So the machine exceeded our expectations.
It's been used in a mix of wood. Very quick machine. I spoke with the operator Friday to see how it was going and he said "great! we've been pulling 3 foot tree length cedars all week". Not bad for a 3/4. Variable speed fan is dealing with heat well as it's warming up. Fuel burn is around 10L/hr in typical second growth. Basically starts and runs for them every day.
Changes we've made (fitted to #1 and going forward):
* Auxiliary air compressor. It will be a rotary vane type. We have a predetair in there as a temporary solution but the duty cycle is a bit high for that
* Variable swing pressure up and down - so it feels like a closed loop swing circuit. Works nice
* Seals - namely around doubling roto unions. The copper washer is gone.
* Door latches - those little stainless flappers just weren't going to work. Heavy duty T-MAR ones on there now.
* Software updates to add some features and data logging. The request list keeps growing but it's easy to manage with this layout.
That's kindof it. Lift is good, spooling is good, speed is good, crawler is happy, cooling is good, shifting is nice. #2 is well underway.
