ON THE GOOD DAYS THE BREAKDOWNS ARE MINOR. In this case the fix was not as substantial a process as it might appear.
This picture was taken a week ago. It’s our Oliver 1750 Diesel, which for the last three years we’ve used to pull our ‘Juko’ Potato Harvester. This Fall we noticed the hydraulic power was not as strong as it was last Fall.
Caleb first tried an old Oliver-hack and disassembled the spring-loaded Hydraulic Pressure Relief Valve. He carefully placed a 3/8″ lock-washer into the spring-pocket before he reinserted the spring-driven Pressure Relief Valve. Half the time this trick will work to take up the slack from a spring which is not as young as it used to be. When we tried the tractor the next day digging, the hack didn’t give us anymore hydraulic power than what had got us worried.
Later that same afternoon, with Justin helping him, Caleb used a forklift to lift off the 400-pound assembly which contains the hydraulic pump. This assembly is bolted onto the Rear End of the tractor. The tractor seat mounts atop the assembly.
Earlier in the day Caleb had located a replacement Oliver assembly with used hydraulic pump – thought to be in good condition – at a junk yard across the line in Canada. Megan had her papers handy, so she logged onto the computer and filed for a Canadian crossing permit and she went over to bring it home.
Everything went smoothly and soon after dark Caleb and Justin had installed the replacement assembly.
We were able to start digging on-time at 7am the next morning. Turns out this used Hydraulic Pump has more life to it than the 1750’s old one ever did in the five years we’ve owned it. The hydraulics are now working great and we only lost a couple of hours worth of digging.
We like owning equipment we can fit. This practical independence is what Jim was trying to convey in his testimony before a Congressional hearing last week.

“‘We rely upon older equipment going back to the 1970s — equipment that we have repaired and rebuilt ourselves. We would never choose to place ourselves into a vulnerable position of being at the mercy of malfunctioning electronic sensors… When a problem as common and as minor as water condensation in a diesel tank can cause a sudden ‘limp mode’ activation, say during peak planting or peak of harvest, not only does that place an individual farmer and our livelihood at risk, but it really places the nation’s food security at risk,’ Gerritsen said.”
