GRAPE GRO WING • Clean any spills on painted surfaces im- mediately if using B20 or higher blends. • Replace fuel filter more often initially. • Check engine oil sump level daily prior to starting the equipment. • Use regular diesel fuel for standby gen- erators, occasional/seasonal applications and extended periods of storage or idle of the vehicle. • John Deere-approved fuel conditioners containing detergent/dispersant addi- tives are required when using blends of B20 or greater and are recommended when using lower biodiesel blends. John Deere also says that due to the solvent nature of biodiesel and the po- tential for "cleaning" of the vehicle fuel tank and lines, new fuel filters should be installed when biodiesel is introduced to older or used engines. For the first two changes, the fuel filter life will be half the standard. When using biodiesel blends greater than B20, which John Deere doesn't recommend, oil service intervals should be cut in half. Deere also says that biodiesel blends up to B20 should be used within 90 days of the date of biodiesel manufacture, since biodiesel is naturally biodegradable. Biodiesel blends from B21 to B100 should John Deere's warnings the risk of problems occurring in the engine in- creases as the level of biodiesel blend increas- es. The manufacturer doesn't recommend the use of raw pressed vegetable oils as fuel in die- sel engines pending studies of their impact. John Deere states that the following must J be considered when using biodiesel blends up to B20: • Expect a 2% reduction in power and a 3% reduction in fuel economy when using B20; • Cold weather causes flow degradation; • Stability and storage issues (moisture ab- sorption, oxidation, microbial growth); • Possible filter restriction and plugging (usually a problem when first switching to biodiesel on used engines); • Possible fuel leakage through seals and hoses; COMPLETE CRUSHPAD SYSTEMS LT™ & LT™ 2+2 (MOG Separators) Fruit Receiving Systems Bin Dumpers Sorting Tables Belt Conveyors Screw Conveyors Vibratory Conveyors Presses Destemmers & Peristaltic Pumps Destemmers, Mohno Pumps & Crush Rollers USED BY THE FINEST WINERIES TO ACHIEVE THE BEST RESULTS Call Now to Schedule Design Appointments!

Box 153 Wines & Vines JUne 2011 53 ohn Deere is clearly wary of biodiesel fuel in its equipment and warns of many possible downsides, adding that • Possible reduction of service life of engine components. It further warns that in addition to the factors above, the following must also be considered when using biodiesel blends above B20: • Expect up to a 12% reduction in power and an 18% reduction in fuel economy when using B100; • Possible coking and/or blocked injector nozzles, resulting in power loss and engine misfire if John Deere-approved fuel con- ditioners containing detergent/dispersant additives are not used; Vinters_GrapePress_Jun09.qxp 5/8/09 11:47 AM Page 1 • Possible crankcase oil dilution, requiring more frequent oil changes.
