Hydraulic stump grinder

[GlobalNewark]

Thought I would post a few pics of a demo carried out this week with a new hydraulic grinder, the machine is 45hp turbo(the same as our 7" chipper). there are a few aprehensions that being hydraulic that this draws to much power resulting in a lot of power loss.

 

I have to admit I was beginning to doubt myself as I have heard this that often but technology moves on & the demo proved that this is a thing of the past.

 

These were very large cedar stumps & were rock hard so a good test, they were not ground in record time but the job was completed satisfactorly.

Looks like a great machine.

Good pics, not enough grinding on here! however old cedars are really rather easy, even a smallish machine will race through them.

Looks a good unit though!

If there are doubts over hydraulics, why bother? Is it cheaper to build?

The cedars were taken down ten years ago but were solid, we all expected them to have softened, on the plus side they smell nice

That's a fair question.

Now I can appreciate what you ment earlier on the phone about the size of the stump, decent bit of timber, wouldn't like to tidy up that mess. Was that the fancy new head/teeth combo or just normal green teeth?

I beg to differ about old cedar being soft, they may look a bit around the edge but the middle will be as the day it was cut down and some seem to get harder, well for about 10 years anyhow.....

I never said they were soft I said they're easy grinding, which they are, they chip off easy, unlike say poplar or cherry, which can be a PITA for the smaller grinder.

you can get better engine positioning as you arent having to line up engine drive with belts,no clutches on the engine, does away with drive belts

Oh yeah, I get it now, good point!

However A lot of the more popular ones on the market are still belt driven.

(believe me I look at a lot on the net)

All about cost I guess. Whilst belts seem a bit medieval they do work well and are cheap.

Anyway nice looking unit.
