Servicing ?'s 3320/3520

[2YD]

Well I'm now going all in with a TLB in either the 3320 or 3520. Both are extremely nice machines and while I've been leaning towards 3520 and have priced aggressively for my area a friend of mine has raised concerns about turbo's. I know blah, blah, blah. Well since I own a turbo diesel truck I'm not to concerned about failure since it will probably occur if it does in the first year or so and be covered by warranty. But he also said that turbo tractors require more maintenance than their naturally aspirated cousins. He speaks from a commercial skid loader point of view which isn't necessarily apples to apples. So to all TBN experts of both models tell me, are my yearly service requirements any different in the two models; is there anything I have to do with a turbo'd tractor that I wouldn't have to do anyway with the aspirated one?

All the Best.

I think your friend is giving you bad advice...

To answer this question directly:

is there anything I have to do with a turbo'd tractor that I wouldn't have to do anyway with the aspirated one?

1. Let the engine cool down for a few minutes before shutting it down so the turbo and exhaust can cool down. On my truck I make sure the EGT is at 350* or lower...but OTOH this is not a bad practice without a turbo also.

2. Change oil at scheduled intervals or before. Dirty oil can kill turbo bearings fast-but again this is good practice with a non-turbo-ed engine also.

KennyD you confirmed what I already do with my truck as well on cool down and as for oil I suppose that as long as I stick to the owner's manual service guides I'm good to go.

Thanks

Two more great things about the 3520 aside from HP...better fuel economy and it's cool to listen to the turbo whine!

IMO its not the Turbo that causes 99% of "turbo problems"...its failure by the owner and/or operator to adjust their operating & maintenance habits to having a Turboed engine....Some people NEVER have Turbo/Engine problems...some people toast them on a regular basis. We've NEVER had a turbo failure on any of the Farm Tractors...

Like has been mentioned, the 2 biggest killers of turbos are Dirty Oil and Hot Shutdowns.

Diesels and turbo's arent anything new...they've been around for YEARS it all sorts of applications.....So its not like its a "newfangled gadget" I chalk up all the negative turbo talk to inexperienced people who are used to Gassers and Small Diesels...aka "Weekend Warriors"....

When shopping for my new machine, a turbo was on the list of "Must Haves".... that put the first strike on buying a Kubota before even going to the dealer....dealer accomplished strikes 2 and 3 within 15 minutes of me arriving on site..

Really? Because when I looked at the specs on jd.com it appeared the 3320 was slightly easier on the fuel consumption. Is there something I'm missing with real world usage...

All the Best

The turbo will be more efficient if you have the CAB version, operating with AC, and say a 72" MMM at the same time on a hot day, going up slopes - the turbo is better in situations like that for sure/ My situation in the summer.
