<strong>MASSEY</strong>-<strong>HARRIS</strong> TRACTOR ENGINES<br />

Deliver smooth, economical power<br />

Here's the heart of your Massey-Harris tractor .. .<br />

peppy, quick-responding engines that develop more<br />

power, more economy than any in its class. There's<br />

smooth, flexible power delivered by your Massey-<br />

Harris . . . L-head or Overhead design each measures<br />

up to the highest standards of engine efficiency. You<br />

have dependable power, constant power that turns<br />

that last furrow with time to spare.<br />

High compression in your Massey-Harris means a<br />

cooler-running engine . . . extra power for occasional<br />

STRAIGHT-LINE TRANSMISSION<br />

SAVES POWER<br />

* Massey-Harris transmissions are precision-built. Power<br />

moves in a straight line through the gears to the final drive.<br />

There's no lost motion . . . no power-consuming side<br />

tracking. Gears arc machined accurately for a full-rolling<br />

contact . . . case hardened for extra toughness, long-life.<br />

Heavy ribs in the transmission cases provide maximum<br />

strength with less weight. Shafts are short, husky . . . to<br />

eliminate flexing, take shock- loads easier. Heavy-duty<br />

bearings last longer . . . run smoother. Oil-bath lubrication<br />

positively protects gears, bearings and shafts.<br />

Speeds are determined after exhaustive tests under<br />

varying conditions and are job-matched to each tractor<br />

model. The Pony has 3 forward speeds; "22" - 4 forward;<br />

"30" - 5 forward; "44" - 5 forward; "44" Diesel - 5 forward;<br />

and "55" - 4 forward.<br />

tough spots. Cylinder block and crankcase are cast in<br />

one piece . . . ribbed for more strength. Crankshaft is<br />

statically and dynamically balanced for true-running<br />

. . . smooth, vibrationless operation. Pistons are long<br />

lasting . . . fast lubricating. Built-in governor and automatic<br />

spark control give top economy on every job.<br />

Manifold is cast and machined in one piece for positive<br />

seal to engine. Valves, rods, bearings, crankshaft<br />

—all are husky, extra strong for years of plus-power.<br />

( "44," "44" Diesel, and "55" have removable sleeves. )<br />
