Big D,
I just bought and received 2 - 16" disc hiller on 22" shanks ASC PART# 31752 , and 2 - clamp blocks ASC PART# 60878 , with 2 - wedge bolts ASC PART# 26614.
The Clamp block needed a few casting marks cleaned up with a Dremel Wheel, now they slide tightly over a 1.5" x 1.5" Solid Bar, which I plan to use as the " Tool Bar" , so I can adjust the width of the discs. I had to grind a little off of the Wedge bolts, so the Shaft shanks of the discs could slide into the mounting holes in the Clamp Block. The Clamp Block has 2 heavy set screws that LOCK the Disc Shaft for Height and Angle Adjustment.
My 73 year old Grandfather still plants a rather large garden each year, with 5 rows , each 70+ feet long of Potatoes, not to mention the 200 tomatoe plants , which he gives most of it away to neighbors and friends all over the countryside. I can't always be at the property when it is time to hill them. So I figure a couple dollars spent is well worth , knowing that all he has to do is hook up the hiller , jump on the tractor and be through hilling the potatoes in 5-10 minutes, rather than hoursssss like it has taken in the past.
My thoughts are to build the Tool Bar , then adjust the width and angle of the Disc , and the angle the disc engage the ground by adjusting the Toplink. With those 3 adjustments, you should have a wide range for different ground conditions. Loose, Compacted, Crusted tilled dirt, so on .....
I will post pics once I get back to the property, and get this project completed.
