T20 shuffle

[rcn11thacr]

I've got over 1k hours driving time on tanks with latteral steering while in the army. I've got 4-6 hours driving time on my 07 max iv with zero problems driving it. Never heard of a "shuffle" needed to drive tanks (or at least not in that terminology). Someone take a moment to explain the process of the T20 shuffle please.

The shuffle is pulling back and releasing on both sticks with one hand several times quickly while shifting with the other hand. You are basically acting like a synchronizer. The ATV will roll slightly while you do this or the clutch will turn slightly, allowing both sides of the transmission to shift.

A video may help. I'll link directly to the time:

Thanks Mike. I figured that was what was meant, just wanted verification. Thanks for the video link

I just reworked my T-20 with the 9 tooth selector gears and seams to shift easier than the 18 tooth setup. Any body else notice the difference in the trans models? My Hustler always shifted better with the spring loaded linkage than the Maxes.

MaxIV Mark mentioned how much easier my IV was to shift than his. I have an supported shaft unit and homemade linkage vs his newer unit with factory linkage.

I think the 9-tooth models do tend to shift easier. I'd have to take them all apart again to recall which machines have the 'Niners, but I notice it when I do shift them. In my opinion, a well adjusted and lubricated Hustler EZ-shift spring-loaded linkage is the easiest to operate. It's still a little ornery from time to time, but in lieu of a split shift, it's a good setup. I've been testing the Newt the bold frame out a bit, which has a split shift. In a heavy machine, the T-20 shuffle transforms into a Cirque Du Soleil act, even with a split shift. I wonder how Admin-Mike's Avenger will shift...

I think there is a point to leave slack in the primary chain. Maybe a chain adjuster that pinches the chain with spring tension but still floats.
