My log skidding/ballast hitch project
Thought I would share my latest attachment design.
I wanted a skidding hitch that also served as a trailer mover and ballast box. Nothing of this type was on the market so I developed one. My tractor, L3830 Kubota, does not have filled tires. So I determined how much ballast I needed by developing an axle loading equation in excel.
Here's a screen shot.

I determined wheel loading using a bathroom scale and long beam.
Worked great and is accurate enough for my purposes! 
To achieve 50/50 loading with loader empty, I need 550lbs of ballast at the 3 point.
I'll share pics of the hitch when time allows...

That's cool how you used excel to figure it out.

Yeah Excel makes the number crunching easy! Just gotta make sure I have my theory right.

Notice the use of choker chains and grab links. This is a great way to choke logs.

Re: My log skidding/ballast hitch project
The hitch is ballast is visible in a couple pictures. Laser cut steel 1/2" plate. It looks small but this hitch weighs in at around 550 lbs.

Also note is it compatible with my iMatch JD quick hitch.

Re: My log skidding/ballast hitch project
Great idea, Superb craftsmanship. Many of us can't justify a $4k farmi for the amount of logging that we do.
