Felt it important to upload information regarding a 10Amp Fuse Blowing on my TG1860 D. The problem first made its debut after an hour of cutting. The tractor stopped and all dash lights went out. The deck PTO also stopped when the engine stopped. After some initial examination found the 10 Amp fuse blown under the dash. Installing a new fuse allowed me to continue for about a half hour and it blew again. Let it cool down put in a new fuse and all seemed ok for a while and it failed again.
Noted that if the PTO clutch was not engaged, the fuse did not blow which meant the problem appeared to be in the power circuit for the clutch. Since the clutch seemed to be working ok and not slipping (while the fuse was still in tact), it initially didn't seem that the clutch was the possible cause. After measuring volts through the switches (Safety and PTO) theyall seemed ok. Ohmed out the Chutch and the resistance was low at 1.9 Ohms. DIsconnected the clutch at its connector. put in a fresh 10A fuse and all ran and worked fine. This pointed to the clutch itself having a problem or an intermittent issue. I should also disclose that my local dealer had provided me with the wrong drawings which added a couple of days and a bit to analysis before I realized what was going on. Messicks provided the proper schematic drawing along with detail on the clutch and the switches.
Les from Messick's confirmed my logic and a clutch was ordered. It was here from Messicks in a day and on the tractor that evening just before it started raining again. I had also ordered a PTO Switch only because the upper plastic retaining tabs on the original were broken off and the switch physically rocked when it was pulled out to be engaged. With the new switch and clutch all was troublefree again. Had to wait for the rain to stop a couple of days later to cut again for a good test.
Out side of normal oil changes, belts, blades and wheels for the deck have had no other notable problems since newly purchased many years ago (900+ hrs or so on the meter). All is good.
