Yes, I must eat a bit of “Crow”. This old man, in spite of many decades of experience was not fully prepared to understand all of the complexities of the Final Tier Four regulations and their effect on our machine’s performance. During testing, it looked like the Model 68C would perform as the older models did. It did not. Now we have a Model 68C machine working alongside an older machine and it comes up short on performance when screening heavy materials at near full capacity. Fortunately, when screening most materials the Model 68C performs as well as earlier models. What to do? After days and weeks of testing, searching for components and comparing what many vendors had to offer, we have decided to: 1.
Keep our Model 68C with its many refinements in our line of offerings
with no changes since it does perform well on many work
assignments. This also allows us to keep the pricing the same as
we have now for many years. 2. Offer a new Model 68C33 which will use a new engine with 33 Horsepower. Additionally, the hydraulic system and pump drive components will be upgraded to new higher levels of performance. 3. This will allow our manufacturing to retain the cost cutting efforts for most of the main machine components while only adding in the cost of the new engine and support items. The costs related to the EPA mandate unfortunately are quite substantial. Rational: A study of our customers shows us that the highest percentage of our customers use their machine to screen materials with a low specific gravity, like compost, mulch, bark and most top soil mixes. For these applications the Model 68C will serve quite well without paying the EPA mandated penalty for engines over 25 HP. For those who do need to screen heavier materials at as high a rate as possible, the extra cost can be easily absorbed by increased throughput when using larger screen opening sizes. For example, the earlier models 68B & C maxed out when screening rock at about 175 tons per hour feed rate using a 1 ¼” screen dish. That is all the engine could pull up the conveyors. With the new engine and hydraulic system changes we believe we can screen up to 225 tons per hour feed rate using a 2” or larger screen dish. Time and testing will prove our estimates, which will be soon as we have ordered many of the main components and are building the first EP weldments now. When life brings us Lemons (EPA) make Lemon Aid and smile, even if you are gritting your teeth. Please watch Brad’s Blogs for new news on our project. Happy screening Brad Schnittjer Blog # 83 5/1/2016
