I'm not sure how much you know or don't know already
Well, I'll give it a try, at least with the Whirlpools/Kenmores.
Front row of the "Shed Machines" photo from left to right.
Whirlpool (Wssher #1): This is one of the first 27 inch Direct Drive model which probably was issued in 1986 and 87. It has the clothes guard ring, and is one of very few DD model Whirpools with the plastic lid handle. It was 1988 when Whirlpools started cutting out a notch in the lid well similar to that of a Maytag. The agitator is a Surgilator, although it looks almost nothing like it's Belt Drive predecessors.
Kenmore (Washer #2): This is a 90 series Direct Drive Kenmore. This may be the 2nd model down from the TOL models which had electronic controls, but I am thinking this could be the 3rd. I do not see the Lady brand on the console, but I have low vision, so I could be missing it. The basket appears to be speckled, and that is throwing me; as Ladies and at least the models right after them have white baskets. This washer was issued somewhere in the 1987 to mid 1988 time frame. Notice in both this washer and the Whirlpool I just detailed, the tubs have perforations only in the lower 2/3rds. The top 3rd is solid, and it was around the fall of 1988 that models with fully perforated tubs made their debut. The Dual Action agitator looks like those of the Belt Drive Kenmores, except the shaft is shorter, and the base vanes do not look as long.
Whirlpool Convertible (Washer #3): Unfortunately I cannot tell you too much about this washer, but I am guessing this was a mid 80s machine.
Whirlpool Ultimate Care (Washer #4): Direct Drive model from the 1999 to 2003 time frame. It was around 1999 when the hole pattern changed, virtually eliminating 50% of the perforations in the tub. The Dual Action agitator has a slight difference in the spiraling shaft vane, and is equipped with a sensor that enables it to rise above its stationary height in order to enable rollover of large loads.
Back Row left to right:
Whirlpool (Washer 1): 1981/82 model with the famous and equally effective Double Duty Winged Surgilator. This was given the name because of the three giant petals protruding from the agitator skirt. This model has the agitator mounted softener dispenser, which if I am correct served as the agitator cap. One thing I find interesting is that this model appears to have a manual cleaning filter, yet the model describes the filter as being a Magic Clean, which I always understood to be a self cleaning version.
Whirlpool (Washer 2): The LDA5800Y1 is from the year 1976, and is a true classic with the traditional Super Surgilator. This has the manual cleaning bed of nails type filter, and the largest capacity of the Whirlpool/Kenmore lines. The tub in this washer is actually larger than the BD Whirly I just discussed, but only by very little.
Electronic Control Kenmore (Washer 3): TOL model from the early 1990s I assume. It does not bear the Lady Kenmore name, which is telltale. I am not entirely sure when the Lady name was last branded, but it had to be no later than 1990. This model does have the fully perforated tub.
Whirlpool Calypso (Washer #4): A new and unconventional, and innovative washer design and wash method where clothes were bounced and spun onder a continuous cascading waterfall. These did not last long on the market. Consumer reports once described the agitator-like object in the tub as that which "resembles a giant juicer". They were right. We had a juicer that looked just like that, but the vanes were straight, whereas the ones in this washer are swirled
Maytag Dryer: Mid to late 1970s 06, 07, or 08 series model with the larger door. Couldn't tell you a lot more.
I am sure others on the site will provide more info on these. You do have a nice collection.
Have a good one,
James
