    Default Branson Trailer 4720i (47 hp)

    This tractor thing is all new to me.
    I just bought a larger piece of land and wanted to get a tractor . After an long search I bought a Branson 4720i (hydrostatic) with a hoe. Not sure if I am driving it correctly or if there is a problem with the unit. Seems I run the throttle at 1500in low gear most times Seems any small incline the tractor wants to stale on it. RPMs goes from 1500 down to 500 She continues to climb it but its not a big hill by no means and is me and the hoe . It works better with out the hoe on the back but still has some problems It has yet to stale but is very close.
    Yesterday I tried it at 2200 RPM engine was just screaming and was even worst . Any ideas?

    You're not the first new owner to make this mistake. Get used to the "screaming". If you think you need ear protection, so be it. Tractor work is done with torque, and you need RPMs to develop that torque. Lugging the engine is unproductive, wastes fuel, and exerts undue stress on expensive components. There should be a mark near the upper end of your tachometer to mark the point where PTO revs are being developed. This is both the most productive and the most fuel efficient operating range for the engine. And even though it might be counter-intuitive, wear and tear is at a minimum at speed as well. It's just how they're engineered.

    Sounds like you don't have the tractor manuals, I strongly recommend you invest in and study a set. Pretty sure Branson tractors are Korean by the way.

    I concur with Greg. My Mustang is hydrostatic drive and the engine speed has to be in the operating range.
    Get the manuals, they will tell the story.

    I have the manual . Too bad every second word is spelt wrong. Manual is very poor. The dash does have a PTO 1 and PTO 2 mark.
    PTO 1 is 540 ?? and pto 2 is ?????
    Update 1800 rpm says 540E PTO2 Not sure what that means ?
    2500 -2700 RPM is PTO 540 1 mark

    It has a two speed PTO and at 1800 rpm pto 2 is at 540 rpm while pto 1 would be much slower. Your engine is designed to run at about 2500 rpm to develop full torque and 540 rpm in the pto1 position. There should be a lever to change the pto setting. Most al US implements are designed to run at 540 rpm pto speed. Your engine is designed to run at 2500 rpm for ax efficiency and power.

    The PTO's are 540 and 720 r/m PTO shaft speed. The 1,000 r/m PTO's have twelve splines.

    Will try to get a pic of the console today Both marked areas say 540 PTO.

    Looks to me as though your PTO has the customary two speeds with neutral in the middle, just that they're labeled 584 and 790 rpm, versus 540/720 which is standard. That is probably what they have calculated, based on their recommended engine rpm of 2500-2700. So I'd say run the engine at about 2500 rpm.

    I'd like to add to Rich's post with my interpretation of the two PTO speeds on the tach. The #2 speed ~1,800 r/m is for stationary PTO driven implements that do not require tractor propulsion: ie. log splitters, generators, chippers, etc. The #1 speed ~2,500 r/m is for implements requiring power with the tractor in motion: ie. rototiller, brush hog, etc.
