This is my second Lawnmower Utility Trailer build, and is a step in the right direction. It all started when my wife was struggling to move chicken manure from the chicken coop to my father-in-law's garden late last summer. He said he really needed to get a trailer, and I volunteered to build one if he would buy the materials. I went to the computer and was surprised at how hard I struggled to find anything like I thought I could use when I looked over the Intructables website, so I set out to design and build my own.
If you are like me, welding is not an option. I wasn't worried about building the deck or the sides, but really had to concentrate on how to come up with some type of axle and some type of tongue-hitch combination.
I spent about a day getting mine built, but think it could be done in about five hours. Total investment for me was about $140, maybe a little less.

Step 1: Build the frame and tongue, and hitch
So here I have:
2 ea 2x4x6'-1/4" deck frame sides
4 ea 2x4x33" deck cross joists
I used a "little bit" to pre-drill starter holes for the 2-1/2" deck screws.
Next, I added the tongue-hitch-frame bottom combination board.
Here I have:
1 ea 2x4x8' tongue and center frame
4 ea rafter ties
16 ea (at least) 1-1/2" deck screws to attach the rafter ties.
I suggest you alternate the locations of the rafter ties. I also "toe nailed" a 2-1/2" deck screw at each cross joist as well.
This is the perfect time to go head and add the gate hinge strap to the tongue for your hitch. I used a wood chisel to chip out a little wood to get the thing good and flush with the 2x4. Bolt in with your 3 ea 5/16"x2-1/2" bolt-flatwasher-lockwasher combos, and tighten with 9/16" wrench or socket or pliers. See the pictures.
ONE THING ABOUT THE STRAP HINGE HITCH: I located mine at the bottom of the 2x4, and would recommend that you either move it to the middle, or even add a second one at the top.
