Coupler on MTD snowblower busted....

[Castleford]

Was just reading your update. Thanks for the follow up!

Princess Auto has a line of pretty inexpensive jaw and/or shaft couplers that I will probably entertain next time I find myself up against this issue. Have been running the snowblower pretty hard this year, lots of blown in packed snow.

I'm more concerned with the transmission on my poor little tractor. Gonna have to look at a fluid change soon I think. Its not really designed to be changed...

Yeah I changed the oil in mine a few years ago, wasn't easy but doable with a manual vacuum oil extractor.
I bought a used running attachment locally for a backup/spare parts and while looking it over noticed the Lovejoy coupling on the backup was substantially larger than the one I was running.
The attachment I was running has a "L075" size coupler and the replacement /backup attachment has an "L090" size coupling. The torque rating on the larger coupling is over twice that of the smaller one,561 in lbs vs 227 in lbs.
Either the manufacturer upgraded the coupling or a smaller one substituted by accident during a repair, either way I'm buying the larger coupling, I measured both and they're interchangeable between machines.
