    How To Increase Mower Ground Speed TG1860

    You're probably right. A few years ago, I had a pair of rear tires picked out on Amazon that were a couple inches larger diameter than what's on it now. I have fender clearance and would have to re-balance the deck. They were a few hundred dollars, so I didn't think the little increase was...

    How To Increase Mower Ground Speed TG1860

    Hello, I have a Kubota diesel TG1860 54" belly mower that I bought new in May 2000. It now has nearly 800 hours on it, I'm averaging 32/hrs per year. The diesel engine still runs great, and everything remains solid. I mow 2.5 acres in under 2 hours with no trouble. My Biggest concern is the...

    TG1860 Mower with PTO Problems

    I used a 14mm fine-thread bolt, some 1/2" steel tubing I already had, and some PEX tubing and made a new heavy-duty vent tube assembly. I did use the Kubota top-piece filter to complete the assembly. The bolt was drilled 5/16" through then bored 1/2" diameter about 3/16 deep in the head. The...

    TG1860 Mower with PTO Problems

    This morning I got it put back together and then mowed 2 acres of grass. Everything is fixed, and it is running smooth. Thanks to all who provided assistance and for allowing me to think through this project. Now I know to keep an eye on this vent tube because at some point it will break...

    TG1860 Mower with PTO Problems

    1) I discussed this with the Messicks tech rep. He said to pull the ring up until it just about touches the disc. With the stepped sleeves on which this thing assembles there isn't any option to adjust the gap. With the ring mounted on the three studs I could pull up the lower disc to close...

    TG1860 Mower with PTO Problems

    Today I went to the local Kubota dealer to get the vent fitting and hose and little filter thingy. Yikes!! The plastic threaded vent fitting is $36, the 3" of plastic hose is $8, and the little plastic filter on top of the hose is $17. Parts # 370 & 380 & 360. Yikes! I'm going to reuse the...

    TG1860 Mower with PTO Problems

    When I apply 12v to the two leads from the PTO it clicks and locks into position. It's good. I picked up a spray can of CRC QD Electronic Cleaner to clean out the PTO. I wish I knew how to disassemble it so I could really clean the surfaces. I still need to test the switch but I'm believing...

    TG1860 Mower with PTO Problems

    I understand your aversion to using kero or diesel to clean the PTO as both of those have lubrication properties. Gasoline would be a better cleaner but it's flash point makes it dangerous to use in this fashion. I'll use the brake cleaner. I used to use something called ElectroClean to clean...

    TG1860 Mower with PTO Problems

    This morning I removed the gearbox with PTO and they were a mess. I scraped off the excess oil soaked crud, then brushed with diesel fuel, then rinsed with water. I still have to clean up the underside of the mower. I was about to go to our local Kubota dealer across town to get oil, a vent...

    Who knows what kind of oil the gearbox requires? Might be a good idea to drain it and refill with fresh.

    TG1860 Mower with PTO Problems

    The vent hose is broken from on top of the gearbox located between the engine and the HST. The PTO is attached underneath this gearbox and is drenched in the oil that has splashed out. Tomorrow morning I should have this gearbox pulled from underneath. Other than replacing the vent hose and...

    Hmmm. I'll check the breather for a missing vent tube.

    TG1860 Mower with PTO Problems

    Today I rinsed off the mower before moving it into the shop to begin work. When I removed the RH deck belt-guard I found what looks like a vent hose attached to a broken off fitting. That's probably the reason for the oil splashed around. Now I'm concerned my washing off the dust and rinsing...

    TG1860 Mower with PTO Problems

    I own a Fluke multimeter but admit I am no expert with it. I'll need a wiring diagram to facilitate the necessary checking. I've considered the fault may be in the pull/push button switch and its replacement cost is much more palatable at ~$25. It seems to have 8 wires connected to it and if...

    TG1860 Mower with PTO Problems

    It seems the PTO is probably electromagnetic activated, and I didn't hear any thunk when it was activated with no results. It was like it was not receiving the signal to activate, so it could be the pull button. But the excess oil in the PTO area is suspect. I'll pull off the seat and body...
