Log Max 7000C

The Log Max 7000C harvesting head is built on a tough frame and combines high drive power and high speed. This head performs very well in heavy and branchy trunks.

 

Log Max 7000C is a large head for the really heavy timber. The head combines high power and high speed, and performs very well in heavy and branchy trunks.

 

Variable displacement feed roller motors provide fast speed in smaller wood and automatically regulate to provide more power in tougher limbed trees. Well placed guards and heavy-duty covers protect internal components and hoses from damage.

 

High performance saw hydraulics provide full flow to the bottom saw for fast cutting in all timber sizes.

FEED ROLLERS

v-steel rollers  

V-Steel

By placing the stud bars in angled rows, Log Max has obtained a self cleaning feed roller with very high pulling force both in forward and reverse, without risk of spinning.

v-steel aggr. rollers  

V-Steel Aggressive

The V-steel Aggressive roller has studs that sink deeper in the tree trunk.

eucalyptus rollers  

Eucalyptus

Log Max Eucalyptus rollers have angled edges for debarking as eucalyptus demands complete debarking when felling.

OPTIONAL CHAINSAW

  • cut stump
