With that code, then all we have to do is find this thread, look for post 19 to find the code, write it down and then fill in the correct info assuming we all had loaders, backhoes and ballast boxes and knew all the weights by heart, none of which I know about either of my tractors so it would mostly be blanks or ?????? all the way. By the way, engine HP and PTO HP are not a whole bunch different, usually 5 or 6 HP difference which in most cases of mowing etc can be differentiated by mowing conditions between heavy grass and light weeds. One can stall a 65 Hp tractor with a 6 foot BH in heavy cover if travel speed is too fast, therefore the old 5 HP per foot rule is just a rule of thumb. I have pulled a 6 foot BH with an 8N Ford (19 Hp) clipping pasture weeds in 4th gear(road gear) and no danger of stalling cutting the bitter weeds, but I have also put a heavy load on a 120 HP with a 6 footer also when going fast in heavy cover. Depending on your mowing conditions, you might run as little as 2-3 HP per foot or 15 Hp per foot.
