Rear lifting bar dimensions

Postby Bob McCarty » Fri Jun 21, 2019 2:17 pm

This is the bar that is bolted onto the rear rockshaft and the cultivator spring rods attach to. If someone could measure parts and dimensions, I'd appreciate it. Need to make one.

Thanks, Bob

Good morning Bob !

Here yah go:

The bar stock is 1" diameter; ends are not turned but, sheared at the factory. Overall length is nominal 20 1/8"

The details of the end drillings for the cotter pins are: 1/4" d. holes (to allow 3/16" pins); first hole 1/2" on center from end of bar stock; second hole is 2" on center also from end of bar stock, net 1 1/2" apart on center. All cotter pin drilling done in the same vertical plane.

The truncated, right triangle plate for attachment to the lifting arm: 3/8" thick X 3 1/2" base X 4" height; truncated to 1 1/4" at the top of the height and, 1 1/2" where the hypotenuse meets the base. Drilled on the height at 1/2" d., 9/16" inward from the vertical edge, lower hole center line 7/8" above the base, upper hole 3 3/8" above the base, net 2 1/2" apart on center.

The bar stock mounting into the plate: 1 1/16" hole, drilled 1" on center above the base, 1" on center in towards the height from the truncated end by base/hypotenuse.

The locating of the lifting bar into the plate for welding has particular alignments: the height of the plate is parallel to the cotter pin hole drilling, therefore, the base of the plate is at right angle to the cotter pin drilling. The bar stock is positioned in the plate with the two(2) mounting holes to the lifting arm up, resulting in the hypotenuse being vertical and, 9 3/8" of the bar stock exposed to the right of the plate; it is fully welded to that side of the plate, square in both planes to the one another.

This allows a nominal 10 3/8" of bar stock exposed to the left of the plate.

I believe the lifting bar is mounted to the right side of the rear lifting arm and, the offset of the plate then allows the net result to be a nominally center attachment. All left-right-up-down-front-rear references are as the operator is onboard driving.

So, Bob... there's a 'thousand words' about it ! Threw in some pictures as I like pictures too :{_}:

WOW! I'm an engineer (by training only) and that is one of the best verbal descriptions of a 3-D item I have read! Good job.

Now, get going, Bob!

Thanks :hattip:

You outta see my discription of a Spiral Staircase to someone who has never seen one :lol:

Guessing you can tell I've got some formal background in engineering and machining however, being "Old School", it took me longer to draft the post and get the pictures right, then it would have to make a rear lifting bar :shock:

Anyhow, here's another picture of how, I believe, the rear lifting bar is positioned on the rear lifting arm, viewed from the right:
