    Hydraulic motor power vs speed

    Sorry this is not on a tractor, its on a boat. The hydraulic power unit is run from a 9 hp honda. I thought about the log splitter pump but I am running a 5 spool valve which also controls the boom cylinders. The entire system works good now other than it takes about 15 seconds to pull in 20...

    Hydraulic motor power vs speed

    I'm trying to compare motors with quite different displacement. A 23 ci/rev 4500in-lbs motor which turns at 150rpm gear up to match the speed of a 5 ci/rev 1500in-lbs motor that turns at 750 rpm. My application is I have a winch made with the 5ci motor and it is geared down with chain and...

    Hydraulic motor power vs speed

    Generally speaking, if a larger displacement hydraulic motor is geared up with chain and sprockets to achieve the speed of a faster smaller displacement motor, will it still have more power (torque) than the smaller motor?

    Loose loader control

    I have a TN75 and the loader control has a lot of play. Top moves side to side 6". How do I tighten it up. Dealer says replace it at $800.00 Not happening.

    Polyethylene seem welder

    The price is reasonable, doesnt need to be strong as the mussels grow into the mesh within a few days which supports their weight. Worth a try, I wonder if it would be possible to increase the temperature as the mesh may require more heat than a polyethylene bag
