Meet Sherwood Wheeler of AGCO, Inc.
MACS is fortunate to have a diverse group of members. People who work on many different vehicles and products that use mobile A/C and engine cooling system technology. Meet Sherwood Wheeler, a supervisor of dealer technical support at AGCO, Inc. in Hesston, KS.
Farming runs in Sherwood’s blood, he explains, “I grew up on the family farm in southeast North Carolina, so working on and around farm machinery came naturally. I attended North Carolina State University at Raleigh and continued on the family farm until I went to work for the local farm equipment dealer before joining AGCO’s technical services and support department.”
Sherwood has been a MACS member for 11 years and explains, “Being a MACS member allows me to stay aware of SAE standards and governmental regulations that affect mobile A/C, learn about new A/C equipment technology to assist the service technician and there is always the added benefit of networking with others that share a common interest in the mobile/C industry. In addition, MACS is focused on keeping its members informed in many different ways. They invite knowledgeable speakers from within the industry to present and conduct workshops at its annual conference and trade show. MACS keeps me informed through their newly launched mobile app, ACtion magazine, Service Reports and announcements about upcoming a/c training opportunities.”
AGCO Corporation is a global leader in the design, manufacture and distribution of agricultural solutions and brands such as Challenger®, Fendt®, GSI®, Massey Ferguson® and Valtra®. They manufacture agricultural solutions worldwide through a full line of tractors, combine harvesters, hay and forage equipment, seeding and tillage implements, grain storage and protein production systems and replacement parts.
We asked Sherwood what is the most important thing to be aware of with A/C systems in agricultural vehicles and he said, “Checking and servicing the A/C system on a regular basis is the most important thing, but unfortunately servicing is overlooked many times. Because of the harsh environment that ag vehicles work in, condensers and evaporators can become plugged with dirt and debris which directly affects system performance.”
Sometimes interesting situations arise from the field, Sherwood recalls one particularly troubled caller, “The most unusual a/c repairs are typically the small items that get overlooked or the person working on the system does not understand some basic principles. For example, I remember a service technician calling and complaining that he had just installed the second replacement A/C compressor, but still had the same problem of excessive high side head pressure. He explained that before he installed a third compressor, he decided to make a call for some advice. After discussing the causes for high, high side pressure and the importance of good air flow across the condenser, the light bulb seemed to come on in his head when he realized that there was nothing wrong with the original compressor when he ended the call by asking, who is going to pay for the two replacement compressors.”
Sherwood’s advice to his peers is, “Never stop learning.”
