I have just acquired an 810A 2 x 14" plow.

How do I tell if it has "Regular Trip Back Standards" or "Increased Trip Back Standards" ?

I never used one of these in my plow days and can't seem to figure it out from the parts book.

Thanks in advance for any help. HerbN

Got to wonder my 810 2 x 16 have the replacement sleeves to increase the pressure it takes to trip them,might be reg or increased

Here's the answer I got from David Wolfe, author of 2 popular plow books.

Herb- The 810A will have increased trip back standards since it was made 1958 and later. I don't know what to tell you to look for to identify the trip mechanism. I have a lot of different part numbers that will only confuse you more. The plows without increased trip back standards used a tail wheel axle - Part No. WX922A. This is shaped like the letter Z. The plows with increased trip back standards used a rear axle - Part No. AA10629A. This is shaped like the letter C or U. Dave

Hope this helps if any one else was wondering. HerbN

Herb,I for one would be interested in those books by David Wolfe,and the parts info for the 810A.Our local JD dealer owner George of Hall's Implement has printed off parts info for me to pickup sometime.Very curious to know the difference.Mike Ross

Mike: Go to the JD parts site--

http://jdpc.deere.com/jdpc/servlet/com.dee...PageServlet_Alt

Put 810 in the box, then select 810 plows, then select ID View on the left of the pfd.

There's about 4 pages of different plows. You'll be able to see the difference in the furrow wheels Dave mentions, bookmark this site, you can get most any part book you want here.

His first book was "Plows & Plowing", and the second "The John Deere Moldboard Tractor Plow", 1944 to 1960 The two Cylinder Era.

Dave works away but is home on weekends. Email: bedacompany@yahoo.com . His wife will get right back to you with info. on book cost etc.

I layed the two different parts pages side by side and checked everything by description,cannot see any difference.Would like to have a sample of the side plates to compare.Next step is the book.

Mike, The later models with (Increased trip standards) (810A) have a C or U shaped axle on the furrow wheel. (Depending on how you look at it)The earlier 810 regular trip standard models have a Z shaped axle on the furrow wheel. Just look at the rear end of the plows.

If you have the old style tail wheel assembly, the one with thw Z shaped axel, be careful about the landside you use on the rear bottom. The origonal short cast iron landsides are subbed up to the new two piece style landside with the replacable block on the heel. When the rear bottom trips the new style landside hits part on the tailwheel linkage and breaks it. My 812 plow suffered this problem.

Thanks, I will check it next season.Mother Nature has controll of us for a few months now.
