    Hydraulic pump shop is unmatched. I made the mistake of going somewhere else before bringing my pump here. These guys were more than helpful and friendly. Went out of their way to help me find a solution for my problem even when it didn’t benefit them. This is how businesses should be run. I won’t go anywhere else.

    Too bad Poole Cat Field Service is better at invoicing than actually getting my machines moving.

    A prompt and courteous technician arrived, and correctly diagnosed two problems with my mini Ex. Thank you. I corrected those problems, but machine still did not work.

    He diagnosed a fuel problem as a clogged filter, rather than a bad fuel pump which I managed to diagnose. I also figured out, via help on the internet, that the fuel shut-off solenoid was bad.

    Machine runs fine now. So my advice is to check the internet, before letting Poole charge you $870 for a two hour field visit. And you can find a perfectly fine aftermarket fuel pump for $20 rather than the $250 that Poole charges... and it arrives faster,

    Need to teach a tech how to drive a service truck. Around 2:48 on highway 40 east, the truck pictured (plate ending in 8236) flew across 3 lanes of traffic to meet the Cleveland rd exit. Almost hit a semi and caused me to swerve with my children in the car. Glad making the exit was more important than children’s lives.
