I have a '70 model Ditch Witch with a Continental gasoline engine. I use this tractor sporadically down South here on my place & it generally starts & runs well.
Recently, the machine felt like it was running hotter than normal & would eventually kill on its own. Only after letting the tractor cool down for 10 to 20 minutes would it start again & run fine until it would kill again, while feeling like it was very hot. Now our summer has been extremely hot & this temperature thing is based on my past 6 or 7 years of working this tractor as the only guage that works is the oil pressure & it has remained consistent. The oil & coolant levels are ok. The rear main seal does leak more than I'd like but still not severe.The tractor runs good in all other respects.
I'm thinking that it may be a vapor lock problem but & if so why would this start suddenly without any changes to the engine?
Any information would be greatly appreciated. Thanks.
P.S. Also, does anyone have experience repairing or adjusting the "crowd control" drive mechanism (used for crawl mode) on these old Ditch Witch trenchers? Mine has started chattering when you push the hydraulic control lever forward or aft & I noticed a little slack in the drive chain. Again, any help is appreciated
