I just bought a 2014 L3901 HST and while cutting pasture with rotary cutter it began to stall. If I released the pedal or depressed the clutch in time it wouldn't stall but as soon as I tried to move again it would stall. Disengaged the PTO but problem continued. Transmission seems hot but fluild levels were fine. If I let it set for 10 minutes or so it would run for a while and then start the same problem all over. Any ideas?
2014 L3901 HST Stalls
- Thread starter SpeedyMC
- Start date
Didn't mention this before but tractor only has 3 hours on it as of last night. Doesn't seem to be a fuel issue as it starts right up and will run without a problem until I hit the HST drive then stalls, even with PTO disengaged. Checked the transmission fluid level again and it's topped off, was hard to check in dark last night since it's clear. I'm beginning to suspect the switch under the seat. Not sure I there's a way to adjust it or if I have to take it into a dealer. If I have to take it to a dealer after 3 hours of operation I'm going to start regertting buying Orange.
Move the seat way forward so more weight is on it. My better half didn't want to move 'my' seat and had the same problem at first. I told her it's just a seat...I put hers back down.

Seat safety switch is out of adjustment.
Look at it most are a simple adjustment to make it engage better.

Sounds like a seat safety switch to me. Great idea to check the parking break too! You may want to drop into Low and put in 4 wheel drive ,do the same task as when you stalled and see if you were loading the HST too much. Let us know if this gets you going.
Wasn't the parking brake, that was the first thing I checked. I'm really not sure what it was but yesterday I spent 2 hours cutting without a problem. Only thing I did different was to move the seat forward and then all the way back again (6'3" so I need the room). I'm not sure what was different yesterday but I've got about 4 more hours of mowing to do today so I'll see how it goes and let everyone know.
Well after moving the seat forward and then all the way back again I haven't had the problem again. I'm loving the new L3901, perfect size for my 14 acres.

It's a very common problem for the seat switches to get out of whack.
See no need to regret buying orange!

Yup, when they dropped mine off it had the same problem mine has 6hrs on it now. My first tractor with all this safety stuff on it. I took a black wire tie and tied the switch down so it won't matter if I lean to the right on the seat anymore. Probably not the safest thing but it works fine.It's a very common problem for the seat switches to get out of whack.

I disconnected my switch also. Mainly so I could use the wood chipper, and it also fixed when you just needed to see where the bucket is and inch up to something.
Becareful of disabling safety switches, in a roll over/accident, etc it could enable the tractor to be still active causing more injury or a death.
I understand you must do what you need to do but think before you do.

Here's another data point for the 3901 and the seat switch. Mine kept "stalling" too but it wasn't until I thought about what I was doing (occasionally standing up a bit to get better visibility) that I found out what the problem really was. I've also noticed that when cruising over bumpy ground, my up/down movement in the seat is enough to make the tractor hesitate.
I haven't done anything (yet) to alter this switch, but just knowing that I need to keep my butt firmly planted in the seat at all times goes a long way to preventing that stalling feeling.

I like the safety aspect of the seat switch and don't plan on bypassing it, but I do find it hard to standup and put the seat forward when running my Woodmaxx PTO chipper. I find if I turn while I'm standing and put my right hand on the top back of the seat I can keep the switch in the butt in the seat mode and then get out of the way to put the seat forward for the running PTO mode.
My seat bottom is metal. a shim under the switch or above may help with the issue, keeping safety 100%.
