you can find parts to Roper, Rally or MDT at EVERSHARP Power
Equipment, Inc.
Contact them @ 330.723.2428 or 440.582.2100
They've been in business almost 60 years. I'm sure they've seen just
about every tractor ever made and have parts to mowers dating back to
when they opened their shop in the 1950s.
