I have inherited a 5045E in 2012. It is a great tractor for few hours. I want to buy a Woods Batwing. Requires 34hp in the PTO. This tractor produces 37HP in the PTO. I know enough to know that it will not work pulling the hills where I live (unless I drag me). I wonder if someone has succeeded by tuning it to increase the HP. I think an extra 15hp would work.
Most power increases are created by alteration of turbo performance parameters and increased fuel rail pressures. If you do not have a turbo engine, you may not get a lot just with the tuning.
The 5045E 2012 uses a motor of 3 cylinder 2.9 L with mechanical and turbo injection. The pieces lists have about a dozen different listings for the “engine” so it is not clear if there is any difference in the parts for your 5045E vs 5055E, 5065E, 5075E, or if the performance increases are simply by the Increase in the feed rate as set by a screw in the injectors pump or with the adjustments of the turbocharger discharge valve, if equipped. It is not clear if there is a discharge valve in the turbocharger of a Tier II 5045E, I did not see a separate list of the turbo as they do with the subsequent models, and if in fact there is an integrated with the turbocharger, one could only guess if It is adjustable.
The best estimate is that the 5045e, being a nominally 50 HP engine, actually around 44-45 HP in the power outlet that is officially classified. Nebraska did not prove that tractor year, but proved the predecessor, the rear 5103, which had a nominal power of 50 HP and a similar engine configuration, if not identical, to the 5045E of 2012. 44 HP in PTO a The nominal speed of the PTO and 46 HP maximum in the PTO, which is more or less as it can be supposed for a 50 HP engine, since the losses in the transmission line are generally <10% for a modern tractor. It is known that Deere significantly underestimates the strength horses of the PTO in the last 3-cylinder tractors with turbocharger, as evidenced by the power figures universally higher than the nominal in the models that Nebraska proved.
A batwing weighs in the range of two tons, and is on the wheels, which should not be so big of a problem for a 5045E to physically pull on the hills that are safe to operate the batwing in. The real job is to spin the blades, which may require a lot of power. The amount of power that is needed depends on the size of the batwing, of what is being cut and the speed to which you want to cut. The general rule is 5 HP of motor perpetrator for the “medium” work, around 7 hp / foot for high brambles, and 3-4 cv of motor per foot for light work, such as the trimming of pastures of The grass bushes that the cattle did not eat. It should also be borne in mind that the rotary cutters must remain in one place long enough to aspire and crush the remains and then spit them, or they will do a lousy job. Either the material is hit and passed over, leaving it largely uncut, either the mower is stuck when entering the material faster than it can spit it. The speed at which you can go is directly related to the amount of material that passes through the cutter, but in general you can not exceed 5 mph even in light conditions.
