Important Dues Information

A reminder that your dues are now due and payable. This will cover your membership for the period from April 1, 2019 to April 1, 2020. Due to the increase in insurance costs (and coverage), the National now requires a payment from our club of $17 for each principal and auxiliary member. The Board of Directors has decided to have club treasury absorb these increased costs for 2019. But it will be necessary to raise the dues by $5 per principal and auxiliary member starting in 2020. This dues increase will be discussed at the upcoming annual meeting and the membership will vote on it at that time. This notice serves as the required notification announcing that agenda item and vote. For more information on the insurance changes, please see Wilbur’s President Message on Page 1 of this issue.
The new dues schedule for 2020 will be as follows. Principal members are $30, auxiliary members are $22, and dual members are $15. Spouses and dependent children from 12 to 18 years old of principal members are considered auxiliary members. Those with membership in a different EDGE & TA branch, may join Branch 158 as a dual member with full membership privileges for $15.00 per year along with proof of membership (i.e., photocopy of card) in the other branch.
Please help Sue with our records by renewing soon. Many members find it most convenient to renew at the annual meeting. You may also use the renewal form in this issue if you want to renew by mail. More details are on the last page of this newsletter. If you fail to renew, this will be your last newsletter.

President's Message

I hope all of you had a wonderful Holiday and that Santa was good to you and brought you that tractor or engine you have been wanting. I have been doing a few repairs on engines but have not started any major project. My wife and I observed the Winters tractor light parade in December. Sue participated with her tractor all decorated in lights. The parade was very impressive.

Branch 158 annual meeting will be held on Feb. 16 (see article in this newsletter). Please call me if you would want to run for office or you can put your name on the list at the meeting. This is your club. We want people who have ideas on how to make the club better. Participation in events is needed to help the club grow.

The National has raised insurance rates effective now, but the Board voted to put off raising our club dues this year. They will need to be raised in 2020. The insurance coverage is also improving. I will try to cover some of the insurance questions that you may have. The club insurance is liability insurance. It protects spectators and their property at the show. It does not cover going to or from the event. Your personal or vehicle insurance should cover this although you may want to check with your policy holder. It does not cover you as a member getting hurt. It does not cover damage to your tractor, equipment, vehicle or trailer. The new insurance that takes effect in April changes this somewhat in that the insurance will now cover an incident involving another participant of a community parade and of a member to member incident.

The insurance covers sanctioned club events. It also covers your liability at events such as parades, fairs, school events or businesses that you may take an exhibit to as long as the event is discussed at a board of directors meeting and is mentioned in the minutes. It could also be approved by the club president or safety director if they are contacted before the event and have given their OK. I would expect this request would be in writing stating all pertinent information so that proper judgment could be made.
For more detailed information you may go to the national EDGETA website ( and look at the Insurance FAQ’s question and answer section. It can answer most of your questions. Questions on the new improved insurance policy have not been posted yet but should be on the web site by sometime in April.

Safety requirements at shows and tractor drives are not optional. You can’t use the ones you like or agree with and ignore the rest. The safety requirements were put together by members of the organization with experience in operating tractors, engines and other equipment. These requirements are not difficult to follow. They were put into place to protect the membership. If you are not following them, you could be putting you or other members of the organization at risk. A club or organization is a group of people with the same goal or vision. They look out for each other. Please keep that in mind as you are showing off your antique farm machinery.

Safety is the responsibility of each and every member. Our hobby can be safe for everyone but it requires continually thinking safety. Let’s make 2019 both an enjoyable one and a safe one. Our board has planned gas ups, tractor drives and events for this year. You may also participate in events that other Branches of EDGETA hold. All you need is your EDGETA card with a current sticker on it The year’s sticker is good until April 2020. I hope to see you at many EDGETA events this year. Let’s make this year a very enjoyable one.

Show Reports

Fall Tractor Ride
By Dave Honer

The fall tractor drive from Plainfield to Lake Solano and back went off very well. The weather was near perfect but there were a few minor hiccups. First, the starting place had to be changed due to a conflict scheduling with West Plainfield parking lot.  Thanks to Wilbur for offering his nearby place to use as a starting point.
Second, soon after getting on the road we quickly realized we were sharing the road with a big bike event.  This turned out to not be a problem, I think they like it as they passed us waving and smiling.
Third, all tractors that started, finished.  Only one guest tractor had a minor problem.  Thanks to Wilbur and tow straps we were able to get the tractor to the finish line. 
We did about 33 miles covering different types of farming from open large fields, to vineyards and orchards, also passed by vintage tractors and equipment along the way.
Lunch in Winters is always a hit, as many of the excellent restaurants  are within a very short walk.  Thank you to everyone and especially the guests from other clubs who participated. As this was my first event as  director, I want to thank everyone for their input and help.
P.S.  I’m  already looking forward to the Colusa ride in May—make sure to book your room now.

Fun Day/Open Barn and Shop

Pat and Martha Garrison hosted the Fun Day event this year on June 9, 2018. They had help from nephew Richard Garrison and brother, Howard, and sister in law, Jeanne.

Pat has a very nice collection of hit and miss engines and he and Richard had many of them running. I think Pat himself was surprised at how many engines he had when they were all out on display, over thirty engines in all. The star had to be his 8 hp Samson, freshly painted bright red and on its own cart with a black cooling tank. The hamburger and hot dog potluck lunch which followed was great. Thanks to Martha and Jeanne for all their work in setting it up and to Howard for cooking the burgers. Also thanks to everyone who brought side dishes and desserts to complete the meal.

Colusa Tractor Ride

The weather was perfect as 10 intrepid tractor drivers set out from Yolo to Colusa, some 50 miles north on May 5, 2018. We had a couple out of towners, Leland Miller and Walter Curtis, from Branch 106 in Winnemucca, driving with us this year. It is always fun to share the ride with members of other clubs.

The ride was eventful, though, because the tractor Ed Morris was driving almost lost its left rear wheel. Luckily John Boehm, who supplied the tractor, was following Ed, noticed the wheel was about to wobble off, and sped up to stop Ed. The tractor was taken back to the barn and the ride continued. We arrived at the Riverside Inn and set up for our happy hour under the hotel awning. After some snacking and socializing, we walked over to Rocco’s Grill for dinner. Irwin Graves and Maria Corona drove up and joined us for dinner.

Sunday morning, bright and early, the drivers left for the return trip, this time along the beautiful Sacramento River. There was another mechanical issue. This time, the front spindle on Dudley Newton’s tractor broke off. No one was hurt and we are thankful for that. He was even able to drive his tractor onto his trailer despite the missing front wheel and hub. Everyone made it back to Yolo and another endurance ride is history.

Annual Meeting

The Annual meeting of Branch 158 was held on February 10, 2018 at the the Raley’s meeting room in Woodland. After the pledge of allegiance and introductions of members present, the treasurer’s report was given by Sue Westwood. The event calendar for the coming year was discussed and several events are being dropped from the calendar, in part due to poor participation by the membership. This poor participation was also a subject of discussion and John Boehm suggested that if participation does not improve, that disbanding of the club should be considered as an option. Full details on this year’s events are given elsewhere in this issue of the newsletter. Other events discussed included some of the lighted Christmas parades in the area.
Old & New Business discussed: T-shirts, Porta-potty, Safety.
The meeting ended with the election of officers. The following officers were elected: Wilbur Reil, President; Kathy Boehm, Vice President; Sue Westwood, Secretary/Treasurer; John Boehm, Editor; Ed Morris, Safety Director, and Pat Garrison and Dave Honer, Board Members.





Plow Day 2015

Branch 158 Fall Plow Day 2015

Our Ninth Annual Plow Day was successfully held on November 7, 2015 at the Beeman Ranch on Road 95 west of Woodland. We had some rain about a week before, but the heavy clay ground was still a bit too dry for ideal plowing. At least this year, we were on safflower stubble, so we did not have any plugging problems. We plowed a lot more ground than last year and there was enough good ground to satisfy all who showed up. In addition to plowing, we also did some disking and dragging.
We would like to thank Greg Rieff, who is currently farming this land, for allowing us to dig up the soil a little bit. He appreciated that we opened up a bit of ground for him to seed for his haying operation. Greg also loaned us his forklift. Thanks also to Wilbur Reil for providing the signage as the field was a good distance from the road. Thanks to Mike Cristler for arranging the use of the land. See you out here again next year as this is a well received hands on event that is quite different from the rest of our show schedule.

Joe and Donna shared a love for animals. He loved cars, riding motorcycles, fishing, hunting waterfowl, rebuilding and restoring old tractors, and meeting up with his buddies at Starbucks. He was a longtime member of Branch 158 Early Day Gas Engine and Tractor Association.

Joe’s loving wife of 60 years, Donna, preceded him in death. He is survived by his three children and five grandchildren.

Joe’s hard work ethic, friendly and kind manner, generosity, and grateful spirit will be greatly missed.




Floyd Percival

by John Boehm

Floyd Percival passed away February 13, 2010. He was born in Meeker, Oklahoma on December 22, 1926 and grew up on a farm near Shawnee, Oklahoma. Floyd's parents grew corn, grain, hogs, and cattle. With all the chores that needed to be done, Floyd certainly was not spoiled. By the time he was ten years old, he was out in the field with a pair of bib overalls and a team of mules. Floyd still had the overalls to the end, though I suspect they were a few sizes larger by then. The Dust Bowl hit Oklahoma hard, so in 1938, Floyd and his father left the farm and moved to Capay, California. He married his first wife, then in the mid 1940's, his sons, Wayne and Jerry were born. He found work on a pipeline, then at a copper mine in Arizona. But a big, hot hole in the ground and no trees was a bit too much and he soon found his way back to California. He worked at various ranches in the Madison area for the next fifteen years. For a time, he also had a gas station in Esparto. In 1958, Floyd was remarried to Augie and they had five daughters. In 1959, he started work as a mechanic for the City of Woodland. He retired in the mid 1980's as the foreman of the vehicle maintenance shop.

Floyd never forgot his roots in farming. He was introduced to collecting antique engines and tractors by Cliff Hardy. Floyd joined Branch 13 of the Early Day Gas Engine and Tractor Association shortly after it was formed in the mid 1970's. Over the years, he served as Vice President for three years, President for three years, and many more years on the board of directors. More recently, he was instrumental in founding of Branch 158 of the Early Day Gas Engine and Tractor Association. He had been on its board of directors since 2004. He was also a volunteer at the Heidrick Ag History Center.

I first met Floyd when I joined Branch 13 in 1979. Then when we moved to Woodland in 1992, I really got to know him better. I started going in to the morning coffee group at Denny's once in a while. Floyd was always there and welcomed and encouraged me to come. Today I am still not much of a mechanic, but was really a greenhorn back then. Floyd always had the time to willingly and patiently show me how to do the various jobs involved in bringing an old machine back to life. Floyd really became a mentor to me. More recently, I got a grain binder and a threshing machine for our shows. Once again, Floyd was the man with the needed knowledge to set up and operate them. He took his time to instruct me, but I think he had fun getting the old machines going, too. I know that we will all miss his vast store of knowledge, his tales of how things were done in the past, and his helpful encouragement.

Floyd was a quiet leader who could and did get things done. For many years he ran the antique machinery display at the California State Fair Farm, coordinating the display, supervising all the helpers, and putting on a good show for the spectators. He was not content to keep doing the same old shows over and over again. Not one to sit around, he challenged us often by pushing us to start new events and expand older ones. For instance, six years ago, he told us that he was going to go on a two day 120 mile tractor drive, whether or not we joined him. We thought he was crazy when he first proposed it, but he persisted, and this drive has now evolved into the Branch 158 Colusa Endurance Run. Those of us who have participated now realize how doable it really was and that it was not beyond our capabilities. We have repeated this ride every year since then.

Floyd did start to slow down some in the past few years as health problems started to take more of a toll on his body. But he was active and alert to the end, just the way he would have wanted it. Even though he could no longer drive due to failing eyesight, he was usually eager to ride along when I went to deliver or pick up another old tractor. He enjoyed seeing the countryside and sharing in the discovery of some new old iron. Two weeks before his death, we found another tractor that he was interested in buying. We were making plans to take a look at it, when we found out it already had just been sold, so that was one that got away. He still had projects he planned to complete, ideas for the shows, and words of advice and encouragement.

Floyd was one of my best friends. And one could not have asked for a better friend. He was always helpful. I have never seen him get mad at anyone. Upset, maybe, but not mad. Floyd may not have been rich in monetary terms, but he was rich in the knowledge that he had of people and things. He understood how people thought and knew when they were not being honest with him, but usually did not let on that he did. He had a wealth of knowledge about old time farming methods and tractor and equipment repair. This knowledge he was willing to share and we have all learned much from him over the years. Floyd was a great father, grandfather, great-grandfather, and a true friend who will be greatly missed.

Oil for Old Tractors
Today's modern motor oil meets "SJ" specs - the oil that our old tractor engines were designed for something like SA or even earlier. Usually we get told that newer oil is better, but is it true? And if true, better in what way? Engine oil contains many additives, and the primary anti-wear and anti-oxidation additive is a chemical by the name of zinc dialkyl dithiophosphate (ZDDP). ZDDP, while good for engine wear and reduced corrosion is bad for catalytic converters. New oils have less ZDDP to make the catalytic converters live. But this is a compromise which results in more engine wear and internal corrosion. Older engines want a good big dose of ZDDP to keep engine wear down. New engine oil may be good for catalytic converters, but it's not as good for your engine from the point of view of reducing corrosion. Fuels of today often have oxygenates - MTBE or Ethanol - added to them. A trace of these oxygenates gets into the engine oil, and apparently these chemicals are tremendously corrosive, and they attack gaskets, seals, and certain metals. No problem for automakers; they choose new polymers and alloys that are immune to these attacks. But what's to prevent the attacks and the corrosion in older engines? For a seldom used engine, corrosion is a much bigger problem than wear, even the wear from starting an engine that's been sitting long enough to drain oil off most of its rubbing surfaces - because one little patch of rust on that same rubbing surface is doomsday.

While you could design a custom oil for this problem, the best off the shelf oil is 'heavy duty' oil intended for Diesel trucks. Instead of SJ, look for combinations that begin with C (for Compression ignition). CG-4 is the latest. While the oil part of these diesel oils has the same lubricating qualities as passenger car oil, the most common heavy-duty viscosity is 15W-40; more syrupy. But the diesel oils get bigger doses of additives; up to 80% more ZDDP, the anti-wear/anti-corrosion additive, and 30 to 50% more detergent, dispersant, and corrosion inhibitors. Good news if you have sticky rings, erratic compression, and blue exhaust smoke. This high-detergent oil will quickly free them up.For corrosion, heavy-duty oil is the silver-bullet solution. So, older conventional oils protect your older engine better than newer oils and the best modern oil for the engine of your old tractor is oil designed for diesel trucks!
