When I had a 3pt on a Gt I had a dirt scoop for it. The tractor was a JDx475 which is a big tractor with 26" wheels similar in size to the 1655/1855 Masseys. It had a limited cat 1 hitch and the scoop was a standard 24" Cat 1 from a company called Worksaver. I moved a lot of gravel with that scoop for building trails around my property. I always called it a poor mans loader. Here's a picture of it with a large rock on board.
When I bought my Ford 1500 it came with a Category 1 King Kutter Dirt Scoop. I have to admit I was skeptical of it's usefulness?
After moving I don't know how many tons of dirt with it I have changed my mind!! It is a very useful item and I would not be without one.
Now I don't know if your a gardener? But A Hiller is a very useful attatchment for raising beds, laying furrows or hilling potatoes.
This is not mine(swiped picture off the net) It looks to be on an N Ford, but I have seen nice ones scaled down for the GT.
My Dad built me one and did a good job. I used it enough to prove it's usefulness. But my idea for shank clamps did not pan out well and I will have to revise that before I take pictures. I now have a welder so it will be amoung the first projects I tackle.
And since I am getting old enough that Running potato Forks and Spades are too much work. And I like to grow lots of potatoes, this is about the best $125 I ever spent. I can dig a 70 ft row and pick up all the potatoes in less than an hour. I also use it to plow my garden.
Again you could scale it down to tfit your Gt.(lpaste did not work, be back shortly).
Also this is not my Tractor (but simular), anothe picture off the net. Come to think of it I do have a picture of my tractor after I plowed last spring.(above)
Forgot to put the text in before I posted the picture. The Landscape rake is very nice. When my 1/4 mile lane does not need shape grading this is the perfect tool for redistributing gravel and pulling up gravel from the packed tracks. You can buy the tines and make one to fit your GT. This is turned around in the picture because I used it to top off the ridges in the first picture above before runnng the tiller over the plowed ground and wanted a less agressive(moving too much dirt). attack angle.
I started with the Sears 3pt stuff, it has been converted over to the standard Cat 0 spacing now. The Sears 3pt is narrower than the standard and the top link connection is different also. Sears is easier to find than standard cat 0. I have Potato plow, Mold board, Tandem disk, Back blade, tool bars setup for hillers and cultivators. I just built a small sub soiler for it also. Future builds are Lift pole, Box blade and carry all.
The one with the little plow and big plow shows the difference in Standard and Sears Spacing.
