The new S-series brings grapple saws to three excavator size classes, and the R- and C-series will feature even larger tree shears. The LogRunner GS38 and MGS40 complete the lineup with saw products designed for crane use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This renewal is a response to the growing and diverse needs of contractors. Whether it is roadside clearing, problem tree removal, or mass harvesting of energy wood, our new products ensure that there is a solution optimized for the carrier and the application at hand.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" style=\"font-size:35px\">The new S-series: grapple saws for 4\u201325 tonne excavators<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:22px\">The S-series grapple saws are designed for felling, cross-cutting, and handling trees. In the S-series, a 360-degree hydraulic rotation system, three-finger jaws, and a felling support are included as standard equipment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The rotation system makes it easier to direct the grapple to the cutting point, and the felling support helps guide the tree during felling. Thanks to the electro-hydraulic control, all functions operate through a single double-acting hydraulic circuit. Chain lubrication is automatic and tensioning is manual.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Three models offer options for different sizes of excavators:<\/h3>\n\n\n\n<div

It is designed for 25\u201335 tonne excavators and has a cutting capacity of 400 mm.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The heavy-duty double-jaw structure is suited for heavy clearing work and energy wood harvesting. The grapple can be equipped according to the application: a 360-degree hydraulic rotation system, eBoost, and a collector are available as optional accessories.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The optionally available eBoost combines fast movement with cutting power that increases as needed. When cutting smaller trees, one cylinder is used. As resistance increases, the second cylinder engages automatically and without delay, with no noticeable interruption in the cutting motion.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The collector, in turn, holds previously cut small stems in the grapple while the next tree is being cut. This allows multiple stems to be collected before the bundle is lowered, which reduces unnecessary maneuvering..<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/jak.fi\/en\/products\/tree-shears-for-excavators\/jak-400r\/\">Read more about the JAK-400R model<\/a><\/div>\n<\/div>\n\n\n\n<div style=\"height:39px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-columns are-vertically-aligned-center is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"772\" height=\"1029\" src=\"https:\/\/jak.fi\/wp-content\/uploads\/2026\/09\/JAK-500C-08-edited-1.png\" alt=\"\" class=\"wp-image-20291\" srcset=\"https:\/\/jak.fi\/wp-content\/uploads\/2026\/09\/JAK-500C-08-edited-1.png 772w, https:\/\/jak.fi\/wp-content\/uploads\/2026\/09\/JAK-500C-08-edited-1-525x700.png 525w, https:\/\/jak.fi\/wp-content\/uploads\/2026\/09\/JAK-500C-08-edited-1-768x1024.png 768w\" sizes=\"auto, (max-width: 772px) 100vw, 772px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"wp-block-heading\" style=\"font-size:35px\">The JAK-500C brings more cutting capacity to the C-series<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:22px\">The new JAK-500C is a single-jaw tree shear designed for 25\u201335 tonne excavators, with a cutting capacity of up to 500 mm. It combines a large cutting capacity with a simple and cost-effective structure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The JAK-500C comes standard with three hydraulic cylinders and two eBoost units. When cutting smaller trees, one cylinder provides a fast movement. As resistance increases, a second, and if necessary, a third cylinder engage automatically and without delay. The operator does not need to change the operating mode.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The fast closing action helps to keep even small stems and branches firmly in the grip. The fast return movement shortens the work cycle. Thanks to the closed hydraulic circuit of the eBoost, the rapid motion function does not cause the oil to overheat.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A felling support is available as an optional accessory to assist with tree control during felling.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/jak.fi\/en\/products\/tree-shears-for-excavators\/j-jak-500c-tree-shear-for-25-35t-excavators\/\">Read more about the JAK-500C model<\/a><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\" style=\"font-size:35px\">LogRunner GS38: felling, cross-cutting and loading with a single attachment<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"800\" src=\"https:\/\/jak.fi\/wp-content\/uploads\/2026\/09\/Logrunner-GS38-08-1200x800.png\" alt=\"\" class=\"wp-image-19911\" srcset=\"https:\/\/jak.fi\/wp-content\/uploads\/2026\/09\/Logrunner-GS38-08-1200x800.png 1200w, https:\/\/jak.fi\/wp-content\/uploads\/2026\/09\/Logrunner-GS38-08-700x467.png 700w, https:\/\/jak.fi\/wp-content\/uploads\/2026\/09\/Logrunner-GS38-08-768x512.png 768w, https:\/\/jak.fi\/wp-content\/uploads\/2026\/09\/Logrunner-GS38-08-1536x1024.png 1536w, https:\/\/jak.fi\/wp-content\/uploads\/2026\/09\/Logrunner-GS38-08-800x533.png 800w, https:\/\/jak.fi\/wp-content\/uploads\/2026\/09\/Logrunner-GS38-08.png 1742w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:22px\">The LogRunner GS38 is a tilting grapple saw for tractor forestry cranes, forest machines, and truck-mounted cranes.
