A couple weeks ago it turned over fine but the battery was too,low to crank it. I got the neighbor to tow it back to the house and I tried to crank it by towing it in 7th gear... it just slid the rear tires. I put a hot battery on it and it turned maybe an 1/8 of a turn and that"s it. I have a question... is there a special wrench to remove the injectors? I"d like to remove them and turn it over a couple times to see if it is hydraulic lock. Is there another way to do this? [Reply]   [No Email]

I don't understand how the injector is actually put together... I do understand how it works. I think I'll try something else. [Reply]  [No Email]

Start with the one exhaust valve that is sure to be in lash adjustment position, so watch how far you have to turn that one in to get to zero, then on a bit more, then turn in the other five the same amount.

I kept trying to think about a way to hold a valve open manually (with someone's help), never dawned on me to adjust the lash to hold the valve open slightly. Seems like the easiest thing to do since I'm an old drag racer, I've adjusted the lash 1000's of times. Thanks for the "rather obvious" help! [Reply]  [No Email]

I pulled it in gear with the trans in 7th. Since I was going down hill behind my neighbors tractor, I had to use the cluth/in gear braking to keep from running over the tractor pulling me (no hydraulics for the brakes). Only slid the tires a couple times to try and crank it, pretty easy to tell something wasn't right. I'm not worried about this tractor, paid $1,500 for it 5 years ago... and $1,500 for a rotary cutter, we've got our monies worth. I'm glad you gave me the heads-up on potential damage... If I didn't put the nail in it's coffin, I'll remember not to tow it from now on... Thanks [Reply]  [No Email]

Usually bends rods and breaks cranks, and sometimes trans parts. You will have better luck pulling the injectors for sure. [Reply]  [No Email]

I thought maybe the compression was too high to pull start. When I did put the hot battery on it and figured it was locked up... bent rod was my first thought. I figure the rods are pretty beefy... I'd be surprised if it's damaged. Maybe so, but I hope not, [Reply]  [No Email]
