Did all of the wd's come with shutters? Mine is a 53 model. The grille shell has the hole for the lever.

I think they did, most were taken off cause they would stick, really didnt need them with a thermostat anyway. Im sure there is a serial number break, but I dont know it.

I wonder if it was just tractor fuel or kerosene models that got them? My 52' had it but I took it off intending to one day repair and reinstall some day. I don't remember if the engine serial number shows it as gasoline or tractor fuel.

I thought I remembered reading somewhere that the shutters were supplied on the kerosene/tractor fuel units, along with the heated manifold, not ALL WD's, but take that for what it's worth 'cause I can't remember where I read it. The grille shells were universal, in that they all had the hole for the shutter crank

No, not even all of the WCs had shutters, even all of the styled radiator shrouds have the hole in the upper right hand corner for the lever. Kip

My '51WD has been in the family since new. It has the straight gas engine. It has the short thermostat housing rather than the longer water manifold used in earlier versions and still pictured in the operating instructions accompanying the tractor. Hard to say whether this changed at the same time as the transition to the tall head from the 3" version. Apparently the tractor was evolving in minor ways more quickly than manuals were being revised.
With a functioning thermostat and good original rad, my WD will not get up to operating temperature under most conditions without closing the shutters at least partially. In mid-summer, working hard on the brush hog, it is necessary to open the shutters fully. The intake/exhaust manifold, by 1951, no longer had the heater box to direct heat to the carburator and it is necessary to keep the coolant temperature well into the green range in order to avoid icing when the engine is working hard. The original design of the WC & WD apparently had a great deal of inherent cooling capability and the shutters remained necessary to keep the engine up to temp in most conditions up north. The WD45 apparently generated enough additonal heat with the greater HP that the thermostat could be relied on to keep the engine temp up.
An operator's manual from the styled WC era comments that units without shutters were provided with a curtain (canvas as I recall) that could be dropped in order to raise engine temp.

Back when I was helping Dad, (1950's) he bought a WD (1949 I think) for me, it was gas and it had shutters. That started my love for AC. It came with a 2-16 mounted plow (before snap coupler), and later he bought a 2 row mounted cultivator for it.

My '51 has also been in the family since new. It is a gasser and has the shutters and the taller head.
