  1. We had a job about 5 years ago on a A530 tracked where this happened. It was down a bank by a stream, blade went through the hydraulic tank. Recovery tools included a 4" fence stake, wheelbarrow, bucket of tools, oil sucker and some straps. We walked to the machine from the van, removed the flywheel on the bank lifting it out on our shoulders using the stake and straps, we then sucked the hydraulic oil down past the damaged tank, drove the machine out of its location at low revs and tracked it back to the van where the trailer was with the flywheel in the wheelbarrow. Once in the workshop we plated / welded up the hydraulic tank, replaced the damaged bearings, refitted the flywheel with new blades and the machine went on its way. Quite a fun job in some respects for us... Not so much for the paying customer.
  2. We copper slip CS100, TW 125 & TW150 blade bolts. TW blades and GreenMech blades sit in a pocket / against a ledge so the load going through the retaining bolt is fairly low in reality.
  3. They are M16 bolts, 10.9 grade (I think) Its the same setup as Jensen, the Forst blades look identical to a Jensen. Whether they actually fit I have not tried. We sharpen quite a few Jensen blades, never seen one crack though. Again the Jensen torque is 310nm. In the past I have torqued them to 250nm and even then it feels damn tight.
  4. Just had a set of Forst ST6 blades in for sharpening...
  5. Flywheel bearings on the way out. Rumbling at idle is often the first sign. You want to take the belts off and get a proper length lever bar down the side of the flywheel checking for any play.
  6. Fair enough. The new Evo 165 models are as follows. EFI Petrol, 750kg, single piece heavy duty chassis, metal bonnet, 70kg flywheel, cable throttle. Kubota 25.5hp diesel, 950kg (approx) weight, heavy duty chassis with adjustable height drawbar, folding chute, 101kg flywheel, metal bonnet, electric throttle. Both have led lights, locking hitch, 3 year parts and labour warranty (unlimited hours), no stress, letterbox style horizontal feed rollers, "floating" stop bar. The feed roller box location has been moved from the conventional 6 o'clock around to 9 o'clock. This allows more time for the material to exit on its first counter clockwise pass and less recycling of chip around the drum. Quicker processing and quicker discharge resulting in ultimately quicker feeding of fresh material. 70kg flywheel on the petrol may sound on the face of it a bit light, but the Arb 130 /150 models weigh in around 50kg. The Arborist 130 (23hp Honda), Arborist 150p (37hp EFI) and Arborist 150 (25hp Kubota diesel) are all 750kg and all still available. I have a 2019 Arborist 150 with 250 hours coming in next month which boosts the old 34hp Kubota turbo diesel engine. It still has 18 months manufactures warranty and I can stick it through on GreenMech finance if required..
  7. Towing with auto is a dream for sure. I had a D3 Commercial a few years ago and towing was effortless. I know i'm towing in the Defender Puma these days, it's like a work out.... But I also find it fun. It can be dangerous towing in a powerful smooth auto, the speeds you can be doing with 3T on the back without realising! It seems a bit backwards for them to bang on about being this cheap rugged 4x4, with beam axles, the answer to the true Defender owner blah blah blah yet only offer auto. For example a sheep farmer plodding around his livestock will want a 5/6 speed manual. He'll also stick with a jap pickup because of this? The Ineos will make a good tow vehicle. But then so does the Disco and new Defender... I have my eye on the 6 cylinder Defender 90 Commercial. That'll be a great truck for hauling chippers about.
  8. The Evo 165 petrol is now a 750kg machine... Chris Murphy, are you restricted to 750kg?
  9. Exactly, price is everything on this to make it successful. Why add a 8 speed complicated expensive box if your target market is apparently farmers / workers? Isn't the idea of it that it can be repaired in the out back and beyond with minimal specific tools?
  10. We can do you a good price on a new one.
  11. Being a GreenMech dealer, if this was a GreenMech and you had used genuine blades, bolts and a torque wrench (even using an uncalibrated torque wrench is a massive step to show you’re carrying the job out correctly) I would be opening a warranty job card and shovelling it through as warranty unless evidence was found during the repair of improper fitment or use. I don’t mean this reply as a “you should of bought a GreenMech” Professionally detail to the supplier what you’ve done prior to the fail and the fail itself. If it’s falling on death ears look to get an independent engineers report?
  12. The M16 bolts are £2 something, nuts are 60p and nordlock washers about £1. Genuine new blades are £39.50. As the blade sits in its own pocket in a GM the bolt doesn’t really take any of the load. If it’s a machine we look after half the time we just replace the washers & locknuts so the nylock is fresh. If it’s a used machine / Part ex that we have never seen before we’ll always stick new bolts on.
  13. Blade change including swapping for sharpening? I prefer a blade that seats itself rather than the full load going through the bolt.
  14. Is it a Jensen or Forst? 300+nm does always seem very tight for a M16 bolt.
  15. Lubricated threads and dry threads torqued to the same setting will give a different tightness. But not to the effect of snapping blades. If that’s correct they should 100% have a decal saying only torque dry, that commonly chosen method of lubricating threads shouldn’t carry a risk of killing someone / damaging the machine.
