Log Max 5000D

Log Max heads are designed for installation on various types of Carriers.For this reason, low weight is essential in our state-of-the-art design, given the fact that the CTL-method mostly uses wheeled pulling force to weight ratio.


Log Max 5000D is a versatile head for harvesting, ranging from thinning to medium final cut.


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. Log Max 5000D is an updated version of our previous big seller.


The Log Max 5000D can be equipped with an Accumulation Kit for multi-stemming and a Hultdins Supercut saw.

v-steel rollers  


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  


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


Accumulation kit


This allows the head to be used as a combination head - both as a conventional harvester as well as a multi-stemming head for thinning small wood or in late brush cuttings.


The Log Max Accumulation Kit can be run with Log Mate 500, (420), Motomit, CabsWin, Dasa 380, Ponsse Opti, Timbermatic and Komatsu Maxi.

New unique diameter measuring system Log Max harvester heads are now able to measure diameter with four points instead of two. Read more


Active Friction Control


The new generation floating top knife featuring Active Friction Control actively controls and adjusts the amount of friction between the log and the harvesting head's frame. There is no need to go out and change the settings by adjusting the unit, everything is now set automatically. Low friction is desired as it leads to lower fuel consumption and heat generation. There is the exception of when delimbing heavily branched trees with small diameter limbs a higher friction minimizes the risk of simply bending them flat.

The harvester's computer is the brain of the Active Friction Control and based on your settings, the Log Max head behaves optimally depending on tree species and diameter. For example, a thinning of pine and birch can behave quite differently based on tree species.
