stevasaurus 22,857 #2 Posted January 3, 2022 Yes, but you will have to do some cutting on the plate to fit the hi/low shifter. Share this post Link to post Share on other sites
ri702bill 8,486 #3 Posted January 3, 2022 Ah, but WELL worth it !!! No regrets with my 854 8 speed. Bill 1 Share this post Link to post Share on other sites
Achto 27,750 #4 Posted January 3, 2022 633 is still on my radar. The 653 came with a Tecumseh engine, the 633 is basically the same tractor but with a Kohler engine. 1 Share this post Link to post Share on other sites
Pullstart 63,090 #5 Posted January 4, 2022 My 502 “Putt Putt” has a C-101 transmission. Your brake linkage will be different and you might not be able to keep the parking brake lever. Also, some clearance required for the hi/low shifter and dipstick tube. Share this post Link to post Share on other sites
Pullstart 63,090 #6 Posted January 4, 2022 Also, the input pulley shafts are different size and the pulleys are different diameter too. 2 Share this post Link to post Share on other sites

I'd love to see some photos and hear about how it went. Edited January 4, 2022 by Handy Don Share this post Link to post Share on other sites
