Dave, for question #2, my canopy is 58" front to rear and 48" side to side. Weight and ease of installation? Don't know the weight but saw a relatively small mechanic at the dealership pick one up, set it on a new L series Kubota and hold it with one hand while he put the bolts through the brackets. He did get a second person to hold it straight while he tightened the bolts. Vibration noise? None! Warranty? Never even thought about it; have no idea. I have the steel painted to match the tractor and after nearly 2.5 years, they still match./w3tcompact/icons/wink.gif You can also get unpainted diamond plate aluminum for the same price. And it came with a real nice black molding around the edge, but after I scraped it loose on trees about 3 times, I just removed all of it./w3tcompact/icons/frown.gif It definitely takes a good hit to bend the edge and it's tough to straighten when you do, but the frame and brackets have never moved.
