I have a four year old Honda HRM215 walk behind mower (Harmony with plastic deck). It is the blade-brake-clutch variety. It has been a great mower except for the self-propelled drivetrain. Last year the rear pulley stripped so I replaced that. Now I need to replace the drive belt (keeps popping off due to edge wear, I assume from last year's problem). So I've gotten the belt but can't figure out how to get the old one completely off and the new one on in it's place. The problem is the blade brake assembly at the engine shaft--there's not enough room between it and the deck assembly to fit the belt around. The other end is no problem. There's a large bolt in the middle of the brake assembly that obviously goes into the engine shaft as when I turn it it just turns the engine. Does anyone know the magic disassembly procedure to get to the belt on these mowers? Thanks in advance.
