The longest journey on a lawnmower is 23,487.5 km (14,594.5 miles) in 260 consecutive days by Gary Hatter (USA). Hatter started his drive in Portland, Maine, on 31 May 2000 and passed through all 48 contiguous US states as well as Canada and Mexico before arriving in Daytona Beach, Florida, on 14 February 2001. 

He rode a $11,500 (£8,000 at 2001 rates) stock Kubota BX2200-60 mower at a top speed of 14.5 km/h (9 mph), wearing out four sets of front and three sets of rear tyres whilst clocking up 14 miles per gallon on average. The retired ex-truck driver completed the journey to raise money for surgery to treat a serious back injury that has put him out of work since 1979. His diesel-powered mower had power steering and four-wheel drive, and was fitted with all the necessary lights and attachments to make it roadworthy. He encountered no mechanical problems on the journey except for routine maintenance and services.
