I'd like to see Woodmizer offer thr Stage 4, Tier 4 Volvo Penta engine as a power option. That engine the best Tier 4 engine available right now in my opinion. It is so clean and efficient it doesn't even need a regen system.

I have run a couple of them in Volvo and JCB machines. They are impressive all around and economical.

I run .055 x 1.5 Turbos for everything. Also, I can’t tell a dimes worth of difference between the WM Double Hards or the WM Silvertips, which I guess are just single hards.

Wait, there is a difference. The Silvertips very rarely fatigue crack and they are $23 each instead of $42 each.

The LT70 Super has engine driven hydraulics, and the speed of the hydraulics can be controlled, to a point. If the engine is in idle, the hydros run at about the same speed as a Super. However, if throttled up, the hydros run many times faster.

My Cook's AC36 has a 57 hp Perkins engine and I can find no mention of any "regen" in the manual and have not seen or noticed any difference in its' operation in 290 hours. I reserve the right to be wrong. I thought I was wrong once, but was mistaken.

Correction---67 hp Perkins. I feel better now that I broke the ice!

I get blades 60 at a time, 15% off with free shipping. Those not familiar this is standard Woodmizer quantity pricing.
The Doublehard 195 055 1.5 blades come out to $30.68 each.
Silvertip and Kasco equivalents are about $27 each.

That’s a lot cheaper than I’m getting the Double Hards, although I haven’t bought any in a awhile.

I’d have to say, and this is what I’m thinking right now, so my opinion can change tomorrow, if I could get Double Hards and Silvertips at the same price, I’d still probably run Silvertips. The money I lose on DH fatigue breaks tearing up my band wheel belts even more offsets the costs and makes the Silvertips more attractive.

I really think the double hardening process makes them much more fatigue prone after several sharpenings.

This is still an experiment in progress, but so far so good.

I will probably try some silvertips on my next blade purchase.

Mr. YH
I'm running the 1.25 x .042 t7 silver tips hard in frozen red pine and ash that's been on the ground 2 years.
I won't buy another Double hard.
The silver tips cut great for me. I buy them for $16 .00 for a lt 40 wide.
I don't use them for anything over 24" wide.
I go to a 1.5 x .050 x 8 °
Or frost notch 1.25 x .50 x 7.5°
The .050 most alway break after one sharpening.
3 x on the 8°

Bruno, that’s good information. Thank you.
