of 1.5" Acme rod and nut to apply pressure to the outer drum flange to press the inner drum flange against the driven sprocket to engage the drum. Again, just like the above video.
The shaft will be fixed in place with a pin block and I plan on center drilling it and drilling grease ports at each bushing point so I can grease the bushings from a single zero at the end of the shaft. I haven't put calipers on the flat plate crossmember yet but it's 5/8" if not 3/4" thick. She's going to be plenty heavy.
So at this point, I'll be mocking up the upper hoop that will hold the block and getting the 3pt attachment points in place so I have a way to move this beast around as it continues to get too heavy to move by hand.
