Lockupchuck 7 #1 Posted July 8, 2020 (edited) I believe I have a rj-35, or 85. Can someone help me with location of serial #s on frame, and Kohler 4hp serial# as there is several coats of paint on this Tractor, so I know exactly what I am working on? Thank you so much I believe it is a 50's Model Edited July 8, 2020 by Lockupchuck Added text Share this post Link to post Share on other sites
prondzy 3889 #2 Posted July 8, 2020 No serial numbers on the frame tractors that old didnt have serial numbers. 4hp kohler most likely a k90 or k91 serial tag would be riveted tk the flywheel shroud on the carburetor side. Post pics of your tractor so we can help you identify it. 2 Share this post Link to post Share on other sites
bottjernat1 2194 #3 Posted July 8, 2020 I have a restored rj58 they put a tag on the frame on the rj58 and 59 models and on up. If its a 58 or 59 and looks similar to mine there may be a tag on the frame on the left side in front of the motor 4 1 Share this post Link to post Share on other sites
bottjernat1 2194 #4 Posted July 8, 2020 (edited) But the best way to find the year would be by the metal oval tag by the shifter. The should be a tag there it will be short numbers and a letter. the last number if i remember is the year the tranny was made. If it looks like mine look for a 8,9,or 0 on that tag by the shifter. if its older im not sure and the tranny will be alot different.

Lockupchuck 7 #7 Posted July 9, 2020 A Co-Worker got this ad a gift from his Father when he was 7 yrs old. They never could get it running. His Father has soon passed, and he asked me to look at it. The 4hp Kohler (I think) had 100# of Compression, but no spark. 2 Share this post Link to post Share on other sites

bottjernat1 2194 #13 Posted August 5, 2020 @Lane Ranger Is correct. 1959 The last digit is a 9 so that means she was made in 59. At least the transmission was. Share this post Link to post Share on other sites

My restored rj58 is a 4hp kohler Early 58 and some 59 had clintons tho. Share this post Link to post Share on other sites
