Long title but its to the point.
In my quest to get a BX23S for myself, but yet under the gun for a project, I rented a BX23S ($219/day, rent 3 days, get it for 7 days, $150 for delivery, plus taxes. Extra charges if used more than 40 hrs on machine for a weekly rental, and if not returned with fuel... in case anyone was curious).
Its a great little machine. Fits my small half acre property perfectly. Was able to move several tons of earth and stone, dig two trenches and grade. I put on 30 hours over 5 days. I have one or so day left before needing to clean up and refuel for rental return.
Starting is not an issue, she fires up fine. Backhoe and loader use, no issue.
Here's the issue: When using the hydrostatic drive to move forward and backward, intermittently, the RPMs drop dramatically and go to stall, unless I release the forward/reverse pedal. Was on a hill initially, happened once on day 2 while reversing up a steep hill, but yesterday (day 5, happened several times, regardless of hill or no hill). When this issue pops up, I can still move forward, with a very very light feather touch of the forward pedal, near idle speed. Any additional forward press on the pedal would dip the RPMs, which I would just release the pedal and she'd idle happily. With reverse, same deal, subtle press and she'll move backwards, but press a hair more, RPMs dip to stall. Let go and idles fine.
I thought perhaps there was a fuel issue. Maybe being on a hill with low fuel would starve the engine under load? Gave it a full tank and it seemed to work fine, but then it happened again.
Sometimes letting it sit would 'solve' the issue, and it would travel as normal. Then maybe an hour later, symptom returns, PITA for maybe 15 minutes, then back to normal like nothing is wrong.
Searching this forum, it seems to be a fuel delivery issue. Blocked line maybe? Perhaps a bad fuel pump? Not sure. I cannot do much as its a rental, but still something that I am curious about. If its a fuel delivery problem, how can it idle fine but just the mere forward/reverse movement and it wants to stall? Is there a hydrostatic issue here?
