G1800 Maintenance

[dlundblad]

Newbie Kubota Fan...


Since I do the mowing for my dad, I do some of the maintenance too. What can I say though, I love it... Well anyway, I noticed that on the G1800 the mower deck does not set level when it is raised all the way... Any theories? I think it may be that the springs are just a little stretched seeing how it it about 13 years old.

I also sharpened the blades and was excited to try it out. When I did, the mover still seemed to push some of the grass over and not cut it. My dad and I replaced the belt and the tension spring last year and that helped a little, but it still needs a little help... I know that it mowed way better than that when it was newer. Any suggestions on that?

Thanks, Dave

Hi Dave,

Well here's my first thought. Are the blades installed correctly? could they be installed upside down?

That is a big possibility. Is there a way of telling which way the blades go on? I just might have to go look at it, then I may be able to figure it out.

Dave,

The design of the blade in rotation should act to "lift" the grass as if "vaccuuming" it up just before it gets cut off.

Mower blades have their own language it seems, and it can sometimes be a little confusing.

Local colloquialisms and engineering terminology (such as “3-in-1” or "high-lift") have also contributed to this confusion.

Essentially there are only TWO basic styles of mowing blades used on or approved for use on Kubota Turf and Mower products:

1) The standard style of mowing blade is essentially designed for cutting grass and effectively discharging the clippings out from the deck to fall onto the lawn or to be captured in a grass collection system.

Standard blades are also referred to as “2-in-1” (discharging & bagging ) 244or “high-lift” blades (because they are designed to create a higher-lifting airflow).

2) Mulching blades245 generally have a more curved style surface and frequently include extra cutting surfaces along the blade edges. These blades may also come in a “+” design (which is actually two individual blades arranged in a perpendicular fashion to enhance mulching).

The “+” blades are usually found on older style mowers; newer ones utilize blades with more advanced mulching technology.

Mulching blades may also be referred to as “3-in-1” (mulching, discharging & bagging) or “all-purpose” blades.

Bear in mind that the re-circulating airflow design of 3/1 blades makes them less efficient at discharging grass clippings than a standard 2/1 blade. As with most all-purpose tools, there is some give and take as opposed to using a tool designed for a more specific purpose.

If you’re experiencing less-than-desired cutting or discharging performance with a 3/1 blade, you may want to check into using a 2/1 blade. Conversely, if you’re using a 2/1 blade and want to mulch clippings, you should see about the availability of mulching blades or a mulching kit* that may be available for your Kubota Deck.

* MULCHING KITS – These generally consist of mulching blades and a mulching plug (which closes off the discharge opening to keep the clippings contained under the deck for re-cutting) plus any necessary hardware for installation.

Take a look at the blades you have on the deck now to see if they will be rotating in the direction of travel that puts the sharp edge in contact with the grass. If not, flip them over.

You can adjust the deck for level by adjusting the yokes on the front bars from which the deck hangs.

The way I tell if the blades are on correctly on mine is that there are little wing tips on the ende of the blade. these must be on the top. otherwise the tips will tear at the grass below the cutting plane.

With that, I have the pins in the same position on both sides of the deck, so I think the springs may just be stretched.

And I checked the blades and they were on correctly, so anymore suggestions?

And thanks for the replies so far.:)

Mow forward, not in reverse??

I'm stumped now
