Mower having a parking brake
A mower having a chassis, wheels for moving the mower in a mowing plane, and a cutting deck. The mower includes a parking brake having at least one brake member secured to the cutting deck. The cutting deck is mounted on the chassis so as to be able to move between at least one mowing position and a position in which the mower is stopped, in which the brake member comes into contact with at least one wheel of the mower so as to immobilize the wheel. The invention is intended in particular for use with mowers of the walk-behind or ride-on type, and with robotic mowers.
1. A mower comprising:
a chassis;
a plurality of wheels cooperative with said chassis and adapted to move said chassis along a mowing plane;
a cutting deck movably mounted on said chassis between at least one mowing position and one immobilizing position; and
a parking brake having at least one brake member integral with said cutting deck, the at least one brake member contactable with at least one wheel of said plurality of wheels so as to immobilize the at least one wheel when said cutting deck is moved from the at least one mowing position to the one immobilizing position.
2. The mower of claim 1 , said plurality of wheels comprising a pair of rear wheels having a fixed axis of rotation relative to said chassis, the at least one brake member comprising a pair of brake members respectively contactable with the pair of rear wheels so as to immobilize the pair of rear wheels.
3. The mower of claim 1 , wherein said cutting deck has a freedom of movement between the at least one mowing position and the one immobilizing position, said cutting deck having a component of movement parallel to the mowing plane.
4. The mower of claim 1 , wherein said cutting deck has a freedom of movement between the at least one mowing position and the one immobilizing position, said cutting deck having a component of movement perpendicular to the mowing plane.
5. The mower of claim 1 , wherein said cutting deck has a freedom of movement between the at least one mowing position and the one immobilizing position, said cutting deck having a component of movement parallel to the mowing plane linked to another component of movement perpendicular to the mowing plane.
6. The mower of claim 4 , wherein the one immobilizing position is at a lower position of said cutting deck.
7. The mower of claim 1 , further comprising:
a parallelogram suspending said cutting deck to said chassis.
8. The mower of claim 1 , further comprising:
a mechanism that manually shifts said cutting deck between the at least one mowing position to the one immobilizing position.
9. The mower of claim 1 , further comprising:
a latch cooperative with said cutting deck so as to selectively lock said cutting deck in the one immobilizing position.
10. The mower of claim 9 , wherein the at least one mowing position comprises a plurality of mowing positions, wherein said latch is an indexed latch, the indexed latch configured to lock said cutting deck in one of the plurality of mowing positions.
11. The mower of claim 1 , further comprising:
an actuator cooperative with said cutting deck so as to shift said cutting deck between the at least one mowing position and the one immobilizing position.
12. The mower of claim 1 , wherein the at least one brake member is a pad.
13. The mower of claim 1 , wherein the at least one brake member is a lug.
14. The mower of claim 1 , wherein said at least one brake member cooperates with one of the a rim, a hub and a tread of the at least one wheel.
15. The mower of claim 1 , wherein said cutting deck has at least one cutting blade, the mowing further comprising:
an electric motor drivingly connected to the at least one cutting blade.
16. The mower of claim 2 , further comprising:
an electric motor coupled to the pair of rear wheels and adapted to move the mower forward.
17. The mower of claim 5 , wherein the one immobilizing position is at a lower position of said cutting deck.
