I purchased an HD36 in the fall of 2015 and am pleased with my transaction. I use mine for both personal use and custom cutting. I started with the basic mill (23Hp engine) and added the power up/down, hydraulic toe boards and log loaders 6 months later. In my opinion loading and positioning the logs manually (ramps and electric winch) was to slow at a customerís site. The power up/down option was purchased shortly after milling 35 logs into dimensional lumber for one customer.
If you are doing slabs the HD36 competes with the LT40 in that they both spec 28", the LT35 is somewhat less. Although it sounds like WM is offering wide versions now.
I should add I have a full time day job and most of my milling is done on weekends.
For me pros of the HD36.
Ease of use
Easy to Maintain
Trailers great behind my small pickup. (no need for electric brakes)
Add options as you go and can afford. My next option will be to extend to 16 feet.
Hydraulic log loader arms need to be removed prior to moving the mill. This is easy to do (couple pins) but they tend to be heavy after a day of milling.
It appears the HD36s shipping now have the Gas tank attached to the engine, mine has a detached tank.
In closing the HD36 is a very capable mill and works great for the type and volume of work I do. If I was given the option to turn back the clock and chose the Norwood over any other mill, I would still go with the Norwood.
That said in a perfect world where I could retire from my day job and the market permitted, I would want a new 2500 series pickup and a different shade of orange with a 55hp diesel engine.
