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

You’re the man with the plan!

@aarondillon3880 2 года назад

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.

@RaztechPowersports 2 года назад

Thanks man and I’m glad it helps! I’m going to continue uploading as well. The power increase is very noticeable 🏁

Very Kool modification & power improvement. A turbo-super-charger & air inter-cooler would be the ultimate. Thank you for the great Video Sir and happy tractoring.

@RaztechPowersports 2 года назад

I turbo charged my last tractor with great results (L285) 🏁. I was tempted to do it immediately on my L2501 but decided to start with the basics and she what she could do 💪🏻

@donaldstrishock3923 2 года назад

@@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.

How was the added power bush hogging. Can u feel the difference. No more bogging down in heavy brush

@RaztechPowersports 2 года назад

@@davidmcgraw7887 I ran the finishing mower all day with great results. I did get the engine to load up and it never lost rpm. The bush hog will be the real test. I have a good thick area for next time

@GoGoggansGo 11 месяцев назад

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

@Longslyde1 7 месяцев назад

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. 💪

@johnconway8492 Год назад

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

@diesel7903 Год назад

That’s clean smoke it’s not bad to roll coal but it is when you can’t see the other side of the smoke

@RaztechPowersports Год назад

I actually just leaned it out a 1/4 of a turn. Egt temps were okay but I was rolling to much coal under a steady load (grass cutting)

@jram7047 Год назад

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?

@avines7566 Год назад

My b 7800 is 30 hp and does well

@tractortalkwithgary1271 Год назад

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 Год назад

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

@swappedoutZ71 Год назад

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

@txlonghornremodeling 9 месяцев назад

I love how you mentioned the tac cable. I’m on my 3rd one now on a 2022 L2501 with just 110 hrs. Other than that the tractor has been bullet proof.

@douglasbeck822 2 года назад

RAZZ- Thanks for the follow up and conclusion to the fuel pump timing MOD . What would rate you engine horsepower ??

@RaztechPowersports 2 года назад

I would say the engine at the crank is making 32 to 33 hp. The torque increase is very noticeable as well

@Unchartered_Outdoors 2 года назад

Nice numbers! I know you said you only had the ole butt dyno stock, but do you know what others have put out stock?

@RaztechPowersports 2 года назад

So it was rated at 20.5 Hp from the factory. Holding 25 is a nice % increase 🏁

@swappedoutZ71 Год назад

Finally. Someone who thinks like I do lol. I hook up everything i get my hands on. But I think I may leave my new 2501 alone for now 🤣

@swappedoutZ71 Год назад

@@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

Can you explain how you can measure horsepower at the PTO with a live PTO?

@OUTDOORS55 4 месяца назад

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

@76629online 3 месяца назад

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.

@grasscutter88 2 года назад

How do you measure the timing to see what it is for a baseline?

@RaztechPowersports 2 года назад

You have to pull the load bracket off to see the flywheel timing marks. It’s a pain

@RaztechPowersports 2 месяца назад

Turn that bad boy up. That HST eats up some power.

@bearswartz2907 24 дня назад

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.

Did you void your warranty?

@leadfoot1158 2 года назад

What do you think just adding timing without fuel would gain? Mine is set to run at 3000 rpm not sure if that makes a difference.

@RaztechPowersports 2 года назад

What engine is it? At 3000 RPMs you’re probably already at the limits honestly. The l2501 was very restricted from the factory

@leadfoot1158 2 года назад

Ditch Witch SK800 mini skid it has a D1105

@MrManic52001 2 года назад

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

@RaztechPowersports 2 года назад

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.

@travisconner1581 2 года назад

so does it smoke when you load it above 10 percent and above 800 for egts?

mine is stock and I don't get an ounce if smoke from it even in stock form.
