A Sherman transmission will give you 2X the amount of gears HI-LO in first HI-LO in second and so forth. Then there are other variations I no nothing about. Richard

There are several Sherman transmissions. They are all add-in aftermarket transmissions that fit in the space betweent he clutch and the regular transmission. The most common version is a Hi/Lo 2 speed underdrive/overdrive box that also has direct through, giving you three options for every transmission speed... in effect, this gives 12 different speeds forward and 3 reverse. Seach for the John Smith site (on 8N fords) and you will find lots of information.. Jim in OH

Let me answer a bit more completely....The Shermans were installed in the housing/void between your clutch and the main transmission. They replaced the original input shaft/assembly and effectively 'split' the main transmission to change groundspeed AND PTO speeds. (your pto is transmission driven so changing the speed of your trans changes the PTO speed by the same ratio). There were 'overdrives', 'underdrives', 'Combination(O/D & U/D', 'Creepers', 'reversers', and a 'planetary' overdrive. ALL of the types had the standard range of gears as well as their specialty range so you had 'High/regular', 'Lo/regular', 'Hi/Lo/regular', 'reverse/regular', etc. ONLY the 'Combination' should be called 'Hi/Lo'. The O/D & U/D versions could be either handle shift or cable shift. ALL of the handle shift models exited the housing via a drilled hole in the LEFT side of the tractor. There were several other brands beside Sherman, and ALL of these were handle shifted out the RIGHT side of the housing.
Hope this helps you. Post back or e-mail if you need more info help,

jim

Naa.. "Sherman" means Eber and George Sherman who were buddies of Henry Ford and Harry Ferguson... Ferguson/Sherman were mostly into supplying "implements".. most significantly the plow (or plough depending on preference)...

Left to right they are; Harry Fergusen, Henry Ford, Edsel Ford, Charles Sorensen, George B. Sherman, J.L. Williams, and Eber C. Sherman.
