Just wondering how much plow I can pull---have a massey 45 hp. 4X4 diesel tractor and want a plow---I have pasture that has been sub-soiled and needs to be plowed before tilling or disking---what can I pull???

sandy/loamy type soil.
Engine hp or pto hp? In "the good ol' days" horsepower of a farm tractor was generally spoken in terms of pto hp (or belt hp before that) Those were the days when plows were common also.
45 ENGINE hp will play out as 38 to 42 pto hp most cases. That said, 45 engine hp will EASILY pull a 2-bottom plow in just about every concievable condition. If propely ballasted, and mfwd traction is included in the mix, 45 hp MIGHT pull a 3-bottom plow in sandy/loamy soils. Some consideration must be given to WHICH plow (brand)
12", 14" or 16" plows are each different animals too. Plows work best at a depth of 1/2 their bottom width. (i.e. 12" @ 6" deep, 14" @ 7" deep, 16" @ 8" deep) A 3-bottom X 12" plow moves less dirt per pass than a 2 X 16" plow IF operated at the intended depth. We need to keep in mind that most soil conditions ARE NOT consistant at varying depths. The dirt at 8" down might be harder than the same ground at 6" deep. We aren't plowing a "text book". Conditions of soil structure and type must be considered.
Different brands pull harder or easier than others. The new HOWSE plows (available at TSC) pull like an anchor compared to a Ford 101, even though they share replacement wear parts. John Deere plows pull harder than any brand due to angle of the share and contour of the moldboard. (They also tend to perform less favorably compared to other brands in some conditions like plowing sod.)
The "better" 3-point mounted plows IMHO? Ford 101's, Massey FErguson #43, #66, (#74's in CAT II version) Any Oliver/White plows are good but parts are getting scarce.
I'd opt for a 2-bottom plow in your case, increasing plowing speed if you find adaquate hp and traction. Test's by several manufacturers in the 1960's made it evident that using smaller implements at higher ground speeds would (a) accomplish same (or greater) results and (b) prove to be more fuel efficient. And as an added benefit, smaller than maximum "load" is easier on the tractor in the long term.
