Need a heavy duty machine

[Stefan Palokangas]

We stump grinding guys should go together and create a heavy duty stump grinder suitable for British demands.

 

That don't break down due to undersized parts .

Didn't someone on here engineer their own machine a while back.

IIRC it was really well thought out and made.

 

I'll offer my thoughts for a specification....

 

Narrow enought to go through MOST gates (not just the big ones) - well under 29 inches.

Short enough to give good manouverability.

Powerful enough to make the faff of transport and unloading worth the hassle 40hp+

Diesel driven for the required torque (and cheap fuel).

Use an engine that is as common as possible - easy spares sourcing.

Maybe longitudenal mount then hydraulic drive to wheel (keep it narrow)

Service parts ACTUALLY easily accessible - not just claimed in sales literature.

 

Is there a small digger narrow enough to buid something on to?

 

There will be loads of problems but surely this is not impossible???

 

Good luck, I'd be happy to chip in as far as my tech knowledge goes.

(i) Seperate Electric or Hydraulic powerpack

(ii) 2 very heavy, hydraulically deployed outriggers,(with screw-in anchors?) for stability.

(iii) On tracks for all terrain access.

i.e. A modular approach, the same (hydraulic) powered stump grinder unit could then be used with breaker circuit off a suitable excavator.

Or not!

Metric bearings and pulleys.

Hour counter that doesn't measure 10ths

A machine that uses more parts common across other industries.

No reason a main kingpin pivot shouldn't be one from other machines rather than a specific and exhorbitant Carlton part.

21st century electronics rather than toggle switches robbed from the 1950's

Indeed parts that's common, and no being forced to one dealer or phone to serbia for parts.

With American machines there is no such thing as a part you have to buy from the main dealer. Within 10 miles of miles of me there are 2 engineering companies capable of making any part of an American grinder or chipper. The rest of the bits are all from other manufacturers, belts, clutch etc etc. You can also bend and weld the rest of it back together because all the steel is so thick.

 

Regarding the original question. Under 3ft wide. Proper high speed tracking, 60hp, really good stability. proportional radio remote, belt drive, chunky bearings, oversize clutch, as short as possible, hydraulic dozer blade, detachable blade that fits over the head so you can blade backwards and forwards. Some way of attaching a hydraulic drive mulcher on the back for light scrub clearing.

Stefan you are going to love our six ton "Dumper Stumper" . Based on a six ton thwaites 4x4 dumper with a shuttle , swivel skip removed and a direct drive 8.3 ltr turbo Perkins V8 diesel ( very compact and loads of torque @a very leisurely 1500 rpm) Running a similar set up to our big Rayco but mounted to the swivel set up on the dumper, should have at least 13 feet of sweep with an augur shifting the grindings to one side. Gathered all the bits bar the wheel ( still doing research on teeth that will poke up with that engine). If Mick Dundee does not go on walkabouts this year we will get it built. No good for Mrs Miggins back garden though

No doubt I will like it, I like strong built

When I bought machine and joined Arbtalk, I was talking in terms of low prices, few pointed out maintenance cost, didn't think much of it. But they people was spot on. Prices going up and lesson learned
