Hey all,
The past couple weeks our 6220 Deere w/ PowrQuad Plus transmission has been experiencing what I would call a loss of power under load, e.g. when driving up small hills in road gear, the RPMS will start to pull down below 2000 and speed will keep reducing until it returns to flat ground; similarly, when out spraying in a field if I do a hard brake (w/ brakes unlocked) to reduce turning radius, it will very nearly kill the tractor until I remove my foot from the brake at which point the RPMS will very slowly creep back up and the engine will start returning to speed. The final symptom is that if trying to start from a dead stop (e.g. a stop sign) in the lowest 'road' gear (D1 for our tractor), it almost seems as if the tractor wants to die; if we start form a dead stop in a lower range/gear, e.g. C1, it will still be a bit rough but easy enough and then as it's rolling you can start shifting up gears and ranges. We've never had this issue with the tractor before. Once getting the tractor into the top 'road gear' (D4 for us), it will still not hit its previous top speed/RPM and any minor incline will slow it 1-2mph.
The tractor starts up just fine and does not blow out much/any smoke when starting and nothing when rolling down the road.
I have bled off what water/gunk I could from the tanks and filter and replaced the fuel filter, with no improvement. I have also checked/cleaned both engine air filters, which were replaced this past Winter (and normally last anywhere from 1000-1500 hrs). I also added some of John Deere's 'diesel fuel cleaner' type additive, with no apparent effect.
This 'power loss' was fairly sudden and happened when we were out mowing access lanes and became more noticeable when spraying.
Thanks for any advice and as this is my first post, if this is in the wrong forum please direct me where I need to stick it instead.
