Hi Flying 444, if you live in Canada there should be no problem getting parts as the B414,434,444 and 384 (all the same tractor with slight difference and different sheet metal) were the most popular 40HP utility tractor in eastern Canada. My brother had a 384 up till about 1991.
Looking at the pictorial representation of the hydraulic system in the B414 Operators Manual, your problem of the hydraulic constantly wanting to lift has to be either the up/down control lever mechanism or the draft control system.
I suspect the draft control system. I was wondering if the draft control sensor is stuck.
This is a stainless steel rod that comes out of the hydraulic reservoir housing right behind where the top link hitch pin hole is. When you move the draft control lever all the way forward the sensor should retract into the hydraulic housing. When you move the draft control lever upwards the sensor should come out and touch the top link casting. This is the feedback sensor to the draft control system along with the spring that is in the top link housing. If the sensor is working OK and you only use the 3pt for bush hogging, there is a possibility of making a bypass circuit.
