I intended to shoot the H and Y harness video today. There were too many mowers going, so I decided to test a few things.
Somewhere on the internet(I can't find it again) I read that MTDE's "H" harness, the Piri, is supposed to connect directly to the 1/2 round.
As far as I know, H harnesses are "supposed" to connect to the seat harness at the X of the leg loop and the belt. I hadn't thought of connecting directly to the 1/2 round.
Connected to harness
Connected to 1/2 round
As you can see, it's a 3-5 degree difference. That may not seem like much, but for anyone that is top-heavy and using the Frog System....it is a BIG difference. (Both photos are taken when I was completely relaxed.)
I did notice two issues to be aware of:
1 It clutters up your 1/2 round with two more things.
2 Depending on how the harness is adjusted, the lower straps might dig into your sides directly under your rib cage.
I also tried connecting the H Harness through the harness loops that the 1/2 round is attached to. Not a lot of difference...and it reduced the clutter on the 1/2 round.
Anyway....give all three a try above ground.
