Check your hydrostatic filter, they have been known to be plugged with lots of chips on the outside of the filter before the oil goes in that's what the magnetic ring is all about. Also check the oil level in your hydrostatic transmission body. If it's low it might not be picking up any oil.I have several hydrostatic machines and I'm fully familiar with how hydrostatic machines work. I bought an L3901 a couple year ago and haven't used it too much (because, as noted, I have other machines). However, this year, I got the tractor out and it was time to see what it would do. Which, to my surprise, isn't much. To put it in perspective, I must run the tractor in low range for ANYTHING other than basic travel across mostly level ground. Even in mid-range, if I stop on a small hill, the tractor will barely take off. I'm aware the tram peddle is not a gas pedal...it operates more like a gear box...applying a little tram will give the most torque, etc. But the main thing convincing me the tractor may have a problem is its behavior. Specifically, I can't make the engine "bog down" under tram load. For example, if I try to start off on a hill in high range, the engine does not complain even though the hydrostatic transmission is whining away and the tractor isn't moving. Ether the engine has so much power it can engage the transmission pressure reliefs with ease, or the pressure reliefs are set too low (or, the transmission has a problem).
I'm posting to get the experience of some other 3901 owners. Does this sound normal to you? When in mid or high range, can you bog down the engine when attempting to take off or transverse on a hill that's too steep? Before I take the tractor in for service, or trade it for another model, I’d like to get an opinion as to whether this experience is normal for this tractor.
