Rolly ll versus four-roller

[deastman]

How do they compare? The Rolly looks more heavy duty, does it work better in big hardwood,  more delimbing power than the four-roller? My four-roller has been really reliable but it struggles in bigger hardwood, I know it has a lot to do with the size of the carrier and mine is kinda small

 I bought quite a bit of hardwood off someone with a Timberpro / Rolly last yr and once it got into bigger limbs you where crudely sawing them off, much sweep you could see how it gouged. I'm seeing more and more of them for sale, I've talked with Woodland on some parts and they seem to stand behind the Rollys pretty good. 
 Have you seen the "Timberheads" made in WI ? I think at somepoint that's the route I'm going, the 24" dangle on a 153. They do also make 2x fixed heads which do 24-28".

Another option would be a skidmore head.

Well the four roller still has only two drive motors on it and I see there are conversion kits now to change them to two rollers. I can't comment on the Rolly as I have never saw one here.

One huge advantage with the 4 roller heads is you can drive them up a tree vs a two in a kink you'll be stuck even with a float.

Those Timberheads look like a nice head. I think the dangle heads follow the tree better but I'm not sure if they work better in hardwood.

Most of the newer fixed heads have a float function that will allow it to follow the tree vs drive them with your feet like the 2000 head.
