while doing a Frac job i could pull two and push one, i could winch and track all at the same time. I would use my elbow to knock the blade control into float as i was changing directions while turning into a new cut and by the time the blade was going into the ground i had it lined up for the cut and back on the blade control and the travel was already all the way forward, plum loved how it would do the ground speed to torque as the load came on and then pick speed back up when the load came off and you were carrying. I only knew two position of the direction control, all the way forward and all the way back wide open throttle. BUT IF you put the steering on the feet then you can steer change direction and control the blade all at the same time. While we were talking the one engineer asked me what i thought would be and improvement to make it better, i told him that to run it to it's max the operator needed three arms and hands, ya needed one hand on the direction control one on the steering levers and one on the blade. They agreed that she was NOT running right that is when old Al said here let me check and he put the gauges back on and tweaked here and a tweak there and another tweak, NOW she would throw rooster tails off the tracks and never slow down. we only ran for fifteen min.or so when i ran out of fuel and my pile was twice the size. Aske him if he knew how to cut a slot trench and he said yes, i said you take the 750 and i'll run the 450 as i have two slot trenches to make 200 feet lone and 6 feet deep and we will do this for 1/2 hour and we will see who can make the bigger pile of dirt a the end of the cut. This one deere guy and i got into it and i asked him if he could run it nd he told me he had over 400 Hrs running a 750. Back over to where they were standing and told them that she was a DOG and did not have what the 450 has. when done the guys from Deere went thru the set up and told me it was done go try it out, vary first blade i tryed to push she had no getty up and go. I had moved in the 450C to try and get the job done as i was running out of time. I was on a drilling location build when it went down. When the charge pump went she had like 250 Hrs on it and when the mechanic from the deere dealership arrived also he had 6 people from deere that flew in with the parts and also dove in with the repairs as they had to pull parts from the line. Once i figured out how to run it i was impressed with it. of five drilling rig locations a week five entrance ways and atleast one drilling rig move. I ran one of he first 750 J D's in the oil patch, equipped with a W6 F Hyster winch with 1 and 1/8 blue wrap drill line over the 7/8ths that was what was suppose to be on it it built on avg. i did have and issue with a charge pump on it. You would think if those Hydros were bad i would have found the weak points. Re: John Deere dozer hydrostatic drive rebuild in reply to jm., 06-30-2021 18:14:04
