kajamo240 3 #2 Posted January 7, 2010 If I remember right, it takes just under a quart. I run 5-30 in it all year... I don't know if that is best but thats what I do... :thumbs: Share this post Link to post Share on other sites
jdwheelhorse 0 #3 Posted January 7, 2010 If I remember right, it takes just under a quart. I run 5-30 in it all year... I don't know if that is best but thats what I do... Okay, the oil in it was probably 5w30 cuz it was really runny. and didnt look like much came out into my can. Okay thanks for the help. Would you happen to know what size air filter the B80 takes? I went to tractor supply and theyre all way too big. . . Share this post Link to post Share on other sites

Sparky-(Admin) 19,563 #5 Posted January 7, 2010 I have been saying my tractor is a B80 but i reeally havent a clue. It looks exactly like a 1969 model with a deere green paint job. The B-80 came out in 1974 as a 4 speed only and in 1975-76 with an 8 speed(hi/low). While your at Tractor Supply pick up some red paint . Mike....... Share this post Link to post Share on other sites
rmaynard 14,907 #6 Posted January 7, 2010 If it's a K181, 8HP, it takes 1 Qt. SAE 30 in summer, 0 to 32 deg. 10w30 or 10w40, below 0 to -20, 5w20 or 5w30. This is right out of the Kohler manual. Kohler Service Manual Bob Share this post Link to post Share on other sites
