ROLLER FEED HARVESTER HEADS Strong, modular frame structure The frame structure consists of modules which are machined as one piece after the welding assembly. The excellent dimensional accuracy of the structure ensures a long bearing life. The frame has been made out of the best highstrength steels available with regard to durability and weldability. The wide, cradle-like frame offers a robust structure with respect to its weight.
Excellent serviceability Wider frame structure provides plenty of well-protected space for the valve system and hosing, and enables ease of maintenance. The chain oil tank is easy to remove for oil pump maintenance. Removal provides plenty of room for other maintenance work as well.
Well protected hydraulic hoses and cylinders The cylinders are repositioned and hoses rerouted for maximum protection. Easy hose replacement from inside the protective cover.

Accurate diameter measurement The diameter of the tree is measured at the front delimbing knives so that changes in the hardness of the wood do not affect the measurement accuracy. The sensor, located alongside the delimbing knife cylinder, is now significantly more robust and well protected. The linear analogue sensor is accurate and provides a stable signal in all conditions. Alternatively, the head can be equipped with pulse encoders on both delimbing knives.
Reliable feed Rerouting and redesigned protection improve the durability of the hoses and connectors significantly. Also the optional in-motor length encoders are well protected. The feed rollers and roller arms are designed to minimize the stress on the feeder motor bearings. This ensures that the motors have a long service life.
Strong tilt The tilt arm with a straightforward side profile without unnecessary corners is a very strong construction relative to its weight. The link is in line with the tilt’s pivot point and the feed motors, which minimizes the stress on the structure and makes the head well balanced during both harvesting and processing. The corners at the backside of the tilt are rounded to protect the head hoses from wear. The wide tilt angle enables efficient work also on steep slopes. There are several options available for tilt control, depending on the user’s needs.
Heavy-duty axles The robust roller arm and delimbing knife axles are mounted with sealed heavy-duty bushings. Bearings are also used for axial movement. All axles and pins are hardened. The axles are fixed with heavy-duty axle nuts and locking screws.
Reliable length measurement The new hydCON+ length measuring system is now more robust in structure. The combination of a double-acting cylinder and coil spring ensures good and constant grip of the measuring wheel, and keeps the impacts on the structure well damped. The length measuring wheel is automatically retracted for the time the tree is gripped and then pressed out after the felling cut. The measuring wheel features heavy-duty bearings. The contactless pulse encoder is waterproof. The head frame design keeps the measuring wheel clean during delimbing, preventing loose bark from compromising the accuracy of the length measurement.
Strong delimbing knives In RH-III heads with a modular frame, switching from a 3-knife to a 4-knife design or vice versa is also possible as a retrofit. The dimensions of the strong steel-cast front delimbing knives are very accurate and their wear-resistance is excellent. The optimally designed knives that stay sharp for a long time ensure excellent delimbing results and accuracy of measurement.
The idle roller makes the wood move easily The idle roller is bigger than before and equipped with stronger bearings. Thanks to the redesigned frame, the tree is always steered to the head’s center line, improving the feed power and measurement accuracy. The frame design also ensures the smooth feed of crooked trees. In models 28RH-III and 30RH-III, the upper roller can also be driven.
Efficient KESLA HD30 saw The new KESLA HD30 saw is equipped with a 30 cc motor with plenty of torque. The structure of the patented automated chain tensioner is simple and reliable as well as very easy to use. The bearing of the swivel arm based on precision-machined, hardened sliding surfaces lubricated with saw chain oil are maintenance-free and extremely reliable. The electrically controlled KESLA proLUBE lubricating pump allows precise saw chain lubrication dosage according to the demand.

SUPERIOR ADVANTAGES OF PROGRESSIVE ROLLER GEOMETRY Kesla’s unique progressive roller geometry combines the strengths of the side-pressing 2WD heads (A) and the traditional triangular geometry of 3WD/4WD heads (B) without any compromises.
A
B
C
When the rollers carry heavy large timber, the mass of the stem enhances the grip of the rollers. The wood
mass stresses the delimbing knives less, and the friction between the head and the wood is minimal.
As the diameter decreases, the rollers gradually turn to grip the stem from the side and between each
other. Small stems are not squeezed against the frame of the head; instead, they are moved lightly between the feed rollers, ensuring that the friction between the head and the stem remains low and maximum grip is achieved even on the branched tree tops.
The floating stabilizer bar between the feed rollers allows the rollers to follow the shape of the stem more
freely while still keeping a tight grip. Even crooked trees are fed smoothly and easily.
In 3WD/4WD systems, the speed differences between several feed rollers, which are often of different
sizes, always cause pressure peaks and power losses. In Kesla’s 2WD system, the pressure compensation between the feed motors prevents slipping while still allowing for speed differences between the rollers due to the crookedness and elliptical shape of the stems without causing harmful pressure spikes.
Multi-stem processing makes collecting the stems and feeding several stems in a bundle efficient.
The 2-motor hydraulic system excels in the handling of oil flow. The pressure losses in the system are as
much as 20% lower, which means improved net power and fuel economy.
The simple structure of 2WD heads also means easier maintenance.
The weight savings range from 100 to 200 kg compared to the 3WD or 4WD heads, depending on the size
of the head. The excellent power-to-weight ratio of the KESLA heads increases the productivity of harvesting and improves energy efficiency.
Kesla’s 2WD system makes it possible to optimize the size of feed motors thanks to a very wide selection.
As a result, the KESLA harvester heads can be adapted to a wide variety of base machines and operating conditions.
STROKE FEED HARVESTER HEADS Kesla is one of the pioneers of stroke harvester technology and the uncontested technology leader in the world. The KESLA SH-II stroke harvesters made for heavy professional use are largely comparable to Kesla’s roller feed heads with regard to their technology, components, quality and features. Thanks to their massive delimbing power, the KESLA SH-II stroke harvesters are an excellent choice especially when you need to process large and branched trees with modestly powered base machines.
Strong tilt The KESLA SH-II harvester heads have a strong tilt with an exceptionally large tilting angle, which enables efficient processing even on steep slopes. The structure of the wide tilt with its straightforward side profile is extremely durable compared to its weight. There is a variety of options for tilt control available depending on the user’s needs.
Light and durable structure The casing-like structure of the stroke harvester head’s frame is extremely durable compared to its weight.
Excellent serviceability The simple and spacious structure of the stroke harvester makes it very easy to maintain.
Powerful and durable saw The KESLA stroke harvester heads feature the same simple and reliable saw unit as the RH-II heads. The JPS R5500 saw unit is also available as an option.
Delimbing power A hydraulic cylinder can produce staggering delimbing power even with very modest hydraulic power from the base machine. The maximum feeding speed is lower than roller feed heads, but the massive delimbing power makes it possible to delimb difficult branches in one go without backing up, which results in the efficient processing of stems with many branches even with a small base machine.
Precise measurement and control The KESLA SH-II heads use the same extremely accurate measurement sensors and solutions as the roller feed RH heads. The KESLA proLOG measurement and control system offers the SH-II series the exact same features and functions that meet the latest market requirements as in the roller feed heads.
Unique proSTROKE partial stroke function The partial stroke function means that the total length of the head can be minimized during feeding, which makes feeding of curved trees easier.

EQUIPMENT HydCON and HydCON+
Butt-log sensor
In the HydCON system, the coil spring of the traditional measuring wheel is replaced by a double-acting hydraulic cylinder that enables automatic retraction of the measuring wheel during work stages other than delimbing. Retracting the measuring wheel protects it from hits while gripping the tree and makes it easier to place the head on the tree. The HydCON+ system (standard with KESLA RH-III heads) has both a spring and a double-acting hydraulic cylinder in parallel, which provides more accurate measurement than ever in all conditions. Several different profile options for the measuring wheel are available for different conditions.
The optical butt-log sensor recognises the butt of the tree, which makes it easy to return to the butt of the stem and set the length measurement to zero without sawing.
ProAX
Hose connection block
The KESLA proAX cutting system offers a phenomenal combination of the possibilities of saw and guillotine cutting in the same head. In felling small-diameter trees, it makes cutting faster and minimises damage to saw chains and bars. In addition to lower chain and bar costs, it also creates savings in fuel costs because cutting with a cylinder takes much less energy than using the saw motor.
moves the connection point of the hydraulic hoses coming from the boom from the inside of the head into a connection block below the rotator, making the hose bundle coming to the head shorter and more compact.
Multi-stem processing An accumulation grapple attached to the tilt makes collecting and processing the bundle easier in multi-stem processing. The rotator has been embedded into the grapple equipment so that the grapple does not increase the total height of the tilt.
