Introduction
The document is a job report detailing the use of the Liebherr PR 726 LGP crawler tractor by the company Schildecker, a specialist in sports grounds and lawn turf in Germany. The report highlights the tractor's application in preparing soil for high-quality lawn turf cultivation.

Company Background
Schildecker, located in Freiburg, Germany, specializes in refurbishing sports grounds and cultivating lawn turf. The family-run business, founded nearly 30 years ago, employs a core team of seven, expanding to 25 during peak seasons. They manage approximately 40 hectares of land for turf cultivation.

Task Description
The task involves preparing a special soil mix, primarily composed of sand, humus, and organic matter, applied to a depth of 20-30 cm. The fields are ploughed to 50-60 cm, left fallow over winter, and graded in spring for seeding. The process requires machinery that minimizes ground pressure and provides high traction to prevent soil compression and water accumulation.

Solution
Schildecker chose the Liebherr PR 726 LGP crawler tractor for its wide tracks, which minimize ground pressure while providing excellent traction. The tractor's features include proactive performance adjustment, stepless speed control, and a 2D laser control system for precise grading.

Performance and Comfort
The PR 726 offers sufficient power for heavy material handling and precise grading capabilities. The cab is designed for operator comfort, with ample space, an air-suspended seat, and excellent visibility. These features contribute to efficient task execution and operator comfort, even after long working hours.

Operational Details
The PR 726 is rented for 10-15 weeks annually due to seasonal demand. Schildecker collaborates with Liebherr dealer Michael Welte Baumaschinen-GmbH, maintaining a long-standing partnership. The machine's pushing power, traction, and grading efficiency are praised by company founder Franz Schildecker.
