| I want to set up a dolly to pull a flat bed semi trailer with a farm tractor. I was thinking of running an air compressor with a hydraulic motor so I could just plug in hoses to whatever tractor I used. I was wondering how big a hydraulic motor an old combine reel would have and if that would run a 5hp air compressor. I saw a portable gas air compressor advertised that does not run and considered this idea.
My plan is to run one line from the air compressor to the emergency line on the trailer and then run another line to the tractor and then back to the service line on the trailer. When the line comes into the tractor, I plan to put a valve, regulator, and two gauges on it. I want one gauge before the regulator and one gauge after it. Then I plan to set the regulator for just enough pressure to activate the brakes as aggressively as I need once I turn on the valve. | |
