F 20 speeds

Another B Puller · Feb 7, 2012

I am building a F20 for tractor pulling and want to know what the MPHs are for the gears. Just need to know what corn picker and 1st,2nd,3rd,4rd are. Thanks for all the help,I know this will change with tire size.

I read this in a book and am going by memory:

1- 2.25 mph
2- 2.75 mph
3- 3.25 mph
4- 3.75 mph

I believe these were taken on 40 inch steel, but I can't confirm it. Low speed attachment has a ratio (16:36) and the faster first is (18:34)? by memory. I don't have my parts book with me.

If you're going to be pulling around 5500 or 6000, the low speed attchment may be a good addition. From what I have seen, I believe that the standard first will slightly exceed 3.5 mph. If you need any gears, I may have some extra sets.
