Ed Poore Posted June 4, 2020 Share Posted June 4, 2020 To be honest I think I'd rather have that run over my foot than a lorry of equivalent weight... It's actually pretty impressive how little pressure (for their size and weight) excavators exert on the ground. The bottom bank of what will hopefully become a pond was built using the 13 tonner I pictured before and Ben did a lovely job of smoothing it off. Drove the 6x6 and the Defender across it and both left an impression in the surface because the 13t machine didn't exert the same pressure as the 2t Defender.

Escape Posted June 4, 2020 Share Posted June 4, 2020 Yeah, the tracks are great for spreading the weight and reducing pressure and thus impressions. But tracks on bigger machines are steel, so I'd keep my feet far away from them! A HGV tyre at around 9bar/130psi is going to hurt as well... 1 Quote Link to comment Share on other sites More sharing options...

Ed Poore Posted June 5, 2020 Share Posted June 5, 2020 I remember as a kid noticing the rear tyre on the tractor was a little low so put some air in it, took it up to about 5psi. Then got told off by Dad because he normally ran them at 2psi Quote Link to comment Share on other sites More sharing options...
Escape Posted June 6, 2020 Share Posted June 6, 2020 @Blanco old tractors we're designed like that, not too heavy and with big tyres designed to run at (very) low pressure. Nowadays weight has increased more than tyre size so despite the huge rears on some modern tractors, they dig in the soft soil and tear it up a lot more than the old ones did.

Ed Poore Posted June 6, 2020 Share Posted June 6, 2020 Worth pointing out modern tractors are being asked to pull larger and larger implements to be more efficient. Was watching some videos of a farm in Canada recently where the tractor was being weighted up to close to 40t just so it had enough traction to pull the massive air drill. Mind you they were seeding fields that were multiples of 1000s of acres. Think they had about 5 of these tractors on the go simultaneously. The hilarious bit was they had some flooded spots they revisited at the end because the water had receded. One of them they gained another 100 acres because the water level had gone down. Different sense of scale out there. One moment on the road where a car goes past the pilot vehicle and doesn't pull over very quickly. Doesn't realise that the tractor physically can't stop off this little hill because it was fully loaded with seed at the time. Could slow down but not actually stop because despite having wet brakes they would have overheated. Quote Link to comment Share on other sites More sharing options...

Doesn't realise that the tractor physically can't stop off this little hill because it was fully loaded with seed at the time. Could slow down but not actually stop because despite having wet brakes they would have overheated. When I was driving mining trucks they had disc brakes but for normal use we had a retarder brake which I think worked via shutting off the exhaust which was operated via a lever on the steering column, if you used the foot brake heading underground it didn't take long for the front brakes to overheat and catch fire. Going down was normally about 30-45minutes at 40mph (top gear with engine on the limiter) which was an experience until you got used to it, in places there was less then a foot of clearance over head and on either side and lots of twists and turns, up could take 2 hours if loaded heavily, foot to the floor all the way!. One noticeable problem was you got used to driving using a lever on the steering column to brake (I didn't have road car at the time), jumping into a hilux was a bit of a change, none of the hilux's on the mine had indicator stalks left!. The trucks were Cat 768C's modified for underground work, from memory empty tariff weight with fuel and scrubber water was about 40tonnes and I regularly hit weight bridges over 100tonnes sometimes up to 120tonnes if it was high grade ore.

Ed Poore Posted June 6, 2020 Share Posted June 6, 2020 The ones I liked were, I think, a big mine in Russia. All electric dump trucks and they had to haul downhill from the mine. They'd generate so much electricity fully loaded coming down it cost them nothing to go back up when empty. 1 Quote Link to comment Share on other sites More sharing options...
rusty_wingnut Posted July 14, 2020 Author Share Posted July 14, 2020 well I've done a few jobs with this machine now, what with lockdown and all that. Anyway two things I've noticed: Â 1) it needs a cup holder 2) it needs a phone holder/charging point. Â I can see some mods coming! 1 Quote Link to comment Share on other sites More sharing options...
Ed Poore Posted July 14, 2020 Share Posted July 14, 2020 I thought I had two cup holders in the JCB. Turns out one of them is a broken air vent pointing at the back windscreen , drink got rather hot... No significant mods planned for the 2CX except building a frame to hold a set of pallet forks on the front quick hitch. Though it would be nice to sort: New battery Temperature gauge Why the heater only blows hot All the lights (at least check if it's simply blown bulbs) Give it a good service Quote Link to comment Share on other sites More sharing options...
