Farmer George's Review. I farm and used this on a heavy 14ft offset disc. This lasted almost 4 hours before the end that the hose was attached to came loose. 1/3 of the final casting broke off. I've never seen any of them fail like that. My clerk pulled the end out of the old manhole that was failing and installed it on this one. Since then he has worked on 250 hectares. Not sure how long that will take.
