VuoluKalle is a belt-driven debarking and hewing device that replaces the bar on a chainsaw.

VuoluKalle is designed primarily for debarking logs, but can also be used for hewing loose timber with separate adzing blades. VuoluKalle is recommended for installation only on professional-grade chainsaws with an engine displacement of over 50 cc and no electronic engine management.

VuoluKalle is compatible with many Husqvarna and Stihl models – as well as brands based on these platforms – but exceptions exist. The compatibility list below is a general guide; in case of doubt, please contact us before ordering. VuoluKalle must not be installed on a saw with a plastic body or a quick-release bar attachment.

As a general rule for all saws, the oil pump or its drive component must be removed, along with the pump guard and spike bumpers if present.

On some Husqvarna models, you may need to replace the sprocket and/or clutch drum to fit the drive belt pulley, or add a separate spacer bushing. Stihl chainsaws are generally more straightforward to fit.

Among Husqvarna models, the 55 is an excellent match. Compatible Stihl models include the 029, 034, 036, 039, 046, 260 (not the quick-chain-tensioner version), 290, 310, 311, 360, 390, 391, 460, 650, and 660. The Echo 501 is also highly compatible.

For the following models, additional parts are required:

• Husqvarna 353 and 346 – drive belt pulley / clutch drum assembly
• Husqvarna 357 – spacer washer
• Husqvarna 546 – support bushing
• Jonsered 2512 and 2255 – drive belt pulley / clutch drum assembly

Examples of saws that VuoluKalle does not fit or is not recommended for:

• Husqvarna 242, 246, 440, 450, 545, 550, and 500i
• Stihl MS250S
