Why is my Kubota B2620 Tractor engine difficult to start?
- C
  Crystal RogersJul 30, 2025
  There could be several reasons why your Kubota Tractor engine is hard to start. It might be due to no fuel flow, so check the fuel tank and fuel filter, replacing the filter if needed. Another cause could be air or water in the fuel system; ensure the fuel line coupler bolt and nut are tight. Also, weak battery can be the reason. Clean the battery cables and terminals, charge the battery or, in cold weather, remove the battery, charge it indoors, and install it only when you're ready to use the tractor.

What to do if Kubota B2620 Tractor exhaust fumes are colored?

  Kevin AdamsAug 6, 2025
  Colored exhaust fumes from your Kubota Tractor can indicate several issues. Poor fuel quality is a potential cause, so change the fuel and fuel filter. Too much oil can also be the problem, so check the oil level. If the inside of the exhaust muffler is dumped with fuel, heat the muffler by applying load to the engine. Also, the air cleaner could be clogged, so clean or replace the element.
