Pat is right about the collar being chewed up. They get that way because people shift the gears while the tractor is still in motion. Usually 3rd gear is bad. Are you sure the hand clutch is going forward all the way into high range? If it is perhaps you have disc problems with the hand clutch.

Your second gear problems are most likely internal,second gear,slider/collar is bured up causing it to jump out,eventually it will do this under load.

I looked at service manual for a 185 and only mentions a single speed PTO, asked more experienced techs at work and they said it's runs on a different shaft and gear,and if it's the same as the set up as the 540 being a clutch pack Or IPTO it could be a number of things I.E. bad gear or shaft.

My advice is do your homework grab a service manual with the correct 1000/540 and read it and ask questions with your nearest dealer.

If they are nice enough to answer your questions for free,buy your parts from that dealer!

Pat, I believe he's not refering to a two speed pto, those tractors have a high low range hand clutch- very similar to the torq assists on internationals. When you pull the thing back toward the operator it goes into low range, when pushed into the middle position it's nuetral, and all the way forward is high range. It's slipping in high range if I'm reading the question right. I don't know of the 185's having independant pto. Maybe some of the later ones do?

Today's Featured Article - Tractor Traction - by Chris Pratt. Our first bout with traction problems came when cultivatin with our Massey-Harris Pony. Up till then, this tractor had been running a corn grinder and pulling a trailer. It had new unfilled rear tires and no wheel weights. The garden was already sprouting when we hooked up the mid-mount shovel cultivators to the Pony. The seed bed was soft enough that the rear end would spin and slowly work its way to the downhill side of the gardens slight incline. From this, we learned our lesson sinc ... [Read Article]
