I recently acquired a Dynahoe which had been sitting for 10 years. There is no information available other than hy-dynamic on it but I think it is a 190 and square fenders. It has a cover but is not enclosed cab. It is in rough condition but runs and starts easy. I have replaced all of the hoses and still have to have some welding repairs at the base of the hoe where it pivots. After getting it going and being able to lift the hydraulic appendages I drove it a short distance in the yard then the transmission quit pulling. If I let it sit it will work for a few feet. I suspect it is a fluid issue but have no idea about how much fluid it holds or what kind. Some educational information on the transmission and an operations manual would be helpful.
