Kubota GR2120

[cchapman5190]

I have a Kubota GR2120 mower.
It starts and runs fine. The PTO engages the mower as it should but, as soon as step on the pedal to go froward it bogs down
I have changed both fuel filters and the hydraulic fluid filter. That didn't help the problem.
Any advice would be greatly appreciated
Thanks in advance

Did you find an answer or resolve the issue with your GR?

I have a GR2110 with the same problem! Did you resolve your issue? What was/were the culprit/culprits?

What bogs down? The mower or the engine speed?

The engine speed bogs down.

I would first make sure nothing is binding with the deck or deck PTO shaft. Then I would focus on the reverse safety system. My 2100 "bogs downwhen I engage the PTO and move in reverse without first pressing the dash button to disable the reverse safety system. I wonder if the switch is loose or going bad.

Thanks for the suggestion. I'm not very convinced that it is that system as the symptoms I am having are nothing like the abrupt cutoff of rpms that I get with the anti-reversing system.

I read that these low sulfur diesel formulas have a considerable amount of paraffin can "drop out" of suspension at pretty warm temperatures. We had a short dip in temperature in mid November and I'm thinking that maybe my fuel filter(s) have clogged (although I changed them only about 40 hrs ago).

I put some Diesel 911 and another antigel additive in the fuel plus I've ordered a couple of Oregon replacement filters from Amazon. Hopefully the combination of those things will get me going for the spring.

Makes sense. Let us know how that works.
