I have noticed on the W-6 that on the engine frame some are a cast and others are channel. Was there a certain time frame that they switched or did it depend on the lant that they were made. Would enjoy your feed back on this,
Thanks

Caseman, the w6's all had the cast frame until the "SUPER W6-TA" in 1954. When they built the TA model, they went to the chanel frame. As with the M-TA's, all '54s were Super W6 TA's weather they had the TA option or not.

BTW, the TA stands for Torque Amplifier. This was a set of planetary gears that replaced the input shaft of the transmission, thus giving two gears in every transmision speed, and was shift on the fly, by means of a clutch that released the planetary housing.

I know I have seen pictures of the W-6 with chanel frame that weren't SW-6TA's. Maybe they were just a SW-6. I will see if I can't find a picture and serial number of one., thanks for the reply,

According to Guy Fay's book "Farmall Letter Series Tractors" the late Super W-6 had a channel frame while early supers had cast iron tub frame.

There is a picture of a Super W-6 LP w/channel frame that he refers to as "very desirable."

Hope this helps!
