摘要： A height of cut adjuster for a reel mower cutting unit (100) with a removable attachment includes a front roller (102) with a shaft (134) positionable in front of the cutting reel axis, and a roller bracket assembly (128) having a bottom bracket (132) removably attached to a top bracket (130) to provide a gap therebetween where the front roller shaft (134) is held. The roller bracket assembly (128) may be pivoted, and the top bracket (130) may be connected to the bottom bracket (132) in a different position further from the cutting reel (106), so that an attachment such as a conditioner may be installed between the front roller (102) and the cutting reel (106).

摘要： A reel mower cutting unit (100) having a cutting reel (112) with a horizontal axis is supported by a front roller (102) and a rear roller (104) in a mowing position. A lift arm may raise and lower the cutting reel (112) between a mowing position and a transport position. A pair of gauge wheels (116) is mounted forwardly of the front roller (102) at a front left corner and a right front corner of the unit (100). If the unit (100) is lowered to a sloped surface, the gauge wheel (116) contacts the surface and prevents the unit (100) from marking or damaging the turf.

摘要： A hydraulic leak detection system (100) includes a leak detection switch (112) responsive to a level of hydraulic fluid in a tank used by a hydraulic mowing circuit (108) and a lift and lower circuit (109) of a grass mowing machine (102). The system includes a controller (128) that activates a warning indicator (130) if the leak detection switch indicates the level of hydraulic fluid in the tank is low, but allows the hydraulic mowing circuit and the lift and lower circuit to continue operating until the lift and lower circuit reaches a fully raised position. A solenoid valve (116) may control the level of hydraulic fluid in the tank based on temperature of the hydraulic fluid.

摘要： An adjustable lift rate system on a grass mowing machine (102) such as a riding greensmower having a lift and lower circuit (109) including a plurality of hydraulic lift cylinders (120, 122, 124) to lift and lower a plurality of cutting units, and a controller (110) providing a current to a proportional solenoid valve (128) to bypass the hydraulic lift cylinders. An operator control (112) may be used to adjust the current to the proportional solenoid valve to adjust the lift and lower rate of the cutting units.
