We have an elderly Kawasaki loader, with minimal hours, in good order. We also have about 20 HA (50 acres) of Kunzea (tick bush) that has been burnt in last year's fires, that a customer wants cleared up. It is very slow going with a 1.6 m (5ft+) rake on the SK135 Excavator, though it does a good job. The Komatsu D20 with a 2.4 m (8 ft) rake doesn't measure up to the job at all, insufficient weight and power to get the roots out. I have seen the 30 tonners with 30 foot rakes working up north- thinking that a 10 foot rake would be about the go on the loader. Has anyone got any experience with this? A D6 would be ideal, but not about to buy a machine for a one off job.
We have a 270-8 Komatsu. It has a 10’ rake. It’s a 15 ton machine. I’ve not really done any grubbing with it. Just mainly raking up debris that we’ve cleared with excavator and dozer. Hard to say what yours will handle without know what it takes to get it out of the ground. But I’d say an 8’ rake may be a possibility
