Jacobsen Turfcat Issues

cgutenschwager · May 12, 2013

Hi, I joined this forum because there appears to be several knowledgeable people here along with some fellow Turfcat owners. I recently bought a Turfcat at auction, it sounded great as they drove it across the block, only to find it has issues. I am not afraid of a little work, I'm pretty knowledgeable in mechanics and maching - enough to be dangerous! - I just need some help figuring out what to do. Here are the issues I'm working on first:

- pto will not stay engaged, I hooked a bungy cord on the lever to keep the blades on. Seems to be cutting fine once I do this. Is there a loss in flow or pressure to keep the valve engaged?
- Last time I mowed, I got about an hour into the job and the engine tried to die out like I ran it out of fuel...I changed the fuel filter and filled it with fresh fuel after unloading it from the auction. I have read posts that suggested changing the fuel line due to internal blockages or small cracks that could let in air. So I'll do that and update you all.
- I noticed a fair amount of engine oil leaking from the oilpan gasket when I run it for a few hours, so I'll be changing that in due time. Unless someone thinks it more of a priority.

I look forward to any input you all might have - Thanks, Cory

I guess I should post a picture.... here she is:

Looks good, I know you will like mowing with it since it is designed like my TORO, and like the Kubota F series.

Can't help with the PTO, but next time it starts to die, remove the fuel cap. If it picks up and runs, the fuel tank vent is plugged.

If you don't get any answers here try: General Lawn & Garden

Thanks Xfaxman, I already do like mowing with it, I knew that before I bought it. I was cutting my yard with a 42" lawn tractor, and just purchased a couple acres next to me, so I needed something bigger. I worked for a company while I was in college who ran 2) NH CM274's and a Hustler 440 with range wings and a host of other equipment. I will try the vent trick, but it ran for 4+ hours a couple days earlier.

If it's like a regular hydraulic valve(like a log splitter or something), it should have a detent ball and spring. if the spring is worn out, it will let the ball slip out of the detent on the shaft.

cgutenschwager · May 12, 2013

Don, that is exactly the type of valve!! I don't have must experience taking these apart, but am mechanical and willing to try. How would I know if the spring is worn out? Should I expect lots of fluid? Should I just take the valve off and send it to a hydraulic shop ($$$$)? I appreciate your guidance here.

Actually, I don't think any fluid contacts the detent. it usually runs dry, and the major problem is that water gets in causing rust. without actually seeing yours though, I can't be positive.

But if you look at your valve carefully, you may be able to see where the detent should be, and it may just be a screw that holds it in place.

But just to be sure.........JJ, hangs out in the Hydraulics forum. He may be able to tell you more than me.

Which turfcat do you have? we may be able to get parts diagrams online to help diagnose your problem.

cgutenschwager · May 13, 2013

Don, I have a t422d. I have found all the manuals on jacobsens website, they use product codes and mine ends in 129.

Well it was a rough night, I went out to mow a bit and it took several cycles of cranking and heating with the glow plugs to get her started - but - finally, she fired up. As the smoke was starting to clear, and the engine was warming up, she slowed down, sputtered out and died. I had the vent cap loose, so it wasn't that simple.

I did change a couple fuel lines and bled the system. When I was doing this, I noticed the valve on the filter bowl seems to have an odd side-to-side movement, could this be letting in air? I also noticed that no fuel was coming out of the fuel bowl when I had the hose off (I just wanted to check). Should this be pouring out, or does it get sucked through by the injector pump?

Any ideas would be helpful - or a D950 replacement! :thumbdown:
