M59 and the Front Remotes, and a attachment purchase, help needed

buck1974 · Mar 3, 2017

I have ? in regards to front remotes, I read the M59 front remotes have 16.1 gpm flow rate. I was looking around and come across Blue Diamond Extreme Duty Brush Mower that introduced new technology where the flow rate only has to be 16 gpm, and performs as a high flow unit. Usually all these brush mowers require a high flow hydraulic system. However, Blue Diamond advanced the technology to work with a low flow rate system. If I were to run this brush cutter that is rated at 16 gpm and I'm at 16.1 gpm on my M59 would I be in danger of over heating my hydraulic fluid to much running it hours at the time? I haven't contacted Blue Diamond to speak with a rep, but I thought I could get some great feedback and maybe questions I could ask the rep.

I would hazard an opinion and say - as long as the unit is rated at 16+ gpm and the hydraulic radiator is free of debris - you should be OK. The unit wouldn't be so rated if it couldn't maintain that rate. Check the OP manual to see if its derated for continuous operations.

I'm not familiar with the Blue Diamond low flow technology but I would check the operating pressure. Some low flow hydraulic construction equipment operates at 3000+ PSI which many Kubota models can't sustain for long periods. Some low flow rate implements are equipped with built in oil coolers to prevent overheating. By all means, to talk to a dealer and ask a few questions.

Planning on running a rotary cutter up front on a tractor? I've seen several people try, all with unsatisfactory results. PTO is the way to go, much more efficient & much power transmission, not to mention lack of heat & plumbing issues.

I would second this, but I suspect he's "smashing" tall brush down reclaiming overgrown real estate.
fwiw, I have a front hyd. cutter (Ambusher) and "field mower" it is not, on a tractor or skidsteer, but are great for dropping down from 5' on tall vines, brush & saplings.

When it comes to hydraulic power, like everything else, there is no free lunch.

Look carefully at the performance spec's for a hydraulically driven snow blower. The advertising will say it can operate between 12 and 20 gpm.

Great I only have 13 gpm and I can run this blower. The performance spec's, not advertising ones, make it clear you are not getting the same quantity of snow removal at 12 gpm as you would at 20.

The blower bogs down sooner, you have to drive slower.

Every time you convert one form of energy to another there are losses. The engine creates rotating mechanical energy. Convert that to hydraulic, move it through hoses and valves and then, you convert it back to rotating energy. Loss after loss after loss. Looks good having a hydraulically driven blower on a FEL. Unless you have a very powerful tractor, your neighbor with the same tractor and same blower on a 3pt pto hitch will out do you every day.
