Please Help! I have a 1973 John Deere 450B Dozer with a 4 in 1 Drott Bucket. The Issue is while I am Using the Hydraulics the Dozer Runs Fine has all the power needed, But when the Hydraulics are Not in use the Dozer Bogs Down almost to the point of stalling out the Motor. Can anyone help me out with this
problem??

That sounds like the hydraulics are dead heading. Did it have a backhoe on it? If so, are the hoses that went to the backhoe connected together? They can be plugged or not connect together if they have quick couplings, unless there is a diverter valve in the system.

Thanks for your Reply! Yes it has the hoses for the backhoe and they are connected together, the thing is this just all of the sudden happened as I was driving the dozer through the field to get to another location, I noticed it was starting to bog the motor down. I didnt adjust of move anything it just happened?

The connectors could be worn and slipping apart a bit.
