The JD Hydro Oil dye is especially handy in the winter. Often when backing up while plowing, you will leave a trail of drops on the pavement, which are usually water drops from snow melting due to exhaust, etc. But when you have a hydro leak, you also drop the same drops. Having them red with the dye has made seeing the leaks much easier. I can't tell you how many times with the front quick hitch I would bend or break a 90 degree fitting on the angle cylinder on the plow and it makes spotting the red drops MUCH, easier........Before the dye, I would get off the tractor from time to time to make sure the drips and drops weren't a hydro leak. Now, no need unless you see the blood trail.................from the dye.
Also, the 1 series shoots the exhaust at the front hitch area and between a top flap on the plow and the exhaust heat, no ice forming to bend the 90 degree angle cylinder fitting to cause the leaks..........On my 455, I bent the fitting so often, I kept 4 in stock. I have yet to damage one on the 1 series even after 300 hours of snow plowing..........
