Increacing horsepower on wd 45

My Dad and his neighbor used to farm together and both had WD45's.  Dad pulled a 4-14" in 2nd gear and Homer pulled 3-14" in third.  Homer argued that he could plow more acres/ day than Dad.  So they were plowing in a 1/4 mile field and they worked on different sides.  That afternoon they counted rounds each made and figured the furrow's turned.  For each hour they plowed Dad had 2 more furrows turned.  He also burned less fuel.  I remember Homer was REALLY surprised.  Larger equipment even at a slower speed is hard to catch up to.  

Seems like a lot of work just to prove a point, but here's what I would do if it was my tractor and my money. Start with the chassis.....rear tires in very good condition( preferably NOT Good-Years)  and 14.9 x 28 size full of fluid.....a couple extra wheel weights on the left land wheel.........you have a loader??? great....leave it on and locked at a height about three feet off the ground..........make damn sure the "Traction Booster" works and you actually know how to use it. The engine with just a set of AGCO OEM D17 pistons and sleeves and a good valve job (nothing fancy at all) and a D17 governor spring will provide way more than enough power to work with your already prepared chassis. You will need to convert to 12 volts to get it started. A reground crankshaft with new mains/rod bearings and cam bushings would be smart as well to maintain proper oil pressure when hot. This engine combo could then be used after the spanking you're going to give the MinnieMo for other things on the farm and still use regular gas. Oh yeah....be sure you have a new foot clutch with the 9-spring pressure plate and a 3-disc hand clutch that is adjusted for a crisp "snap" so nothing slips under load. Be careful when doing heavy PTO work as this engine set-up is capable of ripping the gears out of the PTO. Make sure the fan belt is new and tight and the radiator is clean.....you'll need it to be in tip-top shape to keep cool.
