I have a nh 1920, purchased used from a dealer in florida. I bought a 'last in stock / old model' canopy for the tractor.. was diamondplate, with a fiberboard pad, and attatched to the rops. I had it added to the tractor before delivery, and the NH dealer charged me 280 for the canopy, and the salesman got them to put it on for free. ( like 280 wasn't already enough.. <G> )
I like it... have never had a problem with it... Doesn't vibrate like some plastic and fiberglass models. I also have had a buggy style canvas over tubing canopy that I had on my little yanmar tractor... blocke dthe sun out good, as it was dome shaped... but would have crushed up real nice in a roll-over situation.....
