Early on at the prototype stage, word spread fast. Farmer cooperators said they appreciated the RAZR’s simplicity, and its ability to place seed and fertilizer more efficiently in both till and no-till settings. Morris engineering, grounded by farmer input, made the difference.
The RAZR’s walking beam design allows for increased penetration force on the disc blade at higher speeds. “The farmer will be able to maintain higher seeding speeds even in tough conditions,” says Morris Assistant Director of Research, Clint Sheppard. “Unlike our competitors’ designs, the Morris disc opener transfers the force on the opener to where it is needed most – the disc blade.”
The single-shoot scraper on each disc is equipped with carbide inserts for long service intervals. The scraper can be adjusted upward to match blade wear. “The farmer gets maximum use out of the RAZR’s ground-engaging components,” says Sheppard. “With the single direction 5 degree blade angle, seed placement is not compromised with disc wear, unlike compound angled disc openers which can struggle with placement and plugging as the blade nears the end of its usable life.”
Scraper pressure is adjusted in the initial set-up of a machine, but the farmer adjusts down force and depth settings in the field. “The RAZR’s hydraulic down pressure can be adjusted from the tractor cab to change penetration and packing force on-the-go to match varying soil conditions,” Sheppard points out. “The RAZR’s depth settings are adjusted with a simple depth cam and pin at each opener similar to the C2 Contour. Openers can be adjusted quickly to change crop varieties or adapt to variable moisture conditions.” Sheppard says spoked depth gauge wheels allow farmers to start seeding earlier in tough, wet conditions. “They virtually eliminate plugging of the gauge wheel against the disc blade due to mud build-up. Scraper pressure can also be adjusted to keep the disc blades running clean in wet conditions.”
Low disturbance, single disc openers allow seeding at higher speeds than conventional hoe drills or independent hoe drills. In the field, this translates into more acres per hour seeded for a given drill size. For example, a 60-foot RAZR Disc Drill seeding at 6.5 mph will seed approximately the same number of acres per hour as an 86-foot C2 Contour seeding at 4.5 mph.
Sheppard adds, “Also, the RAZR has a 38% higher capacity bearing for all tapered bearings as compared to one of our competitors. Other major competitors use an angular contact bearing in their hubs with much lower capacity than ours as well.”
The RAZR’s advanced engineering is the direct result of Morris’ stated intention to listen to farmers. “We Hear You”.
