Tractor
Kubota L3700SU
I live in mountainous rocky tropical terrain and my tractor does a combination of bush hog and road work. The road work is accomplished with a Box Blade, Grader Blade and Landscape Rake. I'm one of those that changed the Hydraulic fluid at 50 hours and at 400 now, will change in another 50. When this tractor works, it works hard. Engine oil has been changed on schedule along with filter and coolant has been flushed and replaced. Fuel Filter changed and air filter, inner/outer cleaned regularly. The battery required replacement a year ago. All pins and linkages greased on schedule. The tractor was purchased new in the fall of 2010.

I currently have two problems and also need to replace the front 7-16 R1 tires. Problem 1 is a PTO wire that in spite of work, refuses to shift the PTO in or out. Problem 2 is a leaking seal on the LH side front wheel final drive. While I'm into the LH side I'm replacing bearings as well as the seal and will do RH side at the same time. Add some filters and here's what you might be looking at for accumulated maintenance cost on a hard worked 37 HP Kubota:

Total: Oil, Filters, SUDT, grease, coolant etc to date not including fuel consumed: $400.00
Total: New Parts and tires including inland freight to Miami. (I'll have ocean freight and duty in addition but that would not apply to most of you) $790.00

TC010-9960-0 ASSY SEAL OIL 2 EA
TD060-1282-0 BALL BEARING 2 EA
TD030-1282-0 BALL BEARING 2 EA
TC220-5765-2 WIRE, PTO 1 EA
TD020-4374-0. TIRE-7-16 FRONT R1 2 EA
TA040-9323-0. AIR FILTER OUTER 1 EA
HH164-3243-0 OIL FILTER ENGINE 1 EA
6A320-59930 (Fuel Filter (element only)) Quantity: 1

So call it @1,200 for maintenance materials, not including labor. At 400 hours that works out to $3.00 per operating hour your mileage may vary due to differences in work, terrain and type of soil/rock. I could fathom a wild guess and say that I have 100 labor hours invested in maintenance and repair so at $20 an hour (I work cheap) I have another $5 labor cost for every hour on the meter for a grand total not including fuel of $8 per hour.

I am highly satisfied with the tractor. The pasture Genia Grass can and does grow up to four inches a day with rain and the unpaved roads are half rock, half soil and most of the time I spend on them consists of repairs after torrential rainfall which can easily exceed 2" per hour. Just thought I'd share some costs.....

Always good to hear hard numbers. I've been budgeting about $10/hr for maintenance stuff. I upgraded from my L3200 to my L4060 at around 350 hours so never got to much maintenance costs there.
