Purpose Built Forwarder Thread (OSA, FMG/Bruunett, Entracon, Norcar/Logset etc)

TCD, You can have the engine out of a 578 in an hour if there is 2 of you.

I've got couple thousand tons to take out on reasonably straight forward site and then another few thousand from site, straightforward also but with a longer haul. Finally have another site that is bit steeper in places, got a few burns etc so will need to pick roads with but more care.

 

Can't decide whether to get osa 250, bruunett or new trailer/crane and run tractor trailer combo.

 

What payload are you guys getting on your 250's?

 

Thanks in advance

On the Osa 250, we are doing 16ft sawlogs and get a very easy 9 ton on and thats not full to the top of the bunks.The Bruunett takes 5 ton of 3m chip or 4 ton of 3m hardwood.You can see the Osa headboard has been widened by about nine inch each side and the bolsters dog legged.

Thanks Elf, it's the extra payload on the 250 that appeals. Just a bit wary of buying a machine with dodgy electrics or transmission on way out... Hence why thinking of tractor trailer combo, albeit manoeuvrability is compromised.

Looking good Elf

 

When it's loaded does it pull in high box or got to be in low?

[elfinwood saws]

We leave it in low box, it,s a half mile uphill drag to the stacking area. Never tried high box low is fast enough for me:thumbup:

The high low switch doesn't do anything in ours, its all on the speed controller rotary switch from standstill to pretty quick. I am struggling with a few problems at the moment. Fixed the oil pressure light and temp gauge, were bare wires touching so engine is good. now I have a problem where the engine keeps changing revs and I stopped it at lunch then it would turn over but not fire, bled it and sprayed wd40 in the intake and it went. So air leak or fuel starvation I think. When the engine is running well its fast but it bogs right down sometimes and ur crawling along. Sure its fuel, there is a breather on the front of the injector pump leaking so I need to sort that.

I'm currently moving hay bales onto a peat bog, about a 2 mile roundtrip so been running flat out all day to do 4 loads, plus the leaking rad isn't helping, runnng with bonnet open as it drops the temp by 10 degrees, gets very hot when suns out.

Also one of the batteries keeps corroding its clamp then snaps which then cuts the leccy so u stop, its the short positive between the two batteries, not sure how to prevent it!

The rebuilt crane is brilliant to use now apart from all this.

Reason for asking is I've got some jobs to extract over a field, some uphill and some down. As part of tractor/trailer query or 250 I was hoping could stick 250 in high for long hauls.. But think it unlikely unless downhill.

 

Log, your issues are what putting me off purpose built, asked my fmg mate about it also and he said tractor/trailer. Electrics on 250 mentioned again and also transmission weakness which could lead to £8k repair.

Simple O&F change has removed the oil pressure problem - seems too simple to be true but is running like a peach. Good job because I'm not spending any more money on it. Forwarder #2 better to put money into.
