M1A1 Power Cable
The AFV ASSOCIATION was formed in 1964 to support the thoughts and research of all those interested in Armored Fighting Vehicles and related topics, such as AFV drawings. The emphasis has always been on sharing information and communicating with other members of similar interests; e.g. German armor, Japanese AFVs, or whatever.

I noticed a couple of M1A1 tanks with a power cable coming out of the driver's hatch from where the right periscope normally is. They were long enough to go maybe three feet past the headlight. Anybody know what they are for? Thanks! _________________ "TUMBLEWEED"

Bob's right, the original mine plow power cable snaked through the right periscope opening. It eventually was upgraded with a plug that fit in place of the periscope so the cable would plug into the fitting and not have a gap there. The M1A2SEP has an external power recepticle that negates the need to sacrifice a periscope.

Don't let folks tell you the mine plow is hydraulic.

Thanks Rob. That clears it up. I was thinking they were hydraulic. The other thing that threw me was that older tanks (I think) had additional hardware welded to the hull for the plow. _________________ "TUMBLEWEED"

If you look at the front of the mine plow, towards the top there is a large cylindrical object on each side. This is a simple electric motor. The power makes these motors rotate and it raises or lowers a webbing strap (similar to a seat belt). That strap on each motor is what raises or lowers each mine plow side.

The straps are susceptible to dry rot out in the motor pool and are always snapping.
