My land has some slopes and hills that I just avoid. To add stability am considering adding a Bora 3.5" wheel spacer to each side of rear. Anyone tried spacers? If so, how well did they work and did they cause any maintenance issues. Thanks.
You did not mention if you have a MMM (mid mount mower) on your tractor. If you add wheel spacers, it may affect the MMM anti-scalping rear wheels. I know in some "B" series, individuals would install wheel spacers in order to increase space for tire chains, however would have to remove spacers when they reinstalled their MMM. Additionally, rear tire ballast would help in tractor stability on hills. If you have a FEL (front end loader) you always should have rear tires loaded and/or rear ballast.

fwiw I installed 3" spacers on my L3800 a month or so ago. Afterwards I tried to compute how much additional 'tip angle' was gained. Tip angle being the point of no return where the center of gravity of the tractor is beyond the edge of the tire. My estimation is I gained 2 or 3 degrees. Doesn't sound like much but its something. If I were to do it again it would be 5 or 6" spacers.
Shorty after I loaded my tires with 250lbs each of non toxic antifreeze. That 500 lbs made some additional help with stability. An even better gain was made in traction. Today I was able to plow with the back blade going up my driveway. I couldn't do that before.

I don't have a MMM, but it is a good point, as is the tire ballast comment. Thanks.
My main focus is making sure I'm not going to break something expensive by adding the spacers (axles, bearings, castings, frame, etc).
