It takes little power to start or drive a tractor. Using the PTO takes a great deal more. Disconnect the fuel line near the tank and try to drain fuel into a container. The flow should be steady and not diminish. If you only get a dribble you may have a blockage in the tank. You may also need to replace the fuel filter then bleed air out of the lines.
she seems to go great for about half hour but starts lossing power she will drive up one side then when you turn and go other way she drops in power i cut football pitches its very level
