i think the tower bit is removable, makin ut fairly easy to switch hit
i believe that the tower is removable or at least collapsable
They have pictures of the mountings it doesn't look that easy to remove the tower portion to me without another machine to lift and set it down. If you're dead set on doing cable steep ground I'd wait and see what the tethering does to the tower stuff with a few way to yard steep ground now you never know what the government will push next. And on the cab yeah Oregon requires a forestry shovel cab for brush work not landing though for older machines.
That's always a fun deal to do, if you have time build a pin pusher and the plans for them. Does she have rock guards?
The pusher I've used were 45 ton Porta powers the other a buddy had was 100 ton if I remember right, most of the I used a good solid drift welded to a length of pipe as a handle. Rock guards are more or less just to keep the tracks from throwing off the rollers, sprockets, and idler it'd be well worth building a set or at least a few length of them.
Once you heat them and beat on them for a while you'll see why, most of the time I get a spare pin or two so I can hollow out the pin it seems to help. Just for giggles make dang sure those rails are stretched enough before you pop a pin out. All the years we've had machines we've never broke a pad we reuse them on the next set of rails when we do UC.
