Kubota L2501 Dyno Results ~ More Timing, More Fuel, & More Power!

2020 Kubota L2501 was lucking some serious power... I Believe we have correct the problem! Adjusting the timing and fuel made this thing a beast! Max torque was made in the 2200 rpms range, while max hp peaked at 27 pto hp at 2500 rpm. I did notice slightly higher egt temps in the 2500 rpm range. More testing coming soon!
Tractor: L2501 Gear:
Stock Pto Hp: 20.5
Modded Pto HP: 25 ~ Peak 27hp

It’s not hyperbole to say that I have been waiting for this video like a kid before Christmas. That was awesome to see a 25% increase in PTO power from just the timing and fuel. Thank you for the hard work man.

I always wondered how much the PTO angle affects those readings. You had a huge angle going on there, and that would affect the reading greatly. Unless it was compensated for in the calcs. Bet it was actually slightly higher if the shaft was straight in. Prolly not by a huge amount, but could have been a couple horse legitimately. 💪

@@RaztechPowersports oh yea liked that one also. As l recall that unit was a 4 " banger" :: a smooth operation. Just no real reason to over power a new tractor and send it to the junk yard before at least 500 hours of proven performance happens. This was a "brave move" for the Public improvement seminar to deleat your warrenty.

Excellent work. I’m curious if it is possible to achieve an HP increase on my tractor. It’s does a great job now doing everything I need it to do but a bump in power is always nice. I have an LX2610SU. Thanks

I have a JD 1025r we finally got a turbo kit out, and with that guys are throwing more fuel at them and making 15psi. I love these little diesel’s I’ll probably wait till i get 100 hours before i throw a turbo on mine but in the interim Ill crank up the fuel a bit as changing the timing is a real bore. Even if its 2-3hp it’s worth it you just don’t wanna roll coal that doesn’t do shit just waste money Great video

I'm waiting on my new egt sensor, did this a while back but the cheap egt sensor sucked so I didn't tune it yet. In the process of removing my fuel screw it moved too much so I've gotta figure out the tune. Just screw it all the way in and start slowly doing 1/4 turns until the temp goes up , then back off?

I have the very same tractor. Gear drive and ag tires. The difference between the gear drive and hydrostatic as far as pulling power is unbelievable. The gear drive out pulls the hydrostatic badly.

@RaztechPowersports Жыл бұрын

Agreed! The gear drive spins all 4 tires in low range, regardless of the gear for loader work

I have hydro and you're making me jealous lol but I don't really need this for pulling. Mainly for spreading rock and around the house stuff. Small garden will be about the only real pulling I do. So I'm hoping I never come across the opportunity in which my hydro drive disappoints me lol

@@RaztechPowersports lol! Luckily I got 2 kubota z mowers to handle the lawn. But if I end up getting a bush hog for the 2501, your words might end up ringing in my head one day haha. Already feeling slighted now that I've seen comparison on hydro vs geared, but luckily I don't need the 2501 for any plowing or hauling 😅 for me it's more like having an electric shovel and wheelbarrow/rake because that's all I really need it for. But I'm sure over time I will find more things to use it for! And then I'll end up wanting more power haha

@76629online 5 ай бұрын

I wonder if anyone has put a small turbo on one of these? I feel like one of these engines is capable of 50hp. They certainly have enough displacement for it. Would probably over-power the gearbox then.

ITs torque x rpm. They are measuring torque at a specific rpm till rpm drops hence power drops.

I turned up my 2501 HST, one full turn on the screw. Running exact same conditions, she rolls coal under heavy load, max EGT just under 1300, very light smoke under normal loads. Its a completely different tractor to operate now. It was adequate stock, now its just a beast! Do it.

what are the max Temps for the exhaust? when you say 1 full turn out, is that from stock?

1350 - 1400 would be considered to hot and you would want to back off the throttle / reduce the load. Yes, one full turn out from the stock location.
