H1502 Wont go!

[spanky350]

Here goes,

So I got this nice Bolens tractor w a Woods 48 in mower on the back. It runs great and only has 700 hrs on it. The guy i got it from said the 3 point wasn't lifing that great, so far i changed the hydro fluid twice, filter and cleaned both screens (front and back) On top of the 3 point not lifting (it goes a little bit but won't lift the mower--- (it will stay up if I get in the back of the mower and lift it) I was mowing the other night and it started acting up and whining quite a bit and now I have no reverse or drive! I barely made it back in my garage. I'm at a loss, is it the pump or something deep inside the huge drivetrain section?? Any help is much appriciated!!

Hi,

I wish that I could help you more, however I am not that familiar with the Hydro Tractors. If someone can help offer insight, there are quite a few parts for sale on eBay right now for your tractor: Bolens Iseki 1502H Mitsubishi 15HP Crank Gear | eBay

The 3PH should be able to lift close to 900lbs, and the mower shouldn't be an issue. I wonder if you can test the pressure that the hydraulic pump is producing. What type of hydraulic oil are you using? Sorry I couldn't be more help with the drivetrain issue!

Using napa tractor oil, I didn't really think it would matter much due to the age of the tractor. Am I wrong?? Also, I added a little fluid to it, not it reads that i have way too much in there and i have drive to the wheels but the 3 point still wont lift the mower. It just seems like i'm missing something simple....

The NAPA fluid should be fine for your tractor, but I would make sure that you don't have a leak. Make sure to check the dipstick located near your left foot. I posted a link in another thread that may help a bit:http://www.tractorforum.com/f205/bolens-g174-hydraulic-lift-problem-24600/

It may be an issue with the hydro, but I don't have a manual for your model. You can also try giving Sam a call from Sam's Bolens. He is very knowledgable about these tractors, and he can usually supply the parts that you need if you do need something. His number is at the botoom of the page:

It could be the hydro or there is a splined coupler before the hydro that goes bad.

So the tractor has been at the shop for a week now and i don't think they've even looked at it yet, the mechanic said it sounded lieks omething simple so i gave him the hydro manual and left it there. I did just see that there could be some air it the lines and maybe cracking open the hydro filter and/or some lines could potentially get it all going, any thought??

 

[Ilikeurtractor]

Could be. I'm not familiar with hydros either but wouldn't think you'd need to purge the air out of any lines to make it work after the correct amount of oil is in it. If so, this should be clearly stated in the opertor's manual.

Does the pto work?

 

[spanky350]

Nothing in the manual about bleeding the lines, and the pto work fine.

 

[lens12]

If the pto works, then the problem is in the hydro. I believe the manual has test procedures for it.

There is a hydro repair manual on eBay right now, it might really help you!

Still no luck. It sat at my friends shop for 3 weeks waiting for his hydraulic "expert" to look at it. I told him to just fix it, no favors, just fix it. I went to pick it up and he said I needed to make sure the hydro oil cooler wasn't clogged" wtf??!! I took it home and made sure the cooler wasn't clogged, it's not, and lifted the tractor, started it and cracked every hydro line I could get to one at a time and still nothing. The guy did tell me the tractor has 2 hydro pumps, one for the 3 point lift and one for the drive. He said I definitely have a lot of air in the lines but doesn't know where it's coming from. He also said it is rare that both system would go at the same time except if there was a huge lack of fluid in the system and it kept being worked, in that case both pumps would have to be replaced. No idea where to go from here, think I might try a place that works on tractors this time.....
