I understand that some folks are not fans of combine derbys, but I'm looking for some help. We have a couple deere hydros and are looking to try to get more power and speed out of them. Those who have experience with the hydros, could you provide any tips. Is there an inverse relationship between gaining more speed and power? We've done the obvious and turned up the bosch fuel pumps to get more engine power. Not too concerned about reliability as we only run them a couple hours a year.



Also have a rear wheel assist axle off of a deere 7700 hydro serial number 261966H for sale. Includes axle, good tires, and valve body. Asking $1800 and located in Michigan zip code 48117. Also have parts off of deere 7700's, 6600's, 55, 45, international 915, 815, 615, gleaner E and M.



Thank you,

Nate
