I have an M&W 400B like the one pictured. These work by operating a hydraulic pump. When you turn the load wheel, it begins to close a valve that restricts the oil flow and builds up pressure. If you load the tractor to its rated PTO speed, then you can read the horsepower directly off the gauge, since it is calibrated to convert pressure to horsepower at PTO speed. If, however, you want to check the horsepower at any other speed, then you have to read both the RPM gauge and the pressure gauge and line up those numbers on the side rule that comes with the dyno. The horsepower is then read from the slide rule.
The "horsepower gauge" on the dyno is only accurate at rated PTO speeds of 540, 720, or 1000. If you want to know the horsepower at higher or lower speeds than the standard PTO speeds, use the two gauge readings and consult the slide rule.
The water hose is for cooling the hot oil and it goes through a radiator inside the oil tank. The oil gets pretty hot when you have the load cranked down. There is a manual flow valve that lets you adjust the water flow to keep the oil temperature in a certain range.
The dyno should be hooked to your hitch for stability. Not only that, if you're cranking enough horsepower, the dyno can lift a wheel. We set a loader bucket on it to hold it down.

Today's Featured Article - Grain Threshing in the Early 40's - by Jerry D. Coleman. How many of you can sit there and say that you have plowed with a mule? Well I would say not many, but maybe a few. This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
