After a number of requests on the forum for the dimensions for the Troy Bilt Hiller/Furrower, I decided to photograph and detail the dimensions for the forum. This is only the bracket used to attach the hiller to the tiller. It does not include the "plow" part of the attachment.
To start, some general photos.
Here is a general sketch, albeit a little messy, showing the dimensions and the corresponding photo number below:
The thickness of and the width of the gap between the "tabs" that wrap on each side of the depth adjuster assembly of the tiller to attach the Hiller to the tiller. The tab plates are 3/16" thick. The gap is 7/16" wide, and the out to out of the tabs is 7/8". These plates are 4 7/16" long.
PHOTO 2 and 3:
The length of the plate between the "tabs" to the vertical bar in the back that the "plow" attaches to. It is 5 3/4" long from the end of the tabs plates to the face of the vertical bar.
PHOTOS 4, 5, and 6:
The width of the vertical bar that the "plow" attaches to is 1". The thickness is 3/8". The length is 6 1/4".
The height of the attachment plates is 2 1/2".
The height of the plate between the attachment plates and the rear bar is 2 1/4".
PHOTOS 9 and 10:
The hole that the pin goes through to attach the hiller to the tiller is 1/2" in diameter, centered vertically in the plates at 1 1/4", and is set in 1" to the center from the end of the plates horizontally.
The holes that attach the "plow" to the rear vertical bar are 5/16" in diameter. The lower one is 5/8" from the end of the bar to the center of the hole and the second one is 2 5/8" from the end of the bar to the center.
The angle between the horizontal plate and the rear vertical bar is 80 degrees.
The angle between the attachment plates and the horizontal plate is 175 degrees. Note: The photo is upside down to accommodate the angle gauge.
I hope these photos and dimensions help out in building one of these attachments. If you guys need more or better photos or more dimensions, feel free to post a reply. Of course, any and all questions are welcome.
