Help setting Tp270k chipper blades please

[Jonny Burch]

Hi all. Hope you’re all well. Seems an age since I was last here! 

 

Just bought a tp270k for the Valtra and need to change the blades. Have the gauge thingy but not sure where to measure from?! 

 

Not fussed on chip size at the mo as everything I’m chipping on a job is just being blasted back into the woods. 

 

Any help would be much appreciated

There's a shear bar in there somewhere which effectively acts as one half of a scissors, the rotating blades being the other half. I leave a 1mm gap between blades and shear bar. Rotate the drum by hand after setting to ensure there's no bearing play and  then engage pto at low revs, if you hear any noise increase the gap.
