I spent this afternoon grading the inside of a new building with my plow tractor featuring the modified hydraulic control lever.
What a difference! Never a moment of hesitation or thought when operating the blade. There is something that smooths out the flow of motion when it is applied in the same direction. What an unbelievable difference.
If you use your cub for grading or snow removal and have the same difficulties I had operating the hydraulics, I give this modification a very high recommendation.
I don't know what made the systems' backwards operation so difficult for me. I never forget to open the gas valve, shake hands with the shifter, or close the gas valve when I'm done, but move the hydraulic lever in the right direction the first time? Never happened.
