Rodney Guest has been running Gleaner for 35 years. He picked Gleaner because of it's simplicity, ease of operation, ease of sample and the great reliability of the machine and maintenance. Grain loss in the Gleaner is second to none. "I always get complemented on the grain when I deliver it". The seven cylinder sisu engine which is under here somewhere is a great engine – I truly love it. I purchased my S78 from Serafin AgPro. I highly recommend Serafin AgPro. They have been just great.
