Career
Born in Salford, Greater Manchester he made over 300 appearances in the Football League between 1956 and 1971 before dropping into non-league football. Hartle was spotted by Watford while playing in a local park as a schoolboy and agreed terms as a junior in 1956. Having impressed in the lower divisions, Hartle was signed by Division Two side Sheffield United for £2,750 in June 1960, but only made three competitive appearances during his first season with the Blades.
However, following United"s promotion to Division One Hartle began to feature more regularly, although still primarily used when other team-mates were unavailable.
lieutenant wasn"t until the 1964-1965 season that Hartle established himself in the first-team, playing in all but three of United"s competitive fixtures that season. A year later however, Hartle was sold to Carlisle United in July 1966 for £14,900, representing a large profit on Sheffield United"s initial investment.
Hartle only remained at Carlisle for just over a season, joining Stockport County in September 1967. From there Hartle moved to Oldham Athletic in June 1970 before, after making just over 300 career league appearances, dropping into non-league when he signed for Southport in July 1971.
His career winding down, Hartle went on to play for Macclesfield Town, Buxton, Witton Albion and Hyde United before retiring in 1977.
Born in Salford, Greater Manchester, Hartle attended Salford Grammar School. After his retirement from football, Hartle was employed as a postman and then later as a taxi driver.
