Thank you for replying. New to posting so please bear with me....
Our place is raw land - only land, ha ha. No water source, no electricity, no sewer. I guess we are about as "off-grid" as one can be. We camp. We have been doing a few little low cost projects to collect water and make a composting toilet. As for a shop? :laughing: there is none and there won't be one for some time to come. (Saving up for one) All work done outside, in the open, on dirt and grass. We just have basic tools. Have been using a walk behind brush hog and a 7 HP self propelled lawnmower to mow trails. We've mostly been using a lawn cart to move things around, we are the "mules" - really big stuff goes in the truck bed.(yes - we get plenty of exercise doing this; after many years of doing this we have finally purchased a small tractor)
Now to the 1025R:
Wheel weights are a 70 lb then two 50lb weights for each tire. On the outside you add the 70lb one first, attach a second 50 lb weight, then on the inner side attach the third weight of 50 lbs.
This video shows a man doing this to a 1025r but he is using a different weight. The video is good to see the inner side of the wheel:

This man adds similar weights to a larger tractor using leverage to his advantage

I can lift 40-50 lbs being careful. over that needs to be "bear-hugged"
We will be purchasing a heavy hitch for the back PTO with the 8-40lb suitcase weights. Once the wheel weights are on, we don't plan on removing them. Most of what we will be doing needs counterbalance and the wheel weights add to the low center of gravity. If I need more weight, I can always work with the brush cutter attached, but would like to have a smaller footprint for maneuverability.
Tire
ballast isn't an option for us - our trees are mostly bodark(thorns), Honey Locust (larger thorns) and Black locust (4-5" thorns - and no, I'm not exaggerating

We haven't been able to keep our cheapy mountain bike tires from getting punctured... Even with slime...
Thank you for your time!
