Just what is the coverage on the tractor?
Its it just covered for liability, and vandalism/theft? Or is it covered for accidents like a roll-over or it catches on fire?
And if there is liability coverage.....say you are mowing and throw a rock through the window of a house and it hits someone resulting in $$$$$$ medical bills and/or death?
Its hard to compare just "tractor insurance" and a price. Because there are so many varying forms of coverage.
My "business" liability policy with $2m/$4m coverage that covers landscaper type work with the tractor was ~$600/year and adding the tractor with a stated value of $25k added $177/yr to the policy. That covers the off-property things like theft/vandalism, acts of nature, etc. Basically things beyond my own control. But wont cover equipment damage as a result of my actions. Driving into a lake, rolling down a hill, etc.
Just this year I amended my policy to include digging/excavation as well as added my mini-ex with a stated value also of $25k to my contractors list.
My total policy is now $1100/yr.
So to pay $700+ per year for ONLY tractor coverage seems steep. unless it is also written along with a general liability policy and/or includes the things like self-inflicted equipment damage.
