progress. When Red came into the shop, it did not have power back. It was a pull back. The crew went went through a couple of ideas, originally the "tower of power" was going to be used but determined that the operator would be too high and the center of gravity shift might cause problems. So, the cradle was cinceived and built. Finished up the drive tonight. Testing the unit is on the horizon.

Had to call a last minute audible when it came to the box clutch. We needed more clearance to let weight box move back an additional 5 inches. Which is a mile. Mounted it between the drive axle and the transmission. Just squeezed it in.

Keep working with Mean Green Pulling Sled on the Angry Red project. Have a drive pulley that wasn't exactly what was needed so machining a taper into the bore to fit a QD bushing in it. And we tyrned our arts and crafts project into a reality. This is the quick change box drive transmission. There will be options for the box to top at 263, 280 and 296. (If my math is correct) and for those of you that think that they should ha e called the "professional" tractor pull transmission builders, well they did and one told them "how the hell should I k ow what you need" and the took all the information needed back in January and never called back. So here we are. Go team!

Doing work for the Mean Green Pulling Sled group. Some of it included arts and crafts but that is still productive (most days).
