    Default front-mount brush cutter

    I would like to make a front-mount quick-attach brush cutter for cutting willows, brush, etc. I am thinking of either using an old rotary cutter and modify it so that it will be hydraulically driven. I'm not sure if my hyd pump will drive it but may consider a 3. pump or something else. I'm also wondering if a circular type blade would be more effective than the sling blades of the rotary cutter. It is hard to cut willows and some brush w/ a rear mounted rotary cutter and there are some places you can't go w/ it. Has anyone done this or does anyone have ideas. By the way, my tractor is a Branson 3820i. Thanks!

    What is you pump output in GPM's. I found it. It is 8.4 GPM

    Here are some alternatives.

    Look at the offerings from Bobcat and similar companies. There are multiple brands of rotary mower that fit skidsteers and compact track loaders. I know they do, use a lot of GPM... like 20+GPM

    Thanks for the info. J.J: I like the pictures you provided. Do you have any info about them? The Bobcat brushcutter is neat but it doesn't seem like my little tractor will run one.

    Possible a hydraulic motor could replace the gearbox on 3pt mower, then mounting added to run off the loader arms? Go with a smaller used mower as a starting point. Still, would need an auxillary pump, maybe PTO pump.

    One other possibility is to buy the front mounted rough cut mower from PowerTrac. A 60 inch brush cutter T3021 is only $1500 with the PT mount and is already rigged for hydraulics. You'd just have to weld the PT mount to a QA mount, get some hydraulic lines run under the tractor to your rear remotes and you'd be ready to go. You might need to check on hydraulic output with the Branson but I'd imagine it is close to what is put out by the T12 machines from PowerTrac which are 30hp machines.

    His tractor only has 8.4 GPM's. That just might be enough to run a 3 to 5 cu in hyd motor to turn a 20 in blade and do some serious work.

    The 60 in deck from Power-Trac, needs about 12 GPM.

    You can go into the Tech help on the Surplus Hydraulics web site and do some figuring and comparing some hyd motors that will work with what you have. Select calculators.

    Yes, he could power the 48 in mower on the front. It only needs about 8 GPM. The hook up would be similar to how the PT operates the mower. They have the rough cut and the finish cut mowers.

    PTO pump would also work. Just depend on how much money he wants to put into it.
