Bushing for snowplow angle pivot

[500K_773]

This is not really a repair question, but rather one about building attachments. I want to build a snowplow blade out of a section of 36" pipe that angles 30° left and right. I have found the pipe, cylinders, etc... but am having a difficult time finding a bushing for the blade pivot point. Does anyone know where I can find a bushing that will work in this application? I know I could just drill a hole in some steel plate and run a pin through it and it would work, but I rather have something that could be serviced easily in the future. I know Bobcat sells a snowplow angle blade, but it is ~$3000 and I can build one for less than $1000.

How about checking some farm tractor supply places and looking at the bushing that they use in a three point hitch? Pretty strong and pretty cheap. Also, perhaps front end parts from a car or truck. Steering parts, such as kingpins, ect......Since it won't see any high speeds and very little travel over time, you could make a bushing and add a grease fitting. Let us know how you do it as I want to build one too.

First of all, I haven't found the exact bushing I was looking for, but did find some good information for some plans. Here is a link to a manual for a snow blade for a skid steer that has a good diagram that you could use for making plans. http://www.sweepster.com/pdf/man/SnowBlade_Manual.pdf

There are 3 models in the manual for different size machines. The manufacture's website has good descriptions to help you pick a model to fit your machine. http://www.ffcattachments.com/pdf/snow.pdf I really like the pull back feature on the snow push they make and will probably design mine like this model.

For my machine, I believe I need a pin for the pivot point with a minimum diameter of 1", but a 1 3/8" or 1 1/2" would be better. For the angle cylinders, 3/4" diameter should suffice. I did find a 3/4" bronze bushing at Grainger.

I'll update this if I find any bushings for the larger pins. If you have any suggestion, other than buy a pre-built one

, please let me know.

I wouldn't see any point in having a full length bushing for the pin, but maybe a 4WD farm tractor in the pivot area would come close. White Farm Equipment used a fibre bushing that has a full length slit in it that can be trimmed to fit fairly easy
