Name: John Deere 115 15' flail mower

2006-05-19 Mowing In the Biodiversity Study I flail mowed the rye in all replications of treatments B4 and B16, (B4 plots 104, 220, 307, and 404) (B16 plots 101, 210, 308 and 416). Flail mowing was completed with JD 7420(a) tractor and JD 115 flail shredder. Treatment B4 has a three year crop rotation of corn-soybeans-wheat with the use of cover crops. Treatment B4 plots where planted to corn in 2005 and had rye planted after corn harvest in the fall of 2005. Treatment B16 is annually planted to soybeans, no crop rotation, with the use of cover crops. Treatment B16 plots where planted to soybeans in 2005 and had c. rye planted after soybean harvest in the fall of 2005. The decision to flail mow the rye was based on the height and stage of development of the rye. The majority of the rye was between 18-31 inches tall and had developed the seed head. At the time of flail mowing the rye had not pollinated and therefore did not have viable seeds. I was concerned that if we had just chisel plowed some of the rye could have still matured enough to produce viable seeds. We did not want are cover crop of rye to become a weed problem in the annual crops.

We had such good growth of the red clover that we decided to mow the red clover before chiseling plowing the T4 plots. Without flail mowing we did not think the red clover would had been incorporated into the soil. Flail mowing prevented large clumps of clover on top/in the soil, preventing the clumps of clover allows for a better seedbed preparation.

2011-05-31 Mowing Flail mowed the LTER Main Site Biodiversity Study, all non-wheat treatments that still had cover crops except the fall fallow, which was not mowed. The following treatments were flail mowed: B4 (plots 104, 220, 307 and 404), B5 (plots 114, 217, 312, and 405), B7 (plots 105, 219, 305, and 417), B8 (plots 118, 214, 310, 408), B14 (plots 115, 204, 304, and 414), B15 (plots 112, 213, 301, and 415), and B16 (plots 101, 210, 308, and 416).

2011-12-20 Mowing Flail mowed the LTER Main Site Biodiversity Study treatment B2 (spring fallow) (plots 102, 206, 316, 402). The plots were mowed to approximately 6-8” height across the entire field. Mowed with the John Deere 115 flail mower on the John Deere 7420a tractor.

2012-05-14 Mowing Flail mowed c. rye in the LTER main site treatments T3 and T4 plots, all reps: T3 (reps: 6, 3, 1, 2, 4, and 5), T4 (reps: 6, 1, 2, 3, 5, and 4). Flail mowed with JD 7420b tractor and JD 115 flail mower. We had such good growth of the c. rye that we decided to mow the c. rye before chiseling plowing the T3 and T4 plots. Without flail mowing we did not think the c. rye would had been incorporated into the soil. Flail mowing prevented large clumps of rye on top/in the soil, preventing the clumps of rye allows for a better seedbed preparation. The rye started to put a seed head on so we wanted to prevent any of the rye from producing seed before chisel plowing.

2012-05-15 Mowing Justin Mezo flail mowed cover crops, red clover and/or c. rye, in the LTER Biodiversity treatments B3 (111, 203, 306, 403), B4 (104, 220, 307, 404), B6 (107, 207, 317, 406), B7 (105, 219, 305, 407), B15 (112, 213, 301, 415), and B16 (101, 210, 308, 416). Flail mowed all corn and soybeans treatments that had cover crops growing in them. Flail mowed with JD 7420b tractor and JD 115 flail mower. Flail mowed with JD 7420b tractor and JD 115 flail mower. We had such good growth of the red clover and c. rye that we decided to mow the cover crops before chiseling plowing the treatments. Without flail mowing we did not think the cover crops would have been incorporated into the soil which would have caused large clumps of biomass creating a poor seedbed. Flail mowing prevents large clumps of red clover and rye on top/in the soil. Preventing the clumps of biomass (i.e. red clover and rye clumps) allows for a better seedbed preparation and better seed to soil contact.

2012-11-13 Mowing Flail mowed LTER Main Site Biodiversity Study, corn treatments: B3 (111, 203, 306, 403), B6 (107, 207, 317, 406), B9 (119, 205, 314, 409), B12 (109, 202, 313, 412), B15 (112, 213, 301, 415), and B18 (108, 208, 311, 418). Using JD 7420 A and JD 15' 115 flail mower corn stubble was mowed to assist in the decomposition of stalks.

2012-11-13 Mowing Flail mowed LTER Main Site Biodiversity Study, soybean treatments: B4 (104, 220, 307, 404), B7 (105, 219, 305, 407), B10 (117, 209, 320, 410), B13 (113, 212, 319, 413), B16 (101, 210, 308, 416), and B19 (103, 218, 315, 419). Unable to harvest remaining soybeans after harvesting with Kincaid it was decided to flail mow soybean plots. This would shorten any remaining biomass and to allow for easier and more consistent tillage. Cutting height of mower was set to around 5 to 10 inches. Used JD 7420a and JD 15' 115 flail mower.

2012-11-13 Mowing Flail mowed LTER Main Site Biodiversity Study, treatment B1, B2. Fall and spring fallow plots were mowed with JD 7420 A and JD 15' 115 flail mower.

Soybeans were mowed approximately 4 - 8 inches across the plots with the John Deere 115 flail mower on the John Deere 7420a tractor

2012-11-13 Mowing Flail mowed the east 15' of the no-till Interaction plots. No herbicide is applied to the east 15' of the no-till plots allowing weeds to become very thick. Not wanting to run the combine through weeds we decided to mow strips with the John Deere 115 flail mower on the John Deere 7420a tractor.

2012-11-13 Mowing Flail mowed the LTER Main Site treatment T8's all replications (rep 1, rep2, rep3, and rep4). Mowed with the John Deere 115 flail mower on the John Deere 7420a tractor.

2012-11-14 Mowing Flail mow bait crop in GLBRC where corn was planted. Mowed with JD 15' 115 flail mower pulled by JD 7420a tractor to help decomposition of corn stalks.

2012-09-05 Mechanical Weed Control Flail mowed LTER Main Site Biodiversity study wheat plots; treatments B5:(114, 217, 312, 405), B8:(118, 214, 310, 408), B11:(110, 216, 309, 411), B14:(115, 204, 304, 414), B17:(116, 211, 302, 417), B20:(120, 215, 318, 420). Severe drought through the summer months inhibited establishment of clover cover crops in treatments B5:(114, 217, 312, 405), B8:(118, 214, 310, 408), B17:(116, 211, 302, 417). Weeds had established and were suppressing the growth of clover crop. Goal of flail mowing plots was to control weeds such as ragweed which allowed for late season clover growth. Wheat plots that did not have clover cover crop were mowed strictly for weed control. This was done using JD 7420a tractor and JD 115 flail mower.

2012-10-02 Mowing Flail mowed LTER Main Site treatments 1 & 2 micro plots, all replications. No herbicide is applied to these micro plots leaving weeds to thick to run through combine. Goal was to mow weeds down before main plot was harvested so the combine did not have to harvest the weeds. This was done with JD 7420a and JD 115 flail mower.

2012-10-02 Mowing Flail mowed GLBRC bait crop corn residue as well plots in rep 6 and near the brown house. Corn stalks were mowed to assist in decomposition of residue. Plots in rep 6 and near the brown house were mowed due to the crops lack of growth caused from severe drought through summer months. This was done using JD 7420a and JD 115 flail mower.

2008-08-01 Mowing Flail mowed LTER T6 plots, all reps.
