Low pressure controlled bottom knife

Low pressure controlled bottom knife

 

The bottom knife can now be controlled via a low pressure valve.
This way the bottom knife follows the stem better and pushes it upwards the stem track.

If you order a new Log Max 4000/5000 the kit RT033588 is required which includes a new valve 010284 for the bottom knife on the left hydraulic manifold. The hose from the rod side of the bottom knife cylinder must also be moved from “SM2” to “B2” on the left hydraulic manifold.
On Log Max 6000 a new hydraulic section 620571 is required. On Log Max 7000 a new hydraulic section 620564 is required.

The CabsWin control system is required in order to get low pressure controlled bottom knife on Log Max harvesting heads.

If the harvester head has a low pressure control system, the R2 reducer for the bottom knife needs to be set below 70 bar. Then the pressure on the R5 and R6 reducers for the delimbing knives may be set to the desired value. Finally, the desired pressure for the bottom knife may be set on the reducers R2 and R3.

If you order a new Log Max 6000 with low pressure control the part number is RT043378 and for Log Max 7000 the part number is RT033787.
