RTR2072 Chain Break Fix | Land Pride Tiller Repair

Hit hidden junk in the field and snapped your Land Pride RTR-2072 tiller chain? Same here. In this video I tear back into the gearbox, diagnose a broken #80 chain, fish out metal fragments, repair the run with master links, and button everything up so we can get back to building our riding arena.

You’ll see:

How to safely open the chain case and preserve thick lube

Inspecting sprockets for damage after a snap

Identifying bad links (loose/bent side plates, missing peened pins)

Grinding pins, removing damaged links, and installing #80 master links

What to do when a master link clip won’t seat (tolerance workaround)

Reassembly, tensioning the idler, and test passes
