advice on low flow attachment for kubota M59 front loader hydraulics

[kolbster]

I have a 2010 Kubota M59 with backhoe and am looking at getting some attachments given I have hydraulics to the front end loader. By the specs, the flow rate is 16.1. Any advice if I want to get
1) a rock grapple bucket
2) an auger
3) a front end brush cutter

That rating is prolly at rated engine speed. with your grapple & auger you'll prolly be working with your foot throttle at low rpm's & you'll be fine. In skid steer language, that most of these attachments are made for, 16-20 gpm is "low flow". High flow SS's have upward of 30 gpm's.

I think you'd have too low of flow for a brush cutter and also have a problem with the oil getting too hot for continuous operation.

You can get a PTO driven pump to drive a rotary cutter, they are around $3k.

Or use a standard brush cutter on the 3pt/pto. The 3 point setup is the biggest advantage an M59 has over a full size machine.

The M59 can drive a front auger just fine; several of us on here have one. Just be sure you size the auger to the flow rate. The rated 16.1 is the maximum, but is probably not far off the mark for an auger which is not likely to be run continually. Front grapple is no problem at all of course since it does not care about the flow rate.

Hyd flow in GPM essentially means speed.

So you adjust the engine rpm for the flow to the attachment.

You can fine tune the flow by using a flow control such as this.
