Turning Radius, M939 Series: W/O Winch vs. W/Winch

[hendo]

According to the operator's manual for the M939 series (TM 9-2320-272-10, 31 July 2012), the turning radius (TR) is significantly different between models w/o winch vs. w/winch. For example, the M931 has a published TR of 46', whereas the M932 is blessed with a TR of 31' (pgs 2-12,13).

I'm fairly new to the MV game, but this doesn't make sense. I've been seriously considering an M931, as I don't want the winch. However, if the M932 does indeed have such a significantly better TR, that would make it the one to pursue.

Is this really the case or is the TM in error?

The turning radius has nothing to do with the winch. Maybe it will stick out further, but you are really looking at the distance between the front axle and the rears.

Turning radius is the same

Yeah, that's what I figured - unless, for some bizarre reason, the non-winch models have different steering assemblies. It was that or the specs are in error. Before dismissing the manual outright, I figured I better check.

There IS a difference between "turning radius" and "turning circle"-also known as turning sweep. It is different between the two trucks when you are talking about turning circle, not turning radius. I haven't gone and looked at the TM (sorry) but I am assuming from a past life, that the difffernce is in the swept area.

I can tell you what the turning radius of a M927 is........huge.....with or without winch.

Yeah, 46' according to the operator's manual. Of course, if you had the M928 w/winch, it'd be 31'.

That's easy, you take that hook , latch it to a big pole,and drag it around in a tighter circle.
