Hi Jeremy.
Yes indeed the hot water power washer are nice to clean your tractor plus attachments,and I set mine at 2100psi also make sure that the muffler and air cleaner cover well.
If your only planning to use a hot water washer for your tractor and attachments than the cost I would consider.
I use my hot water washer for number of jobs,wash the house,barn,tractors,attachments etc..
By the sounds you live well with in the cold belt line as I do.
I use to wash my tractor at first during the winter time,but even after wiping them down there was still pockets of ice built up....mmmmm.
I have only a cold barn to store my tractors,so I use window cleaner and rags to keep them clean until spring.
Have you check Grangers catolog?
I believe they have a website.
Have fun and stay safe.
