What a freat buy for plowing contractors with Curtis. Fisher. Western plows systems. Its really hard to beat up when plowing lots and roadwork plowing and maintenance threwout the storms. I purchased a few for back up. Dont use starter units it needs to be continuous soliniod type. Awesome product great price.

It's pretty good
Had a starter rebuilt/repaired at local stater shop and the solenoid that came with it blew out in nothing flat. Bought this one and so far it's been working for over a year.

Not happy with it 😩
I bought this starter solenoid relay for my Massey Ferguson tractor 1year ago this month. It worked fine until today , it shorted out and caused my starter to keep spinning! I jumped off the tractor because the key would not shut it down… I was able to yank the battery cable off the post before my starter gave out. I know it’s only a $15.00 part but could have cost me a new starter. I just ordered another brand , hopefully it will last longer 🤞
