I have a Landini 2840 H (hydrostatic) tractor made by LS

Customer Question

Hi there
I have a Landini 2840 H (hydrostatic) tractor made by LS tractor in Korea.
Periodically it will stall and continue to to stall out when you try to move it forward or reverse. Today I also noticed it stalled when I tried to engage the PTO.
Initially when the stalling started today you could just restart and gently move forward and it would be ok for a while.
As the day progressed I wasn't able to move the tractor at all without stalling but there was no trouble restarting it.
I did notice a noise like a switch tripping right before it stalled.
Finally I got fed up , disconnected my trailer and moved it about 1 foot a minute and put it back in the shed.

Hi Jamie. My name is***** will be glad to try to help. Check the hydrostatic filter for fine metal/debris and suction screen that would indicate a pump/hydrostatic drive failure occuring. When the engine is stalling from your description it sounds like the hydrostatic drive is pulling an excessive load on the engine. Let me know.

I've checked the filter
It was changed about 300 hours ago.
The tractor only seems to do this after extended use.
If I park it when it starts acting up and then use it the next day it does not ha e this problem.
I do not use it contually day in and out so I do not get the chance to see if it repeats but this has happen a few times in the past

When you say the oil screen are you referring to the screw in filter ?

here is a picture of the filter I checked
I'm not sure if the black cyllinder device contains another filter.
I think I'll need a strap wrench to remove that.
Customer: replied 5 months ago.
Both filters were removed and visually inspected.
No debris is visible and the oil looked clean.
The tractor currently has 360 hours on it
The filters were changed at 50 hours as per manufacturer spec.
Hydraulic service interval is every 600 hours.

Thanks for the update. Check the seat switch, PTO switch, and clutch/brake switches and harness for faulty switches or wiring which will cause the tractor to shut down. Also check your fuses and relays. Try bypassing the switches with a jumper for test purposes.
