    Default a homemade 3PH 2" receiver hitch

    I had my friend's digital camera last night, so I snapped a few pics before the sun went down. I already had a 3PH drawbar, so I added to it. I bolted the new hitch to it so I could use the drawbar as is later (if need be, probably not). I use this hitch mainly for moving trailers and boats around, but also use it with clevises and cables/chains to skid trees to the splitter. Sure is nice to slip a chain around a felled tree and lift the front off the ground before dragging it away.

    Looks pretty similiar to this product off the web.

    .

    I'm taking a welding course right now and this is my project. Any tips on things to do/not do??

    sorry to all who have a slow connection. I created an image tag to reference my web site because I could not post the pics as attachments for some reason. They're both 640 x 480, about 74KB in size.

    your right Knight, it does look like the "unamed" hitch you posted. I pretty much copied the design, BUT changed some things for my tractor. The upright on the "unamed" hitch is too long. I measured the vertical distance from the lower lift arm pivot to the upper lift arm pivot. I made the distance from the drawbar pins to the upper link pin this distance. I also measured the horizontal offset of the lower and upper lift arms on the tractor. The lower arm pivot is placed closer to the front of the tractor than the upper pivot by about 2". I build this offset into the hitch also. Now when I raise the 3PH from lowest position to highest position, the ball stays level. I guess these dimensions may change on different tractors, so measure yours. After making your plan, check to see if your upper link will extend out far enough to reach the theoretical distance. Mine did, but not by too much. Also, make sure your 2" hitch insert slides into the larger tube before welding. I bought a 2-3/8" O.D. square tube with 3/16" wall thickness. Take it from experience, a 2" tube will not slip inside this large tube because it has an internal seam. Also, I think the 2-3/8" dimension is held tight in manufacturing, but the 3/16 wall thickness is not (but you'll still have a seam on the inside). maybe someone knows the exact tube to purchase. I bought a new bolt-on step bumper receiver hitch from a discount surplus warehouse near me for $5 and ground off the welds on the mounting plate so I could use the tube. The rest of the steel was free, the drawbar was $18, and the two grade 8 bolts, nuts and washers were about $2 total.

    One last thing, if you read about the "unamed" hitch any, you'll see that they recommend a chain be fastened from the top of the upright to the swinging drawbar. On uneven ground, the 3PH will raise up (remember, no down force on 3PH, just gravity-down). Both on the "unamed" hitch and mine, there is a slot for a length of chain to slip in. 1/4" chain would work fine here. You would attach the other end to the swinging drawbar with an eye bolt. Your pic shows this. The excess chain would just go into the upright tube.

    Hi ya
    i think there maybe another reson why they have the chain ,what ya saying is right about the 3 point the other thing is so ya don't tow higher than ya drawbar ,also towing logs i'm hoping ya don't lift your 3 point right up as this will change ya pull point
    catch ya

    Thanks for the tips John. I just might have to knock a couple of inches off the vertical height. I'll measure the distance between my bottom link pivots and top link pivot tomorrow. Never really thought about that. I wasn't too sure how high to make it, so I took some rough measurements from my rear blade.

    I think I'll just get some sort of ring to go around the top link pin to chain the top of the hitch to the swinging drawbar. Should do the same thing.

    Did you put weep holes at the bottom of the vertical tube to allow water to get out? I've got a mental note to do that.

    Thanks again.

    jdkid,
    I'm very careful when lift logs to skid out of the woods. I have a FEL and put all my chains and stuff in the bucket when skidding. Did I say I'm very careful? I sure am!

    Knight,
    I had that thinking about the weep hole when I was designing it, but somehow it never made it in production. Every time I use the hitch, I say to myself "drill a hole...next time...". It'll get done. But, in my defense, my tractor and implements have a cozy spot in the shed, out of the weather.
    Also, on the spot to attach a chain- just grind or saw a 1/4" wide, 1" long (or so) slot centered on the back side of the upright tube. Put a clevis or eye bolt on the swinging drawbar and attach the chain to that, then slip the chain though the slot in the upright. The excess will fall into the upright tube and stay there- otu of the way. I had a short length of 1/4" chain, so I used that.

    I built my own 3PH 2" receiver hitch. It looks different but does the job.
