rret: Probably 99.9% of all intended uses on 3 point hitch requires no down presure. In fact most 3 point hitch implements would be damaged by tractor weight when going over uneven ground. The items that wouldn't be damaged like plows, disks, rear blades, etc. would lift the tractor's rear wheels causing it to loose traction.
I expect one could argue have down a down presure position on hydraulic control, and if that were the case it would probably be necessary to tripple the weight of 3 point linkage to withstand tractor weight. Couple that with the fact factory 3 point hitches are draft controlled and probably represent close to 12% of the total cost of the tractor. The 3 point hitch was designed as a precission control hitching tool, not a jack for lifting the tractor.
