Belt driven or hydraulic cutter heads

[Ian C]

2250, Built like a tank, its worth going to global if only to look at the tackle they have got, some cool machines.

 

Is that the 27hp 2 wheel drive one?

Not convinced, have used both and the power loss on the hydraulic grinders is not acceptable, its like stirring mud with a stick. I also cant accept the high wear rate of the drive motors or pumps nor how all that debris from the associated wear gets trolleyed around the entire hydraulic system. I had a guy here a few years ago that had rather a lot to do with the development of a well known brand of hydraulically driven grinder, we were talking spanners and comparing notes on some stuff going on here and he confessed that there were issues with longevity and that their own hire fleet were in trouble with the above . Belts , bearings and most of the horses at the wheel for me

If we're talking about the same line of hydro drive grinders, the motors are horribly under specified for the duty cycle required.

 

The Bandit grinders are much better engineered imo, but there is no way around the power loss over a belt drive.

Yes, apparently its the last 1 global will get as they are bringing a new model out 2250r which from what i can gather is pretty much the same machine but with stuff moved around to give it a low centre of gravity and a switch to engage the cutter head instead of a lever. The 2550 looks like a beast of a machine but too big for what we need.

Yeah have had a go with one, thete ok but go to heavy and you will loose power fast, well built as all bandits are but the power loss will take it down to the equivalent of a 20 ish hp machine wich is a big loss.

I can do that with our belt driven carlton though, surely its about working with the machine not against it, plough it through the soft snotty stuff when the goings easy and steady away on the tough stuff. My m8 insists on ramming the cutter wheel into the stump to the point its towing! in this instance i probably have more horse power with an axe

[Ian C]

It is but you loose power faster, hydro heads just don't have the grunt.
