Just bought a 10-152 2 bottom Ford plow in fair condition and have some questions if anyone could help me. Is this considered a economy plow? I have moldboard covers on one moldboard but not the other and the parts manual shows none, which is correct? I see Farmwithjunk has moldboard covers on both bottoms on his rebuilt plow. Also I have a Kioti LK3054 and from outside to outside measurement for the rear tires is 52" which the manual says is correct. The question I have is where should the first bottom position be compared to the right rear tire? Thanks in advance for any help.
The term "Economy" plow had more to do with the style of bottoms. Some had a moldboard and a share. The leading edge of the moldboard formed the shin. Some had a seperate REPLACABLE shin along with the moldboard and share. The version with the replacable shin were called economy bottoms when they were first offered. They became popular and were widely accepted. The share and the shin take 90% of the wear. Replacable shins allowed moldboards to remain useful for a much longer time. That saved the farmer a few bucks. (hence, ECONOMY...) The old style 2-piece bottoms became obsolete and were eventually dropped from production.
Cover boards (trash boards) weren't real common back in the day when that plow was new. Odds are it was an add on aftermarket part. Normally, they would be found on both bottoms, or neither. If I was to guess, someone might have put just one on the FRONT bottom to help prevent the plow from plugging when plowing in "trashy ground". (ie stalks, tall weeds, crop residue present) I prefer a plow with coverboards. They do a MUCH nicer looking job when plowing in sod, or with surface crop residue. A very popular brand of aftermarket coverboards was YETTER. Their version was usually made of black plastic.
Done CORRECTLY, the TRACTOR's width is adjusted to fit the plow, and NOT vice versa.
Outside tire width can be misleading. Plow manuals usually list that for a specific tractor model/brand. (with a known tire section width) In MOST cases, older plow manuals will be speaking to tractors with narrower tires/wheels than are common today. Many plow manuals will also list "track width" (center of tire to center of tire) But the most USEFUL measurement will be centerline of tractor to INSIDE of sidewall OR INSIDE of tire to INSIDE of tire.
To determine INSIDE measurement for the plow you have, take the total cutting width of the plow, (ie 2X12" would be 24", 2X14", 28", ect.....) The center of draft line is usually 4" to the left of 1/2 that measurement. So....a 2X12" plow's center of draft is 16" from the RIGHT side of it's width of cut. Now, add approx. 1" to 2" to that. That will give you a good centerline of tractor to inside of the RIGHT sidewall measurement. (That center of draft line wants to be in line with the center of the TRACTOR when the plow is in the ground) With that, a typical 2X12" plow would want 17" to 18" from center to inside of sidewall. A 2X14" plow would typically require 21" to 22" from CL to inside of sidewall. SLIGHTLY more than that is preferable to SLIGHTLY less.
The plow SHOULD run where the lead bottom's full cut is just to the inside of the right tire's sidewall. And with that, the 3-point top link should be running straight in line with the tractor's centerline.
Confused now?
