2305 Stalls with rear PTO

[BobU]

I just got my Bear Cat Chipper out of storage but when I went to use it, the 2305 stalls when engaging the rear PTO. I'm used to a clutched PTO. How does the rear PTO engage on a 2305? How do I overcome the initial load on the PTO to keep the tractor running? Thanks.
BobU, new to this tractor.

are you sitting in the seat or have you jumped the saftey swich under the seat before you engage the PTO

There was another post in here regarding a 2305 and having to jumper the seat button. I just did it on my 4010 and posted the instructions. There's a thread on it. Apparently, the 2305 has a different button from the one on the 4010 though. Can't figure why JD did this on the smaller tractors, yet they allow it on the 4110, which is the same size as the 4010.

On my 4010, with the MacKissis or LX4 I rev to about 1500 rpm and then pull the PTO button up. Then rev to the 540 PTO rpm point.

I stay in the seat. I will jumper out the seat switch if/when I can get the chipper to run. It seems that the load on the PTO from the chipper is too great although the chipper is designed to run with as little as 13 hp. I rev the tractor to just under 1500 rpm and pull the switch and the tractor lugs down. I'm hesitant to rev more because the instructions say I shoouldn't and the PTO seems to engage with no slippage and I don't want to break it. Do you know how the PTO engages when you pull the switch? Is it hydraulic or gear or electric? Or am I doing something wrong?

Thanks for your responses.

Bob,

Is there some restriction in the chipper. My 2210 will engage the 62C MMM at idle with no protest, the same goes for my PTO spreader. /forums/images/graemlins/blush.gif

Just after you pull the switch, start raising the throttle slowy. You a a large flywheel you need to get up to speed.
The PTO engagement is hydroelectric.

I'll try raising the rpm when engaging. I don't have a problem with my 62" MMM although it does lug a little but never stalls. I can turn the chipper driveshaft with a large screwdriver and it is smooth and has no binds but it does take some power to get it going. I seems as though a hydo electric system wouldn't have severe strain on it when it trys to get the momentem going on the chipper flywheel. Kind of wish I could clutch it a bit but thats not possible. I hate to abuse the tractor but I'm going to assume that it can take it. Usually when I assume something, it doesn't turn out too good!!

Thanks for the suggestions.

My 2210 runs my rear PTO trac Vac and 62c mower at the same time. The trac vac needs a minimum of 16 hp at the rear pto shaft.

The guy who delivered my MacKissis apparently didn't know about the PTO and seat button problem on 4010s. He tried raising the speed all the way to 3,000 rpm before engaging the PTO. Of course, it died each time because of the seat switch. We ended up tying the seat down with some tension cords I use on the turnbuckles for the 3 pt.

One thing that I used on my 4010 before fixing the seat button was a stiff piece of plastic over the seat button, taped down with masking tape.

I'd check your chipper to make sure there isn't something binding in it. My MacKissic has a fairly large flywheel. It'll start going without stalling the tractor with the speed set at 1500 rpm. It's designed for 10-30 hp tractors; I think. It looks basically the same as the one they have a 10 hp engine on.

BobU,

I believe our tractors use an electric solenoid to apply hydraulic pressure to a wet clutch inside the transaxle. I would think it would be OK with your chipper. I have a 450 tiller that was built for the older 400 models (425,445, 455) that I now use with my 2210. If I hit a large root or stone when using it with my old 445, it would stall the tractor at full power. Now with the 2210, it will actually slip the clutch on the tiller’s PTO shaft.

I think the correct approach would be to increase your RPMs gradually or start increasing the power just as you trip the PTO switch. You want enough RPMs to create enough hydraulic pressure to run the PTO circuit so that you don’t slip the wet clutch anymore than necessary, and you want the RPMs low enough so that you don’t shock the mechanical systems too severely at start up.

Let us know how it works,

John
