I have an oliver 1850 with 18.4x34 tires that needs replacing. I am thinking on replacing them with 15.5x38s because then I can use it more easily to pull my 4 bottom 14" trailer plow. Currently , I can't use it for that because with the 18.4 tires, it won't sit down in the furrow when trying to plow, but with the 15.5 tires, it would. I have a JD 730 that I have been using to plow with, but I would prefer to use the Oliver if I could.
My question is, will I loose pulling power on the Oliver by changing the tires to the 15.5s? I also want to continue to use my oliver to pull my 12ft culti-mulcher and 12ft disk which it currently does without a problem.
