Chainsaw Weight Gallery
Chainsaw Bar Weight Gallery
I have been on the forestry forums since about 2010 or so. One of the most common arguments you see are about weight. And some of the most inaccurate statements are regarding weight. I found it sort of funny, because weight is not subjective. All you have to do is weigh it. So Neal Murphy and I got together since I had the web space and he did a business repairing and reselling all manner of saws. He weighed them, and I posted. Over the years, more folks came to me and added content, some I asked to borrow their images. Among the entire gallery there are a few variances, as there would be even if they all came straight off the factory floor with just one person measuring. Some are quite a bit different, but you have a scale right there to argue over VS just pulling numbers out of the air. The more images I have, the smaller the margin becomes.
Why this is important - folks often argue it isn't important. I'm not exactly sure why, but they do. It's important because it helps to maintain some sanity in the entire industry, as even officials have contacted me regarding the page as well, and not just chainsaw manufacturers. Some of the common web sites you can purchase these saws and attachments from use my site, free of charge, as a basis for their stated weights. But another important thing is chainsaws are combustion engines you have to hold in your hand. They are literally sold in a cc class which is a default weight class. You nearly always purchase a saw judging by how efficient it is to use for a one man operator. This means weight is a major issue for the engine size and output, with costs and power joining that metric. The only way one has even a basis of validating or denouncing any factory or posters claims is to know the weight/class of the device they are speaking of.
Another good example is the fact that the title on this thread says '70cc class'. Why bother dynoing a 70cc saw if it weighs 30lbs? No one is going to buy it. That's an extreme example, but it goes to show that all cc classes are also default weight classes - the weights matter. And when the factory knows other competitors actual real world weights - they take notice, and they make better saws for their displacements.
Why we/I weigh empty chassis only if we can help it. You buy a chassis only, and then add stuff to it. Your stuff is different than other's people's stuff - but your chassis is the same - it isn't subjective this way. We aren't comparing customs rigs here, we're comparing factory machines. The only way to do it is as they come from the factory without attachments. In this manner all chainsaws are born the same. They all have clutches, covers, handles, etc etc and only require a chain and a bar. So, from the factory, they are all basically the minimum mechanical requirement to be called a chainsaw. Sort of like a table saw in this aspect. Remove the blade from a table saw, and it's still a table saw. Remove the table or the motor, and it's just parts.
