|
| Carbody | Leveling 552 model features a bolted track frame to carbody design. This provides a standard gauge width, or allows adjustment to a wide gauge width to improve machine stability, and increase productivity on steep slope applications. |
|
| Heading | With up to 21,800 lbs (9400 kg) of bare pin lift capacity at 21.5' (6.6 m) on the 552 track feller buncher (with the standard linkage), the 500 series machines are dominant over competitors in their size classes. With market leading lift capacity, 28.8' (8.6 m) of reach, and tight stick tuck-in capabilities, these machines deliver high performance felling in all applications. The 552 track harvester delivers the same high performance with 12,500 lbs (5700 kg) of bare pin lift capacity and 37' ( |
|
| Attachments | From plantation thinning to select cut of large diameter wood, Cat felling attachments provide reliable productive felling solutions. These range in cut capacity from 22" to 24". Designed to allow maximum visibility of the cutting area, all saws utilize high pressure hydraulics for fast saw recovery and quick arm speed. This provides a positive impact on production and better tree control. |
|
