One thing which I would like to add to Roys video Make sure you close your Hydraulic Cylinder lockout valve as well. That way you are not diverting Hydraulic fluid to the Hydraulic Cylinder that operates the rockershaft on your tractor.
Great Video Roy:thThumbsU
Thanks Roy!! I needed to know how it worked and you pulled through like you said you would. That is super easy to use. I was worried it would be tough to do. A 10 year old could do it. Very well engineered product.
