Attacking that power problem CT225

bbse,at the time my dealer was installing my new snowblower,the mech. told me they had to install a new trans. in a tractor which souned about like yours.They say no reason for the failure but the new one fixed it.Nothing was seen to be the cause for it to not work.I agree that if your dealer isn,t going to help you go over his head to the big guys.Only thing is I hope you have a different dealer for future things cuz the old one probably won,t be of much help after being called out! Best of luck.These really are very good tractors,I,v used many brands in my life and bobcat is the best I,v used.As i said in a past post,if my grand dad had equip. this sweet he,d have never died.

There was a Kioti a year or two ago that had these same symptoms. They ended up replacing the HST, as I recall, and all was well after that. Stay after them. Good luck.

I remember reading this thread but I cannot find it now. If anybody remembers the key words and can find it I would appreciate a link. I am afraid it may be gone, wasn't there a crash a while back and some threads were lost?

well here is what my local bobcat dealer told me about using the mid mower and not having enough umpf to go up a small incline in HST Medium

"We tend to think you are overloading the engine. Running in low range will help provide the drive torque needed for the terrain, and still reserve enough horsepower for the PTO. You should be using low range, to reserve engine horsepower for the PTO.
Hope this helps."

yeah lots of help!

That's a cop out if you ask me. The tractor should be able to do almost all functions in Mid range, as that is how mine works and I only have a couple extra HP to the PTO, plus, I think people are having this problem even when the PTO is not engaged right?

Mine will almost stall out going up a medium size hill with just the FEL on, no PTO engage. It won't stall out on a slight incline but it will slow down some. To bush hog up those hill I have to use low and even then let off the pedal pretty good on the thicker stuff. I'm not too surprised about that. It is the running unloaded performance and the fact it can't even spin the tires out on good solid dirt that to me indicates a real problem. Going to swing by the dealer in just a bit to check progress.

Just to make it clearer, I took my angle gauge today and a 2x4, went to my hill side and laid the board down on the steepest part of the hill I have tried in mid range it is just shy of 20 degrees. That is with 0 being level and 90 being vertical. Some parts were 15-18 degrees. Is this too steep to expect the CT225 to climb in mid range? My LK3054 will go up it in 6th gear(out of 8) with a loader, 5ft KK brush cutter, loaded tires and all. In 5th I can accelerate going up it. As I stated with the CT225 if I stop in the middle, around 18 degrees, I can't take back off again with the loader, a 6ft lightweight box blade and loaded tires. Seems real puny to me.

Went by the dealer today, their still saying it meets spec and they cannot see anything wrong. I am going to bring it back tomorrow. I if I still can't spin the tires or climb the hill, I am inviting them out with another CT225.

I posted this in your owning/operating thread as well:

1) When you have the tractor in lowest range, be it a gear tractor or HST, and you demand maximum forward power but prevent movement (against a large tree, or tied to something) one of two things will happen, right? The tractor will either A) spin one or more tires, or B)if your traction exceeds your power output the tractor will stall. If you are able to stall the tractor than your traction exceeds your power output. This will happen with both an HST and gear tractor, and I don't see this as a problem at all.

Many of the higher horsepower per pound tractors (JD, Kubota, etc.) have more power than traction in low range so they will instead spin the tires in the same condition.

If you had said the tractor will not spin its tires and the engine will not stall, then that would mean the relief valve in the HST has met its maximum power output. That could be normal operation or potentially point to a relief valve out-of-spec. But since the tractor stalls this does not point to a problem with the transmission. It is possible that the engine is not making it's rated power, the best way to test would be to find a tractor dynomometer. The higher output (CT 230, CT 235) may spin its tires in this same condition, but then again it could exceed the power rating of the HST and engage the relief valve.

2) What does the engine do in this condition? Does it (nearly) maintain RPM or does it stall? If it stalls, again you have more traction than power. If the engine maintains RPM the HST relief valve has engaged which may or may not be as designed. Although, 16-20 degrees is significant. You may simply need to use low range in this condition. It's possible that a gear tractor may be better suited for this condition because it will likely have at least one range between "low" and "mid" so you could travel a bit faster, though it still wouldn't be easy to begin from a stop while using the clutch...

Since you posted here also so will I.

I just brought the tractor home from Bobcat and it is still the same if not even a little worse. As to stalling. I can start at a touch of pedal to about 2/3rds before it starts to stall, applied slowly of course. The same on the hill side except on the hill as I give it just a little more than a touch it will shudder a bit but won't move. I just tried the tractor against a tree again and my fields are pretty soft right now. It has rained the last 2 days. I nearly stuck my truck and I left some bad ruts getting out. But the tractor will not spin a tire even on that soft ground. Either it is super weak or I have some super traction on near mud!

As to my Kioti being gear on that same hill, I have gone up it in 5th and 6th many times over the past 5 years and I agree I wouldn't want to drop the clutch in the middle but I have started at the bottom many times at idle and just drove right up that rise with no problems. That is what I meant by accelerate easily in fifth gear. I always line up straight first before I go up it if I have a lot of weight on the small Kioti.

This may be a really stupid idea, but if the dealer has a 225, could you not do a side by side right there at the dealership? I mean you could even hook them tail to tail with a logging chain, and you should be able to tell if there is something wrong right away.
