Howdy,
We have a 2004 Kubota L3130 HST with 1300hrs on it. Been a reliable machine until the last few hours. We have noticed the engine bogging down more and more. The engine bogs similar to when you push too hard on the pedal when its cold or when in too high of gear range, except when its doing this it can bog in low range on even a small hill. It is hit or miss tho, like when moving dirt with the loader some movements its bogs worse than others. Another weird thing is when its bogging on say flat ground if mid engine bog with the pedal forward I go from forward to reverse the tractor will then not bog in reverse. Reverse clearly does not bog as easily and nearly not at all.
Some info and ideas:
1. Some might ask if I know exactly how to operate a HST, I have many hours on HST equipment so this is not an issue.
2. Fuel filter looks clean and engine runs well other than the bogging. For example the loader and backhoe have plenty of power.
3. Both the hydraulic and transmission filters are roughly 100 hours old, however the backhoe has some heavily weeping pistons so maybe backhoe use has something clogged.
4. When we blew a hose one night the only tractor fluid we could get was the Navi Guard Universal Tractor Fluid NAV TRACTOR HYD FLUID 5 GALLON PAIL Napa said it meets the Kubota specs a long with many others so hopefully this is not the issue. We added about 2.5 gallons of this 20 hrs ago with the bogging issue starting just about 2 hours ago.
Updated: When the issue first started and before I tried it in reverse I thought the parking brake was stuck on, but tires spin by hand when I jacked it up with the outriggers.
Any thoughts on where to begin? If it was a clogged filter it should effect the performance in both forwards and reverse, no?
I am a decent backyard mechanic, but not with trouble shooting issues like this.
Thanks!
