Hi Richard. Don't sell yourself short. A 3pt hitch is a very handy option. All of my 3pt accessories do not require a PTO (mostly because my first tractor having a 3pt was my 140, and a rear PTO with the 3pt was not an option). To give you an idea of other things beside a box blade or rear blade you can have a tandem disk
12" plow
Cultivator
By using a 3pt to sleeve hitch adapter you can use all your easier to find integral hitch/sleeve hitch style attachments
And, you can get fork lift forks to fit the adapter which is handy for moving attachments around
These are just examples of equipment I own, and there are plenty more that I don't. Personally, a 3pt was the first attachment I added to my "new to me" 318 last summer (right after putting on a set of rear bar tires
).
