I'm with Royse;
Pie weights and fluid.
A 3 point tractor with the 3 point impeded by a weight is only half a tractor. If you can't afford pie weights maybe mount something to the axles.
I used to have a 2N that I built a snow plow for. Inner wheel weights weren't enough so I bolted some elevator weights onto the axles. They added 300 lbs per side.
