ROTTNE H11D

EGS596

EGS 596 is an allround harvester head designated to Rottne H11, H14 or H21. The head has three feed rollers, two located in supporting wheel arms that push the stem in towards the third feed roller. Using this principle the stem is held in a steady grip supported by the rollers instead of the limbing knives. This allows the knife pressure to be lowered, which reduces the friction and consequently ensures better utilization of the feed force. The upper and lower limbing knives and wheel arms can either jointly or individually be operated. Diameter measurement is performed via sensors in the lower knives and length measurement by a separate free-running measuring wheel.

LOGMAX 4000T

The LogMax 4000T hydraulics layout greatly improves power and feeding speed making this 833 kg* harvesting head the ultimate choice for thinning and lighter final cuts.

This thinning head comes equipped with the first-generation Log Max 218 and 318 True-Cut saw units with up to 58 cm of cut capacity.

All these features combined with Log Max patented knife control system, which minimizes feed friction, provides outstanding stem coverage and increased log quality.

LOGMAX 5000D

A versatile head with low weight which provides excellent properties for thinning and medium final cut. The head has a robust frame with internal components and hoses well embedded and protected against external damage. The design of the delimbing knifes provides good wrap and the patented knife control reduces the friction as the stem never is pressed up against the frame.
LogMax 5000D have high feed force but as an option there are larger wheel motors which increase the feed force to 25 kN but reduce the feed speed a little.
Equipment for multi-tree handling, color marking and stump treatment are available as option.

SP461 LF

A quick and versatile harvester head, designed for minimal friction and maximum production. The low weight in combination with its compact dimensions ensure smooth and easy positioning, regardless of the space and makes it an ideal harvester head for thinning.

The harvester head reaches its top capacity in stands with a b.h.d. of 10-25 cm, but also handles coarser stems in an efficient manner. It is in every sense – an immense small harvester head.

SP561 LF

Is a highly productive all-round harvester head, designed for minimal friction and maximum production. Designed for varying tasks and offering excellent characteristics for both light thinning as well as lighter final felling.

The compact dimensions in combination with perfect limbing down to 30 mm means that light thinning can be performed quickly and efficiently with the highest quality. For heavy felling, the smart LogHold and proportionally angled feed rollers create a harvester head with impressive stem holding and maximum production. SP561 LF is certainly compact, broad and versatile.

The harvester head reaches its top capacity with stems with a b.h.d. of 15 to 35 cm, but it also efficiently handles coarser stems thanks to the LF principle.
