Learned from experience,
An "A" tower welded to the lower track wheel guards to support the hydraulic lift cylinder is NOT the way to go - the guards are not strong enough to handle the pressure.  See photos of my AG-6 with an otherwise decently mounted blade.

How many different colors were used on the Cletracs?  
Has anyone developed a listing by year and model, with color and paint codes?
Could we pool our knowledge and put one up on this site?

Is there a track interchange listing?
What models shared tracks?

I was working with my AG-6 on a hillside this past weekend, and sure could have used a footbrake!  
Between the throttle, 2 hand brakes, and the gearshift, it certainly was a challenge.

I use my AG-6 now for light landscaping duties, and trail work around the treefarm.  It took a bit of work to "bring it back" over the past 5 years.  On some of  my other vehicles, I'd say I'm doing a "rolling restoration", here I definitely can say it is a "crawling restoration"...
