This is a DIY version I made with my grandfather several years ago. Originally had it on my Wheelhorse for snowblowing, which I still use to mow but the snowblower sits in storage.
The frame is 1/2" EMT conduit, and the black and clear fabrics were sewn by a local Amish guy my grandfather knew. I can't remember what it costs us but it was a lot cheaper than even the Bercomac (around $800).
I did have to make different brackets to mount to the Kioti, and had to cut a few inches off the rear legs so it sit more level. Just today I added some magnetic fridge clips to hold the lower fabric tight to the metal floorboard and fenders.
No heater, but I get a bit of residual heat from the engine and just keeping the wind and falling snow off me makes a huge difference from being totally exposed to the elements.
