Today I just bought chain-on loader forks for my NH 16LA with HD bucket. There is a bracket which fits over the cutter lip and a chain goes behind and over the top of the bucket and attaches with a "boomer" for easy and quick assy/removal. These forks are rated at over a ton and are manufactured by a company in Colorado. At my New Holland dealer, the cost was $280. I tried them on brush (large tree trunks) and moved several telephone pole sections (5' to 25'). The hardest thing about them was getting used to being 4' longer and the magnified movements of something so far out in front of the bucket. I absolutely think they are worth the money and I can install and remove them in about 30 seconds. If you are interested, I can send you a digital photo attachment.
