Reducing a tractor's HP?

[steveR]

Now here is a new one for you!!

Should be taking delivery of a low mileage Kubota 9960 next week. However, while it is the same spec as the similar 8560, the 9960 is rated at 102hp, as opposed to 85hp.

I do not need the additional 15hp and am wondering if the increase has essentially come from dumping more fuel into the engine? Is there likely to be any appreciable fuel saving in reducing the power output (if possible) by reducing the fuel supplied to the engine??

You'll just not be working the engine so hard anyway, so doubt it'll make much difference.

First of all, congratulations and happy motoring!

Secondly if that’s what the engine is set for you won’t make any noticeable improvement in fuel use by de-rating it. You may even make it worse.

Just sit back and enjoy your tractor

Unless your working it flat out it won’t make a difference

Well, when using a loader, long experience is that you are on and off the throttle all the time, always a fuel guzzler. Just wondered if it could be improved a bit...

I looked at various smaller tractors, old and new, but the consensus was that I needed the bigger, heavier machines to deal with weight on the FEL.

Thank 'ee kindly! Been somewhat shocked at the cost of tractors after several years since I bought one... Never bought 2nd hand in 45 years, but needs must!!

Maybe I'll just put a sock in the air inlet....

Bit of a longshot I thought

I find they drink the most when I up the revs for PTO work - if you don`t do a lot of high revs work you`ll no doubt be OK....

Nothing too power hungry these days!

Round baling, 3m flail which it will eat for breakfast and heavy 3.5m discs are the heavier duties, and trailer work*. To be honest, I have been doing most hay and round baling jobs recently with the 50hp compact, BUT weight and power are a necessity at times... The contract farming outfit have also got an even bigger combine which leaves a massive swath that I struggle to bridge with the small wheels and limited ground clearance!!!


*With the light workload, it should outlast me!!

Well that's a post I never heard before everyone seems to want more power.dont worry about it you might get jobs done quicker

It's ME that needs more power and oomph!!

I had thought about a 70hp tractor and getting it chipped, but just too lightweight..

But first for this forum an owner reducing the power!

In this case I would suggest making sure it has a 540E pto gear would save you more diesel than de-tuning, and be a lot more civilised when working with a light load on the pto.

It has, and was a must...

I doubt you would make any appreciable fuel cost saving (over and above offsetting the cost of remapping it downward). That has to be a first on here at least.

Don’t over think it, just use it as it was intended.

Put some debris in fuel filter, fill air filter with dust ,to reduce power.

pulling work will be able to go up a gear and lower the revs so biggest savings will be there.
pto work might use a bit more tho
loader work same thing higher gear and less revs
used. run a round baler behind a case 7210 used less fuel than having same baler behind a 5130

Just take off one of the twin beacons....or cb aerials.


So simple I’m surprised nobody has suggested it before!!
