Morning Charlie and Eric.

Did Mack ever have a power option? All the ones I have been around were painfully slow...

They go pretty fast in reverse Bill.......

The one Mack Superliner I used to drive rock-n-rolled pretty good but that had a 425 Cat in it.

When I worked in prestressed concrete I got to drive the yard tractor a couple times. I can attest to that "fast in reverse" thing lol

The trans I have in mine, I have 6 speeds for reverse. :D

Time to get something accomplished but I'll be back shortly. Try to play nice now.... :-X15

I forget the specifics of this one...it was a dog though.

Play nice? Where's the fun in that...?

Even the visions I drove used the 5 speed for reverse. had a button on the side kicked it in reverse.
Nothing like the old 2 stick in the B's and R's tho, that was a blast. shift all day and get nowhere

Probably a 2 stick Bill. rt stick was a 5 spd, left stick was high/low / reverse

The U-model I drove was the same way (twin stick). Didn't get anywhere but rolled coal like crazy too!

Oh yeah, little 3" stack FULL of black smoke......

Yep and the green painted rock box had a big ole black racing stripe down the side.

ever drive a quadroplex?

Not that I remember.

5 spd 4 spd. same as the mack duoplex, but 4 speed instead of 2 speed. Usually came in detroits. crains, excavators, early gradalls etc. Lotsa fun....LOL

I don't believe I did but I do remember the tranny.
