Diesel Ride On Mower service

  For ride-on mowers with diesel engines (typically 3 cylinder Yanmar/Kubota engines but we also have worked on diesel V-twin engines) our service includes the following operations:

  • Perform all checks (on everything – look at & test everything)
  • Flush engine oil with X-1R Engine Flush (this helps break up any oil deposits and thin the oil out so it drains more easily)
  • Replace engine oil
  • Replace engine oil filter
  • Add X-1R Engine Treatment (a friction-reduction additive)
  • Replace fuel filter
  • Add X-1R Diesel Treatment (a fuel additive that helps clean fuel lines and treat the fuel for things like algae contamination)
  • Replace air filter (usually the exhaust on the engine blows dirt straight into the air take and the air filter gets dirty very quickly)
  • Grease all points
  • Sharpen blades
  • Test operate
  • Degrease & wash

Other more common maintenance items that are done every few years include:

  • Replace deck belt (transfers drive from engine to cutting deck)
  • Replace traction belt (transfers drive from engine to gearbox)
  • Replace idler pulleys (in both traction & deck belt systems – the bearings wear out and as they are integral with the pulley we replace the whole unit)
  • Replace spindle bearings (the blades are attached to the spindles – again the bearings wear out but these are able to be replaced themselves)
  • Replace blades (they can only be sharpened so many times before they are too worn down).
  • Replace HST filter – HST = Hydro-Static Transmission (a type of single gear forward and reverse transmission – a bit like an automatic transmission in a car).
  • Replace battery – typically every 3 -5 years. Cold weather and infrequent use will cause them to wear out quicker – regular starting and running through colder/infrequent use periods will help maintain it in good health. Checking & topping up the individual cells with deionised water to the correct level (unless it’s a maintenance-free battery) will also help maintain it in good good health and last longer.

Being diesel engines they may also require the glow plugs to be changed – typically indicated when very difficult to start.

Some models (such as the John Deere X748 and Kubota GR2110) are 4WD so they have front differentials – checking the oil level in this is an extra item we check. 4WD is a great addition if you have steep hills on your property and/or heavy loads to tow.
